Space weather has been known to cause disruptions to GPS and communications systems, and perhaps no one is feeling those headaches more than farmers this weekend. 404 Media reports that the heightened solar activity over the last few days has led to outages in the GPS navigation systems that guide some modern tractors from John Deere and other brands. The technology has allowed farmers to plant more efficiently in ultra-tight, straight lines, but they’ve been advised to temporarily stop using it due to the potential for inaccuracies that could cause havoc down the line come harvesting time.

John Deere’s tractors connect to what are known as Real-Time Kinematic (RTK) systems, 404 reports, which allow for precision planting down to the centimeter level. If farmers were to go ahead and plant without their usual accuracy, “we expect that the rows won't be where the AutoPath lines think they are” when it’s time to tend and harvest the crops, Landmark Implement, owner of some John Deere dealerships, told 404 Media.

The timing is terrible — it’s peak planting season for corn, and one Nebraska farmer, Kevin Kenney, told 404, “All the tractors are sitting at the ends of the field right now shut down because of the solar storm.” Many farms have had to pause planting, while others are carrying on and just hoping for the best.

The geomagnetic storm we’re currently experiencing is the strongest observed in the last 20 years, and reached G5 levels on Friday and Saturday morning, which is considered to be “extreme.” It later died down some to G4/G3, but is expected to surge again on Sunday evening when some intense but slower-moving coronal mass ejections (CMEs) from the sun reach Earth. That’s great if you want to see the northern lights, but not so much if your livelihood depends on the technology the storm is interfering with.

The strongest geomagnetic storm in 20 years made the colorful northern lights, or aurora borealis, visible Friday night in areas of the US that are normally too far south to see them. And the show may not be over. Tonight may offer another chance to catch the aurora if you have clear skies, according to the NOAA, and Sunday could bring yet more displays reaching as far as Alabama.

The NOAA’s Space Weather Prediction Center said on Saturday that the sun has continued to produce powerful solar flares. That’s on top of previously observed coronal mass ejections (CMEs), or explosions of magnetized plasma, that won’t reach Earth until tomorrow. The agency has been monitoring a particularly active sunspot cluster since Wednesday, and confirmed yesterday that it had observed G5 conditions — the level designated “extreme” — which haven’t been seen since October 2003. In a press release on Friday, Clinton Wallace, Director, NOAA’s Space Weather Prediction Center, said the current storm is “an unusual and potentially historic event.”

Geomagnetic storms happen when outbursts from the sun interact with Earth’s magnetosphere. While it all has kind of a scary ring to it, people on the ground don’t really have anything to worry about. As NASA explained on X, “Harmful radiation from a flare cannot pass through Earth’s atmosphere” to physically affect us. These storms can mess with our technology, though, and have been known to disrupt communications, GPS, satellite operations and even the power grid.

Climate protestors in Germany broke through police barricades on Friday, amid clashes between activists and law enforcement. The protestors either made it onto (according to protestors) or near (according to local police) the grounds of a Tesla gigafactory in Grünheide, Germany, near Berlin. It’s part of a planned five-day demonstration ahead of a local government vote next week to determine whether Tesla’s plant can expand.

Wired flagged social media videos showing activists, many of whom have been camping out in treehouses in nearby forest encampments, running toward a Tesla building on the site. In addition, the German newspaper Welt said at least one person participating was injured. Police reportedly police used pepper spray and batons to try to thwart the crowd, and there were at least some arrests.

A spokesperson for one of the groups participating in the protests told Wired that they broke the police barriers and stormed the Tesla grounds. “Eight hundred people have entered the premises of the gigafactory,” Lucia Mende of Disrupt Tesla said. However, local police posted on X (Musk’s social media platform) that the activists only reached a field facing the site. “We have been able to prevent them from entering so far,” they posted.

At least at first glance, it’s easy to wonder why activists are pouring so much energy into fighting Tesla. After all, despite Musk’s increasingly unhinged right-wing conspiracy-mongering and Nazi-catering on X, other automakers pushing gas-guzzling cars seem like more appropriate targets (not to mention the fossil fuel companies spending big bucks on anti-climate-reform disinformation). However, several factors make the issues at the heart of the protests less simplistic.

A (nonbinding) vote in February showed Grünheide residents opposed the expansion by almost a two-to-one ratio. If for no other reason, the local government having a chance to brush aside the overwhelming will of the voters in the name of capitalism is enough to raise the eyebrows of anyone who balks at minority rule.

Wired notes the area is also one of the most water-scarce in Germany, and residents worry the gigafactory will drain the resource, leaving much less for the humans who live there. The plant could also pollute local water supplies.

Those fears appear to have merit: The plant is licensed to use 1.4 million cubic meters of water annually, and a separate Wired report from Tuesday noted that’s enough to supply for a large town. As for the contamination fears, Tesla was fined in 2019 by the EPA for several hazardous waste violations at a California factory. The company paid a grand total of $31,000 to settle. (Tesla had a market cap of almost $76 billion in 2019.)

But some of the groups protesting have concerns that go much farther than those more immediate issues affecting the locals, instead taking issue with the entire electric vehicle movement. “Companies like Tesla are there to save the car industry, they’re not there to save the climate,” Esther Kamm, spokesperson for Turn Off the Tap on Tesla told Wired.

Another activist, who only gave Wired the name Mara, described the factory as the result of “green capitalism.” She views the EV movement as little more than a theatrical performance in the name of profit. “This has been completely thought up by such companies to have more growth, even in times of an environmental crisis,” she said.

I wouldn’t exactly say flipping the bird to the EV movement is a “workable” solution to the very real and pressing climate crisis. Regardless of your thoughts on the matter, the world needs to move quickly to fend off climate change’s most ravaging effects, and the scientific consensus is that the planned shift to EVs will need to play a central role.

Tesla reportedly told its employees at the factory to work from home on Friday, shutting down the plants for the planned protests. As for Friday’s protests, Welt reports that the situation had calmed by afternoon — at least for now.

Swiss start-up Climeworks has done it again. The company just opened the world’s largest carbon capture plant in Iceland, dwarfing its own record of how much CO2 it can pull from the air. The company’s previous record-holding carbon capture plant, Orca, sucks around 4,000 tons of CO2 from the atmosphere per year, but the new plant can handle nearly ten times that, as reported by The Washington Post.

The plant’s called Mammoth and boasts 72 industrial fans that can pull 36,000 tons of CO2 from the air each year. Just like with Orca, the CO2 isn’t recycled. It’s stored underground and eventually trapped in stone, permanently (within reason) removing it from the environment. The plant’s actually located on a dormant volcano, so it’ll make a great hideout for a James Bond villain should it ever cease operations.

The location was chosen for its proximity to the Hellisheidi geothermal energy plant, which is used to power the facility's fans and heat chemical filters to extract CO2 with water vapor. After extraction, the CO2 is separated from the steam, compressed and dissolved in water. Finally, it’s pumped 2,300 feet underground into volcanic basalt. This compound reacts with the magnesium, calcium and iron in the rock to form crystals, which become solid reservoirs of CO2. It’s pretty nifty technology.

However, it’s not the end-all solution to climate change. It’s barely a blip. For the world to achieve "carbon neutrality" by 2050, "we should be removing something like six to 16 billion tons of CO2 per year from the air," said Climeworks founder Jan Wurzbacher, according to reporting by CBS News.

Therein lies the problem. This facility, the largest of its kind by a wide margin, can capture up to 36,000 tons of CO2 from the air each year, but that’s just 0.0006 percent of what’s needed to meet the minimum annual removal threshold as indicated by Wurzbacher. There are other plants, of course, but all of them combined don’t make a serious dent in what’s required to pull us from the brink.

To that end, Wurzbacher has pleaded with other companies to take up the cause. He says that Climeworks has a goal of surpassing millions of tons captured per year by 2030 and a billion by 2050. The company’s chief technology officer, Carlos Haertel, told 60 Minutes that scaling up the process globally is possible, but requires political will to rally behind the initiative.

The Biden administration recently committed $4 billion to jumpstart the industry here in the states and earmarked $1.2 billion for a pair of large-scale projects. The US Department of Energy also started a program called Carbon Negative Shot, with a goal of fostering the development of budget-friendly carbon capture technology.

The method of carbon capture deployed by Climeworks is just one of many approaches. These processes range from stacks of limestone blocks that absorb CO2 like a sponge to giant hot air balloons that freeze and trap the chemical compound. Restoring forests is another option, which is something companies like Apple and Goldman Sachs have experimented with. Which one is best? All of them together deployed at global scale. Whatever it takes. Climate change isn’t fooling around.

New research conducted by the University of East Anglia (UEA) suggests that current carbon removal plans will not be enough to comply with Paris treaty goals to limit global warming to 1.5C, as reported in a study published by Nature. Scientists came to this conclusion by measuring the “emissions gap” between various national climate protection plans and what is actually needed to reach that goal.

This first-of-its-kind study found a gap of up to 3.2 billion tons of carbon dioxide (CO2) between current global plans to remove carbon from the atmosphere and what’s needed by 2050 to avoid the worst impacts of global warming. These impacts include heatwaves, floods, droughts, melting ice and sea level rise.

Since 2010, the United Nations environmental organization UNEP has taken similar measurements of this emissions gap. UEA’s research, which focuses primarily on CO2 removal, indicates that climate policy requires a more ambitious scope if we are to, well, survive as a species.

This means a more nuanced and robust approach that still keeps current carbon removal practices in place, but with a renewed focus on cutting emissions, renewable energy and minimizing deforestation. There are also novel carbon removal options that many nations have been slow to discuss, let alone implement.

These include advanced air filters systems and enhanced rock weathering. The latter is a technique in which carbon is removed from the atmosphere and stored in rocks. These techniques account for the removal of just 0.002 billion tons of C02 per year, compared to 3 billion tons through conventional options. The research indicates that these novel options must become more prevalent in the coming years to help meet that 1.5C threshold.

“The calculation should certainly be refined,” said the study’s lead author, Dr. William Lamb, of the MCC Applied Sustainability Science working group. “This much is clear: without a rapid reduction in emissions towards zero, across all sectors, the 1.5C limit will not be met under any circumstances.”

Co-author Dr. Naomi Vaughan, of the Tyndall Centre for Climate Change Research at UEA, added that “countries need more awareness, ambition and action on scaling up carbon dioxide removal methods together with deep emissions reductions to achieve the aspirations of the Paris Agreement."

To that end, even if every country sticks to promises regarding carbon removal targets, the amount of carbon removed would likely increase by a maximum of 0.5 billion tons by 2030 and 1.9 billion tons by 2050. The latest Intergovernmental Panel on Climate Change (IPCC) reported that it would take a removal increase of 5.1 billion tons to avoid the worst effects of climate change. So, yeah, there’s that gap of 3.2 billion tons.

We aren’t doomed, at least not yet anyways. The IPCC suggests an alternative scenario in which the world’s governments work together to reduce global energy demand, hastened by “politically initiated behavior.” In this scenario, carbon removal would increase by 2.5 billion tons by 2050 and alternative methods would help tighten the emissions gap to just 400 million tons. So we basically have to shift our entire society from one of self interest to one of global cooperation. It never hurts to dream and, hey, maybe AI will swoop in and save us. 

If you've been thinking about picking up a new supercomputer but were waiting on a good price, now might be a good time to put in your bid. Right now, the US government, via GSA Auctions, is auctioning off the Cheyenne Supercomputer to the highest bidder with three days remaining. While we haven't tested this one ourselves, we assume its 145,152 CPU cores will easily out-perform our current top pick for a laptop. You also won't need to upgrade the memory anytime soon, as there's a full 313,344GB of RAM currently installed, and the storage capacity tallies up to around 36 petabytes. No need to delete files to make room for new games or other media downloads.  

The deal was spotted by Ars Technica, who also point out that the fiber optic and CAT5/6 cabling are not included in the sale. While the price the government paid for the supercomputer has not been disclosed, it's safe to assume the cost was well into the millions, considering the price tags of other supercomputers. As of this writing, the bidding has reached $28,085, though the reserve has not yet been met. There are still three days to go and there's currently no deposit required to place a bid. 

The reason for such a hefty discount (other than the fact that Cheyenne has been decommissioned) could be faulty quick disconnects causing water spray and the fact that approximately one percent of nodes have "experienced failure" and "will remain unrepaired." One other caveat to note before you start making room in your arena-sized climate-controlled garage is that shipping is not included. As GSA Auctions notes on the details page, "moving this system necessitates the engagement of a professional moving company" and that "the purchaser assumes responsibility for transferring the racks from the facility onto trucks."    

But where else will you find such steep savings on a machine that can carry out 5.34 quadrillion calculations per second? Cheyenne is also surprisingly energy-efficient, consuming 25 percent less energy per computation than its predecessor, Yellowstone. The massive supercomputer helped researchers understand the rapid intensification of hurricanes, how wildfires impact air quality, and simulated years of climate functions to predict outcomes decades in advance. It should definitely provide you with enough processing power for extreme multitasking at work while handling even the most demanding games after hours.

The Biden administration is tackling the monumental task of making America’s industrial freight system more environmentally friendly. The White House said on Wednesday that it aims to have 30 percent of industrial truck sales produce zero emissions by 2030 and 100 percent by 2040.

In addition to those non-binding targets, the White House is meeting on Wednesday with stakeholders from the commercial vehicle, shipping and infrastructure industries to help execute its agenda. The roundtable is designed to advance the Biden Administration’s goal of “supercharging the buildout of the infrastructure necessary to make a zero-emissions freight ecosystem a reality in the United States.”

Unsurprisingly, the freight industry uses a lot of energy and produces a lot of pollution to match. Bloomberg notes that the transportation sector emits about 29 percent of US greenhouse gas emissions, and freight (including shipping, trucking and trains) makes up about a third of that figure. So, you can ballpark that the American freight industry is responsible for roughly 10 percent of the country’s carbon emissions.

As part of the election-year rollout, the Biden Administration plans to ask the public to comment on charging infrastructure for heavy-duty vehicles, signaling that the specifics of the plan aren’t yet finalized. The White House wants to avoid a fragmented industrial EV charging system without a universally agreed-upon standard. The industry has seemingly settled on Tesla’s NACS as the de facto choice in the lightweight consumer sector.

Alongside the newly announced industrial goals, the Biden Administration’s Environmental Protection Agency (EPA) is opening up about $1 billion in Inflation Reduction Act (IRA) funding to replace Class 6 and 7 vehicles (school buses, garbage trucks and delivery trucks) with electric equivalents.

The IRA requires that at least $400 million of that funding goes to local communities hit the hardest by industrial pollution. The White House says 72 million Americans live near truck freight routes and bear the brunt of their short-term output. Sadly but unsurprisingly (given the nation’s history), people of color and those from low-income households are most likely to be heavily affected by high environmental toxin levels.

The White House’s goals are admirable, given the urgency of the global climate crisis and the freight industry’s role. However, one significant problem remains: These are voluntary, non-binding resolutions that could — and, given public comments, almost certainly would — be undone by a second Trump Administration, should the serial napper return to office next year. As with many other aspects of the nation’s and world’s future, US voters will decide the outcome this November.

On April 8, a solar eclipse will darken the skies. This is a rare astronomical event: The last North American total solar eclipse was on August 21, 2017, and there won't be another on visible on the continent until 2044. The path of totality — where the sun will be fully blocked by the moon — covers over 30 million people in the US, Canada and Mexico.

Those lucky folks may see the sun’s corona and a “diamond ring” — both dramatic sights. Other regions will experience partial eclipses, with the level depending on how close you are to totality. Watching the moon eat into the sun, even a bit, is still a spectacular sight.

So, which cities and regions will experience totality, and when? What’s the weather forecast in those areas? And if you do have a clear view, how can you safely watch and record the event?

Where in the US will you experience the solar eclipse totality, and when?

The good news is that many major centers are in the 100-mile-wide band of totality, so millions of people will be able to see a full solar eclipse. It follows a northeast path, so Mexico’s Pacific coast will get the first views in Mazatlan starting at around 10:57 AM PDT (total eclipse starting at 12:07 PDT), followed by the city of Torreón (all times local).

The total eclipse moves into the United states at 12:10 PM CDT (Eagle Pass, Texas), then hits Austin, Fort Worth and Dallas — three out of five of the most populous Texas cities. From there, it moves into Little Rock, Arkansas, followed by select parts of Missouri, Illinois and Indiana (including Indianapolis).

NASA

Ohio cities Dayton, Toledo and Cleveland get the full show, followed by Erie, Pennsylvania, then Buffalo, Rochester and Syracuse in New York along with Maine. Canada is in on the fun too, with parts of southern Ontario (Hamilton, Niagara Falls) and Quebec (Montreal) getting the totality, along with New Brunswick, PEI and finally, Bonavista, Labrador at 4:03 PM NDT (Newfoundland Time).

If you’re elsewhere on the continent and can’t travel, know that the closer you are to the band of totality, the more the sun will be obscured by the moon (this map shows how much of the eclipse you’ll get depending where you are on the continent).

An impressive list of major centers are within 200 miles of totality, so they’ll get a 90 percent or better eclipse (Houston, St. Louis, Memphis, Nashville, Chicago, Cincinnati, Detroit, Toronto, New York, Boston).

Anyone in the US south, midwest and northeast should get a decent spectacle, as will folks in Canada’s southeast and Atlantic coast. Even if you’re not in those regions, you might still see (and can capture) a mini eclipse.

How long with the 2024 solar eclipse last?

From the beginning when the moon first starts to cover the sun (partial eclipse) until the end when the two bodies part ways is a good long time – up to two hours and forty minutes in Dallas, and 2:18 in Caribou, Maine.

However, totality itself is brief, with the duration dependent on how close you are to the center of the totality band and the time of day. It’s at just under four minutes in Dallas, less than three minutes in Presque Island, Maine and a mere minute and 12 seconds in Montreal. As such, you’ll need to be ready and hope that the skies are clear during that brief window.

What’s the weather forecast in my area?

It’s still early for an accurate forecast, but a week is enough to get a general idea by region. Suffice to say, April isn’t the ideal month for clear skies. That said, an eclipse can still be visible through light cloud cover, and even if it’s thick, the sky will grow dramatically dark.

Unfortunately, the odds of precipitation are indeed above average across most of the band of the eclipse. Forecasts predict that the chances for clear skies are better the farther northeast you live, the opposite of historical trends.

To wit, Dallas has showers forecast throughout the day (58 percent), which would mean continuous cloud cover and no clear view if that holds. That improves a bit when you get to Indianapolis (partly cloudy, 24 percent chance of rain), with things better still in Buffalo, New York (partly cloudy, 11 percent).

Things are looking good right now in Montreal, though, with mostly sunny skies and only a 9 percent chance of rain, and the same goes for Fredericton, New Brunswick.

Niagara Falls also figures to have decent weather during the eclipse (mostly sunny, 18 percent) and is in the path of totality, which has led to the city declaring a state of emergency out of caution. Officials estimate that a million people could pour into the area, creating potentially dangerous crowds.

How can I watch the solar eclipse at home?

Staring at the sun is obviously dangerous for your vision, and doing so during an eclipse can be just as harmful. Even though you may not feel discomfort immediately, you may damage your eyes via an affliction called solar retinopathy. That can lead to serious consequences like eye pain, blind spots, blurred vision and more.

American Astronomical Society

To view it safely, you must purchase a pair of approved solar eclipse glasses based on an international safety standard called ISO 12312-2 (regular sunglasses won’t do). That dictates the maximum luminous transmittance, along with the range of permissible wavelength transmittance (UVA, UVB and infrared).

There’s certainly still time to grab a pair if you don’t have them already. The American Astronomical Society (AAS) has many recommendations for manufacturers and vendors, both online and at retail chains.

Warby Parker, for one, is offering free glasses (limit two per person while supplies last). You can also find them at Staples, Lowes and Walmart, or online at B&H and multiple science and astronomy stores.

The AAS advises against searching for the lowest price on Amazon or eBay, however, in case you get a bad knock off. “Before you buy a solar viewer or filter online, we recommend that you make sure that (1) the seller is identified on the site and (2) the seller is listed on this page,” it says on its Solar Eclipse Across America site.

How to watch the solar eclipse safely without glasses

Canadian Space Agency

It’s possible to view an eclipse without glasses via indirect means, as well. The simplest way is by punching a small round hole in a piece of thick paper or cardboard, then positioning it so the sun shines through the hole onto the ground or a flat surface (you can also attach a piece of foil with a hole, as NASA shows here). That will project an image of the Sun's disc, letting you see the eclipse in real time.

The same pinhole principle would let you use anything with perforated holes, like a colander, projecting dozens of tiny eclipses on a surface. Trees can do the same thing, casting weird leaf shadows with little solar eclipse chunks out of them.

For a bit better experience, you can build a crude box projector. With that, the sun shines through a hole in tin foil onto a white card, and you can look through a larger hole at the card, with the sun behind you. The Canadian Space Agency explains exactly how to make that.

Never, ever view an eclipse directly through a pair of binoculars or a telescope, as that’s a guaranteed way to damage your eyes. That said, you can use a pair of binoculars or a telescope to project the sun onto a piece of paper, as shown in this video.

How to take photos or video of the solar eclipse

Unfortunately, you can’t just point your smartphone or camera at the sun to record the eclipse, as the brightness will overwhelm the sensor and ruin the image (and possibly damage the sensor). Luckily, you can shield your camera just as you do your eyes.

The cheapest way to do that is to buy an extra set of eclipse glasses, then cut out an eyepiece from one and tape it over the smartphone (or other camera) lens. That will reduce the light levels enough to see detail in the sun throughout the partial eclipse and totality.

You can also purchase dedicated smartphone solar filters like the VisiSolar Photo Filter, which are designed for cameras and not direct viewing. Another choice is the Solar Snap Eclipse App Kit, which also offers an app that aids in photographing the eclipsed sun. It’s advisable to also wear solar glasses when setting up your smartphone or camera to protect your eyes.

If you’re shooting the eclipse with a dedicated mirrorless or DSLR camera, you’ll need either a mylar, 16-stop ND (neutral density) or hydrogen alpha solar filter. Again, do not look directly into a DSLR’s optical viewfinder at the sun if the lens doesn’t have one of those filters attached (the electronic viewfinder on a mirrorless camera is safe).

To photograph the eclipse with a smartphone, turn the flash off and put the camera into ultrawide or wide mode so it stays in frame. Do NOT look directly at the sun to line up your camera if you’re not wearing solar eclipse glasses.

Don’t use the digital zoom to try to make the eclipse bigger, as you’ll lose resolution (you can zoom in later in your photo editing app). Once focus is set on the sun, use your smartphone’s focus lock feature so that it doesn’t “hunt” for focus and blur the eclipse.

During totality, the “diamond ring” effect only lasts a split second, so use the burst mode of your camera or you’ll likely miss the shot. And try to capture RAW (rather than JPEG) images to keep the maximum detail possible for later editing. Some iPhone and Android smartphones have RAW capability built-in, if not, you can use a third-party app.

If you decide to capture video, you’ll need a filter as well, of course. But you should also use a tripod, as shooting handheld will induce blur and result in a shaky video. Even a cheap tripod will do the trick, along with a simple smartphone holder. Capture the highest resolution you can (4K or even 8K) at the highest quality possible. You’ll also capture any cheering, shouting, etc. — a precious souvenir you can look back on again and again.

More resources

There are plenty of government and private sites with more information about the eclipse, starting with the AAS’s eclipse site, detailing things like eye safety, imaging, resources and even a totality app — an “interactive map that shows what you’ll see at any location in North America for the total solar eclipse of April 8, 2024.”

NASA also offers a dedicated site for the North American Eclipse, as does the National Weather Service and National Solar Observatory. A private site called Great American Eclipse is largely commercial, but does have a very useful map showing the band of totality and how much of the eclipse you’ll see depending on location, along with a comprehensive list of eclipse times and durations by city.

Update, April 5, 12:30PM ET: This story was updated after publishing to include more details about the total solar eclipse's path of totality.

Last year was the hottest on record and the Earth is headed towards a global warming of 2.7 degrees, yet top fossil fuel and cement producers show a disregard for climate change and actively make things worse. A new Carbon Majors Database report found that just 57 companies were responsible for 80 percent of the global carbon dioxide emissions between 2016 and 2022. Thirty-eight percent of total emissions during this period came from nation-states, 37 percent from state-owned entities and 25 percent from investor-owned companies. 

Nearly 200 parties adopted the 2015 Paris Agreement, committing to reduce greenhouse gas emissions. However, 58 of the 100 state- and investor-owned companies in the Carbon Majors Database have increased their production in the years since (The Climate Accountability Institute launched Carbon Majors in 2013 to hold fossil fuel producers accountable and is hosted by InfluenceMap). This number represents producers worldwide, including 87 percent of those assessed in Asia, 57 percent in Europe and 43 percent in North America. 

It's not a clear case of things slowly turning around, either. The International Energy Agency found coal consumption increased by eight percent over the seven years to 8.3 billion tons — a record high. The report names state-owned Coal India as one of the top three carbon dioxide producers. Russia's state-owned energy company Gazprom and state-owned oil firm Saudi Aramco rounded out the trio of worst offenders. 

Exxon Mobil topped the list of United States companies, contributing 1.4 percent of global carbon dioxide emissions. "These companies have made billions of dollars in profits while denying the problem and delaying and obstructing climate policy. They are spending millions on advertising campaigns about being part of a sustainable solution, all the while continuing to invest in more fossil fuel extraction," Tzeporah Berman, International Program Director at Stand.earth and Chair at Fossil Fuel Non-Proliferation Treaty, said in a statement. "These findings emphasize that, more than ever, we need our governments to stand up to these companies, and we need new international cooperation through a Fossil Fuel Treaty to end the expansion of fossil fuels and ensure a truly just transition." 

If you're in the Metro Phoenix area — and don't mind walking out of your place to get your food delivery — your Uber Eats order may just get delivered by one of Waymo's self-driving cars. The companies have officially launched the next part of their ongoing multi-year partnership, which also includes offering robotaxi rides to the ride-hailing service's customers in the area. When you place an order on Uber Eats, you'll get a prompt that says "autonomous vehicles may deliver your order." 

You will be notified if a Waymo car does pick up your order, and you'll have to take your phone with you when you meet it so that you can open its trunk and get your food. Don't worry, you can opt out during the checkout process in case you're not feeling up to going out and getting your order and would rather have someone deliver food to your door. 

At the moment, Waymo deliveries are only available in Chandler, Tempe and Mesa, and only for select merchants, including local joints and chains like Princess Pita and BoSa Donuts. An Uber spokesperson told CNBC, though, that the companies are looking to expand their service area and are looking to add more merchants to their list. They also told the news organization that Waymo will be using its Jaguar I-PACE electric vehicles, which it's been testing in Arizona for years, for deliveries. It doesn't sound like Waymo deliveries will be more expensive either, since the spokesperson said you'll only have to pay standard fares and will not be charged for tips. 

The companies first announced that they were teaming up to offer robotaxi rides and deliveries in Phoenix last year, following Waymo's service area expansion in the region. Robotaxi rides became available in the metropolitan area by October, and you'll get the option to hail one when you request an UberX, Uber Green, Uber Comfort or Uber Comfort Electric.
