Climate change...

[CENTURION]

Put ice in a cup of water. let it melt see if the levels rise? no it wont as water expands when it melts.

yes it will, there is the amount of ice that is sticking above the water's level that will make the level rise, once all of the ice has melted.

[CENTURION]

I can't wait for levels to rise, fishing off my front porch sounds kinda relaxing!

Get two bottles of water filled to the top and screw the lid on tight.

Put one in the fridge and the other out in the sun on hot day.

What happens to them?

[CENTURION]

one gets cold and one gets hot, derr.....

What happens to them?

Both would get drunk if its a hot day

[dedja]

Correct ...

[CENTURION]

you get nematodes?

[Q.]

you get nematodes?

They both give you cancer from the dioxins in reused water bottles.

...how much of the change is in excess of what could be expected from the normal cycles, and whether human impact is a major or minor factor in the current climate change.

The CSIRO and the Bureau of Meteorology have stated that: Rising CO2 emissions from the burning of fossil fuels has affected global temperature much more than natural climate variability during the past century.

if water expands when it melts wouldn't that make the level rise? I'm not sure, I'm not particularly good at physics.

As I understand it the ice that is floating will not directly contribute to sea level rise when it melts, but the land based ice and glaciers will. Also, thermal expansion of sea water as the temperature rises will also cause the sea level to rise. This Wikipedia page has more info.

doesn't mean its related to climate change ...

The scientists say that it is:

The United Nations's (UN) chief climate science body says there is no doubt last week's extreme heat in Australia is part of a global warming trend.

I didn't think it broke any temperature records.

Australia swelters through hottest ever day

The hot weather that has fuelled fires in southern Australia has also delivered the nation its hottest day since records began a century ago.

The national temperature is the average of hundreds of daily readings across the country and it hit 40.3 degrees on Monday. (January 7th)

I'd want to find time to read their raw data and their analysis of it, and their explanation of how the believe they can distinguish between warming from the natural cycles and that we generate. Then I'd like to do my own analysis of their method, and scientific rigor.

I'd also like to check whether they have taken steps to eliminate any bias generated by using only results recorded since the recent end of the Little Ice Age in the late 19th century when most meteorological record keeping began.

Some encouraging news from the US:

Barack Obama promises US action on climate

President Barack Obama yesterday vowed to put the fight against global warming at the heart of his next four-year term in office.

Sweeping aside years of American prevarication on whether to act on emissions, Obama promised the US would lead the world in its efforts to curb global warming, and in the development of the technologies to achieve this goal.

"We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," he said on Monday in his inaugural address to the nation.

With the horrors of superstorm Sandy and the recent US droughts fresh reminders that extreme weather events are becoming more severe and frequent – a trend predicted by climate models – Obama sniped at Americans who still deny that human activity is to blame.

"Some may still deny the overwhelming judgement of science, but none can avoid the devastating impact of raging fires and crippling drought, and more powerful storms," he said.

simple solution, chemtrail the crap out of the earth & reduce its population to a more manageable 100,000,000.

Guess he will be rushing right out immediantly to give endorsement to the Kyoto Protocol and to introduce a Carbon Tax on the population as Julia Gillard has done? The evidence is all there, and they have had many years to look at it, no need to wait any longer....

I read a week or 2 ago, that the usa is carbon neutral anyway, because of the extensive forested area in the west and northwest. Probably not true, but I wonder how much more forest they would need to be carbon neutral.

How Obama will deliver his climate promise

BARACK OBAMA is certainly talking the talk on climate change - promising to put the fight against global warming at the heart of his second term. What's more surprising is that the US - historically, the world's biggest emitter - actually seems to be walking the walk. It is on track to meet Obama's 2009 pledge to cut US emissions by 17 per cent, from 2005 levels, by 2020. The target could even be exceeded, which may give a boost to the long-stalled international climate talks.

There's no realistic possibility of passing new laws to curb US greenhouse gas emissions - Republican control of the House of Representatives will see to that. So some pundits were scratching their heads at Obama's climate pledge in last week's inaugural address. But independent analyses paint an upbeat picture of the progress he can make simply by using existing laws.

Study finds more frequent heatwaves 'will kill hundreds' in Adelaide

AN extra 1900 Adelaide people will die as a result of heatwaves linked to global warming by 2050, experts say.

The estimate, done by the Centre for Risk and Community Safety at RMIT University, is based on modelling it presented to a Senate inquiry into preparations for more frequent and devastating natural disasters linked to climate change.

The Victorian university submitted a figure of more than 6200 extra heatwave deaths for Melbourne and said an additional 1926 deaths would occur in Adelaide, over and above the predicted number of deaths if no climate change took place.

This Adelaide estimate is conservative because the city "is predicted to face more severe extreme heat increases than Melbourne," RMIT said.

Not only will more lives will be lost and flora, fauna and agriculture destroyed, emergency services resources will also be strained, the submission said.

Increased bushfire damage to south-eastern Australian ecosystems is estimated to cost an extra $1.5 billion over the next 37 years.

RMIT recommended the committee "consider that even very conservative estimates of disaster costs under climate change are significant and likely warrant investment in disaster risk reduction and climate change adaptation".

The Australasian Fire and Emergency Service Authorities Council told the committee it predicted in 2009 that climate change would result in a greater frequency and higher intensity of bushfires, more storms, higher winds and increased flooding.

It said "emergency services have been involved in responding to the realisation of that prediction" ever since.

This included the Queensland floods in 2010/11, the Victorian floods of 2011, and bushfires in Tasmania and NSW this month, which "were associated with record high average maximum temperatures in Australia".
