The Paris Agreement 2015 is the latest international treaty on climate change.
Quoted from wikipedia
The Paris Agreement's long-term temperature goal is to keep the rise in mean global temperature to well below 2 °C (3.6 °F) above pre-industrial levels, and preferably limit the increase to 1.5 °C (2.7 °F), recognizing that this would substantially reduce the effects of climate change. Emissions should be reduced as soon as possible and reach net-zero by the middle of the 21st century. To stay below 1.5 °C of global warming, emissions need to be cut by roughly 50% by 2030. This is an aggregate of each country's nationally determined contributions.
According to the 2020 United Nations Environment Programme (UNEP), with the current climate commitments of the Paris Agreement, global mean temperatures will likely rise by more than 3 °C by the end of the 21st century.
Countries determine themselves what contributions they should make to achieve the aims of the treaty. As such, these plans are called nationally determined contributions (NDCs).
In 2021, a study using a probabilistic model concluded that the rates of emissions reductions would have to increase by 80% beyond NDCs to likely meet the 2 °C upper target of the Paris Agreement, that the probabilities of major emitters meeting their NDCs without such an increase is very low. It estimated that with current trends the probability of staying below 2 °C of warming is 5% – and 26% if NDCs were met and continued post-2030 by all signatories.
The message from the above quotations is
1. The Paris Agreement is an attempt to limit climate change effects by keeping global mean (average) temperatures below 1.5C or 2C.
2. We are likely looking at global temperature rises between 2C and over 3C by the end of the century.
We are currently at 1.1 or 1.2C global mean temperature above pre-industrial levels. There are extreme climate events now never mind at 1.5, 2 or over 3C.
2022 saw record-breaking heat in UK while there were heatwaves and vast wildfires in North America, record-breaking temperatures and huge wildfires across France and Western Europe, huge drought followed by severe flooding in Pakistan, repeated flooding in Eastern Australia and currently East Africa is suffering the worst drought in decades.
We are in a climate crisis at 1.2C. The crisis is now.
The main cause of global warming is the use of fossil fuels. The best response to the climate crisis is to stop the use of fossil fuels as much as we possibly can and to transition to renewable sources of energy instead. This would also involve a programme of insulation to reduce the use of fossil fuels.
Politicians worldwide are neglecting to address the climate crisis in any meaningful way. The protest group Just Stop Oil is calling for no new development of fossil fuels. Grant Shapps, UK's Secretary of State for Business, Energy and Industrial Strategy is so totally out of touch that he's not even familiar with Just Stop Oil's objectives: “I’ve no issue with people arguing for lower levels of petrol, gas or whatever other thing they want to campaign for usage, that is fine, that is one thing. But don’t go disrupting other people’s lives - it’s unacceptable, it’s illegal!”, the Business Secretary said.
Young people particularly should get active opposing climate destruction because it's fekking their futures and otherwise they're just going to keep on getting totally disregarded, shat on. Extreme weather events at 1.2C are so serious, 3C may well lead to extinction and next to nothing is being done to prevent it.
