We have to consider extreme climate solutions – Watt?

Eric Worrall's paper

“…Thinking like thickening sea ice to prevent collapse…may have once seemed extreme.

We passed the 1.5C climate threshold. We must now explore extreme options

We have no luxury goods that reject solutions until we thoroughly investigate its risks, tradeoffs and feasibility

As a lifelong scientist, I have always thought that if possible, we could find a way to achieve it. However, one of the worst reality we face now is that the world has failed to achieve its climate goals. Last year marked a historic and disturbing threshold: It was the first time that global temperatures were above 1.5C at pre-industrial levels. Without sharp and direct climate action, such violations would not be temporary. Consequences – sea level rise, extreme weather and devastating biodiversity loss – are no longer predicted by the distant future. They are happening now, affecting millions of lives and potentially causing trillions of dollars in damage over the next few decades.

But we must go beyond our direct vision. When I read “The Iliad”, I remembered that it was written 2800 years ago. I often wonder: Will people (as we know that humans still exist) read about our time in another 2800 years? Will they see us as a generation that fails to act, or a generation that makes the choices necessary to protect the planet?

One of the biggest challenges of today’s climate science is that many of the necessary levers to regain control are uncomfortable and even controversial. Thoughts such as preventing sea ice from collapsing or enhancing ocean clouds to reflect sunlight may have been extreme. But, just as we deal with an escalating crisis, we must at least explore these possibilities. We don't have the luxury of directly rejecting solutions until we thoroughly investigate its risks, tradeoffs and feasibility.

We hit 1.5C with some measures, but there is no climate disaster, except in the imagination of scientists like Professor David King. Even if the temperature rises, no climate disaster will occur.

Facing Professor Jin, you and your friends are wrong – a warm world is a more benign world for mankind.

The evidence is that our monkey ancestors thrived in a much hotter world. Ancient – The maximum heat value of Euclidean was 5-8C higher than today, which is the age of monkeys. Our monkey ancestors flourished in the richness of hothouse petm and colonized many parts of the world until Greenland and Siberia, and retreated only when the cold recovered.

My only concern is that our benign warm climate may end soon-not in my life, but that humans are too early and that humans are just beginning to reach their full potential.

Geologically, the Earth is still locked in the late Conzok Ice Age, which began 34 million years ago, still fixing our planet in its frozen grip.

The last Ice Age was too cold, and it might be almost an extinction event.

As we approach a new world glacier, global cooling is much more threatening in the long term compared to global warming. Winter is coming and we don’t have enough coal to drive out the ice.
