The planet is heating up like never before, as ‘ground temperatures’ hit all-time records in the Northern Hemisphere as well as the Southern Hemisphere, and ocean temperatures threaten the world’s major fisheries of the Far North, which are imperiled beyond any known historical precedent. According to the National Oceanic and Atmospheric Administration (NOAA) July 2021 was the hottest month in recorded history for the world. The European Union (EU) satellite system also confirmed that the past seven years have been the hottest on record.
Too much heat brings unanticipated problems of unexpected scale, putting decades of legacy infrastructure at risk of malfunctioning and/or total collapse. Nobody expected so much trouble to start so soon. Nobody anticipated such massive record-breaking back-to-back heat, north and south, to hit so soon on the heels of only 1.2C above estimated baseline for global warming.
In that regard, and with deep concern, the Council on Foreign Relations (founded, 1921) stated: “More than one-fifth of the global population now lives in regions that have already experienced warming greater than 1.5 degrees C (2.7 degrees F), an increase that almost all nations have agreed should be avoided to significantly reduce the risk of harm from climate change.”
Moreover, as further stated by the Council: “Exposure to a sustained wet-bulb temperature of 35 degrees C (95 degrees F), a point of intense heat with extreme humidity (90 plus), has been identified as the limit for human survival. When wet-bulb conditions develop, sweat can no longer evaporate off a person’s skin and the body cannot cool down. Just a few hours of this kind of heat exposure can lead to death… Some regions, including southwestern North America, South Asia, and the Middle East have already endured conditions at or near this limit, and certain areas will experience the effects more intensely than others. One projection indicates that, by 2030, this type of heat wave could afflict over two hundred million people in India alone.”
Notably, according to the International Energy Agency (IEA): Only 8 percent of the 2.8 billion people living in the hottest parts of the world have air conditioners. Furthermore, the Council claims: “The infrastructure of today was not built to withstand surging temperatures.” As follows, global heat is rapidly outpacing infrastructure capacities. This is a surefire pathway to disaster on a scale seldom, if ever, witnessed.
Over time, excessive heat impairs and/or destroys infrastructure. Hot weather, when too hot, causes power lines to sag. When water used to cool power plants becomes too hot, electricity production measurably decreases, and drought conditions lower water levels beyond effectiveness for hydropower plants. This is already threatening in Brazil where hydro amounts to 62 percent of its total installed electric generating capacity. In America, the Hoover Dam, which serves electrical power to 8 million people, is at it lowest level since 1937 when its lake was still being filled.
And, too much heat causes steel-comprising damage to drawbridges. Train tracks can bend under intense heat, which actually caused train cancellations in Europe in 2019. And, planes can struggle to fly in extreme heat conditions. According to the EPA, when cities are exposed to extreme heat, it can magnify heat conditions by up to 15C above surrounding rural conditions, effectively turning major cities of the world into furnaces of trapped heat.
Already, South America’s summer of 2022 is hot as blazes: “Practically all of Argentina and also neighboring countries such as Uruguay, southern Brazil, and Paraguay are experiencing the hottest days in history.” This is according to Cindy Fernández, meteorologist at the official National Meteorological Service.
Argentina, as of January 12, 2022 reported: 129 degrees F ground temperatures that brought blackouts. “This is a heat wave of extraordinary characteristics, with extreme temperature values that will even be analyzed after its completion, and it may generate some historical records for Argentina temperatures and persistence of heat,” according to meteorologist Lucas Berengua.
Thereafter, Argentina’s infrastructure sagged and 700,000 people were without power, and drinking water purification systems went on the blink. Argentina’s ground temperatures echoed readings from the Northern Hemisphere of only 6 months ago, which, in retrospect, served as a foreboding for the southern continent, as it now begins its summer.
The heat has been so bad in Argentina that it was briefly the hottest place in the world, surpassing parts of Australia that usually carry that dubious honor during austral summer. According to BBC News, Australia equaled its hottest day on record at 50.7C or 123.26F in Onslow, Western Australia on January 13th, 2022. The normal average temperature for Onslow (a coastal town) this time of year is 36.5C, not 50C. Additionally, Mardie and Roebourne, two other towns in the area, reported temperatures over 50C. And, in South Australia Oodnadatta reported 50.7C on January 2, 2022.
The summer of 2021 up north found the Anthropocene, the geological period of human influence, turn into the Pyrocene, when a shocking number of wildfires consumed vast areas of the Northern Hemisphere. It was ‘the summer of hell’. Global warming dried out grasslands and forests turned to tinder. The chief of the US Forest Service declared a ‘National Wildfire Crisis’.
Oregon and California fires were powerful enough to create stand-alone weather systems. The town of Lytton, British Columbia burned to the ground like a smoldering matchstick. Ground temperatures in Washington State in June 2021 hit 145F (63C) during an unprecedented Pacific Northwest heat wave too hot to even walk near concrete or squishy asphalt. In Canada’s northwest, Ontario and Manitoba experienced 157 severe wildfires intense enough to create stand-alone weather systems.
Siberia experienced Biblical-scale fires like nobody has ever seen. A study showed the extreme heat driving the fires to levels calculated as 600 times more likely to occur because of climate change. Siberia at its most northern reaches registered a shocking 118 degrees F (48C) in June.
In the Mediterranean region, the summer of 2021 experienced wildfires raging out of control in Turkey and Greece with ground temperatures of more than 127F degrees (53C). There is a point to be made about this disheartening litany of the world succumbing to heat since it’s happening with global warming at only 1.2C above pre-industrial. But, is pre-industrial (same as post-industrial) really since 1880 or 1950, or should it be 1750, or is the entire affair really worse than we’ve been told at any rate? Answer: Look at the evidence and make a judgment.
