The Latest Breaking News from James Hansen

Sea surface temperatures are rising with clear indications we're to blame

When 2023 ended, it was the hottest year in recorded history. So far, this year isn't looking much better

“Climate Crisis” only identifies the symptoms of oil and gas dependence. As time runs out, we need a term that focuses on what — and who — is to blame.

Getting to net zero emissions by mid-century is conventionally understood as humanity’s best hope for keeping Earth’s surface temperature (already 1.2°C above its pre-industrial level) from increasing well beyond 1.5°C – potentially reaching a point at which it could cause widespread societal breakdown.

The Guardian asks five climate experts to explain the key differences between 1.5C and 2C

State-of-the-art climate models suggest that we are not committing to decades of additional warming once we stop spewing carbon into the atmosphere. That means there's still time to stop the worst impacts of climate change.

We now have a very narrow window to significantly and rapidly slash greenhouse gas emissions to avoid the most disastrous effects of climate change, with just an estimated six years left before we blow our carbon budget to stay below 1.5°C of warming.

One of modern climate science’s pioneers is warning that the world isn’t just steadily warming, but is dangerously accelerating

James Hansen began sounding the alarm on climate change in the 1980s. The situation is only getting more dire
