Scientific evidence for warming of the climate system is unequivocal.' — Intergovernmental Panel on Climate Change
Our actions have consequences. Climate change is happening. We have to take responsibility. The maths inside provides the facts needed to wake us up.
Current CO2 concentrations are more than 417 parts per million (ppm), compared to the pre-industrial levels of 278 ppm.
Global surface temperatures are now 1.07°C warmer than they were between 1850–1900.
Warmer air holds more water vapour. For each degree of warming, the air's capacity for water vapour goes up by about 7%. An atmosphere with more moisture can produce more intense precipitation events, which is exactly what has been observed.
68% of all extreme weather events studied in the last 20 years were influenced by human-caused climate change. Heatwaves account for 43%, droughts make up 17% and heavy rainfall or floods account for 16%.
The number of floods and heavy rains has quadrupled since 1980 and doubled since 2004. Extreme temperatures, droughts and wildfires have also more than doubled in the last 40 years.
Let's fix it.
7 ways to help: Speak up, power your home with renewable energy, invest in energy-efficient appliances, reduce water waste, actually eat the food you buy, make less of it meat, pull the plug(s).
Let's rain it in.
