Global Warming

The Observatory has forecast that Hong Kong’s annual mean temperature this year is likely to be above normal, with a strong chance of ranking among the top 10 warmest years on record. Presenting the city’s weather outlook on Monday, Observatory Director Chan Pak-wai said the warmer conditions are linked to…

It’s no secret our planet is heating up. And here’s the evidence: we’ve just experienced the 11 hottest years on record, with 2025 being the second or third warmest in global history. The annual State of the Climate report, published today by the World Meteorological Organization, suggests we’re still too…

Proceedings of the National Academy of Sciences, Volume 123, Issue 12, March 2026. SignificanceOne of the main goals of international climate change negotiations is to distribute the economic burden of limiting global warming. A central challenge is that some countries are wealthier than others and may therefore be better able…

A new study led by Chinese scientists has found that loss of sleep, particularly among children, due to rising heat driven by climate change may deepen global inequality and lead to economic losses. The study was published last Friday in Nature Sustainability, a subsidiary of the science journal Nature. Researchers…

Extreme heat in 2023 fuelled devastating wildfires in Greece SAKIS MITROLIDIS/AFP via Getty Images Temperatures over the past three years have been even higher than expected, provoking a debate among scientists. Almost everyone agrees that global warming has accelerated. But some researchers say it is speeding up even more than…

For years, scientists have been keeping a wary eye on the massive system of currents that carry water and nutrients across the ocean from Greenland to Antarctica. The Atlantic Meridional Overturning Circulation plays a large part in stabilizing the global climate, but it appears to have been weakening in recent…

Global warming has been increasing at a faster pace since about 2015, according to a new study from the Potsdam Institute for Climate Impact Research (PIK). By adjusting global temperature records to remove known natural influences, researchers were able to identify a statistically significant rise in the rate of warming…
