Climate engineering-which could slow the pace of global warming by injecting reflective particles into the upper atmosphere-has emerged in recent years as an extremely controversial technology. A leading scientist long concerned about climate change offers a proposal for an easy fix to what is perhaps the most challenging question of our time.
After decades during which very little progress has been made in reducing carbon emissions we must put this technology on the table and consider it responsibly.

|The Truth about Climate Change
This is a two-part documentary series presented by David Attenborough, about global warming and the surrounding controversy.
|What to Know about Geoengineering
What to do about the excess CO2 in our atmosphere that will remain for hundreds of years - even as we transition to renewable energy? The impact on Earth's climate is already obvious and it will continue.
|Ethics of Climate Change and Climate Engineering
Over the last 30 years predictions of climate change as a threat to individuals, societies and nations have changed from possibilities to realities.
|Contemporary Climate Change as Seen Through Measurements
Ralph Cicerone reviews up-to-date data on temperatures of air and water, rates of ice losses and of sea-level rise and illustrate the driving forces of greenhouse gases in an energy-balance model of Earth.
|Climate Change: The Evidence and Our Options
Lonnie Thompson provides insight into the convincing evidence of climate change provided by glaciers and polar ice-caps, and the implications that inaction in the face of this rapid change will have on societies on a global scale.
