Southern Québec is warming twice as rapidly as the rest of the world due to the progressive loss of snow cover. An average annual warming of 3 C to 6 C is expected by the end of the century.
Every five years nations must evaluate their progress towards the goals of the Paris Agreement. But this “stocktake” lacks detail making it difficult to measure progress on climate action.

To reduce pressure on cities and the environment, drivers should face a charge that reflects the actual costs of clogged roads, air pollution, climate change, injury and death.
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.
With climate action more crucial than ever, the IPCC needs to communicate clearly and strongly to as many people as possible. So how is it going so far?
Some of the climate changes will be irreversible for millennia. But some can be slowed and even stopped if countries quickly reduce their greenhouse gas emissions, including from burning fossil fuels.
Water-related hazards are exceptionally destructive, and the impact of climate change on extreme water-related events is increasingly evident, a lead author of the new report warns.

New Zealand’s climate has been changing in line with global trends over the last century, warming by 1.1°C. But unless we curb emissions fast, we can brace for more extreme downpours and droughts.
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.
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.
