Listening to a specialist global warming alarmist, you get the impression that warmer is always bad. It seems to be the cause of every possible means of our Armageddon. We’ll be pursued by the seas until every human being has drowned, cities destroyed by increasingly violent hurricanes, successive failed crops starving the world and a take over of the world by tropical diseases. It even causes earthquakes. Cooler is good, warmer is bad. They like to remind us that in a warmer world, more people will die in heat waves. They don’t like us to consider the greater number of lives that may be saved from fewer colder temperatures.
It’s not like the earth has an optimal temperature that we should strive to maintain. Sometimes it gets cooler, sometimes it get warmer. Sometimes it detrimental, sometimes its beneficial. So, for all the fears of higher temperatures, are we better off hotter or colder? In Geelong this week, we’ve had beautiful weather. A refreshing change from the wet and freezing days we’ve had of late. I’d forgotten what it was like to have a 21 degree day. So personally, I prefer summers over winters, and I’d rather it be 5 degrees over todays temperature that 5 degrees under. It’s good for cricket.
Yes, too much heat can kill you as good as too little, but human history has shown us that it’s better to be on the warm side. Just contrast the little ice age and the medieval warm period. Right now, we are at one of the cooler points in the current interglacial, the Holocene and we can’t be more than a couple of thousand years off the next ice age. Let’s not forget the dangers of a climate ten degrees cooler than today, and put things in perspective. Let’s drop this idea that warming can only be bad.
