Climate science more complex than thought

Comments on Mike Steketee “Global weather disasters a sign the heat is on”, 8/01/2011, http://www.theaustralian.com.au/news/opinion/global-weather-disasters-a-sign-the-heat-is-on/story-e6frg6zo-1225983256858

To Mike Steketee, is this statement correct?

"So far the increase since the mid-18th century of all greenhouse gases has been 38 per cent, including a 27.5 per cent rise from 1990 to 2009."

It does not seem right, given the the longer history of industrialisation.

Secondly, you say that "The temperature of 46.4C in Melbourne on Black Saturday was more than 3C above the previous highest for February." Are you sure the causation, that is which caused which or which proceeded which?

You cited a number of individual example, such as Moscow. Are you sure there were no worse conditions before in the long history?

Your approach does not appear to be scientific, I am afraid to say.

From these few points, it does not suggest that your argument is convincing. It may actually do disservice to the cause and undermine the global efforts on climate change.
 
In the long history of the earth, there have been more extreme weathers and a few individual locations or years can be drown out easily.
