Swedish newspaper Aftonbladet reports that parks in cities are up to 12 degrees centigrade cooler than commercial centers. A ten percent increase in green areas reduces the average city temperature by about 4 degrees; offsetting the UN climate committee’s extreme predictions of temperature increases over the next century.
Many scientists have criticized the UN predictions for lack of correspondence with real climate data. Al Gore and others have suggested an extreme political agenda in response to the predictions. The political agenda has been criticized for its projected devastating effect on western civilization without any corresponding benefit. Even assuming the UN predictions are correct, new thinking about the problem is demonstrating that there are effective ways to deal with city heat without such extreme political measures.
