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

We have to remove the CO2 that the industrial economy has already emitted, which otherwise will remain in the atmosphere for hundreds of years and alter the Earth's climate irreversibly. It is possible to do this.

While denial leads to certainty, it is only the certainty of death. This is true for individuals and also for civilizations.

To survive, humans need food, water, and air. Yet biodiversity, the Earth's bodies of water, and the planet's atmosphere are all under threat.

The sun is the source of all energy on planet Earth and we cannot experiment with our only energy source.

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.

Geoengineering means changing the Earth's fundamental large-scale processes.
