Dire warnings from the IPCC

The Climate, Health & Equity Brief is GMMB’s take on the last two weeks’ news on the current impacts of climate change. If you haven’t subscribed yet, you can do so by clicking here.

Hot Topic: Necessary choices. History will note what this year’s UN International Panel on Climate Change (IPCC) Report lays bare: We have both the knowledge and the tools to curb emissions and avoid cataclysmic global warming—and if we fail to do so, it will be due to a lack of collective and individual will.

Global temperature rise is now set to exceed 1.5°C (2.7°F) within just 10 years—a situation the IPCC says is “unequivocally” due to human-caused greenhouse gas emissions. The report states that without deep emissions reductions, cataclysmic scenarios beyond 3°C (5.4°F) of warming this century are much more likely, with immense risks to humanity.

With each passing year that emissions continue, the necessary solutions grow in intensity and difficulty. Decades of inaction have denied us the luxury of a gradual transition to a more sustainable economy and society: The panel reports that even limiting warming to less than 2°C will require “deep, rapid and immediate” efforts across all sectors and warns that any time spent beyond the 1.5°C threshold will make the gradual reduction in global temperature more difficult to achieve due to unlocked feedback loops.

Despite the bleak outlook, the report notes that energy transition policies and technologies are making a real, meaningful difference. In some regions, wind and solar energy are now cheaper than fossil fuel use. In the past decade, many countries have proved it is possible to cut emissions significantly while still growing their economies. And despite the inequitable impacts of climate change, efforts like the UN’s loss and damage fund could result in the world’s richest and most developed nations assisting poorer nations with just solutions.

The climate crisis now demands that we, like the world’s governments, reflect on our choices in this critical period—including but not limited to the way we eat, travel, consume and vote. As IPCC chairman Hoesung Lee noted, “the choices we make now and in the next few years will reverberate around the world for hundreds, even thousands, of years.”

The latest IPCC report says the world will likely surpass 1.5°C (2.7°F) of warming within 10 years, and “every increment of warming will intensify multiple and concurrent hazards” without “deep, rapid, sustained reductions” in greenhouse gas emissions. (The Washington Post)

A new report revealed that one-fifth of UK hospitals were forced to cancel operations during a massive heatwave last July—with temperatures reaching as high as 104°F—due to National Health Service buildings not being equipped to withstand the heat. (The Guardian)

Black women environmental justice advocates led by faith are leading the charge to stop the continued pollution of Louisiana’s “Cancer Alley,” scoring some big wins in a region with a large Black population, more than 150 petrochemical plants and abnormally high cancer risk. (Inside Climate News)

New York finalized its list of disadvantaged communities to be first in line for cleanup and climate funding in the state’s multibillion-dollar climate plan by using 45 different environmental and socioeconomic data points, like poverty rates, asthma emergency room visits, projected flooding rates, and racial demographics.

The Biden administration approved the auction of 73 million acres in the Gulf of Mexico for offshore oil drilling as required by Sen. Joe Manchin’s additions to the Inflation Reduction Act, which could lock in new oil drilling in the Gulf through 2070. (CNN)

The melting Arctic has sparked a geopolitical rivalry for its now-available resources and shipping routes, and President Biden has nominated the first ambassador-at-large for the region as the U.S. military prepares to deal with national security threats from Russia and China. (NPR)

Investigations have found that language in the dire UN IPCC report about the environmental costs of burning fossil fuels and consuming meat was watered down by corporate influence and fierce negotiations between countries protecting their financial and political interests. (Inside Climate News)

A new estimate suggests that 40 of the world’s top livestock producers could see meat and dairy profits fall by a record $24 billion by 2030 as a result of climate change, according to an analysis by collaborative investor network FAIRR. (Bloomberg)
