500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.
The longer history of the proxy is then used to reconstruct temperature from earlier periods. Proxy records must be averaged in some fashion if a global or hemispheric record is desired. The "Composite Plus Scaling" (CPS) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures.
2006 – Weather radar improved by adding common precipitation to it such as freezing rain, rain and snow mixed, and snow for the first time. 2007 – The Fujita scale is replaced with the Enhanced Fujita scale for National Weather Service tornado assessments. [83] 2010s – Weather radar dramatically advances with more detailed options. [specify]
