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 temperature rise is in line with what is predicted by scientists from what is known about the atmosphere.

Levels of CO2 have increasd since the burning of fossil fuels

Levels of CO2 have increased steadily since mankind started burning fossil fuels in large quantities [1]:


As the atmospheric CO2 has increased, so has the temperature

The average temperature rises are in line with what is predicted by scientists from what is known about the atmosphere.
