He is using his retirement to evangelize for the planet-saving advantages of hydrogen batteries.

On the East Coast, ...there’s just one. His name is Mike Strizki. He is so devoted to hydrogen fuel-cell energy that he drives a Toyota Mirai even though it requires him to refine hydrogen fuel in his yard himself. ...You can make fuel using water and solar power, .... The byproduct of making hydrogen is oxygen, and the byproduct of burning it is water. Hydrogen is among the most plentiful elements on earth, so you don’t have to go to adversarial countries or engage in environmentally destructive extraction t

The hole, scientists believe, ultimately penetrates more than a half-kilometer into the ice, joining a network of channels extending all the way to the base of the ice sheet. ...Covington and his colleague Jason Gulley, ...were motivated by a scientific question with enormous implications as the climate warms. Just how vast are these moulins, these ice caves found by the thousands across Greenland’s surface? How much are they undermining the integrity of the second-largest sheet of ice on the planet? And how much worse will it get as melting, and moulins, begin to extend farther and farther toward the airy center of Greenland, where the ice is well over a mile thick? ...As the climate warms — with the Arctic warming fastest of all — more and m

The debate now centers on just how bad things will get. But there are still major uncertainties when it comes to modeling future climate. Chief among them: How much more carbon dioxide will humans emit, and how sensitive is the climate system to all those emissions anyway?...To account for those uncertainties, the United Nations Intergovernmental Panel on Climate Change (IPCC) created several baseline scenarios, known as Representative Concentration Pathways (RCPs), to describe just how much warming might result from a range of carbon emissions. ...The most extreme model,  RCP 8.5 —sometimes ca

The need to study the real-world effects of releasing reflective particles is pressing, says David Keith, a Harvard energy and climate scientist and one of SCoPEx’s lead scientists.

Across the Rocky Mountains, Western monarchs have seen an even more alarming drop. Some of this collapse is tied to a need for milkweed, the only plant that monarch caterpillars can eat. Milkweed has declined across monarch breeding grounds throughout the United States since farmers started using crops that are ge

The Fed’s board in Washington voted unanimously to become a member of the  Network of Central Banks and Supervisors for Greening the Financial System , it said in a statement on Tuesday. The central bank began participating in the group more than a year ago, but its formal membership is something that Democratic lawmakers have been pushing for and that Republicans have eyed warily. ...The network exists to help central banks and other regulators exchange ideas, research and best practices as they figure out how to account for environment and climate risk in the financial sector.

Now, five tumultuous years later, a new slogan might be “travail en cours” (work in progress). That will be the implicit message sent tomorrow when nations gather—virtually—to look back on what the Paris agreement has achieved in its first half-decade and, more importantly, to unveil new pledges to further cut planet-warming emissions. Although analysts say the pact has helped make progress toward its goal of preventing average global temperatures from increasing by 2°C above preindustrial levels, the effort is also shadowed by ample evidence that many countries aren’t living up to the promi

Excerpt: The world’s wealthy will need to reduce their carbon footprints by a factor of 30 to help put the planet on a path to curb the ever-worsening impacts of climate change, according to new findings published Wednesday by the United Nations Environment Program. Currently, the emissions attributable to the richest 1 percent of the global population account for more than double those of the poorest 50 percent. Shifting that balance, researchers found, will require swift and substantial lifestyle changes, including decreases in air travel, a rapid embrace of renewable energy and electric vehicles, and better public planning to encourage walking, bicycle riding and public transit. But individual choices are hardly the only key to mitigating the intensifying consequences of climate chan

New research indicates the conflagrations are part of a pattern showing increased average burned areas every year since 1970, and climate change is poised to accelerate this trend.  Ellen Whitman , a forest fire research scientist from Natural Resources Canada, used historical records as well as satellite data from the  Landsat program  to analyze how the frequency, size, and distribution of forest fires in the province of Alberta changed between 1970 and 2019— research she’ll present  at AGU’s Fall Meeting 2020. She and coworkers from the Canadian Forest Service and the U.S. Forest Service found that forest fire activity in Alberta increased according to a plethora of metrics over the past 49 years, with the number of fires that consume at least 200 hectares of land almo

Climate change has transformed it into a region that can  heat up to 100 degrees , is beset by ferocious wildfires, and is covered in permafrost that is no longer permanent. The sea ice cover that has long defined the Far North is fast disappearing. This is the picture from a new international scientific assessment released Tuesday. The 2020 Arctic Report Card, a report led by the National Oceanic and Atmospheric Administration (NOAA) involving 133 scientists from 15 countries, points to trends that, with each passing year, have grown more extreme and have far-reaching implications for people living far outside the region, including in the Lower 48 states....

Little did they know the phenomenon was connected to winds swept up by the largest African dust storm on record—an event so massive, scientists have dubbed it Godzilla. These winds, researchers now report, were in turn triggered by a meandering jet stream that circles the planet farther north. The new findings identify yet another way in which a warming Arctic might disturb the weather half a world away. The root cause of the extra-wavy jet stream is under fierce debate, but some scientists believe Arctic warming and declining sea ice are to blame for Godzilla’s far-reaching effects. “Arguably there is at least an indirect connection between climate change and this notable dust storm,” says Michael Mann,
