In a report this week, James Hansen, the famed former NASA scientist, argued that cutting pollution had already played a big role in causing global warming to accelerate. The reason is a little counterintuitive: For decades, humans have not only been emitting carbon dioxide and other greenhouse gases when they burn fossil fuels. They’ve also been spewing tiny sulfate particles into the air.
These particles spur the formation of more and brighter clouds, which help shield Earth from the sun. But as regulators have curbed sulfate pollution to protect people’s lungs, this cooling effect has diminished, exposing the planet to more of the full force of greenhouse warming.

Combustion engines, also known as internal combustion engines, have several problems including significant air pollution due to emissions like carbon monoxide, nitrogen oxides, and particulate matter, high fuel consumption, noise generation, vibration, dependence on fossil fuels, and potential for maintenance issues like oil leaks, worn bearings, and faulty spark plugs, all contributing to environmental concerns and potential health risks.
In a 2014 interview in the Washington Post of University of Miami climatologist Larry Kalkstein, who has published numerous research papers on weather-related mortality, weighed in on the matter: “Comparing apples to apples, which would be to evaluate acute or short-term responses to weather, I would always give the nod to heat-related deaths. However, if you are considering the seasonal differences in daily mortality, rather than just the “spikes” that we find with acute deaths, I can see why one can argue that winter (or cold-related) mortality is greater.” That was certainly the conclusion of a 2015 epidemiological study of deaths in 13 countries in The Lancet, which found that cold-related deaths in the U.S. were about a factor of fifteen higher than heat-related deaths. Cold deaths outnumbered heat deaths by a factor of twenty when averaged over all 13 countries studied. However, this study did not control for the seasonal cycle in death rates; deaths are always higher in winter, due to influenza and other non-weather-related factors.
The 2005 study, Heat Mortality Versus Cold Mortality: A Study of Conflicting Databases in the United States, advocated using gross mortality (or excess mortality, as shown in Figure 2 for the 1995 Chicago heat wave) as a way to arrive at a better estimate of heat-and cold-related deaths. They stressed that one must correct for the seasonal cycle in deaths before using this technique, to remove the influence of the winter influenza season and other non-weather-related factors. Interestingly, they found that major heat waves cause big spikes in the death rate, whereas major cold waves do not: “Severe heat waves often produce large "spikes" in mortality, especially during the 1995 heat wave across the Midwest. However, abnormally cold conditions have little effect on the standardized daily mortality. For example, February 1996, a cold period across much of the United States, produced no spikes in winter mortality levels.” Similarly, from the 2016 U.S. National Climate Assessment: “The relationship between mortality and an additional day of extreme heat is generally much larger than the relationship between mortality and an additional day of extreme cold.”

And don't let those who have an anti-EV agenda lie to you.
I don't know if Trump was lying or just honestly has his facts wrong, but either way, there is no EV mandate. The Biden administration DID tighten fuel-economy standards (though not as much as initially proposed) and the EPA did tighten tailpipe-emissions rules but there is no rule or law forcing automakers to build EVs or a certain percentage of EVs. Biden has set a goal of 50 percent EV sales by 2030, but that's a goal not a mandate.
Some might argue that the tighter rules will, in effect, force automakers to build more EVs in order to comply, but that would ignore that automakers can get there using other tech including hybrids. Automakers could also, if I understand the rules correctly, be in compliance simply by building more vehicles that have fuel-efficient internal-combustion powertrains -- you know, the kind of vehicles that have become scare as consumers flock to more-profitable crossovers and SUVs.
Even if the new rules do force automakers to alter their product mix and offerings to be in compliance, it is not a mandate that they build EVs.
I'd also add, taking off the fact-checker hat and putting on the analyst hat, that many American-built EVs are built in states that show heavy support for Donald Trump. Not only is Trump likely upsetting automakers, who need regulatory consistency since they plan models years in advance, but he could be upsetting his own constituents.
The Biden Administration dropped a new rule limiting tailpipe emissions from passenger vehicles yesterday, and you know what that means.
Yes, it's lying season!
I want to focus on one particular egregious lie. You will soon see arguments from certain anti-EV types that new rule is an EV mandate. It very much is not.
First, some background from the New York Times:
The rule increasingly limits the amount of pollution allowed from tailpipes over time so that, by 2032, more than half the new cars sold in the United States would most likely be zero-emissions vehicles in order for carmakers to meet the standards.
We can argue all day long about whether the rule is too stringent or not, or whether automakers will be able to achieve the administration's goals. But as the Times points out, the government is NOT forcing the fleet to become all electric:
The E.P.A. regulation is not a ban. It does not mandate the sales of electric vehicles, and gas-powered cars and trucks could still be sold. Rather, it requires carmakers to meet tough new average emissions limits across their entire product line. It’s up to the manufacturers to decide how to comply.
That hasn't stopped the American Fuel & Petrochemical Manufacturers lobbying arm from calling the rule "Biden's EPA car ban." This is where I credit the oft-beleaguered Times, which I have hit at here and there, for not pulling punches and calling that assertion false.
It's not a ban on cars or internal-combustion engine cars. It's just not. And don't let those who have an anti-EV agenda lie to you.
