While the Scott Walker and Donald Trump administrations expunged discussion of human-caused climate change from agency websites, other governments, organizations and industries respected science and economics.

Our military invests heavily to mitigate the effects of climate change on its readiness.

Saudi Arabia, the world’s largest oil exporter, is plowing money into solar energy to diversify its economy and become recognized as a force for clean power. The Saudis see solar as a cheap and clean alternative to fossil fuels. At a few cents per kilowatt-hour, the Saudis will generate solar electricity at less cost than using fossil fuel. And the Saudi push for solar energy will provide work for much of its younger population.

Xcel Energy will build plants generating wind and solar electricity in Colorado for less than it would pay to maintain its older coal-burning power plants.

Savvy decision-makers are embracing clean renewables for sound economic reasons that also support job growth. But their actions also will limit the threats to our climate, and fewer pollutants mean less asthma and other respiratory ailments for our families.

Pricing fossil fuels at a cost reflecting their damage to our health would further accelerate this welcome transition to renewable energy sources.
