January 18, 2018 — New studies warn that global warming is not good news for aquatic life, putting at risk the creatures both of the seas and of inland waterways.

It was part of the fourth Evolution sale at Summers Place Auctions on Tuesday, 22nd November 2016 and the hammer went down at £280,000.

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

December 5, 2017 — The world’s oceans are under the greatest threat in history, according to Sir David Attenborough. The seas are a vital part of the global ecosystem, leaving the future of all life on Earth dependent on humanity’s actions, he says.

November 7, 2017 — The combination of climate change and overfishing is causing a population explosion in jellyfish. Since there are fewer fish to eat them, they appear off the British coast in vast

BONN, Germany (Nov. 6, 2017) — 2017 is on track to be the hottest year on record except for two warmed by El Niño phenomena, the UN’s World Meteorological Organization said Monday, November 6.

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.

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.

November 3, 2017 —What do Jellyfish teach us about climate change?
A lot. At least that’s what I learned after reading a very recent paper out in the journal Global Climate Change. The article, “Ocean acidification alters zooplankton communities and increases top-

August 30, 2017 — A dramatic period of global warming 56 million years ago that saw temperatures climb by up to five degrees and triggered extinctions of marine organisms was down to volcanic

August 1, 2017 — Coincidence doesn’t prove causality, as they say, but when the same two things happen together over and over again through the vast span of geological time, there must be a causal link.

July 25, 2017 — Extreme El Niño events that can cause crippling drought in Australia are likely to be far more frequent even if the world pulls off mission improbable and limits global warming to 1.5°C.
