mdsolar writes: More than 100 geoscientists are calling on the American Geophysical Union to drop ExxonMobil as a sponsor of its annual earth science conference in response to the company's years of spreading climate denial views. The call appeared in an open letter posted Monday morning on a science website called The Natural History Museum. The oil giant Exxon has a history of funding organizations that perpetuate climate misinformation and try to thwart policies that address climate change (in direct conflict with the earth science association's mission and funding policies), the scientists said in their letter to Margaret Leinen, president of the American Geophysical Union (AGU). "AGU has established a long history of scientific excellence with its peer-reviewed publications and conferences, as well as a strong position statement on the urgency of climate action," the letter said. "But by allowing Exxon to appropriate AGU's institutional social license to help legitimize the company's climate misinformation, AGU is undermining its stated values as well as the work of its own members," it added.
