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

The latest IPCC report makes it clear we can no longer stop the seas from rising, but we can still control how much and how fast sea levels change.

Australia may warm by 4℃ 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℃ warming is measured – and why there’s still reason to hope, and act, if Earth exceeds that limit.

Human activity is changing the Earth’s climate in ways “unprecedented” in thousands or hundreds of thousands of years, with some of the changes now inevitable and “irreversible”, climate scientists have warned.

Within the next two decades, temperatures are likely to rise by more than 1.5C above pre-industrial levels, breaching the ambition of the 2015 Paris climate agreement, and bringing widespread devastation and extreme weather.

As global temperatures rise, heatwaves, droughts, floods and other impacts will become more widespread, the sixth annual report says

• Major climate changes inevitable and irreversible - IPCC’s starkest warning yet

The first major assessment of its kind in seven years from the UN’s Intergovernmental Panel on Climate Change has found the globe’s ocean, lands and air temperatures are rising, and the human influence is “unequivocal”.

But what does the IPCC’s Sixth Assessment Report say about changes in Australia, and what can we expect for the future?

Intergovernmental Panel on Climate Change states every corner of the planet is already being affected and it could get far worse

• IPCC report’s verdict on climate crimes of humanity: guilty as hell
• Humans have caused ‘unprecedented’ and ‘irreversible’ change to climate, scientists warn

“​​It is unequivocal.” Those stark three words are the first in the Intergovernmental Panel on Climate Change’s new report. The climate crisis is unequivocally caused by human activities and is unequivocally affecting every corner of the planet’s land, air and sea already.

The report, produced by hundreds of the world’s top scientists and signed off by all the world’s governments, concludes that it could get far worse if the slim chance remaining to avert heating above 1.5C is not immediately grasped.
