Some Super Important Things to Understand About the Planet's Temperature
Updated: Aug 18, 2021
Here is an excerpt from "Some super important things to understand 🌎" by Ryan Hagen, which was super eye-opening for us at Tirtanium. Ryan explains that at current trajectories the most likely temperature rise by 2050 is +2C. Most worryingly for us, according to a BAPENNAS (Ministry of National Development Planning) report, at this level of temperature increase, most Indonesian cities will be underwater... what a sobering reminder that the time to consume the planet's resources more responsibly is NOW (not 5-years down the road).
Big Picture: Where society stands
The world is about 1.2°C (2.16°F) hotter today than it was before the industrial revolution.
Every country in the world has agreed to limit warming to 2°C at most, with a goal of 1.5°C thanks to the heroic efforts of the island nations who know their countries need "1.5 to stay alive".
After that, in 2018, the IPCC (who aggregate the best and latest climate science) released a report comparing 1.5°C and 2°C. It became blatantly obvious that there's nothing safe about 2°C and the world really needed to aim for 1.5°C.
To put it simply, the less the planet heats up, and the faster we eliminate greenhouse gas emissions, the less suffering, death, and destruction there will be.
Not to mention, minimizing heating also minimizes the chances of runaway warming...which would be unimaginably devastating for civilization.
Society continues to march recklessly in the wrong direction and has already left the safety of 4 out of 9 planetary boundaries that keep everything stable (refer to image below - Green = safe; Yellow = danger zone; Red = Extremely high risk of irreversible tipping points.)
We highly recommend watching Johan Rockström and David Attenboro's "Breaking Boundaries" on Netflix for an eye-opening deep-dive on this chart.
As you can see, the most likely temperature rise by 2100 right now is 3.2°C (no thank you). And there's only a 5% chance of greater than 5°C temperature rise. As well as a 5% chance of keeping warming under 2°C, and a 1% chance of keeping warming to 1.5°C.
The UN emissions gap report says we need to triple our current efforts to have a chance at keeping warming under 2°C. And increase efforts by 5x for 1.5°C.
Now, it's all well and good to say we're at 1.2°C now and need to limit warming to 1.5°C. But this also needs to be translated into something we can actually wrap our heads around.
