Extreme Temperature Diary- Tuesday March 21st, 2023/ Main Topic: Do Americans Still Have a Problem with Celsius Measures for Climate Change?

The main purpose of this ongoing blog will be to track global extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉

Main Topic: Do Americans Still Have a Problem with Celsius Measures for Climate Change?

Dear Diary. This morning I received a newsletter from the New York Times suggesting that most Americans are having a problem understanding the urgency of the climate crisis simply because we continue to use the Fahrenheit system for measuring temperatures instead if Celsius like most of the rest of the world. Celsius increments are much smaller than those in the Fahrenheit system. For example, +1.5°C above preindustrial conditions appears to be a small number compared to +2.7°F above preindustrial conditions. From the newsletter, “By translating that figure to its Fahrenheit equivalent — 2.7 degrees — it can take on a clearer meaning. Katharine Hayhoe, a climate scientist, uses the analogy of a fever: Think about how much worse you feel when you run a fever of 101.3 degrees Fahrenheit, 2.7 degrees above normal. That fever is the equivalent of what the planet is facing.”

When American grade school children and novices hear “32 degrees” for example, they think cold Fahrenheit thoughts or the freezing point of water, not that of 32 degrees Celsius or 90 degrees Fahrenheit.

I do ask, are Americans so poorly educated that climate science has to be dumbed down such that all reports need to have Fahrenheit translations? Knowing what has happened here in this country as a meteorologist and now climatologist to our education system, I have to shake my head and reluctantly agree with Dr. Hayhoe.

Also, there is a problem here with willful ignorance, some politically motivated. People won’t think that there is a climate crisis until it directly affects them with flood, fire or wind damage. Most Americans live comfortably in air conditioning, so heat waves need to be very severe for them to wake up to our relatively new nightmare.

Here is that New York Times newsletter:

A small change to climate science could make a big difference for Americans.

The world’s top scientists released their latest report yesterday warning that the Earth is on pace for severe damage from climate change. But many Americans might have a hard time understanding the report because the analysis, like those before it, talks about temperatures exclusively in Celsius.

The U.S. is among just a few countries that still use Fahrenheit temperatures. And while Americans are a relatively small audience on a global scale, they are an important one for climate science: The U.S. has historically emitted more planet-warming greenhouse gases than any other country. Improving Americans’ understanding of the issue could be crucial to any push for changes.

Why does excluding Fahrenheit matter? Most Americans lack experiences from their own lives to make sense of scientists’ warnings that the Earth could warm by up to 1.5 degrees Celsius above acceptable levels. To them, it is a small, meaningless number.

By translating that figure to its Fahrenheit equivalent — 2.7 degrees — it can take on a clearer meaning. Katharine Hayhoe, a climate scientist, uses the analogy of a fever: Think about how much worse you feel when you run a fever of 101.3 degrees Fahrenheit, 2.7 degrees above normal. That fever is the equivalent of what the planet is facing.

Most Americans can grasp that analogy because it speaks to their own experiences. They can’t do that with Celsius. “It is absolutely essential to communicate in terms and language that people understand,” said Hayhoe, who is from Canada, which uses Celsius.

The exclusion of Fahrenheit in scientific reports is not the main obstacle to more action on climate change. Broader science denial and the world’s reliance on fossil fuels are much bigger barriers. But including Fahrenheit figures is a small change — a matter of plugging some numbers into a calculator — that could help drive more action.

Today’s newsletter will look at the new climate report and how close, or not, the world is to avoiding the worst consequences.

The new analysis, a synthesis of six previous reports by the United Nations’ climate group, presents a mixed picture of the world’s fight against climate change. Here are three takeaways:

1) The world is on track to surpass a significant level of warming. The world is likely to hit what scientists consider relatively safe levels of warming — 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial temperatures — by the early 2030s, the report warned. Countries could still take steps to prevent that, by slashing greenhouse gas emissions in half by 2030 and no longer adding carbon dioxide to the atmosphere by the 2050s. But the required measures are so extreme that they seem increasingly unlikely, many experts say.

2) On the current track, brace for more disasters. Continued warming will mean more catastrophic flooding, deadly heat waves, crop-destroying droughts and other extreme weather. Some of those effects are already visible. Last year, record-breaking heat waves hit much of the world, including the U.S. and Europe, and floods submerged a third of Pakistan.

3) The world has made some real progress. In the past, climate reports warned that warming could surpass four degrees Celsius (7.2 degrees Fahrenheit) by 2100. Today, the Earth is on a trajectory of around two to three degrees Celsius (3.6 to 5.4 degrees Fahrenheit), thanks to the uptake of cleaner energy and to projections that coal use will decline. That difference of a few degrees can, like a fever, prevent more catastrophic events. And as my colleague Somini Sengupta noted, pivoting away from fossil fuels is the fastest way to stop global warming.

Despite some progress, the world is still on track to face devastating outcomes from climate change. To prevent the worst, scientists are calling for a massive effort that will require the world’s most powerful and richest countries to work together.

Getting so much of the world onboard requires communicating the problem in a way everyone can understand. Excluding the temperature measure used by the U.S. and some other nations hinders that mission. Offering different versions of reports with Celsius and Fahrenheit could help address that issue, or scientists and news outlets could translate Celsius-focused reports to Fahrenheit in their own work.

Here are some “ET’s” recorded from around the planet the last couple of days, their consequences, and some extreme temperature outlooks, as well as any extreme precipitation reports:
