Melting Arctic Sea ice should be the warning we need about expanding coal exports. Michael Sonnabend
Despite peak global temperatures in 2005 and 2010 (unprecedented in the instrumental record), a recent sharp plunge in volume of the Arctic Sea ice and a spate of extreme weather events, coal mining, coal exports and carbon emissions continue to grow, overwhelming any mitigation attempted by schemes such as the Australian carbon price.
And although both – local emissions and emissions from exported Australian coal – are vented into the same atmosphere, in political terms it appears as if they occur on different planets.
Following the peak El-Niño event of 1998, when mean global temperatures reached +0.45 degrees Celsius above pre-1975 levels, a decline of temperatures during 1999-2000 was heralded as “global cooling” ..
Unfortunately from 2001 temperatures continued to rise. There were peak temperatures of +0.46C (2005) and +0.47C (2010) in the instrumental record (see figure 1). The 2011 La-Niña year saw the peak temperature of 0.4C higher than all previously recorded La-Niña years.
The rise in mean global temperature would be about double the above figures, had it not been for the transient masking effects of short-lived sulphur aerosols .. https://theconversation.edu.au/beyond-two-degrees-celsius-sulphur-wont-save-us-for-long-1885 .. emitted from fossil fuel combustion .. http://pubs.giss.nasa.gov/abs/ha06510a.html . However, with the onset of clean air policies in the 1980s, SO2 emissions began to decline (see figure 2), which in part explains the sharp rise in temperatures from about 1975-1976 (see figure 1).
STUFF IT! .. try as i may none of the images will copy for me so temperature has
risen exponentially while posting .. SHOULD have checked the first one .. MORE ..
