Climate overshoot - when we go past 1.5 degrees there is no going back | New Scientist Weekly 271

If we overshoot 1.5 degrees of global warming, there is no going back. The hope has long been that if - and when - we blow past our climate goals, we can later reverse the damage. But there’s no guarantee we can bring temperatures back down, according to a paper published in Nature this week. The report suggests it would take decades to get back to normal - and some of the more devastating consequences will be irreversible. Hear from a variety of experts on the problem of climate overshoot.
Living bacteria have been discovered in 2-billion-year-old rocks, making them very, very old. Find out how these primitive microbes survived for so long - and why this discovery is exciting news for the quest to find life on other planets.
Do you think you’ll make it to the ripe old age of 100? Human life expectancy has steadily been going up and up - but now it’s grinding to a halt, looking unlikely to exceed 84 for men and 90 for women. What’s going on? Is there a limit to human ageing, or is something else at play?
Hurricane Milton has caused immense damage across Florida and the death toll is rising. As it draws power from the hot oceans, there’s good reason to believe climate change is to blame for its rapid intensification. Hot on the heels of Hurricane Helene, why are extreme weather conditions picking up again so quickly?
Hosts Rowan Hooper and Chelsea Whyte discuss with guests Michael Le Page, Carl-Friedrich Schleussner, Joeri Rogelj, Wim Carton, Sam Wong, Carissa Wong and James Dinneen.

When we are gasping for our last breaths I can imagine hearing, “I told you so.” from scientists without solutions.

The next El Nino will push us over 2 Celsius.

Tired of hearing about climate change. I want to hear solutions. Like all ICE vehicles from chainsaws to ocean trade vessels immediately stopped. After everyone starves to death there will be fewer carbon emissions.

There are no "solutions", just as there is no way to reverse the sun rising in the east and setting in the west. The climate has been changing from Earth's beginning: the poles were once tropical and the Sahara was once under water - and at another time a jungle - then there were the various Ice Ages, some of these events long before man set foot on the planet. Climate change cannot be modified, no matter what any "experts" have to say.
