Why is the goal 2°C by 2100 copilot

Indeed, you're still here posting nonsense. Ivanka failed as a solar plant. Pretty much every wind farm is failing. The only true green energy systems are hydroelectric. But even there you have to drown entire regions to build up the water supply.

But keep on telling lies, you help us with every one you tell.

My, but that is one stupid statement. The tipping points that will do damage to our civilization did not do damage to a civilization that did not exist at that time is hardly a valid argument. Already we are seeing the effects of the increase in temperature in extreme weather events, increased droughts, and wildfires.

How many "tipping points" must we pass before you admit that your entire screed is a lie?

I think we have now passed at least 7 of them.

The 2°C climate goal (aiming for 1.5°C) is a threshold set by the IPCC and the Paris Agreement to avoid severe, irreversible damages. Exceeding this limit by 2100 risks triggering tipping points like rapid ice sheet collapse and massive biodiversity loss, leading to extreme sea-level rise, severe heatwaves, and food shortages. [1, 2, 3, 4]
Key Reasons for the 2°C Limit:

• Preventing Irreversible Tipping Points: Scientists warn that a 2°C rise could trigger climate tipping points, such as the total collapse of the Greenland and West Antarctic ice sheets. Once triggered, these processes may become unstoppable, causing significant sea-level rise over centuries.
• Limiting Catastrophic Weather: Beyond 2°C, the intensity and frequency of droughts, extreme heatwaves, and severe weather events increase dramatically, according to the IPCC report highlighted by Active Sustainability.
• Protecting Ecosystems: A 2°C increase would cause significant damage to ecosystems, including the potential death of almost all tropical coral reefs by mid-century, says research cited in this Active Sustainability article.
• Ensuring Human Security: A 2°C increase is projected to cause major disruptions to food and water security, economic stability (e.g., loss of 11% of global GDP), and human health, according to data analyzed in this article and this report from unclimatesummit.org.
• Scientific consensus & Feasibility: While 1.5°C is considered safer, 2°C was historically set as the maximum "guardrail" to avoid the most dangerous impacts. The Paris Agreement aim is to keep warming "well below" 2°C, say Climate Action Tracker and BBC Science. [1, 2, 3, 4, 5, 6, 7]

Current Outlook:
While the target is 2°C, current global policies and emissions put the world on track for a likely increase between 2.1°C and 2.9°C, which would exceed the goal as discussed in this Wikipedia article. [1]
