The gorgeous days of a late April cold snap counter the dire warnings of climate change.
Brisk wind, sunshine and a perfect blue sky mask our abuse of the Earth.
Last spring, during the worst days of the pandemic's lockdown, the sky appeared even bluer, as emissions plunged.
That progress has been washed away as the economic recovery accelerates.
Emissions will increase 5 percent this year, eliminating 80 percent of last year's carbon reduction, according to a report by the International Energy Agency. During 2021, a total of 33 billion tons of carbon will be spewed into the Earth's fragile atmosphere.
As emissions again rise to alarming levels, President Joe Biden on Thursday will lead a virtual climate change summit of world leaders, with a pledge for the United States to reduce carbon emissions 50 percent by 2030.
Chinese President Xi Jinping will participate. Biden's energy adviser John Kerry recently reached an agreement with China for joint action on climate change, a plan predictably blasted by the Wall Street Journal editorial page.
Rising coal demand in Xi's China, along with other Asian countries, is a major cause of the resurgence in climate emissions. At the same time, China is stepping up renewable energy production.
Biden's summit demonstrates a return to American leadership of global climate change efforts. A return of GOP control of Congress and the presidency would shatter that progress.
