Climate Change Impact Assessment

The video discusses the critical target of limiting global temperature rise to 2 degrees Celsius. Despite halting emissions, temperatures could still rise by 1 degree, leading to severe environmental impacts such as glacier loss, freshwater scarcity, and ecosystem collapse. Polar regions are warming faster, causing self-reinforcing ice melt. A 2-degree rise could result in catastrophic consequences, including mass extinctions and significant sea level rise. To avoid this, carbon emissions must be limited to 2.9 trillion tons, with only 1 trillion tons left to use. At the current rate, this limit will be reached in 21 years.
