Climate Change Is a Planetary Emergency — How Can We Avert Disaster?

Climate Change Is a Planetary Emergency — How Can We Avert Disaster?. Ecowatch

By World Economic Forum

While politics continue to cripple efforts to fight the planetary emergency, the science remains as unequivocal and irrefutable as ever.

We have already crossed a number of ‘tipping points’ in the Earth system; vital thresholds beyond which irreversible and catastrophic consequences for all life on this planet will ensue. The impacts of climate change and ecological destruction are more severe and are manifesting themselves earlier than many scientific predictions in previous decades had foreseen. Without major interventions, the risks will soon reach a critical stage.

For 10,000 years, human civilization has grown and thrived because of the Earth’s remarkable climate stability and rich biological diversity. Astonishingly, every year since the Industrial Revolution, land-based and ocean ecosystems have absorbed close to half of all our emissions from fossil-fuel burning. That’s because of the climate, and the natural ecosystems which regulate it and all life on earth, are inextricably linked. In fact, species diversity and ecosystems integrity play a fundamental role in regulating the climate, water cycles, carbon sequestration and food production.

Without nature’s ability to absorb and store our GHG emissions, we would have already exceeded 2 C of warming, with potentially disastrous consequences decades ago.

The simple fact is, we don’t know how to reconstruct the cryosphere, the hydrological cycle, the rainforests, coral reefs and other life-support systems on Earth. Once the emergency fully manifests, it will simply be too late to reverse the breakdown.

Collapse will cease to be something we can control. Collapse will no longer be a mere hypothetical; it will be a near certainty. Put bluntly, this is the greatest existential risk facing modern human civilization.

It is, without doubt, our patterns of economic growth, development, production and consumption which are pushing the Earth’s life-support systems beyond their natural boundaries. We depend so fundamentally on these ecosystems. And yet it is we who are the very drivers of their demise. It is we who are pushing the systems which support life on Earth beyond their natural boundaries.

It is we who are causing severe changes in weather patterns and wreaking untold destruction in the shape of wildfires from the Amazon to Australia, and violent storms from Mozambique to Barbados, to name but a few. And while a great majority of governments and corporations continue to twiddle their thumbs in what amounts to outright denial of the facts, the risks of collapse. Read more…
