A curious online row over this summer's heatwaves points to a wider - and worrying - shift in climate science.

The loss of Antarctica’s doomsday glacier would transform our planet. Now scientists are revealing the secrets of this remotest of places, and asking the question: is its demise inevitable?

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

Do we really want to play dice with our planet?

Sea-level rise in conjunction with storm surge and tidal variations leads to extreme sea levels that threaten coastal systems. Here the authors use tide-gauge data and models to quantify how anthropog...

Temperatures above 15C ‘very strange’ say scientists, as snow melts and rain falls on glaciers in usually frozen region

Swampy mangrove forests are staging a surprise comeback - which is good news for coastal communities and the climate.

The US, Russia, Iran and Saudi Arabia – some of the highest oil-producing nations and major greenhouse gas emitters – opposed the measure

The US and other governments derailed an agreement on a global environment study, its co-chair says.

Scientists say ‘shocking’ discovery shows rapid cuts in carbon emissions are needed to avoid catastrophic fallout

Observations reveal that Arctic sea ice extent at the end of summer has halved, since satellite records began in the late 1970s.

How long tubes of mud - drilled out of the Antarctic seafloor - could reveal how the frozen continent is changing.

Study suggests the underwater valleys have a major impact on ice loss and ocean circulation

Worst-case scenario of 4.3C of warming could result in fiftyfold rise in heat-related deaths, researchers say

The cuts are a potentially fatal blow to the National Climate Assessment that Congress mandated to ensure the government understands the threats posed by rising temperatures.

A federal cost-cutting initiative may shut down the National Oceanic and Atmospheric Administration (NOAA) office that manages Hawaii’s Mauna Loa Observatory, a critical site for tracking atmospheric ...

The lab is connected to the Mauna Loa Observatory, where scientists gather data to produce the Keeling Curve, a chart on the daily status of atmospheric carbon dioxide concentrations.

Melting Antarctic ice is releasing cold, fresh water into the ocean, which is projected to cause the slowdown
