A megadrought spanning several decades could be almost certain to hit the American southwest this century if greenhouse gas emissions are not curbed.

A strong El Niño event and human-caused climate change created optimal conditions for the recent outbreak of the Zika virus in South America, research finds

Emissions of CO2 and methane from wetlands and thawing permafrost as the climate warms could cut the “carbon budget” for the Paris Agreement temperature limits by around five years, a new study says.

A widely reported study in 2016 that suggested Antarctica could add more than a metre to sea levels by 2100 was likely an “overestimate”, new research says.

Last year saw the rise of climate change protests, with Greta Thunberg, school strikes and Extinction Rebellion generating global news coverage.

At any one moment in time, thousands of measurements are being taken of the world’s weather.

The research develops a new complete record of Atlantic hurricanes from 1851 to 2019, adding in hurricanes that were likely missed by pre-satellite observation methods.

It is fitting, then, that the mammoth document – which forms the working group one (WG1) section of the IPCC’s sixth assessment report (AR6) – includes a dedicated chapter on weather extremes for the first time.

The “Conference of the Parties” (COP) international talks are the biggest climate diplomacy event of the year.

Almost 40,000 delegates registered for COP26 climate summit, the provisional list shows, suggesting that the Glasgow event is the biggest COP to date.

Carbon Brief has compiled its annual list of the 25 most talked-about climate papers that were published in 2021.

According to the UN’s provisional list, more than 33,000 delegates have registered for COP27, making it potentially the second-largest summit in COP history.

Last year brought no shortage of news. But in yet another hectic year for news coverage, climate change still made headlines.

Record numbers of delegates have been registered for this year’s COP28 climate summit in the UAE, making it potentially the largest in COP history

Using Altmetric data, Carbon Brief has compiled a list of the 25 most talked-about climate-related papers that were published in 2023.

At a meeting in Istanbul, delegates debated several different approaches for the work programme of the IPCC’s seventh assessment cycle.

The European parliament approved its law to restore nature despite recent protests from farmers across Europe, and more in climate news this week.

To help forecast hurricanes accurately, NOAA has a team of “hurricane hunters”, who gather data by flying aircraft directly into storms over the Atlantic.

In the early 2000s, a new field of climate science research emerged that began to explore the human fingerprint on extreme weather, such as floods, heatwaves, droughts and storms.

Carbon Brief reports on how “smart” surfaces can be used to cool cities in the face of worsening extreme heat.
