The latest IPCC assessment report on global climate change has been released in Brussels on April 6. According to SPIEGEL INTERNATIONAL, the 27 member states of the European Union have already agreed to cut greenhouse gas emissions by 20 percent over the next 13 years, and to make sure that by 2020 at least one-fifth of all the energy used will be supplied from alternative sources. However, delegates from China and the United States — the two countries with the highest production of carbon dioxide, methane, and nitrous oxide gases — as well as from other countries like Russia and Saudi Arabia delayed the release of the report because they wanted parts of it changed. For example, they squabbled over the percentage of certainty that natural systems around the world are being affected by regional climate changes, particularly temperature increases — whether it’s 80 percent or 90 percent. Reminds me of the ostrich’s tactic — stick your head in the sand and pretend the danger isn’t there.
