How to talk to an ostrich
“It’s Just The Volcanoes!"
How we know, for sure, that “It’s Us” who are changing Earth’s climate.
“CO2 Was Way Higher In The Past.”
Today’s levels of CO2 are unprecedented in human history. At least for 400,000 years, almost certainly for 800,000 years and probably for 8 million years. But this time we’re here to “take the heat.”
"Only tree-huggers think climate change is real."
Not exactly: the Pentagon, mandated to look decades ahead for threats to the nation's security, started factoring climate change into strategic doctrine with the 2012 Quadrennial Defense Review, the QDR. Admiral David Titley, director of Task Force Climate Change and former Oceanographer of the Navy, explains why the Pentagon accepts the reality of climate change.
“We Can’t Afford A Clean Energy Economy.”
Yes, we can—we’ve done it before: the example of the revolution in public health that replaced chamber pots with sewers and clean water.
“Earth’s Climate Changes Gradually… We Can Easily Adapt.”
Maybe, maybe not… because sometimes climate goes over the edge, and quickly. Perhaps we’d better take out some insurance.
“We Don’t Know Enough to Say for Sure…”
Yes, we do. Earth’s climate may be a jigsaw puzzle, but the big picture is already clear.
"Global Warming Stopped in 1998!"
Geoscientist and climate expert Richard Alley connects the dots of temperature to show the difference between short-term trends and long term direction. He uses milestones of his own life to make this key argument personal and memorable.
"Who says CO2 heats things up?"
Some seem to think that the heat-trapping properties of carbon dioxide are exaggerated or are just a scientific phenomenon. But after World War 2 it was the US Air Force that studied CO2 most carefully: it's heat-trapping properties could interfere with heat-seeking missiles. As the video says, "the atmosphere doesn't care whether you study it for warring, or warming. Adding CO2 turns up the planet's thermostat."
