Iron is not commonly famous for its role as a micronutrient for tiny organisms dwelling in the cold waters of polar oceans.
There are those who say the climate has always changed, and that carbon dioxide levels have always fluctuated.
The summer of 2015-2016 was one of the hottest on record in Australia. But it has also been hot in the waters surrounding the nation: the hottest summer on record, in fact.
New research illustrates that reactions of people, plants and animals to the changing climate are a key factor in unravelling the complexities of global warming.
Global temperatures for February showed a disturbing and unprecedented upward spike. It was 1.35℃ warmer than the average February during the usual baseline period of 1951-1980, according to NASA data.
Much has been written about the challenge of achieving the targets set out in the Paris climate agreement, which calls for global warming to be held well below 2℃ and ideally within 1.5℃ of pre-industrial temperatures.
Global sea level rose faster in the 20th century than in any of the 27 previous centuries, a new analysis shows.
Antarctica and Greenland may be two of the most remote places on Earth but what happens in both these vast landscapes can significantly impact on human activity further afield.
New scientific studies provide a further warning of the increasing vulnerability of Antarctic glaciers to faster melting as temperatures rise in the Southern Ocean.
The North Atlantic is gulping down twice as much human-caused carbon and becoming increasingly acidic, intensifying alarm for marine creatures.
For billions of years, life on Earth remained relatively simple. Only single-celled organisms that could live with little or no oxygen were able to survive in the seas.
A pioneering fieldwork study of mountain heights and boulders in West Antarctica supports computer predictions that global sea levels could rise steeply by 2080.
Records from a sailing ship’s round-the-world research voyage almost 150 years ago provide further evidence that the Earth is continuing to warm unchecked.
New analysis reveals overwhelming odds on years of record global temperatures being caused by human impacts on the planet, rather than natural causes.
Scientists find evidence of vast “storage tanks” of water deep below the melting Greenland ice sheet that could have a major effect on sea level rise.
In the wake of a Missouri grand jury’s decision not to indict Darren Wilson, the police officer who shot and killed Michael Brown, it can be difficult to imagine a place where law enforcement and a racially diverse population work together productively in the United States.
For several years now climatologists have puzzled over an apparent conundrum: why is Antarctic sea ice continuing to expand, albeit at the relatively slow rate of about one to two percent per decade, while Arctic sea ice has been declining rapidly?
Reduced monsoon rainfall and increased river flow are two extremes that new research has linked to man-made impacts on climate caused by air pollution.
The exotic lionfish, already a long way from the reefs of its Indo-Pacific home, is heading further north up the US coast as global warming causes big changes to ocean habitats.
New scientific research confirms that global warming is melting increasingly larger areas of Arctic sea ice − and reducing its vital function of removing CO2 from the atmosphere.
Here’s an historical tidbit you may not be aware of. Between the years 1860 and 1940, as the number of Methodist ministers living in New England increased, so too did the amount of Cuban rum imported into Boston – and they both increased in an extremely similar way. Thus, Methodist ministers must have bought up lots of rum in that time period!
Scientists simulating changes in mountain glaciers over the last century and a half have established that rates of melting have increased greatly in recent years – and that humans are the main culprits.
Dire warnings of imminent human-induced climate disaster are constantly in the news but predictions of the end of the world have been made throughout history and have never yet come true.
The newly released National Climate Assessment spans 30 chapters with thousands of references on how climate change is impacting the U.S. The report took more than 300 scientists and 4 years to prepare, including addressing more than 4,000 comments from the public. The message of the report is that climate change is already happening across the country.
Parts of ancient Antarctica were as toasty as today’s California coast, say scientists who used a new method to measure past temperatures. The study focused on Antarctica during the Eocene epoch, 40 to 50 million years ago, a period with high concentrations of atmospheric CO2 and consequently a greenhouse climate.
If wealth and income weren’t already so concentrated in the hands of a few, the shameful “McCutcheon” decision by the five Republican appointees to the Supreme Court wouldn’t be as dangerous. But by taking “Citizen’s United” one step further and effectively eviscerating campaign finance laws, the Court has issued an invitation to oligarchy.
It’s being billed as “the biggest story of our time.” This weekend viewers of Showtime, the US cable channel, will be watching the first of an nine-part documentary series on climate change: some of the biggest names in Hollywood are involved.
Can the U.N. Intergovernmental Panel on Climate Change most recent report or a star-studded Showtime mini-series change the way people talk and think about climate change? Katharine Hayhoe urges her fellow climate scientists to ramp up their messaging game.
Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast section of the ice sheet is no longer stable. This means global sea levels may rise even faster than was previously anticipated.
Ice in the Arctic continues to retreat. It’s long been established that Arctic ice is on the retreat but it’s the pace of change that’s surprising scientists: latest studies show the region is at its warmest since 40,000 years.
