Human-induced climate change is already affecting many weather and climate extremes in every region across the globe. Scientists are also observing changes across the whole of Earth’s climate system; in the atmosphere, in the oceans, ice floes, and on land.
Many of these changes are unprecedented, and some of the shifts are in motion now, while some – such as continued sea level rise – are already ‘irreversible’ for centuries to millennia, ahead, the report warns.
But there is still time to limit climate change, IPCC experts say. Strong and sustained reductions in emissions of carbon dioxide (CO2) and other greenhouse gases, could quickly make air quality better, and in 20 to 30 years global temperatures could stabilise. More
