Climate Assessment Reports

This hugely important report from 12 US government agencies was released at a time when people were preoccupied with Thanksgiving holidays, some believe, in order to minimise its  impact. It has dire conclusions about the impact of climate change on the US economy but appears to remain firmly within the ‘economic growth is good’ paradigm.

“Scientists have understood the fundamental physics of climate change for almost 200 years. In the 1850s, researchers demonstrated that carbon dioxide and other naturally occurring greenhouse gases in the atmosphere prevent some of the heat radiating from Earth’s surface from escaping to space: this is known as the greenhouse effect. This natural greenhouse effect warms the planet’s surface about 60°F above what it would be otherwise, creating a habitat suitable for life. Since the late 19th century, however, humans have released an increasing amount of greenhouse gases into the atmosphere through burning fossil fuels and, to a lesser extent, deforestation and land-use change. As a result, the atmospheric concentration of carbon dioxide, the largest contributor to human-caused warming, has increased by about 40% over the industrial era. This change has intensified the natural greenhouse effect, driving an increase in global surface temperatures and other widespread changes in Earth’s climate that are unprecedented in the history of modern civilization.”

Here  is a short introduction by a journalist to the report.

A similar report for Europe Climate Impacts on Economy (European Commission)- impacts examined: Coastal floods; River floods; Droughts; Agriculture; Energy; Transport; Water resources; Habitat loss; Forest fires; Labour productivity; Mortality due to heatwaves.
