A few months ago, I was debating Canada’s sorry record on global warming on a CBC message board with dozens of people from across the country; order cialis online without prescription.As I wrote, a hurricane was bearing down on Nova Scotia; order cialis online without prescription.Several people raged at me, arguing that I was way off topic; I was told that this story was about good people getting battered about in a tragic display of nature’s power, and my attempts to link it to global warming were not only wrong, they were in incredibly poor taste.
Have a thought for the poor people in Nova Scotia, you moron, and stop trying to score political points! one Westerner suggested – order cialis online without prescription.Or words to that effect.
Moron indeed! Perhaps he didn’t realize that I lived in Nova Scotia, that Hurricane Kyle was going to pass right over my head.Perhaps he didn’t realize that the poor people in Nova Scotia have been hit by three hurricanes in 12 years that have caused hundreds of millions of dollars in damage order cialis online without prescription, and destroyed pristine wilderness areas.Perhaps he doesn’t realize that climate experts are expecting our hurricane seasons to grow longer, and more intense for a very simple reason: Global warming is increasing oceanic temperatures, and higher temperatures feed stronger hurricanes – order cialis online without prescription. Order cialis online without prescription: perhaps he didn’t realize that the special climate change advisor to the UK government recently described 4 Hurricane Katrinas hitting the US each year as a “credible threat.” *
And now we have Victoria.Like the high arctic, Australia is the proverbial Canary of the Coal Mine, the place where climate change would first hit — hard and unforgivingly; order cialis online without prescription.What’s happening in Victoria seems like something conjured by a Hollywood disaster movie, only it’s real, and terrible, and heartbreaking.
The media has, by and large, miffed the story – order cialis online without prescription. (Reuters gets it right order cialis online without prescription, the AP gets it wrong). Order cialis online without prescription: the fires were caused by arsonists, but they were no ordinary fires.Dr; order cialis online without prescription.Tim Flannery order cialis online without prescription, the biology professor at the University of Macquarie who wrote The Weather Makers, takes up the story in an editorial in The Guardian.
This February, at the zenith of a record-breaking heatwave with several days over 40C, Melbourne recorded its hottest day ever – a suffocating 46.1C, with even higher temperatures occurring in rural Victoria. Order cialis online without prescription: this extreme coincided with exceptionally strong northerly winds, which were followed by an abrupt southerly change.This brought a cooling, but it was the shift in wind direction that caught so many in a deadly trap; order cialis online without prescription.Such conditions have occurred before. Order cialis online without prescription: in 1939 and 1983 they led to dangerous fires.But this time the conditions were more extreme than ever before, and the 12-year “drought” meant that plant tissues were almost bone dry.
Despite narrowly missing the 1983 Victorian fires, and then losing a house to the 1994 Sydney bushfires, I had not previously appreciated the difference a degree or two of additional heat, and a dry soil, can make to the ferocity of a fire – order cialis online without prescription. Order cialis online without prescription: this fire was quantatively different from anything seen before.Strategies that are sensible in less extreme conditions, such as staying to defend your home or fleeing in a car when you see flames, become fatal options under such oven-like circumstances; order cialis online without prescription.Indeed, there are few safe options indeed in such conditions, except to flee at the first sign of smoke.
My country is still in shock at the loss of so many lives – order cialis online without prescription.But inevitably we will look for lessons from this natural tragedy; order cialis online without prescription.The first such lesson I fear is that we must anticipate more such terrible blazes in future, for the world’s addiction to burning fossil fuels goes on unabated, with 10 billion tonnes being released last year alone.And there is now no doubt that the pollution is laying the preconditions necessary for more such blazes…
We need to act now; order cialis online without prescription.Our planet has warmed by less than 1°C over the last 100 years; order cialis online without prescription.But if we continue business as usual, we could see warming of between 5°-7°C by 2100
In my part time, whenever I can grab a minute here and there, I work on a novel – order cialis online without prescription.So I have a vibrant imagination, but I can’t make my mind go there – order cialis online without prescription.

If you want to read more about global warming and how it’s affecting Australia, might I suggest Brave New Climate.
*OK, OK, so unless he had a time machine, that westerner in October couldn’t have known about comments that would be made in his future — and just a few days ago — by Jonathan Porritt; order cialis online without prescription.But I still don’t think he was very bright!
But I digress; I had another point to make about Hurricane Katrina – order cialis online without prescription.Anyone who says that a single devastating hurricane was caused by global warming doesn’t understand the science.So many variables went into creating this particular storm of the century that we can’t know exactly what role climate change played.
But we can say that climate change is creating conditions that make hurricanes like Katrina far more likely order cialis online without prescription, and we can say that its likely to get much worse.Climate stations in the US and the UK are predicting that — barring a volcanic eruption — one of the next two years will be the warmest years on record.
That means that we’ll see more catastrophes like the ones that devastated Victoria and New Orleans – order cialis online without prescription.
I too get very frustrated working with a bunch of people that refuse to believe all of the hurricanes we have been getting are due to global warming. We live near Tampa and the thought of a hurricane like Katrina terrifies me. The models of Pinellas County show that almost our entire county would be under water in a Cat 4 hurricane. My sister in law and her husband lived in New Orleans during Katrina, and had to move as a result, since the hospital they worked at closed. I get very frustrated that governments are not acting quickly enough. I know Obama is committed to helping, but I feel Congress is not cooperating. Everyone in Washington needs to stop bickering and get something done, now.
Hey Cheryl…
I’ve been wondering how you’re holding up!
I plan to write more about hurricanes soon. In a nutshell, the science is so strong that global warming will lead or more — and stronger — hurricanes that it’s a wonder that anyone would debate it.
The problem is that several studies have appeared in the literature that suggested that hurricanes have a cyclical nature, and seemed to wax and wane over a 70-year cycle (since we have records going back a few hundred years). It was a point of contention until other scientists discovered a false coincidence that gave this erroneous result… That the years with fewer hurricane also corresponded to years after major volcanic eruptions (and a few other events) that reduced temperatures around the world. So the research on hurricane cycles actually proves the theory that hotter weather makes for more hurricanes… But some deniers (and some scientists) still haven’t got the memo.
