Let’s ask the question “Was the Brisbane flood caused by Climate Change?” The answer is… “caused?–no” but “worstened?–yes“.
Back in October we posted on this issue…
When asked about the Pakistan Flood, the Russian heat wave and other major extreme events of the last year, Dr James Hansen replied that it was the wrong question to ask. If the question was…
Would these events have occurred if atmospheric carbon dioxide had remained at its pre-industrial level of 280 ppm?”
then the answer would be… “Almost certainly not.”
This sort of answer would inevitably be read as a Yes by most of us.
There has been a lot of criticism of the Greens for daring to make this connection but the science does bear it out. Without a doubt we are seeing the impact of climate change in the increasing intensity of all the extreme weather events of today.
And this is only the start, it will get a lot worse as we go forward and warming continues to occur.
What can we expect to be the norm in 2020 and beyond? — Chaotic weather patterns where droughts willbe deeper and longer and floods will be more devestating.
We need to prepare for this by increasing controls on building in flood areas, designing for hotter conditions and anticipating shortages of water.
