Back To The Future

AI Overview : James Hansen remains an active climate scientist today, directing the Climate Science, Awareness and Solutions program at Columbia University. In 2025, he co-published a paper arguing that global warming has accelerated and that current climate sensitivity estimates are underestimated. He continues to warn about the potential for severe climate impacts, arguing that the 2 Deg. C climate target is likely unattainable based on his latest research. You can watch this video to learn more about James Hansen's perspective on climate science:

Current role: He heads the Climate Science, Awareness and Solutions program at Columbia University's Earth Institute.Recent research: In 2025, he released a paper titled "Global Warming Has Accelerated," which builds on his previous work to argue that warming is accelerating and Earth's climate sensitivity is higher than the IPCC estimate.Key findings: His latest research suggests that the 2 Deg. C target is unattainable and points to the underestimation of aerosols' cooling effect and the impact of reducing aerosols from shipping as a cause for recent warming spikes.Ongoing advocacy: Hansen continues to be a prominent voice on climate change, advocating for action and raising concerns about the severity of climate change impacts on ecosystems and food production. This video presents James Hansen's views on a new paper about global warming:
