Touching on evidence of climate change
Global surface temperatures for five datasets
Adjusted to remove variation due to:• El Niño/La Niña• Volcanic particulates• Solar irradiance

Peer-reviewed science overwhelmingly indicates that:
Climate is changing globally This change is primarily (but not
exclusively) due to greenhouse gases, especially CO2
Frost is more likely on…
