SUNLIGHT ON CLIMATE CHANGE explains in understandable terms the science of how both natural and human-caused global warming work. It describes how expensive and doubtful strategies, adopted by governments to comply with the goals of the Paris Agreement, have caused and will continue to cause increased human emissions of carbon dioxide, contribute to unhealthy air quality and significantly increase food costs for the very poor. It explores why declarations of a climate emergency are based on a political agenda, not scientific facts, and invites the reader to reconsider this belief system in the light of science. Carbon dioxide has physical limitations as a greenhouse gas; global warming began a prolonged pause in 1998. Choosing classical science over politicized pseudo-science is not denial, it is heresy.
