We've Already Built too Many Power Plants and Cars to Prevent 1.5 °C of Warming:
In a [...] paper published in Nature today[*], researchers found we're now likely to sail well past 1.5 ˚C of warming, the aspirational limit set by the Paris climate accords, even if we don't build a single additional power plant, factory, vehicle, or home appliance. Moreover, if these components of the existing energy system operate for as long as they have historically, and we build all the new power facilities already planned, they'll emit about two thirds of the carbon dioxide necessary to crank up global temperatures by 2 ˚C.
If fractions of a degree don't sound that dramatic, consider that 1.5 ˚C of warming could already be enough to expose 14% of the global population to bouts of severe heat, melt nearly 2 million square miles (5 million square kilometers) of Arctic permafrost, and destroy more than 70% of the world's coral reefs. The hop from there to 2 ˚C may subject nearly three times as many people to heat waves, thaw nearly 40% more permafrost, and all but wipe out coral reefs, among other devastating effects, research finds.
The basic conclusion here is, in some ways, striking. We've already built a system that will propel the planet into the dangerous terrain that scientists have warned for decades we must avoid. This means that building lots of renewables and adding lots of green jobs, the focus of much of the policy debate over climate, isn't going to get the job done.
We now have to ask a much harder societal question: How do we begin forcing major and expensive portions of existing energy infrastructure to shut down years, if not decades, before the end of its useful economic life?
Power plants can cost billions of dollars and operate for half a century. Yet the study notes that the average age of coal plants in China and India—two of the major drivers of the increase in "committed emissions" since the earlier paper—is about 11 and 12 years, respectively.

The planet's overpopulated and it's going to kill us all? We need to bring in more migrants! More of them! And make sure that they all have enough cars and power plants to bring them up to your standard of living or else there won't be social justice! And you get to pay for it! You get to pay for the migrant feeding programs! You get to pay for the migrant breeding programs back in Africa to make more migrants! And you are already paying for this propaganda to shame you into paying for it! And if you say it's a bad idea we'll call that "hate speech" and send the police after you and fine you and take your house and car! And you pay for that too!

Hi racist fuckwit, enjoy being a stupid lonely piece of crap looked down upon by just about every human being. I'm praying for your soul.

Global warming causes more migration. If you don't want more migrants, fight against global warming.

Hey dipshit. Whether migrants come to live in your back yard or stay in their country of birth, the net population of the planet stays the same. Or has rapid migrant-phobia now extended to immigrants from Proxima Centauri?
You want to kill people to save the planet? Start with yourself.
