Global Warming skeptics - how do you explain these data?

I doubt that you are looking for the facts. You are probably looking to support your conclusion that we are all going to die and its the fault of mankind. In fact, the climate has generally warmed for the last few thousand years with some important ups and downs. One of the last downs was from 1940s to 70s and so, anectdotally, it may seem to you that we are warming alarmingly. In fact we are just continuing the trend of slow warming. The temperature warmed about a degree last century and will be similar for this century. People that push a global warming agenda never discuss the benefits. They focus on possible consequences, always exaggerating them. Far more people die of cold related deaths. As a geologists, I understand that sea levels and particular habitats are seldom stable (if ever). To imply that any change is bad is irresponsible and just plain ignorant. To imply that warming is bad is ridiculous. There will be good and bad. There is some warming going on but the real question is how much humans have impacted it and if we have what could we do to slow it down or stop it. There is very little indication that humans have had much of an effect. If we did, then why was there cooling in the 1940s to 70s. If we have little effect, then your worries will accomplish nothing except possible adverse effects on our way of life and economy and possible early death from stress by the worriers.
