As we collectively reel from the changes wrought by the current pandemic, people are being drawn by analogy to climate issues – but analogies can be tricky and often distort as much as they illuminate. <\/p>\n\n\n\n

For instance, in the Boston Globe, Jeff Jacoby’s commentary<\/a> was not particularly insightful and misquoted Mike Mann pretty egregiously. Mike’s response<\/a> is good:<\/p>\n\n\n\n

I am relieved to see policy makers treating the coronavirus threat with the urgency it deserves. They need to do the same when it comes to an even greater underlying threat: human-caused climate change.<\/p>

In a recent column (\u201cI\u2019m skeptical about climate alarmism, but I take coronavirus fears seriously,\u201d<\/a> Ideas, March 15), Jeff Jacoby sought to reconcile his longstanding rejection of the wisdom of scientific expertise when it comes to climate with his embrace of such expertise when it comes to the coronavirus.<\/p>

In so doing, Jacoby took my words out of context, mischaracterizing my criticisms of those who overstate the climate threat \u201cin a way that presents the problem<\/a> as unsolvable, and feeds a sense of doom, inevitability, and hopelessness.\u201d<\/p>

As I have pointed out in past commentaries,<\/a> the truth is bad enough when it comes to the devastating impacts of climate change, which include unprecedented floods, heat waves, drought, and wildfires that are now unfolding around the world, including the United States<\/a> and Australia,<\/a> where I am on sabbatical.<\/p>

The evidence is clear that climate change is a serious challenge we must tackle now. There\u2019s no need to exaggerate it, particularly when it feeds a paralyzing narrative of doom and hopelessness.<\/p>

There is still time to avoid the worst outcomes, if we act boldly now, not out of fear, but out of confidence that the future is still largely in our hands. That sentiment hardly supports Jacoby\u2019s narrative of climate change as an overblown problem or one that lacks urgency.<\/p>

While we have only days to flatten the curve of the coronavirus, we\u2019ve had years to flatten the curve of CO2 emissions. Unfortunately, thanks in part to people like Jacoby, we\u2019re still currently on the climate pandemic path.<\/p>

Direct connections<\/strong><\/p>\n\n\n\n

There are some direct connections<\/a> too. The lockdowns and travel restrictions are having a material effect on emissions of short-lived air pollutants (like NOx, SO2 etc.), water discharges and carbon dioxide as well. The impacts on air<\/a> and water quality <\/a>are already being seen – perhaps allowing people to reset their shifted baselines for what clean air and water are like. <\/p>\n\n\n\n
