Abrupt Impacts of Climate Change: Anticipating Surprises
Climate is changing, forced out of the range of the past million years by levels of carbon dioxide and other greenhouse gases not seen in the Earth’s atmosphere for a very, very long time. Lacking action by the world’s nations, it is clear that …
Linkages Between Arctic Warming and Mid-Latitude Weather Patterns: Summary of a Workshop
The Arctic has been undergoing significant changes in recent years. Average temperatures are rising twice as fast as they are elsewhere in the world. The extent and thickness of sea ice is rapidly declining. Such changes may have an impact on …
Climate Intervention: Reflecting Sunlight to Cool Earth
The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those …
Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration
The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of …
