JAMES HANSEN

The 2022 honoree is Cynthia Rosenzweig, whose computer modeling has shown the impact on global food yield. She talks about her "aha" moment — and the biggest surprise in her findings.

From the archive: a series of pieces from some of our finest writers on the environment.

Rising seas, raging fires, more powerful hurricanes—as the climate changes, so do many facets of life. A look at how 60 Minutes has documented the transformation.

Two U.S. science agencies say 2021 was the sixth hottest year on record globally, part of a long-term warming trend.

Unfettered free trade helped get us into the climate crisis. Perhaps there’s some poetic justice if restricting it can help with the solution.

In the 1980's, a NASA scientist named James Hansen discovered that climate change, driven by carbon emissions, was upon us. Are these disasters climate change? Hansen is the father of climate change science. Scott Pelley: Well, the president says about climate change, science doesn't know. There's about as much scientific consensus about human-caused climate change as there is about gravity.

For more than three decades, climate scientists have accurately forecast how carbon emissions would cause a global rise in temperatures. Hansen has been called the father of climate change science. Stopping climate change before irreversible effects have damaged the planet is possible, some scientists believe. Current projections create a more comprehensive look at how the climate responds to carbon dioxide, including how the ocean and plants can absorb some of the carbon humans have released into the atmosphere. According to the latest models, how much the planet will warm is mostly a function of how much carbon humans have burned up to now.
