Arctic Report Card tracks region’s environmental changes

Persistent heat records have assaulted the fragile Arctic for each of the past five years—a record-long warming streak, said the 2018 Arctic Report Card, released by NOAA.
2019 may be the hottest year yet—here’s why

An El Niño event is very likely under way, amping up extreme weather already made worse by climate change and increasing the odds that 2019 will be the hottest year in recorded human history, scientists warn.
Humans may be reversing the climate clock, by 50 million years

Our future on Earth may also be our past. Researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it’s taken just two centuries.
Tackle climate or face financial crash, say world’s biggest investors

A group of more than 400 investors managing $32 trillion in assets issued a stark warning to governments at the UN climate summit, demanding urgent cuts in carbon emissions and the phasing out of all coal burning. Without these, the world faces a financial crash several times worse than the 2008 crisis.
The ‘great dying’: rapid warming caused largest extinction event ever, report says

Up to 96% of all marine species and more than two-thirds of terrestrial species perished 252m years ago. Rapid global warming caused the largest extinction event in the Earth’s history, which wiped out the vast majority of marine and terrestrial animals on the planet, scientists have found.
Greenland ice sheet melt ‘off the charts’ compared with past four centuries

Surface melting across Greenland’s mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research.
Uneven rates of sea level rise tied to climate change

The pattern of uneven sea level rise over the last quarter century has been driven in part by human-caused climate change, not just natural variability, according to a new study.
David Attenborough: collapse of civilisation is on the horizon

The collapse of civilisation and the natural world is on the horizon, Sir David Attenborough has told the UN climate change summit in Poland.
Nations must triple efforts to reach 2°C target, concludes annual review of global emissions

Global emissions are on the rise as national commitments to combat climate change come up short. But surging momentum from the private sector and untapped potential from innovation and green-financing offer pathways to bridge the emissions gap. Those findings along with a sweeping review of climate action and the latest measurements of global emissions were presented by authors of the 2018 Emissions Gap Report.
