As the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn’t survive.

NASA and NOAA jointly reported that 2016 was the warmest year on record. That’s no surprise, as the first six months of the year were all exceptionally warm.

For the Arctic, like the globe as a whole, 2016 has been exceptionally warm. For much of the year, Arctic temperatures have been much higher than normal, and sea ice concentrations have been at record low levels.

For a period about a million years ago Greenland wasn’t covered in ice. Researchers say the discovery suggests it’s possible the ice sheet could go away again.

You probably don’t think clams are the most exciting animals on the planet. But anyone who dismisses these marine bivalve molluscs surely cannot be aware of just how important they actually are. Without knowing it, they have taught us so much about the world we live in – and how it used to be.

2016 is set to be the world’s hottest year on record. According to the World Meteorological Organization’s preliminary statement on the global climate for 2016

The bulk of methane emissions in the United States can be traced to a small number of “super-emitting” natural gas wells.

NOAA’s National Centers for Environmental Information (and several other institutions) reported April 2016 to be the warmest April on record for the planet. All of the previous twelve months now hold the “Warmest [INSERT MONTH HERE] on Record” title. That’s twelve months in a row, and that’s never happened.

2016 continues to be a momentous year for Australia’s climate, on track to be the new hottest year on record.

Senior military figures in the US warn of national and international security threats posed by the impacts of climate change.

New research confirms that increased greenhouse gas levels ? rather than solar radiation impacts ? are the key factor in global climate change.

Claims that the “the science isn’t settled” with regard to climate change are symptomatic of a large body of ignorance about how science works.

In the early days of the Industrial Revolution, no one would have thought that their burning of fossil fuels would have an almost immediate effect on the climate.

The perennial question of how clouds affect the Earth’s climate takes another twist, with one study expecting cooling and another the opposite.

With the help of satellite data, scientists have shown that low-level cloud cover in the tropics thins out as Earth warms. Because this cloud cover has a cooling effect on the climate, the two-degree warming target set by the Paris Agreement may arrive sooner than predicted.

The United Nations climate change conference held last year in Paris had the aim of tackling future climate change. After the deadlocks and weak measures that arose at previous meetings, such as Copenhagen in 2009, the Paris summit was different.

The State of the Climate in 2015 report, led by the US National Oceanic and Atmospheric Administration, was released. Unfortunately, it paints a grim picture of the world’s climate last year.

After warming for nearly 50 years the Antarctic peninsula has begun cooling, though probably not for long, UK scientists say.

The dip in atmospheric carbon dioxide levels during the Little Ice Age wasn’t caused by New World pioneers cutting a swathe through native American agriculture, as had been previously thought.

New mapping of one of the most remote areas in Antarctica has revealed regions deep within Earth’s largest ice sheet that are particularly prone to rapid melting.

Experts say the results of a study of ancient zooplankton fossils offer a warning about mass extinction events: There’s a tipping point, at which dramatic declines in populations begin.

Think of an Australian landscape and you’re unlikely to picture snow-capped mountains or alpine meadows. But that’s what you’ll find atop the peaks of the country’s southeastern corner.
