Pt. 3: The Paris Agreement
The 2015 Paris Climate Accords is an international (almost global) treaty about the climate crisis.

Basically the whole world agreed to limit global heating well below 2°C above pre-industrial average temeratures - ideally below 1,5°C.
That would limit the impact of the climate crisis.
Climatejustice groups usually invoke the 1.5°C limit of the climate agreement.

In 2020 we were already at 1.25°C of global heating and most scientists agree that it is near impossible to stay below the 1.5°C limit now.

But there is still hope: Every policy and law put into place that helps limit the global heating even by a fraction of a degree saves lives and livelihoods.

Pt. 2: The Greenhouse effect
Very basically: Greenhouse gases are better at reflecting radiated heat than at reflecting sunlight, which is why more greenhouse gases lead to about the same amount of sunlight hitting the earth's surface, but more of the then radiated heat staying in the earths atmosphere.

Without a greenhouse effect the earths surface temperature would be about −18 °C (−0.4 °F), so the planet would be uninhabitable by humans.

Too much greenhouse gas however increases the earths temperature above a temperature, where its healthy and comfortable to live on earth as humans.

We know the earth is warming, as we established in the previous post.
Let's next find out how we know that this global heating is human made - or rather capitalism made.

Today: Global Heating.
From 0 a.d. to 1880 temperatures were relatively stable. Afterwards they rose drastically to now almost 1,5°C above the average temperatures before.

We know the temperatures from before 1880 because of tree rings, corals, and ice cores.
The much more important temperature measurements we know because of something called a #thermometer.

Thermometers were not a single invention, but a development. Many however credit Hero of Alexandria (10 a.d. to 70 a.d.) with the invention.
In 1880 thermometers were already very precise and reliable.
