Climate change

Of course, dirt also tells stories of human triumph and transgression. With one scan from an X-ray fluorescence gun, you can tell whether a soil sample came from Cambridge or Dorchester, based on the amount of lead particulates present. A Ziploc bag full of dirt is also a history of redlining, white flight, and devastating arson, committed by property owners for whom the cost of maintaining the land surpassed the worth of those who called it home. Dirt is an archive of human attitudes toward the nonhuman world — our hubris in thinking ourselves separate from it, though we arose from it, and will inevitably return to it.

Pope Francis wrapped up a four-day trip to Japan on Tuesday by turning from the anti-nuclear message that was the backbone of his visit to other key campaigns of his, urging students to defend the earth and show greater compassion.

The Trump administration has formally notified the United Nations that it will withdraw the United States from the Paris Agreement, the first formal step in a one-year process to exit the global pact to fight climate change, U.S. Secretary of State Mike Pompeo confirmed on Monday.

On Friday, Sept. 20, driven by our faith and by our profound concern about climate change, we will be joining young people from around the world in a climate strike. We will join with youth who, frightened by the impact that a hotter planet will have on their lives and angry that adults have done so little in response, are demanding that world leaders take transformative action to address the emergency that we face. Millions of us will take to the streets to demand a right to a future for generations to come.

THIS YEAR, THE seasonal rains in Kenya came two months late. “Even the weatherman can’t forecast the weather,” Stephen Katama, a local shopkeeper in Nairobi, told me when I traveled to East Africa in June. “We can’t tell the difference between the summer and winter here anymore.”

During the past two decades, rain in sub-Saharan Africa has increased in frequency and intensity, creating dangerously erratic patterns of rainfall and drought. A single day’s downpour may bring the amount of rainfall normally expected over a period of eight months, wreaking havoc on the livelihoods of countless subsistence farming families across Kenya and Uganda.

Sub-Saharan Africa is among the regions projected to see the worst of climate change in the coming decades. I traveled with the Climate Witness Project, hosted by the Christian Reformed Church in the U.S., to Nakuru, Kenya, and North Teso and Soroti, Uganda, to visit farming communities facing extreme shifts in weather patterns.

As the climate crisis intensifies and crystallizes, the tangible effects of climate change today are disproportionately dispersed on both the national and global scale. Communities and entire nations who do the least to contribute to rising greenhouse gas emissions bear the enormous burden of climate disaster first and worst on their bodies and their livelihoods.

“FOR A LONG TIME, people were scared to talk about climate change in its stark reality because they thought people weren’t ready to hear that story. But after the Intergovernmental Panel on Climate Change issued its 2018 report laying out the situation we’re in with the climate, Extinction Rebellion started a movement to tell the truth and act as if that truth is real.

SOON AFTER SENATE Majority Leader Mitch McConnell brought the resolution for a Green New Deal to a sham procedural vote in March, a clip of its co-sponsor, Alexandria Ocasio-Cortez, went viral.

“You want to tell people that their concern and their desire for clean air and clean water is elitist? Tell that to the kids in the South Bronx which are suffering from the highest rates of childhood asthma in the country,” Ocasio-Cortez said. “Tell that to the families in Flint whose kids’ blood is ascending in lead levels.”

It was an illuminating statement. The Green New Deal had rapidly emerged on the heels of a report by the U.N. Intergovernmental Panel on Climate Change that puts the deadline for massive, coordinated action to avoid the worst of climate change at 12 years out. Now is the time for an audacious proposal of the kind climate activists have long pushed for, one that matches the planetary crisis in scale and scope.

Seemingly every week a new major report comes out sounding the alarm about the escalating crisis of climate change. You may have missed two of these from just this past week that join a drumbeat that often causes me to lose sleep as I worry about the future that my 6- and 8-year-old sons will inherit. First, on Saturday the sensors at the Mauna Loa Observatory in Hawaii indicated that concentrations of the greenhouse gas has reached 415 parts per million (ppm), which means that for every 1 million molecules of gas in the atmosphere, 415 are made up of carbon dioxide. This means that even if we manage to move rapidly toward renewable energy and use other measures to help stanch the steady flow of carbon dioxide into the atmosphere, the next generation will likely be saddled with permanent negative consequences of our artificially elevated levels of CO2. Also last week, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (I.P.B.E.S.), a research arm of the United Nations, told the world that we may be on our way to losing as many as a million plant and animal species. The 1,000-plus page report details the effects of climate change on marine and other wildlife and emphasizes like never before the devastating impact of biodiversity loss to humans.
