Showing results for "Climate Change" in United States

Burning fossil fuels will cause catastrophic global warming: this is what top American oil executives were told by scientists in 1959. But they ignored that warning. Instead, they developed one of the biggest, most polluting oil sources in the world—the oil sands in Alberta, Canada. As investigative journalist Geoff Dembicki reveals in this explosive book, the decades-long conspiracy to keep the oil sands flowing into the US would turn out to be one of the biggest reasons for the world's failure to stop the climate crisis.

For decades, climate scientists have been warning of the dangerous effects of the emission of greenhouse gases into the atmosphere. They have urged a variety of measures that might prevent some of those disasters they claim to foresee. Others deny the reality of human-caused climate change and believe that scientists' warnings about the impact are exaggerated. Speeches are presented from both sides of the issue.

The 21st century unleashed unprecedented changes across the globe—to its climate, to the demographic makeup of its nations, and to the very nature of allegiance in the digital age. With its global influence waning, America must reevaluate its approach to globalization if it wishes to remain a leader.

Climate change is today's news, but it isn't a new phenomenon. Centuries-long cycles of heating and cooling are well documented for Europe and the North Atlantic. These variations in climate, including the Medieval Warm Period (MWP), AD 900 to 1300, and the early centuries of the Little Ice Age (LIA), AD 1300 to 1600, had a substantial impact on the cultural history of Europe.
