“we seek to speak candidly to fellow scientists, policymakers, & humanity at large. Given our roles in research & higher education, we share an ethical responsibility to sound the alarm about escalating global risks”

key highlights needed 3 screenshots

academic.oup.com/bioscience/a...

Key Highlights. (See main text for data sources.)
• The year 2024 set a new mean global surface temperature record, signaling an escalation of climate upheaval.
• Currently, 22 of 34 planetary vital signs are at record levels.
• Warming may be accelerating, likely driven by reduced aerosol cooling, strong cloud feedbacks, and a darkening planet.
• The human enterprise is driving ecological overshoot. Population, livestock, meat consumption, and gross domestic product are all at record highs, with an additional approximately 1.3 million humans and 0.5 million ruminants added weekly.
• In 2024, fossil fuel energy consumption hit a record high, with coal, oil, and gas all at peak levels. Combined solar and wind consumption also set a new record but was 31 times lower than fossil fuel energy consumption.
• So far, in 2025, atmospheric carbon dioxide is at a record level, likely worsened by a sudden drop in land carbon uptake partly due to El Niño and intense forest fires.
• Global fire-related tree cover loss reached an all-time high, with fires in tropical primary forest up 370% over 2023, fueling rising emissions and biodiversity loss.

• Ocean heat content reached a record high, contributing to the largest coral bleaching event ever recorded, affecting 84% of reef area.
• So far, in 2025, Greenland and Antarctic ice mass are at record lows. The Greenland and West Antarctic ice sheets may be passing tipping points, potentially committing the planet to meters of sea-level rise.
• Deadly and costly disasters surged, with Texas flooding killing at least 135 people, the California wildfires alone exceeding US$250 billion in damages, and climate-linked disasters since 2000 globally reaching more than US$18 trillion.
• Climate change is endangering thousands of wild animal species; more than 3500 species are now at risk and there is new evidence of climate-related animal population collapses.
• The Atlantic meridional overturning circulation is weakening, threatening major climate disruptions.
• Climate change is already affecting water quality and availability, undermining agricultural productivity, sustainable water management, and increasing the risk of water-related conflict.

• A dangerous hothouse Earth trajectory may now be more likely due to accelerated warming, self-reinforcing feedbacks, and tipping points.
• Climate change mitigation strategies are available, cost effective, and urgently needed. From forest protection and renewables to plant-rich diets, we can still limit warming if we act boldly and quickly.
• Social tipping points can drive rapid change. Even small, sustained nonviolent movements can shift public norms and policy, highlighting a vital path forward amid political gridlock and ecological crisis.
• There is a need for systems change that links individual technical approaches with broader societal transformation, governance, policies, and social movements.

No, that's the point, it's not: and when people treat it like it is, it sets up a faux conflict with other buckets.

#billgates got it wrong

great post, great comment section!

Katharine Hayhoe @katharinehayhoe.com · 1d

If you take the time to read the whole Gates memo (which I did), the bulk of the content was mostly solid and encouraging. Really!

It was the FRAME that was off--very off, from the first line.

And when your framing is off, then how you make decisions and set priorities is off. THAT'S the problem.

My quote from an Axios interview, stating that: People often think of climate change as a separate bucket at the end of a long row of other buckets of problems we're trying to fix that are wrong in the world," Hayhoe told Axios.
This includes poverty, disease and access to clean water.
"Climate change is not a separate bucket," Hayhoe said. "The reason we care about climate change is that it's the hole in every bucket."

I wanted to offer some thoughts on the Gates climate memo that has been circulating this week. While I can't directly speak for others, I can say that my own response is one of dismay & deep frustration (and that this view is shared by many climate/Earth scientists). [1/n]
