Climate change is man-made
There is little doubt that climate change is due to greenhouse gases (especially CO2) released into the atmosphere by human activity.
Levels of CO2 have increased steadily since mankind started burning fossil fuels in large quantities :
The average temperature rises are in line with what is predicted by scientists from what is known about the atmosphere.
Whilst we can never be absolutely certain about what is happening, scientist are over 90% certain that we are heading for a catastrophe. Who would board a train knowing that the risk of it crashing was over 90%?
