Scientists have been making projections of future global warming using climate models of increasing complexity for the past four decades

October 5, 2017 — These models, driven by atmospheric physics and biogeochemistry, play an important role in our understanding of the Earth’s climate and how it will likely change in the future. Continue reading Analysis: How well have climate models projected global warming

It takes just 4 years to detect human warming of the oceans

Our new paper illustrates the rapid, consistent warming of Earth’s oceans

September 21, 2017 — We’ve known for decades that the Earth is warming, but a key question is, how fast? Another key question is whether the warming is primarily caused by human activities. If we Continue reading It takes just 4 years to detect human warming of the oceans

‘Bigger and stronger’ storms on the horizon – experts

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. Continue reading ‘Bigger and stronger’ storms on the horizon – experts

In an era of unwelcome climate records Hurricane Harvey won’t be the last

From the US to India and China, human impact on the climate is likely to have made droughts and storms more severe – and the trend is only set to continue

August 30, 2017 — The 17tn US gallons of rain (roughly 26m Olympic swimming pools) dumped on Texas by Hurricane Harvey has set a new high for a tropical system in the US, but it is unlikely to Continue reading In an era of unwelcome climate records Hurricane Harvey won’t be the last

World’s northernmost coral reef in Japan bleached

BLEACHED. This combination of handout pictures released by Japan’s National Institute for Environmental Studies and created on July 18, 2017, shows coral reefs (L) in Toyotama, off the coast of Tsushima island taken in January 2016 before bleaching and the same coral reefs (R) in December 2017, after bleaching due to high water temperature. National Institute for Environmental Studies/AFP

About 30% of the coral reef off the coast of Tsushima island in Japan, which lies in the temperate zone, suffered bleaching, researchers say

TOKYO, Japan (Jul. 18, 2017) — Bleaching has damaged the world’s northernmost coral reef in Japan, a researcher said Tuesday, July 18, the latest example of a global phenomenon scientists have attributed to high ocean temperatures. Continue reading World’s northernmost coral reef in Japan bleached

New study confirms the oceans are warming rapidly

Although there’s some uncertainty in the distribution among Earth’s ocean basins, there’s no question that the ocean is heating rapidly

June 27, 2017 — As humans put ever more heat-trapping gases into the atmosphere, the Earth heats up. These are the basics of global warming. But where does the heat go? How much extra heat is Continue reading New study confirms the oceans are warming rapidly

Global warming scientists learn lessons from the pause that never was

New study finds there never was an unexpected lull in climate change but says the science community needs to communicate better

May 4, 2017 — People don’t talk about how global warming has stopped, paused or slowed down all that much any more – three consecutive hottest years on record will tend to do that to a flaky meme. Continue reading Global warming scientists learn lessons from the pause that never was

Half of world’s ocean to face multiple ‘climate stressors’ by 2030, study warns

Climate change is altering the world’s watery expanses in a number of ways, with serious knock-on effects for the ocean’s plants and animals, according to new research.

March 7, 2017 — The study finds that with just 15 more years of current emissions, over half of the world’s ocean will be exposed to more than one source of stress, affecting everything from the tiniest plants to the mightiest whales. By 2050, that figure rises to around 86% of the ocean, say the authors. Continue reading Half of world’s ocean to face multiple ‘climate stressors’ by 2030, study warns

Arctic sea ice could disappear even if world achieves climate target

Goal of limiting rise in average global temperatures to below 2°C may not prevent ice-free Arctic, scientists warn

March 6, 2017 — Arctic sea ice could vanish in summers this century even if governments achieve a core target for limiting global warming set by almost 200 countries, scientists have said. Continue reading Arctic sea ice could disappear even if world achieves climate target

An independent report says the ‘unprecedented’ bleaching and coral die-off in 2016 was ‘a game changer’

SYDNEY, Australia (Feb. 26, 2017) — Australia’s plan to rescue the beleaguered Great Barrier Reef has been set back at least two decades after the fragile ecosystem suffered its worst-ever bleaching last year, experts said Friday, February 24.
