Not really tech-related I know, but I was appalled over the weekend when I read the Intergovernmental Panel on Climate Change‘s (IPCC) summary report (pdf) on climate change.
The summary report is a 21 page document summarising a four volume report yet to be released. It is the work of over 1200 scientific authors and over 2500 scientific reviewers from over 130 countries.
The Intergovernmental Panel on Climate Change (IPCC) was established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) in 1988 to
assess on a comprehensive, objective, open and transparent basis the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation. The IPCC does not carry out research nor does it monitor climate related data or other relevant parameters. It bases its assessment mainly on peer reviewed and published scientific/technical literature.
The numbers and data in the report are horrifying.
Eleven of the last twelve years (1995 -2006) rank among the 12 warmest years in the instrumental record of global surface temperature
Observations since 1961 show that the average temperature of the global ocean has increased to depths of at least 3000 m and that the ocean has been absorbing more than 80% of the heat added to the climate system. Such warming causes seawater to expand, contributing to sea level rise
Global average sea level rose at an average rate of 1.8 [1.3 to 2.3] mm per year over 1961 to 2003. The rate was faster over 1993 to 2003, about 3.1 [2.4 to 3.8] mm per year.
For the next two decades a warming of about 0.2Â°C per decade is projected for a range of SRES emission scenarios. Even if the concentrations of all greenhouse gases and aerosols had been kept constant at year 2000 levels, a further warming of about 0.1Â°C per decade would be expected.
Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21st century that would very likely be larger than those observed during the 20th century.
Some of the graphs say it all:
What scared me even more was hearing one of the report’s lead authors, Dr Andrew Weaver on NewsTalk 106 on Friday afternoon and he said that the report was conservative in many of its estimates and findings. Not good.
UPDATE: – Expect to see more stories like the floodings in Jakarta as the effects of climate change become more and more pronounced.
One thought on “Climate change”
Climate change is a tech topic. Dan King connects the ideas with some very interesting data that documents the size of a carbon burden that comes with blade servers.
If you serve tech electronically, you are warming the globe.
If a brave journo equates the impending 2007 Tolka floods to global warming, I’ll bet Bertie Ahern starts to seriously consider doing something other than buying Ireland out of its Kyoto debt.
