The main purpose of this ongoing blog will be to track planetary 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: A Dire Glacier Report for Earth Day
Dear Diary. Happy Earth Day everyone. Every Earth Day we look back on events that help shape our world towards a more positive environmental outcome. Here is what I mentioned last year, being a bit too pessimistic concerning Build Back Better. Thank goodness cooler heads prevailed so that Build Back Better did indeed pass Congress:
Extreme Temperature Diary- Friday April 22nd, 2022/Main Topic: Earth Day 2022 With No Green New Deal – Guy On Climate
Like during 2022, this year we have a similar problem- ever more dire weather and climate reports. To mark Earth Day 2023, we have a terrible report from the United Nations concerning glaciers. I fear that going through the rest of this decade we aren’t taking the climate crisis seriously enough to avoid an overall catastrophe from rising seas. Plans like Build Back Better aren’t all encompassing enough to transform civilization run by all electric green infrastructure.
It is only by highlighting these problems that perhaps I can give a more positive report on all subsequent Earth Days than on this one for 2023. Here is that report on the sad state of glaciers from PHYs.org:

UN Reports ‘Off The Charts’ Melting Of Glaciers
By Robin MILLARD
The world’s 40-odd reference glaciers saw an average thickness loss of more than 1.3 metres between October 2021 and October 2022.
The world’s glaciers melted at dramatic speed last year and saving them is effectively a lost cause, the United Nations reported Friday, as climate change indicators once again hit record highs.
The last eight years have been the warmest ever recorded, while concentrations of greenhouse gases such as carbon dioxide hit new peaks, the UN’s World Meteorological Organization said.
“Antarctic sea ice fell to its lowest extent on record and the melting of some European glaciers was, literally, off the charts,” the WMO said as it launched its annual climate overview.
Sea levels are also at a record high, having risen by an average of 4.62 millimetres per year between 2013 and 2022—double the annual rate between 1993 and 2002.
Record high temperatures were also recorded in the oceans—where around 90 percent of the heat trapped on Earth by greenhouse gases ends up.
The 2015 Paris Agreement saw countries agree to cap global warming at “well below” two degrees Celsius above average levels measured between 1850 and 1900—and 1.5C if possible.
The global mean temperature in 2022 was 1.15C above the 1850-1900 average, the WMO report said.
Record global mean temperatures over the past eight years came despite the cooling impact of a drawn-out La Nina weather phenomenon that stretched over nearly half that period.
The report said greenhouse gas concentrations reached new highs in 2021.
The concentration of carbon dioxide (CO2) reached 415.7 parts per million globally, or 149 percent of the pre-industrial (1750) level, while methane reached 262 percent and nitrous oxide hit 124 percent.
Data indicate they continued to increase in 2022.
Glacier game lost
WMO chief Petteri Taalas told a press conference that extreme weather caused by greenhouse gas emissions “may continue until the 2060s, independent of our success in in climate mitigation”
“We have already emitted so much, especially CO2 in the atmosphere that this kind of phasing out of the negative trend takes several decades.”
The world’s 40-odd reference glaciers—those for which long-term observations exist—saw an average thickness loss of more than 1.3 metres between October 2021 and October 2022—a loss much larger than the average over the last decade.
The cumulative thickness loss since 1970 amounts to almost 30 metres.
In Europe, the Alps smashed records for glacier melt due to a combination of little winter snow, an intrusion of Saharan dust in March 2022 and heatwaves between May and early September.
“We have already lost the melting of the glaciers game, because we already have such a high concentration of CO2,” Taalas told AFP.
In the Swiss Alps, “last summer we lost 6.2 percent of the glacier mass, which is the highest amount since records started”.
“This is serious,” he said, explaining that the disappearance of the glaciers would limit freshwater supplies for humans and for agriculture, and also harm transport links if rivers become less navigable, calling it “a big risk for the future”.
“Many of these mountain glaciers will disappear, and also the shrinking of the Antarctic and Greenland glaciers will continue for a long-term basis—unless we create a means to remove CO2 from the atmosphere,” he said.
Glimmers of hope
Despite the report’s bad news, Taalas said there was cause for some optimism.
The means to battle climate change were becoming more affordable, he said, with green energy becoming cheaper than fossil fuels, while the world is developing better mitigation methods.
The planet is no longer heading towards 3-5 C warming, as forecast in 2014, but was now on track for 2.5-3 C warming, he said.
“In the best case, we would still be able to reach 1.5 C warming, which would be best for the welfare of mankind, the biosphere and the global economy,” the WMO secretary-general told AFP.
Taalas said 32 countries had reduced their emissions and their economies still grew.
“There is no more automatic link between economic growth and emissions growth,” he said.
In stark contrast to the world leaders of 10 years ago, now “practically all of them are talking about climate change as a serious problem and countries have started acting”, he said.

Items will be archived on this site for posterity. In most instances click on the pictures of each tweet to see each article. The most noteworthy items will be listed first.)
