What were the key outcomes and concerns regarding international climate commitments made at COP26?

COP26 featured striking art installations, like Tuvalu's polar bears in life vests and a penguin in a noose, highlighting the desperate situation of climate-vulnerable nations. World leaders made significant pledges including reducing coal and methane emissions and ending deforestation, which could theoretically limit global warming to 1.8 degrees if fully implemented. However, this falls short of the critical 1.5-degree target needed to prevent catastrophic consequences. The situation becomes more concerning when considering nations' poor track record on climate promises. For instance, rich countries pledged $100 billion annually to help developing nations by 2020 at COP15 twelve years earlier, yet they remain far from meeting this commitment, raising serious doubts about whether current pledges will be fulfilled.
