Climate Change in Australia


#2763

Irma had twice the equivalent power of every bomb dropped in WW2


#2764

Are you generally interested in the science of hurricanes, how and why they form Albo?

We can talk hurricanes, it’s fascinating stuff.


#2765
  1. Yes
  2. Not really.

Currently more interested in discussing how many angels can fit on the head of a pin.


#2766

Heres some info from people who supposedly know about the weather climate change.

The Australian,

Funny.

Ben, one question , if chaos theory says “the butterfly effect” has relevance , what does a battery of 600 x 200 ft wind turbines in the North Sea have on Atlantic Ocean weather patterns. What do you think ?


#2771

Of course. That’s the part everyone talks about.


#2772

CSIRO did a study on the effect of 300 wind turbines in Central Highlands in Victoria.

Think the conclusion was that it the transfer of energy from wind to electricity, is so small compared to the total available windy energy that there is no measurable effect.


#2773

Weather is more effected by current than anything thay occurs above the water.

Temperate and Current

Chaos theory actually says (much abbreviated, but bear me out…) that some systems over the long term are very sensitive to initial conditions, so can’t be accurately simulated to a fine level of detail. So a the existence or otherwise of a windfarm may have an effect on this year’s atlantic weather patterns, but so might the logging or otherwise of a forest, or your decision whether or not to turn your heater on tomorrow.

It is for this reason that climate scientists talk about, well, climate rather than weather, cos climate is an average over time of the weather, and so smooths over the short-term perturbations caused by this sort of thing. They talk about ‘increased RISK of storms’ or ‘decreased average rainfall’ rather than ‘oh noes we must cut co2 emissions or it’ll rain on grand final day in 2079’.

But if you actually want a simple answer - all other things being equal, wind farms are more likely to reduce the severity of storms than otherwise. Why/ Because wind farms sap the energy of weather patterrns. That’s the whole point of wind farms after all - they take energy out of bodies of moving air and turn it into electrical power. And a weather pattern with less energy is one where the winds are not as strong and destructive. Of course, the amount of energy captured by a windfarm is minute on the scale of a weather pattern, so the impact will be infinitesimally small, but what impact there is will more likely result in calmer weather rather than stormier weather, chaos theory notwithstanding.

Two in 23 hours is even morre alarming.


#2776

Usually, but Irma formed in waters 2 degrees cooler than usual.


#2777

So like virtually everything in life, politics , religion, sex , science very few people know anything , some know something , but 97% know absolutely nothing . The one with the loudest voice often wins , That is unless someone punches them on the nose.


#2778

97% seems high.
I’ve always put that figure around 8% and up to 16% in times of stress.


#2779

Maybe this should be in POlitics thread, but here is OK too.

Tanya Plibersek pointed out Turnbull was now criticising the exact policy he had claimed to support and personally voted for back in 2010:

“My question is to the Prime Minister. The Prime Minister
used to say, ‘I will not lead a party that is not as committed to
effective action on climate change as I am.’ Has the Prime Minister
forgotten that when Labor was in Government, not only did he support the
policies he just ridiculed, he crossed the floor to vote for them?”


#2780

Ha. Yep. 7 years ago Malc was launching a plan to have 100% renewables by 2020. Interesting it doesn’t get mentioned much. Now it’s "let’s keep this ■■■■ box open till at least 2027.


#2781

Which is odd enough. It picked up its energy from there with warmer water in the gulf of course. There’s no known link with warmer conditions forming tropical cyclones.


#2782

Hurricane Maria expected to hit all the same spots Irma did
