I blog about environmental and social justice issues because I am very concerned about the health of the interdependent web of life of which we are a part.

Many Lines of Evidence

Based on comprehensive data from multiple sources, the report defines 10 measurable planet-wide features used to gauge global temperature changes. The relative movement of each of these indicators proves consistent with a warming world. Seven indicators are rising: air temperature over land, sea-surface temperature, air temperature over oceans, sea level, ocean heat, humidity and tropospheric temperature in the “active-weather” layer of the atmosphere closest to the Earth’s surface. Three indicators are declining: Arctic sea ice, glaciers and spring snow cover in the Northern hemisphere.

(Graphic from the NOAA site.) Climate change is happening: many lines of evidence point in one direction -  up.  As in temperature rising.   And snow cover  and glaciers shrinking.   

I have seen climate change deniers skip directly from denial to  apathy between news articles. Yes - climate change is happening.    No, it isn't too late to change teh way we live.  As I've posted before, solutions exist.
