Four BILLION people could die by 2050 due to climate change

[SamuelTheThird]

This staggering news went under the radar. This is not some fly-by-night group stating this.

Without urgent action to accelerate decarbonisation, remove carbon from the atmosphere and repair nature, the plausible worst-case hit to global economies would be 50% in the two decades before 2090, the IFoA report said.

At 3C or more of heating by 2050, there could be more than 4 billion deaths, significant sociopolitical fragmentation worldwide, failure of states (with resulting rapid, enduring, and significant loss of capital), and extinction events.

1. The Blue Whale very well might go extinct because their food called krill needs cold water and the

City of New Orleans is gonna go under water.

9. In 1856 and in Germany in 1862

They ran experiments that showed the more CO 2 you had in of gas the more heat that
body of gas would hold. It is now one of the universal gas laws and it has never been
disproven once.

11. thats why i keep supplies in my attic.

i will be here, dead or alive.

2. Maybe the problem will go away if we ignore it harder?

That seems to be the prevailing attitude.

[Volaris]

4. Its more likely the problem will be self-correcting..

4 billion dead in less than a century, will put a crimp on the demand side of the fossil fuel equation that's for damn sure.
Not pretty for any of us, but the environment and the planet, WILL find a way to outlive this problem we have created...it doesn't much care if we're still there on the other side or not.

3. We are lousy stewards of this planet. Unfortunately a lot of those who are responsible will not be here

to reap the "rewards" of their actions or inactions.

5. I fear the world will respond with authoritarianism

The upheaval and turmoil will give authoritarians issues to run on like immigration.

Mass migration because of climate change is already occurring and it's almost never discussed as such. In the US, much of the immigration we've seen at the Southern border is partially due to climate change. Subsistence farming in the mountains of Central and South America has become rarer because climate change has shutdown some systems that brought nutrients to those regions. This prompted millions of people to leave small towns and head to the cities looking for work thus taxing the infrastructure in those cities and overcrowding them leading to higher crime and gangs that families flee by heading North. We're seeing the same thing in Europe. It's not going to slow down.

6. It is the natural consequence of how we treat our planet. The

bad part is that many of those people will be from national that didn't contribute much or at all to the situation.

8. What can you expect from a species

that shits where it eats? The only place where we can live.

[rampartd]

10. 4 billion people could die by 2050 due to old age.

or from the unvaccinated childhood diseases.

the less populated earth should be a very nice place for the survivors.

i plan to stay in new orleans until the gulf of mexico reaches my door step.

[AloeVera]

12. Pretty sure they weren't talking about deaths from old age.

[Another Jackalope]

14. Given the current death rate, only 1.5 billion would die of natural causes.

The other 2.5 billion would be what are called "excess deaths" over and above the average expected number.
The birth rate will plunge as well, so there won't be as many replacement births.

It's going to be an "interesting" couple of decades.

[BannonsLiver]

13. You know who I bet won't be one of the 4 billion?

I’ll show myself out.

15. No realistic plan in place to avoid this scenario

Sandy Trust, the lead author of the report, said there was no realistic plan in place to avoid this scenario.

He said economic predictions, which estimate that damages from global heating would be as low as 2% of global economic production for a 3C rise in global average surface temperature, were inaccurate and were blinding political leaders to the risks of their policies.

The climate risk assessments being used by financial institutions, politicians and civil servants to assess the economic effects of global heating were wrong, the report said, because they ignored the expected severe effects of climate change such as tipping points, sea temperature rises, migration and conflict as a result of global heating.

“[They] do not recognise there is a risk of ruin. They are precisely wrong, rather than being roughly right,” the report said.

There has never been a realistic plan to avoid this scenario. All talk otherwise is simply whistling past the graveyard. Don't look up.

Estamos tan jodidos.
