Waiting, Waiting, Waiting….

 30 years is not very long in the Earth’s temperature record, BUT…

62 years is signifigant.

We were told – “Climate Change is here and now” and “we must act NOW before it is too late”.

Since WW2, around 1950, 62 years ago, we have seen an almost exponential rise in atmospheric carbon dioxide as per this CSIRO graph http://www.csiro.au/en/Outcomes/Climate/Understanding/State-of-the-Climate-2012/Greenhouse-Gases.aspx

http://www.csiro.au/~/media/CSIROau/Outcomes/Climate/Understanding/State%20of%20the%20climate%202012/P8-figure2-bottom_inline.ashx (you can ignore the green and the blue curves, the Earth’s GHG is water vapour, measured at around 0.4% of the Atmosphere, CO2 is a trivial 0.04%, methane is an insulting 0.000179% and nitrous oxide is a really, really insulting 0.00003% – here http://en.wikipedia.org/wiki/Atmosphere_of_Earth )

Now, while the level of the trivial GHG carbon dioxide took off almost exponentially in 1950, 62 years later “The Globe” has simply not warmed. The swings of a fraction of degree in this following graph are trivial. They are entirely in the range of normal, natural variation and show no human footprint on global temperature whatsoever.

Satellites have measured the whole globe, land and sea, since 1980, here is the data plotted as a temperature anomaly – that is, how the monthly global average temperature varies from the norm or average. http://www.drroyspencer.com/latest-global-temperatures/

“Latest Global Average Tropospheric Temperatures – Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The signals that these microwave radiometers measure at different microwave frequencies are directly proportional to the temperature of different, deep layers of the atmosphere. Every month, John Christy and I update global temperature datasets (see here and here)that represent the piecing together of the temperature data from a total of eleven instruments flying on eleven different satellites over the years. As of early 2011, our most stable instrument for this monitoring is the Advanced Microwave Sounding Unit (AMSU-A) flying on NASA’s Aqua satellite and providing data since late 2002. The graph above represents the latest update; updates are usually made within the first week of every month. Contrary to some reports, the satellite measurements are not calibrated in any way with the global surface-based thermometer records of temperature. They instead use their own on-board precision redundant platinum resistance thermometers calibrated to a laboratory reference standard before launch.” 

Do I see your eyes glazing over at the term “temperature anomalies”?!
Well, it’s because if you just plotted the global temperature by itself you would only get a straight line.
Here is the plot of the actual global temperature that I dug out – while it ends in 2007, trust me it is still a straight line in 2012!

 

Climate Change is NOT “here and now” and we obviously do NOT need to “act now before it is too late”. Climate Change is supposed to be caused by human carbon dioxide causing “the globe” to warm. It’s just not happening. We do not see it.

We can wait and see if the planet actually does need our help before we panic and try to “save” it for nothing!
