Climate injustice—and the Pope speaks

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: An unjust picture. This week, researchers released the U.S. Climate Vulnerability Index (CVI)—the most comprehensive screening tool to date showing where climate risks most imminently threaten communities throughout the United States. The results showcase the vulnerability of many U.S. communities to floods, fires, droughts, and pollution—and they highlight the ways location, income and lack of access to health care exacerbate these risks.

Developed by researchers at the Environmental Defense Fund and Texas A&M University, the CVI tool, linked below, applied nearly 200 data sets to 70,000 U.S. census tracts to visualize the present-day climate impacts that threaten many U.S. communities. The study paints a particularly bleak picture for the U.S. Gulf Coast, with industrialized communities in the Deep South—which have long suffered from systemic racism and neglect—at greatest risk.

Accordingly, results highlight major environmental justice concerns. Despite being just 12% of the U.S. population, Black residents make up 30% of the population within these top 10 counties. Researchers found that vulnerable groups will be disproportionately affected due to greater exposure to climate risks and lower ability to prepare, adapt, and recover from their effects. Beverly Wright, founder of the Deep South Center for Environmental Justice, declared that “Black communities in the Deep South are in the fight of their lives to protect their community from years of environmental racism.”

Environmental inequity remains a massive challenge not only in the U.S. but globally, as the countries least responsible for the climate crisis increasingly bear its most horrific impacts. In advance of COP28, Pope Francis implored the United States and other affluent nations to do much more to help developing countries in the face of the crisis, and to take urgent and meaningful climate action for the benefit of the planet and humanity.

“The world in which we live is collapsing and may be nearing the breaking point,” the Pope said. “A broad change in the irresponsible lifestyle connected with the Western model would have a significant long-term impact.”

Human Health

Rising heat is undermining health progress globally as it expands the habitat of disease-carrying mosquitoes, worsens air quality, increases heat-related deaths, and leads to more cholera outbreaks, making it the biggest single threat to public health—yet experts say only 0.5% of climate funding is allocated to health projects.

Politics & Economy

According to a new U.S. poll, religiously unaffiliated individuals and Hispanic Catholic Americans are the most likely to believe climate change is caused by humans (76%), while white evangelical Protestants are the least likely to believe so (31%)—with 19% of the latter denying any evidence of climate change at all. (Axios)

Why do you want to preserve today a power that will be remembered for its inability to intervene when it was urgent and necessary to do so?
