Changing the world's oceans to increase their uptake of CO2, as other geoengineering solutions propose, is equally dangerous, as the increased resulting acidity of the oceans kills tiny crustaceans, such as krill, that are the basis of the pyramid of life on the planet as we know it.

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

Signs of a poorly understood but treatable house fire requires action, not inaction.

The new markets that arise from ecological constraints will dominate the 21st century economy, and so will markets for knowledge.

After denial comes anger and finally, acceptance.

We know little of the consequences of the geoengineering process, such as spraying particles into the atmosphere that shade the planet from the sun's rays and could decrease its temperature. But this process is how dinosaurs disappeared from the Earth about 60 million years ago, by particles spewed by a volcano or a giant meteorite impact, and our species could follow suit.

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