Fire crews are closely watching the Palisades Fire in Mandeville Canyon, Los Angeles. This situation underscores the pressing climate issues as global leaders gear up for the annual United Nations climate talks in Belem, Brazil. It’s over ten years since the historic Paris climate agreement, but experts say climate change is happening faster and with more severity than we expected.
Since 2015, we have seen a slight improvement—like a reduction of more than one degree Celsius in future warming predictions. However, scientists warn that the damage from climate change is escalating quicker than our efforts to move away from fossil fuels. Johan Rockstrom, head of the Potsdam Institute for Climate Research, emphasizes that leaders need to face this reality. The harmful effects of warming are hitting us faster than we thought.
At these negotiations, former U.N. climate chief Christiana Figueres expressed mixed emotions. She acknowledged some progress, but the gap between what we’ve achieved and what we need to do is growing. Inger Andersen, the U.N. Environment Programme’s Executive Director, painted a dire picture when she stated, “We’re sort of sawing the branch on which we are sitting.”
As temperatures rise, the past ten years have seen some of the hottest years on record. According to the European climate service Copernicus, this year is likely the second or third hottest ever recorded. Since 2015, the world has faced many extreme weather events, from scorching heat waves in areas like the Pacific Northwest and Siberia to destructive hurricanes. In the U.S. alone, there have been 193 weather-related disasters costing over $1 billion each.
Amid these challenges, we are seeing positive changes in renewable energy. In 2015, only 500,000 electric vehicles were sold worldwide. Last year, that number skyrocketed to 17 million. Renewable energy is becoming cheaper than fossil fuels in many places, with 74% of global electricity growth coming from green sources last year.
However, the future warming projections remain concerning. Earlier U.N. estimates suggested we could be heading toward nearly 4 degrees Celsius of warming. Now, the trend seems to be around 2.8 degrees, still far above the ideal goal of keeping it under 1.5 degrees Celsius.
The Bezos Earth Fund reports that while some climate progress is visible, it isn’t nearly enough to meet the Paris goals. Meanwhile, greenhouse gas levels are still rising. In developing countries, emissions have surged—up by 15.5% in China and 26.7% in India—while some developed nations have seen reductions. This trend is troubling, especially since wealthier individuals’ emissions have increased since 2015, while poorer communities have reduced theirs.
As world leaders gather to tackle climate change, we face a complex challenge. The gap between technological advancements in sustainability and the ongoing degradation of our planet is vast. Yet, it also opens up opportunities for meaningful action in the fight against climate change.
