Climate Change: What happens If The World Warms Up By 3°C?

Even if global warming is limited to 2°C, the chances of avoiding a 3°C increase are slim - and that could set off a devastating spiral of climate change.

its amazing how little time on the news and tv climate change is given. We're looking at a possible extinction of the human race, and complete ruin of this beautiful, and only world we call home. Governments need to stop caring so much about money and work to try and heal this planet as best they can

[ilikeceral]

Keep in mind 3c is the estimate given by the UN. So yeah.

A quick warming factoid. The units are Zettajoules / year:
warm the melt the
ocean ice
Deglaciation: 1.6 1.3
2000-2018 AD: 13.7 0.18
"Deglaciation" is the annual average over 12, 500 years of significant sea level rise 20, 200 to 7, 500 years ago, averaging 10.5 mm / year and always >2.7 mm / year.
"2000-2018 AD" is the annual average over 19 years of 2000-2018 AD.
One conclusion is that the ocean has already started warming but the ice hasn't started melting yet.
Incidentally, the 13.7+0.18=13.88 / year is the precise measure of what's referred to as "climate lag" or "in the pipeline" for future increase of Global Mean Surface Temperature (GMST) right now.

Hurricanes are already crazy these days. They have been since 2015 and getting worse

[EmeraldView]

We're toast.

Can't say we don't deserve it.

[Amranwen]

It's 2022 and we are almost at this level :(

[xchopp]

This reminds me a bit of Wake Up, Freak Out.

[ToneWrench]

Utterly unneccessary music in the background. No mention of tipping points. It won’t stop at 3 degrees, will it? All this will do is allow complacency.

[acidvortex]

We are already reaching this point and its almost 2023.. going to watch the 4-6 warmer video to see what coming in the next 5-10years.. God Help us All ... =(

[healthandwealbeing]

Look at the hurricane in Florida now worst ever we dont have long left on this planet 20 to 50 years the most

[AmiChenMillsNaim]

Well, this is all already happening. Here we go.

[PhongLe-dlox]

Meanwhile, Sky New Australia is trying really hard to discredit climate change warnings.

[HazyPurpl]

Netherlands will be fine... we have dijken

[Ps]

Warmest November ever…but I dont mind..

[김하준-ck]

that cool there are many things I didn't know that

[StressRUs]

So, now, 8 yrs. on, we're at 1.65degC above the 1991-2020 baseline and increasing at 0.214 degC annually, so we can expect 2 degC by 2027, 2 1/2 yrs. hence, and 3 degC by 2032, 8 yrs. on. That's all folks.

[zerone]

as of jun3 2024 this is now most likely to happen. 86% chance we hit 3 degree rise

[TheOriginalFreak]

3 million years ago?!?!
Try less than 200, 000 years ago!!!
Antartic Ice Core data recognized broadly, if not universally by climate change experts, clearly shows global temperatures at least 3C about current average temps as little as 140, 000 years ago, as well as again around 230, 000 years ago, both time periods during which modern humans existed on Earth, and continued to exist seeing as we are all here to read this comment.

[notme]

Has anyone stated clearly that all of this is merely speculation and not based on facts?

[mattlm]

How can plants survive without absorbing CO2?
