In the years ahead, sea level rise, more intense storm surge and jacked-up tropical storms will be visiting many of the world’s roughly 3,800 ports.…
No organism on Earth is known to live as long as the Great Basin bristlecone pine. The oldest documented tree, a well-hidden specimen nicknamed “Methuselah,”…
In 2013, the Intergovernmental Panel on Climate Change (IPCC) report (Assessment Report 5; AR5) concluded that Northern Hemisphere temperatures had reached levels unprecedented in at…
Almost a quarter of the world’s population are exposed to significant flood risks, according to new research published Tuesday, which warned those in poorer countries…
Unless urgent action is taken, emissions are expected to cause the planet to continue heating rapidly over the next few decades, prompting the global average…
Antarctic ice sheets are melting, the continent’s climate is changing, and the Southern Ocean is warming, becoming more acidic and losing oxygen. Locally, changing climates…
Sea level rise will force the abandonment of about 200,000 coastal properties in England within 30 years, new data suggests, as the climate crisis takes…
A world severely blighted by plastic pollution is on track to see the use of plastics nearly triple in less than four decades. Even with…
In their effort to provide decision makers with insight into the consequences of climate change, climate researchers are bringing order to the large number of…
Humanity is “at a crossroads” when it comes to managing drought and accelerating mitigation must be done “urgently, using every tool we can,” says a…
Coral reefs are rapidly declining due to local environmental degradation and global climate change. In particular, corals are vulnerable to ocean heating. Hotter oceans can…
Amazon rainforest becomes a savanna The 2.5 million square mile rainforest is so vast it creates its own rainfall and is home to 10% of…
The study examined four possible scenarios for future carbon emissions, and found increased risk of El Niño events in all four. This means El Niño…
Although Africa has contributed relatively little to the planet’s greenhouse gas emissions, the continent has suffered some of the world’s heaviest impacts of climate change.…
As required by the UK Climate Change Act 2008, the government has today submitted the Third Climate Change Risk Assessment (CCRA3) to Parliament. Professor Richard…
In 2009, an international team of researchers identified nine planetary boundaries that demarcate the remarkably stable state Earth has remained within for 10,000 years—since the…
A few days before Christmas, Super-typhoon Rai – known locally as Odette – ravaged the Philippines. Lost lives continue to climb two weeks on. Vast…
“We need drastic, radical emissions reductions, and on top of that we need some CDR,” said Glen Peters, research director at the Centre for International…
Today’s emission reduction pledges cover less than 20% of the gap that needs to be closed by 2030 to keep a 1.5 °C path within…
National net zero emission targets could, if fully implemented, reduce best estimates of projected global average temperature increase to 2.0–2.4 °C by 2100, bringing the Paris…
Global greenhouse gas emissions must peak in the next four years, coal and gas-fired power plants must close in the next decade and lifestyle and…
Rising sea levels and climate change are posing serious threats to the population and economy of several Asian coastal cities—Bangkok, Dhaka, Jakarta, Manila and Shanghai,…
The comprehensive assessment of climate science published on Monday, the sixth such report from the IPCC since 1988, has been eight years in the making. It represents the world’s…
Earth’s temperature is projected to hit 1.5˚C or 1.6˚C around 2030 in all five scenarios—a full decade earlier than a similar prediction the IPCC made…
If climate change continues at its current rate, more than 98% of emperor penguin colonies are expected to become quasi-extinct by the turn of the century.…
“We find that there is a substantial mismatch between likely warming rates and research coverage. 1.5 °C and 2 °C scenarios are substantially overrepresented. More…
“There is growing evidence we are getting close to or have already gone beyond tipping points associated with important parts of the Earth system” The…
Carbon emissions are set to hit an all-time high by 2023 as just two percent of pandemic recovery finance is being spent on clean energy. “Not…
The figures are based on projections of a population growth of about 4.5 billion over the same period, and a temperature rise of about 3.7˚C by 2100.
Chair of CCAG, Sir David King said: “I believe we have five years left to get on top of this global problem. We began talking seriously…
Species extinction, more widespread disease, unliveable heat, ecosystem collapse, cities menaced by rising seas—these and other devastating climate impacts are accelerating and bound to become…
“I cannot say that there was really any breakthrough in the consultations that took place here” said United Nations climate chief Patricia Espinosa.
“If we allow fossil fuel burning to continue to grow, our grandchildren may experience CO₂ levels that haven’t been seen on Earth for around 50 million years, a…
“Going to get worse.”
“There is no longer any realistic chance for an orderly transition.”
“While 63% of reefs are projected to continue to accrete by 2100 under the low-impact pathway, 94% will be eroding by 2050 under the worse-case scenario,” Dr…
