January 18, 2018 — Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study which, if correct, voids worst-case UN climate change predictions.

January 17, 2018 — Sea grasses are part of a team of coastal vegetation, including mangroves and salt marshes, that store up to 100 times more carbon than tropical forests at 12 times the speed. Vast prairies of sea grasses stretch for kilometers along the seafloor, storing enough carbon to rival the world’s forests.

January 17, 2018 — The World Economic Forum delivered a strong warning about Donald Trump’s go-it-alone approach to tackling climate change as it highlighted the growing threat of environmental collapse in its annual assessment of the risks facing the international community.

January 16, 2018 — Just over 250 million years ago, the planet suffered what may be described as its greatest holocaust: ninety-six percent of marine genera (plural of genus) and seventy percent of

WASHINGTON DC, USA (Jan. 10, 2018) — US President Donald Trump said on Wednesday, January 10, that the United States could “conceivably” return to the Paris climate accord, although he stopped short of signaling any move in that direction.

January 10, 2018 — The El Niño-Southern Oscillation (ENSO) cycle is a periodic change in the ocean-atmosphere system of the tropical Pacific Ocean but which has knock-on effects on weather around
the world. In an article recently published in Reviews in Geophysics, Santoso et al.  examined the 2015-2016 El Niño event which was particularly extreme. The editor asked one of the authors to explain the characteristics of that El Niño and what scientists learned from it.

January 10, 2018 — Germany’s reputation as a green leader is slipping, after reports this week the putative government will give up on meeting its 2020 emissions target.

One scientist hopes to understand the future of our forests by suspending a vast fog-catching mesh in the Peruvian jungle
January 5, 2018 — What will happen if climate change pushes clouds higher into the sky, as models predict? One ecosystem that will be seriously affected will be cloud forests – tropical jungles persistently bathed in fog.

January 4, 2018 — Ocean dead zones with zero oxygen have quadrupled in size since 1950, scientists have warned, while the number of very low oxygen sites near coasts have multiplied tenfold.

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.
