From advances in renewable power to the clear impacts of climate change, to denying the lot of it, climate and energy issues in 2013 are sometimes best expressed through graphs. Here are eight of the best from throughout the year: Global Temperatures Keep Going Up Carbon Final The chart above shows how dramatically temperatures have spiked in recent years, largely due to greenhouse gas pollution. The blue line shows global temperature levels over the last 11,300 years, and that spike right at the end shows what “temperature is changing 50 times faster than it did during the time modern civilization and agriculture developed” actually looks like. The red line is the best estimate scientists have for what the temperature is likely to be in the near future if we continue on our current trend. The more greenhouse gases are emitted, the more they trap heat within the atmosphere before […]
