Is Global Warming becoming unstoppable?


You are so keen to take the xxx(?) out of people that you resort to stupid assumptions. Grow up!


Rubbish.



From your link:

 
Calliope you really are bizzare.

Can we get it clear. When anyone wants to requote them-self or some else else we also expect to see "the same words used" . That is what quoting means. And there is quite a difference between your two statements.

With regard to global warming and polar bears. It is possible that some polar bears will survive a complete meltdown of the Arctic sea ice. How many ? In what form ? Where ? Who knows. But it won't be pretty.

The main point of the research is that there is extremely rapid warming in the Arctic which is seriously affecting polar bears as well as everything else that lives there. That of course was completely ignored by The Australian and it seems many other forum members.

And relatively soon of course all this melting ice is going to start impacting on the rest of the globe. The fact that the melting to date is also starting to release billions of tons of ice bound methane (as was reported earlier) just makes the situation even more precarious.
 

I am not much interested in what you expect. You have resorted to nit picking.



It's happened before. Species adapt.

But never at the current pace, have you read the "Sixth Extinction" specifically goes into the last five.

When you have been informed by such scientific analyses you can then speak with authority.
 
Interesting Calliope. In just a few words you appear to be accepting that there is rapid warming happening in the Arctic and that it will cause some big changes.

But you seem to think species will adapt as they always have.

As Explod suggests you might like to expand your understanding of the effects of the temperature increases that will happen if we continue on our current course. (Mind you we are already committed to at least 1.5 degrees of warming with the current levels of Greenhouse gases)

Elizabeth Colbert wrote an excellent book on this topic in 2006. An overview and the first chapter are featured in the New York Times.

There is an interview with Elizabeth which explores how she felt as she researched and wrote the book.

There you go again. You have a bad habit of trying to put words in peoples' mouths.

So now you are accepting Mr Plod as a disciple.. I think you should get over it and accept the fact that there is nothing we can do do to alter climate change. Chill out . Take up knitting. It soothes the nerves I'm told.
 
This year has been the worst year ever in the USA - by far- for natural weather disasters. They have got worse because there is more heat in the atmosphere. From PBS Newshour.

JEFF MASTERS: I mean, we talk about the Dust Bowl summer of 1936. Well, this summer pretty much matched that for temperature, almost the hottest summer in U.S. history. We also talk about the great 1974 tornado outbreak. Well, we had an outbreak that more than doubled the total of tornadoes we had during that iconic outbreak. And, also, we talk about the great 1927 flood on the Mississippi River. Well, the flood heights were even higher than that flood this year.

So, it just boggles my mind that we had three extreme weather events that matched those events in U.S. history.

HARI SREENIVASAN: So, Jeff, how do we tie this in with any particular cause? We can't say that a temperature warming or a global temperature increase causes a tornado or this hurricane. But what can we say? What does the data show us?

JEFF MASTERS: That weather has natural extremes.

We all know that you can have extreme years and not very extreme years. Certainly, this year was a very naturally extreme year. But I argue that when you have a naturally extreme year occurring within the context of global warming, okay, now you've put more heat in the atmosphere. That means you have more energy to power stronger storms and more energy also to give you more intense heat waves and droughts.

So, in particular, we look at heat waves, droughts, and flooding events. They all tend to get increased when you have this extra energy in the atmosphere. I call it being on steroids kind of for the atmosphere.

Australia gets a mention too as well as many other extreme weather events around the world.

Gosh, I didn't realize that Global Warming has taken the back seat of the bus to make way for weather.

Next up: The Barrier Reef (again) right? Then more pictures of scary steam from exhaust vents and grey skies from carbon pollution?

The Tax will save us all - I feel better already!
 
All good here in WA just weather.....


2011 to be Perth's hottest year ever on record

METEOROLOGISTS say 2011 will be Perth's hottest year in history - our third consecutive hottest year since records began.

2011 to be Perth's hottest year ever on record

A few questions:

1/ That appears to reflect daily maximums rather than daily means. On the face of it that is data mining, what is the average mean and how does that sit with the last 114 years of records (A very short period of time BTW)?

2/ Is it just Perth with this record, or other areas of WA as well?

3/ Perth is a rapidly growing metropolis with much new development and very little established tree coverage. How much of the record can be attributed to urban heat island effect?

IF, these and other questions must be answered and analyzed before any importance is assigned to that statistic.
 
Re recent methane alarmism, it seems the alarmist press and their acolytes have lept to delusions once again before properly analyzing.

Anthony Watts has the scoop http://wattsupwiththat.com/2011/12/27/quote-of-the-week-the-climbdown-on-methane-and-climate-change/

This quote from Semiletov and Shakhova themselves:

 
Ag people talk about heat units, which uses max and min temps. Anyone got any data on this for global warming? It may be better than maximum. May try to calculate it myself if I get time...
 
Heat - note that it was "almost" the hottest summer since records began. But then consider the huge amount of heat added by non-greenhouse gas sources. Fuel combustion, nuclear energy, land use change, hydro-electricity and wind energy are all adding plenty of heat directly to the atmosphere regardless of any CO2 they may emit. This alone would cause some warming, with or without the CO2 issue. Heat emission from these sources in the US are very much higher now than they were in 1936 when the use of coal, oil and hydro plus heat effects of land use change was very much lower whilst nuclear energy and electricity from wind power didn't exist at all (old style wind mills pumping water aren't really adding heat so far as I can work out).

Tornados - I'm no expert on them but there was a weather expert on Financial Sense Newshour a few years ago who predicted this based on some natural cycle that is already well understood.

Floods - Land use change since 1927 in the US has been on a massive scale and I don't think anyone would dispute that. Such changes have major impacts on runoff and that is something you can witness even outside your own home (assuming you have asphalt roads or concrete etc). No doubt there have been other changes too - dams, diversions, works along the river banks, water extraction etc which also impact flows. As such, measuring the flow is essentially meaningless unless your purpose relates directly to the flow in the river, water supply, navigation etc. It tells you nothing about the climate or rainfall due to the sheer number of changes upstream in the catchment.

I would certainly agree that from a scientific perspective (as distinct from climate change which is essentially a non-scientific political issue in practice) there is something which needs proper investigation regarding Perth's weather / climate.

There's clear evidence of things like a reduction in run-off and, I'm assured by those who live there, humidity is increasing also. Also notable is that essentially the same effects (though less severe), at the same time, have been observed in Tasmania which is only a bit further south.

The gas and electricity utilities use a similar measure known as "degree days".

Essentially, it's a measure used to translate weather forecasts into likely usage of heating and cooling systems which in many areas are a key driver of gas and electricity use (most extreme is South Australia where on a hot afternoon literally 60% of all electricity in SA is used for air-conditioning - hence the obvious benefit in being able to forecast usage with reasonable accuracy).
