first you need to learn greenhouse effect

Results depend on how fast we can stop it. If we don't do anything reptiles will rule the world again.

depends on how much we heat up the planet

>Even if our energy was low carbon, global warming would continue.

If we stop greenhouse gas emissions global warming will slow down and stop. If we fail and keep burning fossil fuels like mad warming will happen even faster. All coastal cities may be permanently flooded. Bad things will happen.

that graph is still very optimistic, no action would end up with 8° or more and unhealthy amounts of CO2 in atmosphere

But we can stop carbon emissions for planes easily. renewable jet fuel exists. It just needs to be used more.

There are nations with 100 % renewable energy. Works like a charm. No worries

If we keep doing what we do the result will be worse then nuclear war.

this is what future looks like

actually we should have acted at least 40 years ago, but if we start now we might still be able to avoid some of the worst effects

This is the official scientific outline. They have done research on the effect per degree of warming total ecological collapse will only happen at 4 degrees of warming. reduction in biodiversity will happen increasingly from1 degree of warming upwards exponentially.

It's absolutely not collapsing though, not even close. Saying things like this is why most people don't take it seriously anymore they either think "it's not worth it anyway we are already fucked, why bother". Or people stop trusting information because everyone and their dog is exaggerating for more funding.

The real official global guidelines as seen in the Paris Climate Accord have the 4 degrees warming as the absolute limit after which the total ecosystem collapses.

>Most Countries
>As of February 2019, 194 states and the European Union have signed the Agreement. 184 states and the EU, representing more than 87% of global greenhouse gas emissions, have ratified or acceded to the Agreement, including China, the United States and India, the countries with three of the four largest greenhouse gas emissions of the UNFCC members total (about 42% together).
>On August 4, 2017, the Trump administration delivered an official notice to the United Nations that the U.S. intends to withdraw from the Paris Agreement as soon as it is legally eligible to do so.[77] The formal notice of withdrawal cannot be submitted until the agreement is in force for 3 years for the US, in 2019.[78][79] In accordance with Article 28, as the agreement entered into force in the United States on 4 November 2016, the earliest possible effective withdrawal date for the United States is 4 November 2019. If it chooses to withdraw by way of withdrawing from the UNFCCC, notice could be given immediately (the UNFCCC entered into force for the US in 1994), and be effective one year later.

TL;DR: Literally every country on the planet (even north korea) have signed into the accord. USA didn't leave (yet)

if we act now it's not this bad, but if we wait for another generation we are in deep shit

don't you watch news?
- worst wildfire in history
- record drought
- strongest hurricane ever
- highest flood
- biggest heatwave
- etc.
it's getting worse every year and it will go on like this if we don't stop climate change

>>10280814
it's not just sea level rise

1. climate change is real
2. if we don't stop it mankind will cease to exist
3. the sooner we stop it the better
4. please have a look at this picture

If we just go on like this we don't need to worry. Civilisation breaks down. 100% of population will die. Extinction is unavoidable.

We could still stop this madness, but there are far to many fossil industry shills and far to many deniers.
