Greenland’s conditions were once similar to those of a greenhouse. Volcanoes swelled the land, constricted seaways and gigatonnes of greenhouse gases were released into the atmosphere.
What might sound like small changes – temperatures another tenth of a degree warmer, sea level a few centimeters higher – have big consequences for the world around us.
Academic research can shed light on crucial questions about what life on Earth will be like under the most plausible emissions scenarios. And a warning: the answers are confronting.
IPCC reports are often used as legal tool for bringing the powerful to account. And the more Australia’s governments and businesses lag on climate change, the more litigation we’re likely to see.
The IPCC report has laid out some alarming sea level projections for the future. But the relationship between sea level rise and real-world risk is complex.
From the high Yukon to the mountains of Central Asia, melting ice exposes fragile ancient artifacts that tell the story of the past – and provide hints about how to respond to a changing climate.
Australia may warm by 4°C or more this century, the IPCC has found. As these IPCC authors explain, there is no going back from some changes in the climate system.
IPCC authors go beyond the headlines to explain how 1.5°C warming is measured – and why there’s still reason to hope, and act, if Earth exceeds that limit.
The Intergovernmental Panel on Climate Change has released its long-awaited report. From accelerating emissions to intensifying disasters to rising sea levels, its authors lay out the new findings.
An article in the eminent US magazine Science has triggered debate over whether scientists should use climate models. Here’s what you should know about climate models ahead of today’s IPCC report.
234 scientists from 66 countries reviewed over 14,000 research papers. It was gruelling and it was worth it: the report is the most important global assessment of climate change science yet.
