Warning of 'Existential Threat' to Humanity, UN Chief Says Climate Change Moving Faster

In the wake of worldwide #RiseForClimate protests last September, which brought more than 250,000 people into the streets to call for bolder action to address the global crisis, the U.N. chief declared, "If we do not change course by 2020, we risk missing the point where we can avoid runaway climate change, with disastrous consequences for people and all the natural systems that sustain us."

Researchers from around the world continue to raise alarm about the dire consequences of burning fossil fuels that generate planet-warming emissions.

Recent reports have detailed how the global climate crisis makes extreme weather more likely; how accelerated Arctic warming is stalling summer weather over North America, Europe, and Asia, which could lead to "very-extreme extremes"; and the precise threats to certain regions—such as California, which faces a future of dangerous heat waves, devastating wildfires, intense rain events, and costly sea-level rise.

The "Hothouse Earth" study provoked a flood of "breathless headlines" [in August 2018] for its warnings of a possible domino effect of climate feedback loops that could lead to runaway global warming—though at least one of its co-authors optimistically posited after all of the media attention that "people will look back on 2018 as the year when climate reality hit."

"Scientists have been telling us for decades. Over and over again. Far too many leaders have refused to listen. Far too few have acted with the vision the science demands," Guterres noted. "Dear friends, we know what is happening to our planet. We know what we need to do. And we even know how to do it. But sadly, the ambition of our action is nowhere near where it needs to be."

Calling the Paris climate agreement the "bare minimum," Guterres pointed out that states who support the accord—every nation on the planet but the United States, thanks to President Donald Trump's decision to bail on it last year—are failing to live up to its inadequate goals.

"We have the moral and economic incentives to act. What is still missing—still, even after Paris—is the leadership, and the sense of urgency and true commitment to [a] decisive multilateral response," Guterres concluded. "Our fate is in our hands. The world is counting on all of us to rise to the challenge before it's too late."
