2024 marks the first time since record keeping began that all of the 10 hottest years have fallen within the most recent decade.

The world is warming despite natural fluctuations from the El Niño cycle.

An updated threat assessment warns of the consequences of a divided NATO and an absent U.S.

Scientists now fear that there is little more than five years left to prevent irreversible climate damage and stark changes to the Earth’s weather patterns from global carbon emissions, Minister for Climate Eamon Ryan has warned.

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

New research shows the company’s scientists were as “skillful” as independent experts in predicting how the burning of fossil fuels would warm the planet and bring about climate change.

An international team of scientists painstakingly gathered data from more than 50 years of seagoing scientific drilling missions to conduct a first-of-its-kind study of organic carbon that falls to the bottom of the ocean and gets drawn deep inside the planet.

New analysis says that particulate pollution is the greatest threat to human health in India.

Urgenda has become synonymous with a particular kind of lawsuit brought against a state for inaction on climate change. What impact it has had both in the Netherlands and internationally?

In 1972, a book changed the world. The Club of Rome commissioned a report that shifted how we see what humans are doing to the planet. Looking back five decades later, what happened next, what did we do and not do, what did we learn, and what happens now? In The Limits to Growth, a team from MIT studied the way humans were using the resources of the earth. Using sophisticated computer modelling, the researchers developed scenarios to map out possible paths for humanity, the global economy and the impact on the planet.

There is a 50:50 chance of the annual average global temperature temporarily reaching 1.5 °C above the pre-industrial level for at least one of the next five years – and the likelihood is increasing with time, according to a new climate update issued by the World Meteorological Organization (WMO).

Climate change is raising flood risks in neighborhoods across the U.S. much faster than many people realize. Over the next three decades, the cost of flood damage is on pace to rise 26% due to climate change alone, an analysis of our new flood risk maps shows.

The loss of its buttressing ice shelf could hasten the demise of the “Doomsday Glacier”

Study finds natural regrowth yields better results than human plantings and offers hope for climate recovery

Scientists have uncovered a fascinating new insight into what caused one of the most rapid and dramatic instances of climate change in the history of the Earth.

Increase means country will slip back from goal of cutting emissions by 40% from 1990 levels

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 behavioural changes will be needed to avoid climate breakdown, according to the leaked draft of a report from the world’s leading authority on climate science.

In the archive of the UK Centre for Ecology & Hydrology there is a typed note from the 1960s that planted the seed of an idea.

Plants should be flourishing in these ocean waters with plenty of nutrients and inorganic carbon in the form carbonic acid. It could be possible the phytoplankton are missing key nutrients such as ferric, but why should this be happening now?

The effects of ‘weird weather’ were already being felt in the 1960s, but scientists linking fossil fuels with climate change were dismissed as prophets of doom
