Old Habits – The Quadra Project

Some old habits are difficult to break. Since the global pledge to reduce carbon dioxide emissions, 30 years of half-hearted trying has not stopped them from going up rather than down. The result is exactly as scientific modelling has predicted—global temperatures are rising. The year 2023 was the hottest in about 125,000 years after temperature records were recorded for consecutive months from June to December of 2023, and then for January and February of 2024. The final calculations for 2023 indicate that we have reached 1.32°C above the pre-industrial temperature, exceeding the 2019 record by 0.4°C. Yes, it’s a warmer El Niño year, but that only accounts for 0.2°C of the 1.32°C. New 2024 calculations indicate we have reached 1.48°C above historical levels.

The Quada Project: Beyond 1.5°C

The consensus of scientists is that limiting the global temperature rise of 1.5°C is no longer reachable, but limiting it to below 2.0°C is possible, according to an analysis of global information undertaken by the Inevitable Policy Response study from Britain (Jacob Thomae, New Scientist, 2 December 2023, “Keeping our Cool”). We were once on a path to 3.5°C, which has been reduced to 2.4°C by 2100. But the IPR study thinks that we have a 90% chance of holding the temperature increase to between 1.7 and 1.8°C, primarily because of the progress that has been made on green energy since the Paris Agreement in 2015. This is the good news.

The Quadra Project: Cop 28

The 28th session of the United Nations’ Conference of the Parties, known as COP28, concluded at the end of 2023 in Dubai of the United Arab Emirates. It was as much a success as can be imagined when a so-called “petro state” is hosting and chairing an international meeting that hoped to reduce global carbon emissions.

The Quadra Project: “Damned Fools”

The mood in the U.S. Senate on June 23, 1988, was expectant and tense. A prominent scientist from NASA, Dr. James Hansen, was giving testimony about the condition of the world’s climate and the implications for both the United States and planet Earth as a consequence of continued global carbon dioxide emissions. His prognosis was serious and sobering. His evidence unequivocally supported the conclusion that the results would be a catastrophic rise in temperature, with a consequent melting of ice caps, an uncontrollable rise in sea levels, and widespread disruptions in normal weather as carbon dioxide levels rose. Other scientific evidence was equivocal, but Hansen argued that no other explanation but carbon dioxide emissions came “anywhere close” to explaining the existing weather anomalies.
