Climate Change: What Happens If The World Warms Up By 4°C?

After the devastating effects of a 3°C rise in global temperatures, it may become impossible to stop increasing rises.

And just think, right now the permafrost is releasing large amounts of methane.

45° C in England?!?!?!?!? That sounds terrifying! I don’t even want to know about what the temperature would be like on the Mediterranean, Australia, and the US: they would become uninhabitable due to extreme heat and drought! This is seriously terrifying!

And i just started to work on a school project about global warming. What a coincidence lol

[deanfowles]

its going to happen, i suggest everyone learns to accept death in the same way a terminally ill person does. our days are numbered now as they always were. the best thing to do now is to treat each other excellently.

Given that most people on the right consider this man to be a hero, this is will I will never vote for Republicans.

And what about the currently cold places like Canada, Alaska and Antartica?

[hasoon]

Oh god I'm scared I don't want this to happen

[m-pm]

Everyone will move to Mother Russia and Canada 👌

Humanity is responsible to destroy its habitat, the global earth but lucky enough has the ability to mend it, therefore let all of us start now to do whatever each on of us can to take action before the global temperature raises beyond 3 degrees

I hate to say this but we need thanos to snap. Save the planet

We need to plant a billion trees etc, Humans still have the intelligence to turn things around through science....

-Oh boy
-me, one minute before i wrote this comment

[jakejeffery]

Grow thousands of trees to inhale and store all the co2

[jamess]

ah murdoch..even when trying to be scientific a nasty wiff of denial comes through

I just wonder, I am not an expert, just read some papers and some geographical mechanism and I just wonder. Why will amazon became a desert, what will happen to coriolis effect, equatorial air rising etc. World's geographical shape will not change because of the climate change right, and also how could be the ice of antarctica where the average temperatures are -10 degree Celsius in warmest areas fully melted and ocean levels increased fifty meters. Isn't it supposed to be more evaporation and so more water in air and so more rain in suitable areas like tropics and crossings of dominant warm and cold winds. Yes for middle East and Mediterranean, by the increase in temperatures siberian cold air flow will be weaker and so these regions will be more arid and the arid hot places will be literally like hell by the 5 degree Celsius increase. However there will be still oreographic precipitation in mountainous areas of Turkey spain Italy etc. It is not good but I don't think it will be the end of days for Mediterranean countries, especially for the richer ones, although their lands will be more arid, there will be still water for drinking, house use and drip irrigation, like Israel. And for Dubai etc, well saudis still earn money from religious tourism but they have to spend very carefully, and Dubai had increased its non petroleum based economy. For Oman and yemen well perhaps rainfall increase in these countries, if not they have to change and use their tourism and mining potential be more careful when exploiting their fisheries etc but nearly non of these countries has an important agricultural activity, perhaps yemen has some but still a decrease in barely exist rainfall will not affect much these mostly rich countries. For Israel if desalination and very cheap energy technologies will not improve enough, it will be very devastating. For Egypt I have no idea what will happen to nile and also even a slight increase in sea levels will ruin most important areas in the country. For Algeria Tunisia and Morocco, probably millions of refugees will flow from these countries to europe but I have not a clear idea. I am not against the measures against climate change but I wonder and I want to watch more realistic forecasts with reasons.

IF the earth temperature increased 4°C, the Sahara desert would be a garden again.

Look what happened millions of years ago, the earth warmed, the ice began to melt, and new life, life that we see today, but before the ice, the earth was formidable, hostile sub tropical very hot, terrarium type environment, it will eventually be that again once all the ice left has completely melted, maybe 10, 000 years from now is my guess, perhaps ten times that, it depends alit on volcanoes, they would cause rapid heating, or a meteor impact, asteroid, but not us microdust organisms . That’s just a big lie and global wealth transfer scam .

Go vegan, problem solved and anger the owners of all these news corporations at the same time lol.
