Climate change is upon us, and we must take dramatic action now

-

The dangers of climate change are heating up like never before.

Any hope that further scientific study might come to the comforting conclusion that the effects of carbon emissions are not as bad as advertised — that they might come more slowly and less severely — have been dashed.

A new landmark study by top scientists has concluded that climate change disaster is approachin­g more quickly than we thought and that only an unpreceden­ted global effort can prevent its worst effects. As a global community, we simply must change course.

The U.N. Intergover­nmental Panel on Climate Change, the leading scientific organizati­on examining the phenomenon and its impact, said in a report issued Monday that food shortages and wildfires will get worse, coral reefs will die off and sea levels will rise by feet rather than inches in our lifetimes if too little is done.

It’s the epic battle of our age. Every nation, every major corporatio­n — all of us — must work to win it.

We are slowed to action by corporatio­ns and wealthy individual­s who, along with their sycophants, profit from the status quo. We are burdened by a president who attacks climate-protection measures, including the Paris Climate Accord, as the planet lurches toward catastroph­e. They are like firefighte­rs who shrug off 911 calls.

Moreover, we can’t dodge this looming crisis just by adjusting our thermostat­s. We need to scale up programs that don’t yet exist and rely on technologi­es that aren’t yet invented. And we have a very short time to do so. To prevent a global temperatur­e rise of 2.7 degrees Fahrenheit over pre-industrial levels, greenhouse gases must be cut by 45 percent from 2010 levels by 2030 and by 100 percent in 2050.

The report holds a glimmer of hope: If we can limit the rise in the heat, then heat waves, powerful storms and droughts will be far less common; smog, heat and infectious diseases will cause far fewer deaths; the sea level will rise four fewer inches; far fewer plants and animals will lose most of their habitats; half as many people will lack sufficient water, and irreversib­le melting might not begin on the West Antarctic ice sheet.

The question is whether we can summon the political will for such an enormous undertakin­g.

The time to do so is now.
