“The new study includes Exxon’s graphs, models, projections and publications that show it understood how its business would affect the planet, according to the researchers Geoffrey Supran of the University of Miami, Stefan Rahmstorf of the University of Potsdam and Naomi Oreskes of Harvard University. Oreskes previously co-authored the book “Merchants of Doubt,” which detailed the efforts of a small number of scientific researchers who worked to undermine the public’s acceptance of climate science.
“All told, ExxonMobil was aware of contemporary climate science, contributed to that science, and predicted future global warming correctly,” the researchers wrote. “ExxonMobil accurately foresaw the threat of human-caused global warming, both prior and parallel to orchestrating lobbying and propaganda campaigns to delay climate action.”
Exxon spokesperson Todd Spitler rebutted the claims and said the company supports addressing climate change.”

“Exxon’s models aligned with the best science between 1970 and 1990, the paper found. Exxon projected 0.2 degrees Celsius (0.36 Fahrenheit) of warming every decade with a 0.04-degree C margin of error. That figure is close to the 0.19 degrees C rise and 0.03-degree C margin of error derived from 18 government and academic models.
Under one metric, Exxon proved more precise than famed NASA climate scientist James Hansen, who first brought global warming to Congress’ attention in 1988.
“It has been established that, for many years, Exxon’s public affairs strategy was — as a 1988 internal memo put it — to ‘emphasize the uncertainty in scientific conclusions regarding the potential enhanced greenhouse effect,’” the report said. “However, our analysis shows that in their reports and briefings to management, ExxonMobil’s own scientists did not particularly emphasize uncertainty.””
“The EU’s carbon border levy is the latest, and most symbolic, measure to upset the EU’s trade partners. The idea is that producers importing carbon-intensive products into the bloc will have to buy permits to account for the difference between their domestic carbon price and the price paid by EU producers.
The goal of the levy, called the Carbon Border Adjustment Mechanism (CBAM), was to level the playing field for EU producers and avoid companies moving their production over lower climate standards — so-called carbon leakage. For Brussels, the sense of climate urgency is too high to wait for others to follow suit, or to reach a deal at the multilateral or global level.”
…
“Brazil, South Africa, India and China have jointly expressed their “grave concern regarding the proposal for introducing trade barriers, such as unilateral carbon border adjustment, that are discriminatory.” The measure is likely to be challenged at the World Trade Organization.”
…
“The carbon border levy is far from the only measure to make exporting to the world’s biggest trading bloc harder.
Brussels’ Farm to Fork strategy seeks to prioritize sustainability in agriculture by slashing pesticide risk and use in half by 2030. A plan announced last September to ban imports of products containing residues of harmful neonicotinoid insecticides from 2026 has drawn “unprecedented” criticism from other countries, according to a senior European Commission official.
As the Green Deal tightens rules on pesticide use in the EU, new trade barriers are going up, said Koen Dekeyser of the European Centre for Development Policy Management (ECDPM). “Certain farmers can make those investments. Other, more small-scale farmers are likely to seek other markets, for example in Asia,” said Dekeyser.
The EU’s effort to stop deforestation is likely to have similar results.
Under new rules, it will be illegal to sell or export certain commodities if they’ve been produced on deforested land.”
“Even though 2022 was only the Arctic’s sixth warmest year on record, researchers saw plenty of new signs this year of how the region is changing.
A September heat wave in Greenland, for instance, caused the most severe melting of the island’s ice sheet for that time of the year in over four decades of continuous satellite monitoring. In 2021, an August heat wave had caused it to rain at the ice sheet’s summit for the first time.”

“Warming at the top of the Earth raises sea levels worldwide, changes the way heat and water circulate in the oceans, and might even influence extreme weather events like heat waves and rainstorms, scientists say. But Arctic communities feel the impacts first.”
…
“Between October 2021 and September, air temperatures above Arctic lands were the sixth warmest since 1900, the report card said, noting that the seven warmest years have been the last seven. Rising temperatures have helped plants, shrubs and grasses grow in parts of the Arctic tundra, and 2022 saw levels of green vegetation that were the fourth highest since 2000”
“If Congress isn’t willing to end energy subsidies entirely, it could still make energy technologies more competitive by simplifying all 44 energy tax provisions. For instance, it could offer tax credits to companies based on what their emissions are, without requiring that they use any specific technologies to hit those targets. Unlike targeted subsidies, such performance-based provisions have historically led to less greenhouse emissions.”
“what happens inside doesn’t happen in a vacuum. Furnaces and water heaters have to vent their emissions directly outdoors, for example (stoves and ovens face no such requirements), and that pollution doesn’t just disappear. The consequences are exacerbated in communities of color, where homes tend to run on less efficient appliances and communities already bear the burden of greater outdoor particulate matter. One analysis by RMI found that Black Americans are 55 percent more likely to die prematurely from the impacts of fossil fuel appliance pollution compared to white Americans. Another study, published in the peer-reviewed journal Science Advances, found residential gas combustion and commercial cooking to be the largest drivers of the racial disparity in pollution exposure for people of color compared to white people.”

“As the grid is getting cleaner, buildings hooked up to electricity will also have a dwindling footprint and, hopefully, use less energy overall with more energy-efficient machines. But a building that runs on gas will always burn a fossil fuel for its heat. And today that footprint is considerably large: 13 percent of the nation’s climate pollution comes directly from these gas-burning machines.”
