Heatwaves across Europe and South Asia have dominated the news recently. But these events are really a surface expression of more fundamental changes affecting our planet: Earth itself is accumulating heat faster than ever before.

We lead a large international team of scientists who come together every year to provide an update on the state of the climate system. This year, we find that Earth’s energy imbalance—the difference between the amount of energy entering and leaving the planet—has doubled in recent decades and is now at record levels.

This extra heat is a key indicator of the pace and scale of human-caused climate change. In a climate unaffected by human greenhouse gas emissions, Earth’s energy imbalance would be zero...

The central estimate of the remaining carbon budget for 1.5°C is 130 billion tons of carbon dioxide (CO2) (from the beginning of 2025). This would be exhausted in a little more than three years at current levels of CO2 emissions, according to the latest Indicators of Global Climate Change study published in the journal Earth System Science Data, and the budget for 1.6°C or 1.7°C could be exceeded within nine years.

Prof. Piers Forster, Director of the Priestley Center for Climate Futures at the University of Leeds and lead author of the study, said, “Our third annual edition of Indicators of Global Climate Change shows that both warming levels and rates of warming are unprecedented.

“Continued record-high emissions of greenhouse gases mean more of us ...

The past century of human-induced warming has increased rainfall variability over 75% of the Earth’s land area—particularly over Australia, Europe and eastern North America, new research shows.

The findings, by Chinese researchers and the UK Met Office, were published in the journal Science. They provide the first systematic observational evidence that climate change is making global rainfall patterns more volatile.

Climate models had predicted this variability would worsen under climate change. But these new findings show rainfall variability has already worsened over the past 100 years—especially in Australia.

Past studies of the observational record either focused on long-term average rain, which is not systematically changing globally...

Researchers at the University of Virginia School of Engineering and Applied Science have figured out how to take a miracle material, one capable of extracting value from captured carbon dioxide, and do what no one else has: make it practical to fabricate for large-scale application.

The breakthrough from chemical engineering assistant professor Gaurav “Gino” Giri’s lab group has implications for the cleanup of the greenhouse gas, a major contributor to the climate change dilemma...
