James Hansen: Why I must speak out about climate change

[juliancribb]

As powerful and relevant in 2023 as it was in 2011. Nothing has changed, except all climate indicators have got worse, at rates much faster than anticipated back then.

I suggest that anyone doubting his argument read his book, Storms for my Grandchildren. The man is a solid creditable scientist and should be respected. Instead of arguing about this, we should all put our energy towards turning this phenomenon around so that we survive as a species.

Eleven years later it's still business as usual.

I have just watched 'The Campaign Against the Climate' and saw that Shell and ExxonMobil knew about the climate change around 10 years early of James Hansen climate change testemonial on Congress. They could agree with him, but they didn't.
Now, 2021, the IPCC report sets the red alarm and we still didn't do too much.

[sobolanul]

11 years passed and we still only debate and little has been done.

I became a climate change believer after i watched this. I had been unsure on whether humans were responsible or not. Thank you.

What about reducing Fossil Fuel Subsidies?

[PetersJazz]

Great James Hansen. You put it very clear. Hope more people would listen.

[dookiecheez]

When people say it's already too late they seem to be talking as though once it get's bad enough, that our emissions will not significantly impact the future any further. Even if we pass a threshold at which certain things beyond our control will occur, the degree to which we further aggravate and speed up the changes is still of importance. The simplest way I can explain this is simple:
The slower it happens the better. Don't give up.

What caused global warming and CO2 rise when we weren't burning fossil fuel?

[joshmuralt]

ALL EXTREME conditions anywhere, large number of hurricanes, low number of hurricanes, flooding, droughts, snow storms, all are caused by global warming/climate change in-fact any weather at all is caused by changing climates and their always changing.

Chilling. What a dedicated man! Fantastic that he has given so much to this effort. And thanks also to TED.

Professor Siems said as the Earth warmed, more vapour could be held in the air. It meant there was more moisture available to fall as rain when a storm developed.
The research, which was published in the journal Nature Climate Change, was said to take better account of the impact of aerosols on the water cycle than previous weather studies.
NASA's ERBE helps scientists better understand how clouds and aerosols, as well as some chemical compounds in the atmosphere affect Earth's climate.

[poppyd]

Still a great presentation, and a prescient one.

[TheLucqui]

James Hansen is a true hero. He spoke out about this when no one else would

[jitsroller]

The ipcc report shows a cooling trend for the last 15years. I know that's not what the media is saying but that's what the report showed.

[bulldogmadhav]

Reading the comments are just depressing

[MyHelixnebulae]

Thank you, James Hansen, for this utterly important talk, I will share it!!

[jitsroller]

It has everything to do with why the ice melts on the northern poles. It's going to keep melting every time the axis makes the ice get to close to the sun. Everything else is a guess. The facts are that this happens every 25, 000 years.

I can tell you the climate recently warmed up: all snow went. But fortunatelly climate changes and there will be a cooling soon, 6 month or so and it will even get so cold the snow is going to fall. Then we can ski and look forward to the next time climate changes and we can again heat the swimming pool.
