James hansen global warming wrong predictions

35 years since the first climate change predictions – were they alarmist?

Since the 19th century, researchers have been warning about the global repercussions of human actions. James Hansen’s research group at  was the first to confirm that the increase in greenhouse gas emissions was altering the planet’s climate.

In their scientific article, published in the Journal of Geophysical Research, they outlined how they developed the first predictive climate model that, taking into account greenhouse gas emissions, warned about the climate change that was already underway and the potential future scenarios.

At the time, this prediction was considered catastrophic and faced criticism from various sectors, including the oil industry, one of the largest contributors to greenhouse gasses emissions worldwide.

Were the early climate predictions really that inaccurate?

Critics of anthropogenic climate change often claim that climate predictions are consistently

James Hansen is back with another dire climate warning

Climate scientist James Hansen is frustrated. And he’s worried.

For nearly 40 years, Hansen has been warning the world of the dangers of global warming. His testimony at a groundbreaking 1988 Senate hearing on the greenhouse effect helped inject the coming climate crisis into the public consciousness. And it helped make him one of the most influential climate scientists in the world.

Hansen has spent several decades as director of NASA’s Goddard Institute for Space Studies, and now at 82, he directs Columbia University’s Climate Science, Awareness and Solutions program.

In the years since his seminal testimony, many of Hansen’s basic scientific predictions about the Earth’s climate future have komma true. Greenhouse gas emissions have grown, and global temperatures have continued to rise. The world’s glaciers and ice sheets are melting and sea level rise is accelerating.

But Hansen has been disappointed with the scientific

It’s 30 years since James Hansen testified before the US församling about climate change. In the same year, he published a paper that produced some forecasts. I wasn’t going to write about this as there are a number of articles discussing what Hansen presented and highlighting how it’s stood up remarkably well. There’s Eric Holthaus in Grist, Gavin Schmidt at Realclimate, Zeke Hausfather at Carbon Brief, and Tamino at Open Mind.
Patrick Michaels and Ryan Maue have also written an article looking at how Hansen’s global warming predictions have stood up. They conclude that they haven’t stood up very well. Drawing this conclusions, however, requires making some rather odd claims. For example

Global surface temperature has not increased significantly since 2000, discounting the larger-than-usual El Niño of 2015-16.

Well, if you leave out some data you can draw all sorts of conclusions. However, why was the 2015/2016 El Niño warmer than the 1997/19
