Limiting global warming to 1.5°C and avoiding the worst effects of climate change will take more than eliminating greenhouse gas emissions. The world will also need to capture and store a lot of carbon dioxide (CO₂) from the atmosphere.

Even with all humanity’s carbon emissions to date, there’s a lot less carbon dioxide in Earth’s atmosphere than Venus, and Earth is further away from the Sun.

Fossil fuels and agriculture are driving a dangerous acceleration in methane emissions, at a rate consistent with a 3-4℃ rise in global temperatures this century.

Images of colossal chunks of ice plunging into the sea accompany almost every news story about climate change. It can often make the problem seem remote, as if the effects of rising global temperatures are playing out elsewhere.

Mass extinctions are times in Earth’s past when large proportions of life suddenly and catastrophically died. These have occurred periodically over the past 550 million years.

Australia is home to around 2% of the world’s mangrove forests and is the fifth most mangrove-forested country on Earth. Mangroves play a crucial role in the ecosystem thanks to the dizzying array of plants, animals and birds they feed, house and protect.

Each September, scientists like me look out for the point when the Arctic’s meagre summer fizzles out and sea ice begins to grow once more.

The planet had already warmed by around 1.2℃ since pre-industrial times when the World Health Organization officially declared a pandemic on March 11 2020.

High fire risk days have been common this year as the 2020 wildfire season shatters records across the West.

Improved “weather forecasts” for oceans hold hope for reducing devastation to fisheries and ecosystems around the world

This video is a crash course in climate misinformation, summarizing the key arguments used to cast doubt on the reality of climate change and delay climate action.

It was a grim record. On June 20 2020, the mercury reached 38°C in Verkhoyansk, Siberia – the hottest it’s ever been in the Arctic in recorded history.

Peatlands cover just a few percent of the global land area but they store almost one-quarter of all soil carbon and so play a crucial role in regulating the climate.

We know the climate changes as greenhouse gas concentrations rise, but the exact amount of expected warming remains uncertain.

Global emissions of methane have reached the highest levels on record, research shows.

The last time global carbon dioxide levels were consistently at or above 400 parts per million (ppm) was around four million years ago during a geological period known as the Pliocene Era (between 5.3 million and 2.6 million years ago).

Jules Verne sent his fictional submarine, the Nautilus, to the South Pole through a hidden ocean beneath a thick ice cap.

A ruling by the UK Supreme Court could have huge implications for British companies accused of environmental damage overseas.

Ice shelves, massive floating bodies of ice, are well-known for their buffering effect on land-based ice sheets as they slow their flow towards the sea.

How can I reduce my carbon footprint? As sustainability researchers, we regularly field this question, from friends and family but also journalists.

When I studied climate in my university geography course in the 1960s, I am sure we were told that the Earth was cooling.

Everyone is going on about reducing our carbon footprint, zero emissions, planting sustainable crops for biodiesel etc.

Humans are emitting CO₂ and other greenhouse gases into the atmosphere. As these gases build up they trap extra heat and make the climate warmer. But how much warmer?
