1.5°C warming in next 10-20 years, world fails to meet key climate goal: IPCC

"The IPCC report also underlines that human actions still have the potential to determine the future course of climate change and can strive to keep global warming under 2°C

The world may have lost the opportunity to keep global warming under 1.5 degrees Celsius (°C) above pre-industrial levels. The 1.5°C global warming threshold is likely to be breached in the next 10 to 20 years (by 2040) in all emission scenarios, including the one where carbon dioxide (CO2) emissions decline rapidly to net zero around 2050, the intergovernmental panel on climate change (IPCC) said on Monday.

In a stark warning to world leaders, the 42-page summary for policy makers titled: Climate Change 2021: The Physical Science Basis drafted by 234 scientists from 66 countries warned that global warming of 1.5°C relative to 1850-1900 levels would be definitely exceeded under intermediate, high and very high emission scenarios and will be “more likely than not to be exceeded” even when countries agree to switch to net zero emissions by 2050."

...

"The IPCC projections are expected to be a wake up call for world leaders ahead of UN climate negotiations (COP 26) in November. “The new IPCC report tells government leaders exactly what is at stake at COP26. Without rapidly cutting carbon dioxide emissions to net zero levels, we are headed for a 3°C hotter world with more frequent weather extremes, and dangerous disruptions in the climate. It is high time that developed countries seal the deal on adaptation finance and clean technology partnerships at COP26,” said Ulka Kelkar, director of the climate programme at the World Resources Institute, India."

IMO the earth will lick its wounds and heal itself after we're gone.

There have been warnings, largely ignored, about Climate Change for the past 20 or 30 years. I doubt seriously that anything will be done to reverse this trend. Getting all the nations to reduce their pollution, and control their populations is, IMO, wishful thinking. By the time that the vast majority of nations would come to any meaningful agreements, the "tipping point" will have long passed.

The people in the "developed" nations will be Very reluctant to give up most of our modern conveniences, while the poorer nations will have little means of controlling their problems.

Temperatures will continue to rise, more severe storms will be commonplace, agriculture will be severely impacted, and millions will be dying every year from a combination of weather and starvation. Glaciers and ice fields will melt at an increasing rate, putting most coastal cities and populations at risk from rising oceans. Fresh water supplies will decline as groundwater is depleted,

Even if all fossil fuel usage was stopped in the near future, the release of Methane from the warming oceans, and the permafrost in Siberia, Alaska, and northern Canada will continue to enter the atmosphere in increasing amounts...and Methane is a far more serious greenhouse gas than fossil fuels.

Humanity is headed for a brick wall....probably by the latter half of this century. None of us will live long enough to see the consequences, but our grandchildren and beyond will be living in unimaginable conditions.
 
Thankfully, I won't be here in the future. I don't believe climate change will be like a few extra days of summer like weather. Our climate is a vast complex of forces, which are partially understood. We can only guess the extent of what climate change really is. But from history, we know civilizations break down with prolonged erratic weather, such as draughts. I feel there will be wars, devastation, and mass death in our future, caused by our inaction in preventing a human made catastrophe.
 
All through this planets entire history, there has been radical climate changes. Most had nothing to do with humans. With or without us lowly humans, this planet will continue to do what it has for eons. Always amazes me the human arrogance to think they can somehow control what this planet does.
 
From active volcano's alone, A total of 271 million tons of CO2 are released annually. Underwater volcanoes emit between 66 to 97 million tonnes of CO2 per year. And don't fall for the line that underwater releases are absorbed by the sea bed, BS. and are therefore harmless to the planet.
Also spewed out are multiple poisons; Sulfur dioxide, Hydrogen sulfide and Hydrogen halides (HF, HCl, HBr) a combination of toxic acids.
Still think we humans are the problem?

Yeah, especially the ones who don't care about the planet or any species other than homosapiens. Oh, and to all that kind of humans, the animals we've driven/are driving extinct said to say "Thanks for nothing!" (Except the fire ants and scorpions; they say "We'll see ya in hell!") :devilish:

Actually almost twice that. Rachel Carson's 'Silent Spring' was released in 1962, that's 59 years ago. The first Earth Day was 4/22/70. But there have always been big bucks pushing the 'oh it's just normal climate variations' line. Despite the fact that some cities were able to improve air quality.

BTW i agree with and applaud the rest of your remarks, altho i sometimes feel the tipping point may have snuck by us already.

Whenever people in our age bracket start bashing young people i usually bring up two things:
1) Who raised them and educated them?
2) Have you ever thought about the messages we've been sending them for the last half century? i won't list them here, borders on 'political' topics, controversy adjacent as it were. But i will say i feel they all add up to: If it doesn't impact someone personally--"We don't care how it impacts you, even if you are my progeny." Of course that's not all of us, but an awful lot of us. Another thing i have issues with is folks i see on FB getting all sappy about how much they love their grandchildren but they won't inconvenience themselves to work toward a better future for them.

This! A few years back, was talking to a 40ish guy who works in the financial industry; he said that a client who was worried about their finances in light of climate change; he told the client, "Naw, don't worry about any of that." Client says, "What?! You're not worried about it?!" Finance guy: Nope. Client: Why not?! You've got skin in the game, you know, your kids? Don't you worry about what kind of world we're leaving them with? Finance guy: Nope. They're getting stuck with the world they're getting stuck with just like I got stuck with the world I got stuck with.

What a lousy attitude to have, not only toward anyone's kids but especially your own. :cautious:

What am I supposed to do about it? China is the main offender. Unless we invade them and make them stop building coal-fired electricity plants, we haven't a chance of turning things around. All the UN talk and treaties is just blather.

Have you noticed that China's getting cozy with the Taliban lately? Afghanistan has major coal deposits.
The CCP said they'll activate their new thorium nuclear plant very soon, but it's small, a prototype, and maybe just for "show"....we'll see.

That's right...the planet has had many heat and cooling cycles over the millions of years. Back then, there weren't over 7 billion humans on the planet, and if there were any here during the last cycle, they just folded their tents and moved North, or South, as conditions changed.

Try moving today's populations, and abandoning most of our cities and infrastructure.

This is sort of the ultimate in "going green" -- let's get rid of all the people so the other life forms can flourish.

All I can say is, you first!

When you find some algae who can play a late Beethoven string quartet, give me a call.

As much as I like Beethoven, I'd trade his music in a red-hot minute to save life, any life, even if it wasn't "important" human life (gasp). I can hum Beethoven's 5th just fine; but once the polar bears are gone, I'm gonna be even more pissed off than I am now. And Wagner?! That anti-semite?! Don't get me started...

It's a form of nihilism.

I'm a nihilist, yet I want to protect the environment. I don't like breathing all this smoke from forest fires caused in part by global warming. And I enjoy a nice walk in the woods and other outdoor activities.

While I don't believe there's any meaning to life other than trying to make the most of it while we're here, I'm also a pragmatist. We're better off protecting the environment rather than just raping it of all its resources leaving a sh*thole for those who come after us. Why do I care about those who come after us? I don't know. It just seems like the right thing to do. It has nothing to do with any religion or concern with what happens to me after I die. I've always been kind of an environmentalist, even when I was a little kid. My parents weren't environmentalists, nor were any of my friends. Who knows?
