In 2000, Hansen advanced an alternative view of global warming over the last 100 years, arguing that during that time frame the negative forcing via aerosols and the positive forcing via carbon dioxide (CO 2) largely balanced each other out, and that the 0.74±0.18 °C net rise in average global temperatures could mostly be explained by ...
Nov 2, 2023 · Global warming may be happening more quickly than previously thought, according to a new study by a group of researchers including former NASA scientist James Hansen, whose testimony before...
Mar 29, 2024 · James Hansen, Makiko Sato, Pushker Kharecha Accumulating evidence supports the interpretation in our Pipeline paper: decreasing human-made aerosols increased Earth’s energy imbalance and accelerated global warming in the past decade.
Since the late 1970s, he has focused his research on Earth’s climate, especially human-made climate change. Dr. Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue.
Jun 26, 2018 · Three decades after Hansen first warned Congress about global warming, the overwhelming scientific consensus is that he was right—and most would say that far too little has been done to address the threat.
Sep 15, 2021 · James Hansen, a climate scientist who shook Washington when he told Congress 33 years ago that human emissions of greenhouse gases were cooking the planet, is now warning that he expects the...
Jan 12, 2024 · 12 January 2024 James Hansen, Makiko Sato, Reto Ruedy. Abstract. Record global temperature in 2023 helps reveal acceleration of global warming on decadal time scales.
