Climate scientists have said the sun and moon influence the Earth’s climate, but not enough to contribute to the large-scale climate changes of the last several decades.
PolitiFact has rated False similar statements that minimize human activity’s role in climate change.
NASA and the Environmental Protection Agency determined that humans began to significantly impact the Earth’s climate during the Industrial Revolution, when manufacturing and burning fossil fuels led to the release of large amounts of greenhouse gases such as carbon dioxide into the atmosphere.
About 200 scientific organizations have concluded that human activity drives climate change. 
Corbyn, brother of British politician Jeremy Corbyn, received a degree in astrophysics in 1981. He launc …
