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?
The report projects an increase in mean temperatures and hot extremes across the continent. Worryingly the rate of temperature increase across the continent exceeds the global average.
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.
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.
