Summary of all global warming projections reported by ExxonMobil scientists in internal documents and peer-reviewed publications between 1977 and 2003 (gray lines), superimposed on historically observed temperature change (red). Solid gray lines indicate global warming projections modeled by ExxonMobil scientists themselves; dashed gray lines indicate projections internally reproduced by ExxonMobil scientists from third-party sources. Shades of gray scale with model start dates, from earliest (1977: lightest) to latest (2003: darkest).

New Harvard study puts a number on what ‘Exxon knew’ decades ago about climate science

by Harvard University January 12, 2023January 12, 2023

Cambridge, MA, January 12, 2023 — Climate projections reported by ExxonMobil scientists between 1977 and 2003 were accurate and skillful in predicting subsequent global warming and contradicted the company’s public claims, a new Harvard study shows. In the first ever systematic assessment of the fossil fuel industry’s climate projections, researchers at Harvard University and the Potsdam Institute […]

National parks’ economic benefits put at over $100B annually but on an “unsustainable funding trajectory”

by Harvard University September 25, 2019

Sept. 25, 2019 – A new economic analysis of the U.S. National Park system puts its value to Americans at more than $100 billion, a figure that dwarfs the financially strapped agency’s $2.5 billion budget and underpins a call to change how what has been called “America’s Best Idea” is financed. The report comes as […]

Nitrous oxide emissions from thawing Alaskan permafrost are 12 times higher than previously assumed

by Harvard University April 15, 2019

April 15, 2019 – About one fourth of the Northern Hemisphere is covered in permafrost. Now, these permanently frozen beds of soil, rock, and sediment are actually not so permanent: They’re thawing at an increasing rate. Human-induced climate change is warming these lands, melting the ice, and loosening the soil. This may sound like any […]

Millions may face protein deficiency as a result of human-caused carbon dioxide emissions

by Harvard University August 2, 2017

BOSTON, MA, Aug. 2, 2017 – If CO2 levels continue to rise as projected, the populations of 18 countries may lose more than 5% of their dietary protein by 2050 due to a decline in the nutritional value of rice, wheat, and other staple crops, according to new findings from Harvard T.H. Chan School of Public […]

Survey finds Medicaid enrollees satisfied with coverage, physician access

by Harvard University July 10, 2017

BOSTON, MA, July 10, 2017 – Enrollees in Medicaid reported in a nationwide survey that they’re largely satisfied with the health care they receive under the program, according to researchers at Harvard T.H.
