Iconic Graphs of Climate Change

The bottom line, according to the IPCC (Intergovernmental Panel on Climate Change), which includes thousands of scientists worldwide who review and synthesize studies on basic science, observations, and models:

Our climate is changing (mostly warming, with more episodic rainfall)
Humans are responsible for most (but not all)

David Kennedy, editor in chief of Science Magazine:
“Consensus as strong as the one that has developed around this topic is rare in science.”

Keeling Curve CO₂ concentrations have been rising at a constant rate (and also fluctuating on a yearly basis)	CO₂ and Temperature Temperature and CO₂ fit together.
Mann Graph Late twentieth century warmth is unprecedented in the last millennium -- a result that has held up to a lot of scrutiny	Multiple Temperature Reconstructions Many different temperature reconstructions, using many different proxies, all agree: it's getting warmer.
Multiple GCMs There are many Global Circulation Models out there, but they all tell approximately the same story -- temperature is rising.	Temperature Scenarios We may be able to slow warming down with good development policy, but we won't be able to stop it.
Modeled vs. Observed Temperatures You need both anthropogenic and natural forcing to accurately model twentieth century temperature.	European Heat Waves What we think of as a heat wave now will be normal summer temperatures within <100 years.
Worldwide Climate Network Measuring temperature and weather around the world	A Warmer World Warming and precipitation will NOT be spread evenly around the world.
GHG Emissions Per Capita The average American causes twice as much CO₂ emission as a European, 4-5 times as much as a Chinese person, and 40-100 times as much as an African person	GHG Emissions Per Country Emissions from China have overtaken emissions from the US -- of course, they have 4 times as many people as we do...
