The climate crisis reaches a tipping point

Record-breaking July temperatures confirm urgent need for action on climate change

A joint statement released Thursday by the European Copernicus Climate Change Service (C3S) and the World Meteorological Organization (WMO) confirms that the first three weeks of July have been the warmest three-week period ever recorded and predicts that the month will be the hottest ever experienced by human civilization.

Anthropogenic emissions driving rising temperatures

Carlo Buontempo, the director of C3S, noted as part of the statement, “Record-breaking temperatures are part of the trend of drastic increases in global temperatures. Anthropogenic emissions are ultimately the main driver of these rising temperatures.” He continued, “July’s record is unlikely to remain isolated this year, C3S’ seasonal forecasts indicate that over land areas temperatures are likely to be well above average, exceeding the 80th percentile of climatology for the time of year.”

The record broken this July was last set in August 2016, when the global average temperature spiked to 16.92 degrees Celsius (62.46 degrees Fahrenheit), as measured by the US National Oceanic and Atmospheric Administration (NOAA). But since July 3, the worldwide temperature averaged every 24 hours skyrocketed past that, reaching a new height of 17.23 C (63.01 F) on July 6. The coolest day since then was July 14, falling to 16.94 C (62.49 F), still just above the previous peak.

Impacts on Earth’s regions and oceans

Earth’s tropics and Northern Hemisphere have been hit particularly hard by the ongoing heatwave, with temperatures in those regions currently about 0.9 C (1.6 F) and 1.2 C (2.1 F) above average, respectively. Ocean temperatures in the North Atlantic have been shattering seasonal records since March, reaching almost 1.5 C (2.7 F) above average, while world ocean temperatures outside the poles remain 0.8 C (1.4 F) above average, including a new record 21.1 C (69.98 F), also set in March. It is increasingly likely that 2023 as a whole will become the hottest year ever recorded.

Catastrophic consequences and the need for action

Among the most catastrophic consequences of the record temperatures this year have been the wildfires in Canada, which have burned more than 100,000 square kilometers (38,600 square miles), nearly double the previous record set in 1989, and blanketed the North American Northeast with toxic levels of smoke and ash. Large portions of Southern Europe, the Middle East, South Asia and the entire Southern US were or still are under heat alerts. Floods have killed 47 people in the US, including 13 from the flash floods in July, while wildfires in Europe and North Africa have killed more than 40. Hundreds have died from heat stroke in Algeria, China, Cyprus, Greece, Italy, Mexico and Spain.

Moreover, the disasters caused by climate change now are the precursors to even more catastrophic events. The water temperatures off the Florida coast—38.38 C (101.1 F)—and the extent of Antarctic sea ice—more than 2.6 million square kilometers (about 1 million square miles) below average—are indicators of what is to come. Warming oceans threaten critical coral systems and the global plankton population with disease and mass die-off, which in turn threatens the base of the entire food chain. The lack of Antarctic sea ice constantly poses the mortal danger of land ice falling into the ocean, raising ocean levels worldwide and permanently flooding coastal areas where an estimated 3 billion people live.

The role of capitalism in the climate crisis

There is no longer any doubt that global warming has been caused by the exploitation of Earth’s resources by anarchic capitalist production, particularly the essentially unregulated burning of coal, oil and natural gas for a century and a half. The pressing question is for a resolution to the ongoing and accelerating ecological crisis.

In response to the C3S and WMO report, UN Secretary-General António Guterres noted at a press conference that “Humanity is in the hot seat [and] humans are to blame.” This is a false equivalency, and Guterres knows this.
