From The Deseret News in Utah:
By Cash Mendenhall
On July 17, Salt Lake City met the record for the highest summer temperature in recorded history, and by the time you read this that record may very well be broken.
We’re heading into the depth of a scorching summer with a worrying lack of clarity: Today, 99% of Utah is under either extreme or severe drought levels, with eight of the last 10 years being classified as drought years. We’ve become so desensitized to statistics like these in Utah and the West that heat waves and droughts barely register as policy issues, slipping under the radar of a rapidly metastasizing climate disaster. Eastern Utah has reported a temperature change over the last century triple that of the global temperature increase.
As a high school student, my generation is facing a steep collapse in livability.
It’s hot these days, it’s unusually hot, even dangerously hot, in a lot of places a lot of the time. While America has been hit hard this summer, it seems that Europe has been hit even harder. Naturally, this causes a lot of people to speculate, or to outright declare, or to outright deny, that the frequency and severity of heat waves has been increased by man-made climate change, also known as “global warming.”
I decided to study a single location in Europe, the daily high temperature in a small region near the town of Beaune, France, known for centuries as an outstanding wine-making region.
I retrieved data from the ERA5 reanalysis, and for each year I isolated the data for summer, which is defined as the months of June, July, and August. Then I computed each year’s summer average temperature, giving this:
Cliff Mass shows a graph, taken from the Seattle Times, of the hottest temperature each July from 1945 through 2022 at Seattle/Tacoma airport (SEATAC). He then says “… and there is very little upward trend! How could this be?”
Then he goes further:
Just to check on the Seattle Times… I did the same thing for July and August over the past 50 years, plotting the warmest observed temperature at both SeaTac and Pasco (see below).
Hardly any change in the extreme high temperatures each year at either site. No long-term trend….and you would expect a trend if global warming was important for the extreme heat waves!
Unfortunately for Cliff Mass, the data contradict him.
The heatwave which invaded England recently was no ordinary one.
At numerous locations the temperature exceeded 40°C (104°F) which, as far as we know, has never before happened in the British Isles. England definitely isn’t prepared for such temperatures, as Melissa Harrison makes abundantly clear in the Washington Post; an airport closed when the runway deformed in the heat, railway tracks buckled, the London fire department got so many calls it was their busiest day since world war II. The U.K. Meteorological Office advised people (especially the young, the old, and the ill) to go nowhere and do nothing but stay hydrated.
Not an ordinary heat wave.
Since the subject came up …
There are certain claims (some false) about the correlation (or not) between CO2 in the atmosphere and global temperature. Several folks have pointed out that we shouldn’t really be looking at the correlation between temperature and CO2, but between temperature and CO2 forcing.
Here’s the global average temperature anomaly since 1880 (let’s use the data from NASA, shall we?).
NOAA (National Oceanic and Atmospheric Administration) has caused quite a stir with their latest report about sea level rise. The statement attracting the most attention is:
Sea level along the U.S. coastline is projected to rise, on average, 10 – 12 inches (0.25 – 0.30 meters) in the next 30 years (2020 – 2050), which will be as much as the rise measured over the last 100 years (1920 – 2020).
The one getting far less attention than it should, is:
Sea level rise will vary regionally along U.S. coasts because of changes in both land and ocean height.
Unlike most of the critics of the report (especially the loudest ones), I actually took the time to read it.
Back in 2010, the North Carolina’s Coastal Resource Commission published the North Carolina Sea Level Rise Assessment Report. Dave Burton of “NC-20” (a trade group for business interests in the coastal counties of NC) ridiculed their results, claiming that the only sensible way to forecast future sea level rise was to fit a straight line to the data from the past, and extrapolate that into the future.
Back in 2016, Florida’s Climate Science Advisory Panel (CSAP) produced a Recommended Projection of Sea Level Rise in the Tampa Bay Region. Willis Eschenbach ridiculed their results that sea level might rise faster than it has in the historical record, saying
“Finally, look at the St. Petersburg sea level dataset, or any Florida sea level dataset. None of them show any significant acceleration, despite covering the period of recent warming. Warming but no acceleration of sea level rise … oops.”
NOAA (National Oceanic and Atmospheric Administration), in their latest report, tell us that much of the U.S. may experience a foot of sea level rise by the year 2050. Anthony Watts ridicules their results, claiming instead that sea level has been rising at a steady rate for over a century and we have no reason to believe it will do otherwise.
If you look at the graph of COVID-19 infections in the U.S., the “omicron wave” is rather obvious:
Yes, it’s that giant spike in the infection rate at the end, the one that has hit us this year.
Let me plot that data again, as a blue line, but reduced by a factor of 100. I’ll also delay it 20 days. That way, we’ll see what 1% of daily infections looks like, when it’s delayed 20 days. But I’ll expand the y-axis so that it covers such a small region, the huge “omicron spike” this year spills over the top of the graph!
That’s because I’ll also plot, as red triangles, the mortality rate, the number of deaths per day (per million population).
And that’s the point. UNTIL NOW, the death rate from COVID-19 in the U.S. has always been higher than 1% of the infection rate delayed 20 days. UNTIL NOW.
HAPPY NEW YEAR! CRAPPY START!
I hope you enjoyed your new year’s celebration, and we all enjoy saying “goobye and good riddance” to 2021. We’re hoping for much better in the year 2022. So I’ll be that jerk who starts the year by telling you some bad news.
2022 might turn out to be a wonderful year — but it will start horribly, because the omicron variant of COVID-19 is so astoundingly contagious, the rate of infection is “through the roof” — i.e., faster than ever before in the USA.
