10 charts on climate change that should have you very, very worried

Two major organizations released climate change reports this month warning of doom and gloom if we stick to our current course and fail to take more aggressive measures. A World Bank report imagines a world 4 degrees warmer, the temperature predicted

have you very, very worried Land ice The land ice sheets in both Antarctica and Greenland are losing mass. The continent of Antarctica (left chart) has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002. Artic Sea Ice September Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 . Arctic sea ice reaches its minimum each September. The graph above shows the average monthly Arctic sea ice extent in September from 1979 to 2010, derived from satellite observations. The September 2010 extent was the third lowest. Global surface temperature This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures. Global surface temperatures in 2010 tied 2005 as the warmest on record. Civil wars are on the rise In 2011, the world witnessed a spike in the number of active conflicts, rising to 37 from 31 in 2010. It was the largest increase between any two years since 1990 Wildfires are multiplying This map published in the National Research Council report shows how rising temperatures and increased evaporation will cause widespread fires in the western US Coral reefs are doomed Coral reefs, which protect against coastal flooding, storm surges, wave damage, and also provide homes for lots of fish, are doomed on our current course (And so is the study of them) There’s been a huge surge in the amount of empirical research linking climate change to an increase in violent conflicts within states. The idea is that shortages of food, water, and energy lead to health problems, unrest, instability, and armed conflict in affected areas Sea level Most of Greenland’s top ice layer
melted in four days During a week in the summer of 2012, Greenland’s ice cap went from melting on its periphery to melting over its entire surface America just had its worst
drought in over 50 years This past summer, the US experienced its worst drought in more than a half a century, severely reducing farm yields, livestock production, and raising food prices globally Sea level rise is caused by the expansion of sea water as it warms up in response to climate change and the widespread melting of land ice. The chart on the left shows historical sea level data derived from coastal tide gauge records. The chart on the right shows the average sea level since 1993 derived from global satellite measurements. Sources:
