Climate related trends

NASA has several interesting trend animations in their Climate Time Machine.

Carbon Dioxide

September 2002:

Time Series: 2002-2016, image #0

This time series shows global changes in the concentration and distribution of carbon dioxide since 2002 at an altitude range of 1.9 to 8 miles. The yellow-to-red regions indicate higher concentrations of CO2, while blue-to-green areas indicate lower concentrations, measured in parts per million.

Global Temperature


Time Series: 1884 to 2016, image #0

This color-coded map shows a progression of changing global surface temperatures since 1884. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.

Arctic Sea Ice


Time Series: 1979-2017, image #0

This visualization shows the annual Arctic sea ice minimum since 1979. At the end of each summer, the sea ice cover reaches its minimum extent, leaving what is called the perennial ice cover. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979

Obviously climate and it’s affects will fluctuate, and the climate is affected by more than man-made effects, but the trends and the human influence on them are a concern for the planet that needs ongoing monitoring and also mitigating efforts. The risk is too great to do nothing.
