3) "What is it that takes Earth back to 1.5°C after overshoot? What the climate models show is that once GHG emissions are turned off, temperatures will gradually decline, as CO2 is absorbed in the biosphere on land and in the ocean. Is this likely to happen? The simply answer is, we do not know"

2) "We will be exceeding the likely threshold when tipping elements like all coral reef systems, the great Ice sheets (GIS/WAIS) and permafrost thawing, shift state from "good" to "bad". Will these tipping elements cope with a period of overshoot? We do not know. It will be a very risky period."

1) "We know with 100 % certainty that this means rising frequency and strength of extreme events. So, the message to the world is this "buckle up" because we are inevitably facing 30-40yrs of rising climate damages to societies across the world. It will even at best - get worse before it gets better."

"The best we can accomplish, is 1.5°C with overshoot. The reason for this is that we have already loaded so much energy/heat into the Earth system, that even if we stopped all emissions today, we are already committed to warming exceeding 1.5°C"—Prof Johan Rockström

If aviation were a country, it would be the world’s sixth-biggest emitter, falling after China, the US, India, Russia, and Japan.
Reminder: The CO2 emissions from these 23,000 flights will last in the atmosphere for 300-1,000 years.

This tells you *everything* you need to know about how serious the fossil fuel industry is about the clean energy transition.
“The Godfathers of climate chaos – the fossil fuel industry – rake in record profits and feast off trillions in taxpayer-funded subsidies.”—Antonio Guterres

This is *absolutely* the right call:
“I urge every country to ban advertising from fossil fuel companies.
“And I urge news media and tech companies to stop taking fossil fuel advertising.” — Antonio Guterres

Here I am sounding like a broken record again.
There is no evidence of an emergency “Covid-like” response to emission reductions.
As a result, we need to prepare physically, mentally and emotionally for a world at 2° within the next 20 years.

2024 is not just an election year. It is THE election year.
64 countries—representing a combined global population of about 49%—are holding national elections, the results of which will prove massively consequential as we head deeper into the #ClimateCrisis
#Vote to keep fossil fuels in the ground!

I don’t think any of us really understand how quickly collapse can happen:
> About 85% of the country expected to see highs of at least 40°C
> Almost 40% of the country’s dams below 20%
> 40% are between 20 and 50%.
> Mexico City (Population 22.51 million) forced to reduce water supply as reservoirs that feed city dry up.
> Stores running out of mineral water.

"I don't say this lightly - but the floods in
#PortoAlegre, #Brazil, are looking comparable to what Katrina did to New Orleans in 2005 -- massive evacuations, water & power outages, key infrastructure damaged, parts of city, possible long-term consequences."—Brian Winter

These instrument readings serve as a stark reminder of our current trajectory.
They not only reflect our past and present actions but also foreshadow a future dictated by them - ie a world that has heats to between 2.1-3.5ºC
It is only when these figures begin to reverse that we can confidently say our efforts to change course are effective.
Pay attention to the instruments!
