Researchers examined how warming temperatures and shifting precipitation patterns are affecting conifer forests, finding measurable impacts on tree growth and physiological function. The changes appear to be reducing the ability of these forests to absorb and store atmospheric carbon as effectively as before.
The EU's climate service confirmed that August matched July 2023 as the hottest month ever measured, with global temperatures averaging 1.65C above pre-industrial levels. Scientists attribute the spike to a combination of long-term climate change and an intensifying El Nino pattern in the Pacific. The month also closed out western Europe's hottest summer on record, exceeding the deadly heat wave of 2003.
Researchers analyzing two skeletons unearthed in Indonesia found heavy tooth wear and traces of arecoline, a psychoactive compound found in betel nuts. One skeleton dates back 16,000 to 25,000 years, suggesting the individuals regularly chewed or sucked on betel nuts long before the practice became widespread. The findings, published in Science Advances, push back the timeline for humanity's earliest documented drug habits.
The EU's Copernicus climate agency reported that August tied with July 2023 as the hottest month ever measured globally, following a summer that also produced the second-hottest June and July on record. NOAA separately confirmed this was the hottest US summer, surpassing the Dust Bowl era, while global average temperatures ran 1.65°C above preindustrial levels.
Copernicus reported that August 2023 statistically tied July 2023 as the hottest month ever measured, with global average temperatures reaching 16.96 degrees Celsius. Scientists attribute the extreme heat to a combination of long-term human-caused climate change and a strong El Nino weather pattern, noting the reading was 1.65 degrees Celsius above pre-industrial levels.
A recent earthquake on Norway's Jan Mayen Island triggered a rock slide, an event researchers point to as evidence that Arctic terrain is becoming more unstable. Scientists link the growing frequency and severity of such incidents to climate change, which is altering the physical conditions of the region's landscape.
A recent catastrophic flood event in Nepal illustrates how multiple climate-related hazards can combine to produce disasters far more severe than any single risk factor would suggest. Nature's commentary uses the event to argue that scientists and policymakers have been underestimating the danger posed by such compound risks.
A new UN Environment Programme report titled 'Limiting Overshoot' concludes that surpassing 1.5 degrees Celsius of warming above pre-industrial levels is now unavoidable. The paper notes current warming is near 1.4 degrees, but even with all existing climate pledges fulfilled, temperatures would still hit at least 1.8 degrees, while current trends point toward 2.6 degrees by 2100.
A new United Nations report concludes that global temperatures will almost certainly exceed the 1.5°C threshold set under the Paris Agreement within just a few years. Climate scientists broadly agree the milestone is now unavoidable, though some worry the report fails to offer clear guidance on next steps.
A new United Nations report finds that global warming is on track to exceed the 1.5°C threshold established by the Paris Agreement much sooner than previously expected, potentially within just a few years. The finding undercuts the most optimistic projections for limiting climate change that policymakers have relied on for years.
A new United Nations Environment Programme report concludes that Earth will soon surpass the 1.5 Celsius warming threshold set by the 2015 Paris agreement, largely due to continued fossil fuel emissions. Rather than treating this as unavoidable defeat, UN officials and scientists propose a strategy to temporarily exceed the limit before working to bring temperatures back down through ending fossil fuel use and deploying carbon removal technology.
Prediction market Kalshi has teamed up with The Weather Channel to verify outcomes of trades tied to weather events, including bets on record temperatures and extreme conditions. The partnership aims to add credibility to Kalshi's weather markets by using an established meteorological source for settling wagers.
