Not even worth bothering providing a link to his tripe - apparently neither the drought nor the recent flooding rains are due to global warming. Ok I will here
As explained before - while a single event cannot be tied without question to global warming - the following remarks may be made.
1. There has beena decine in annual rainfall over eastern Australia.
2. Part of this is due to global warming. A study can be found here. Something else to review at some point.
3. The natural cycle of El Nino/La Nina will naturally lead to variability in rainfall.
4. Warmer temperatures means more evaporation and can increase atmospheric moisture, leading to heavy rainfall events.
Bolt is an ideologue, with little scientific sophistication and blogging a few quotes speaking about drought with an 'I told you so' tone proves little except to those whose politics and/or theology pre-disposes them to accept his ranting.
