Data shows the year was also one of the hottest three ever recorded, with scientists warning that the ‘climate tide is rising fast’

January 18, 2018 — 2017 was the hottest year since global records began that was not given an additional boost by the natural climate cycle El Niño, according to new data. Even without an El Niño, the year was still exceptionally hot, being one of the top three ever recorded. Continue reading 2017 was the hottest year on record without El Niño boost

Mass coral reef bleaching events have become five times more common worldwide over the past 40 years, new research finds, with climate change playing a significant role in the rise

January 4, 2018 — The scale of bleaching has been rising steadily in the last four decades, a study author tells Carbon Brief, with the global proportion of coral being hit by bleaching per year rising from 8% in the 1980s to 31% in 2016. Continue reading Severe coral reef bleaching now ‘five times more frequent’ than 40 years ago

The popularity of LED lights is driving an increase in light pollution worldwide, with dire consequences for human and animal health

MIAMI, USA (Nov. 23, 2017) — They were supposed to bring about an energy revolution – but the popularity of LED lights is driving an increase in light pollution worldwide, with dire consequences for human and animal health, researchers said Wednesday, November 22.

Scientists and policy experts say the White House released the report, which differs from the administration’s stance, without political tampering to avoid potential further controversy

November 6, 2017 — Although the Trump administration is busily rolling back Obama era climate policies, it also allowed the release last Friday of a major report that runs counter to the Continue reading Experts Ponder Why Administration Released Tough Climate Report

How Will Climate Change Affect the United States in Decades to Come

A satellite image of an atmospheric river over the northeastern Pacific on 20 February 2017, which helped California and the American West emerge from a 5-year drought. Atmospheric rivers—relatively long, narrow regions in the atmosphere—transport most of the water vapor outside of the tropics. When a large atmospheric river makes landfall, extreme precipitation—sometimes double the amount of rain that fell in the preceding 5 months—and flooding can result. The frequency and intensity of atmospheric rivers and droughts are just two realms explored in a new report that focuses on the effects of climate change across the United States.

A new U.S. government report shows that climate is changing and that human activities will lead to many more changes. These changes will affect sea levels, drought frequency, severe precipitation, and more

November 3, 2017 — Today scientists released a new report that details how climate change is affecting weather and climate across the United States and how future changes in climate could play out across the country. Continue reading How Will Climate Change Affect the United States in Decades to Come

More coral bleaching feared for Great Barrier Reef in coming months

The next event, if it occurs, may not be as damaging as the previous two, but could ruin the chances of coral recovery

November 3, 2017 — The Great Barrier Reef could face more bleaching in the coming months, following unprecedented mass bleaching events in 2016 and 2017, which are believed to have killed half the coral. Continue reading More coral bleaching feared for Great Barrier Reef in coming months

Scientists find that climate change has helped push first frosts later across the country

October 29, 2017 — The length of the US winter is shortening, with the first frost of the year arriving more than one later than it did 100 years ago, according to more than a century of measurements from weather stations nationwide. Continue reading US winter has shrunk by more than one month in 100 years

Despite a ‘rapid succession of disaster events’, the agency tracking changes in climate faces severe budget cuts under Donald Trump

September 3, 2017 — Even before Hurricane Harvey began to form, out in the north Atlantic, federal climate experts signalled that 2017 was going to be a bad year for weather and climate catastrophes in Continue reading Hurricane Harvey is a billion-dollar disaster – America’s 10th in 2017

Here are some answers to questions about the link between climate change and tropical storms, known variously around the world as cyclones, hurricanes, and typhoons

PARIS, France (Aug. 30, 2017) — Scientists say the devastating intensity of hurricanes such as Harvey is consistent with global warming trends – rising seas, warming oceans, hotter air – and warn of “bigger and stronger” storms to come.
