2025 global climate highlights are out:
🌡️ 2025 was 3rd warmest year on record, 1.47ºC above the preindustrial level
📈 2023-2025 is the first three year period above 1.5ºC (according to ERA5)
🌍 The last 11 years have been the warmest 11 years on record

Biofuels are absurdly inefficient compared to electric vehicles.

A great piece in @ourworldindata.org

ourworldindata.org/biofuel-land...
Putting solar panels on land used for biofuels would produce enough electricity for all cars and trucks to go electric
The world dedicates a Poland-sized area of land to liquid biofuels. Is there a more efficient way to generate energy?

Very sad start of the year in Switzerland with so many dead & injured young people. My thoughts go to the families, their communities & loved ones. Many victims came from Lutry where I grew up and/or attended the gymnase de Chamblandes, my high school many years ago.

It appears there is no withdraw process for @ipcc.bsky.social, participation in which is voluntary, free and open to all UN and WMO members. So the Trump administration’s supposed withdraw means less than their June firing of all the staff of the State Dept’s Office of Global Change

The ESM forcing files for #CMIP7 #ScenarioMIP are now up on the Earth System Grid for the two advanced-priority scenarios High (H) and Very Low (VL). CMIP7 H is significantly lower emissions than CMIP6's SSP585 - and VL has more radical near-term decarbonisation than anything we had in CMIP6.

Learn more about this year's #BOTY and other big advances in science: https://scim.ag/493Tpgx
Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

NCAR is quite literally our global mothership.

Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

Unbelievable.
