- 1Earth is heating at the rate of four Hiroshima bombs a second●Climate is accumulating 4 Hiroshima atomic bombs worth of heat per second
New attention is being drawn to the pace of global warming: the world's oceans and atmosphere are absorbing heat equivalent to roughly four Hiroshima atomic bombs every second. The figure, popularised by climate scientists to make ocean heat uptake tangible, is resurfacing as a striking illustration of how much excess energy greenhouse gases are trapping in the climate system.
- 2Oceans absorbed record heat equal to 40 times global energy use●World’s oceans absorbed record heat equal to 40 times annual global energy use
New reporting states that the world's oceans absorbed a record amount of heat in the past year, equivalent to roughly 40 times humanity's total annual energy use. Ocean heat content is a key indicator of climate change, as seas store most of the excess warmth trapped by greenhouse gases. The finding underscores accelerating global warming and its consequences for sea levels, marine life and extreme weather.

Cal Newport has published an essay arguing it is time to formally investigate the leading AI labs, such as OpenAI, Anthropic and Google DeepMind, over their rapid development of powerful systems. The piece is drawing attention on Hacker News, where readers are debating whether scrutiny of AI companies' safety practices and societal impact is overdue or already excessive.
