We are still learning how exactly the Earth reacts to increased CO2 and other greenhouse gases. We know it leads to warming seas which are melting the North and the South Poles, rising and starting to swallow entire coastal areas in the US and elsewhere, as the New York Times article documents.

If nuclear warfare is believed to be somewhat controlled, then climate change is now the greatest threat.

We need to support our future instead of undermining human survival. Let's do it.

Carbon negative power plants can provide energy while they overcome poverty and change economic values in the right direction.

After denial comes anger and finally, acceptance.
