Climate Change
Why is
1.5°C
Important?
While there will still be serious climate impacts at 1.5°C, this is the level scientists say is associated with less devastating impacts than higher levels of global warming. Every fraction of additional warming beyond 1.5°C will bring worse impacts, threatening lives, livelihoods and economies.
What are the effects & Impact of climate change?
At 1.5°C, over 70% of coral reefs will die, but at 2°C, all reefs over 99% will be lost.
Insects, vital for pollination of crops and plants, are likely to lose half their habitat at 1.5°C but this becomes almost twice as likely at 2°C.
The Arctic Ocean being completely bare of sea ice in summer would be a once per century likelihood at 1.5°C but this leaps to a once a decade likelihood at 2°C.
Over 6 million people currently live in coastal areas vulnerable to sea-level rise at 1.5°C degrees, and at 2°C, this would affect 10 million more people by the end of this century.
Sea-level rise will be 100 centimetres higher at 2°C than at 1.5°C.
The frequency and intensity of droughts, storms and extreme weather events are increasingly likely above 1.5°C.

Atmospheric CO2 from AIRS 2002-2016
This time series shows global changes in the concentration and distribution of carbon dioxide since 2002 at an altitude range of 1.9 to 8 miles. The yellow-to-red regions indicate higher concentrations of CO2, while blue-to-green areas indicate lower concentrations, measured in parts per million.
