Clean air legislation reinstated the global warming suppressed by industrial pollution

A fascinating post at WUWT:

The story so far;

  1. The earth was warming naturally after the Little Ice Age (1350 – 1850).
  2. Along came the industrial revolution. Dust and aerosol pollution covered large parts of the earth and blocked out the Sun. This caused a gradually increasing suppression of the global warming that was occurring as the industrialisation of the world proceeded. This suppression reached a maximum during the 1970’s.
  3. Then came clean air legislation around the world, cleaned up the atmosphere and the Earth basked in the sunlight again.

Global warming was rediscovered.

And now as the LIA temperature recovery is coming to a natural end, global temperatures will decrease again.

Well it is a settled science after all.

Shocker: Global warming may simply be an artifact of clean air laws
