You are the one doing this.

I thought you were going to stay out of the Politics forum.

Oh so you mean  Natural (Real) Climate Change....which we cannot aaffect one way or the other????

Ok thanks for clarifying....

So in reference to the thread title........exactly what action should the Liberal Party take on Natural Climate Change????

I guess if push came to shove, natural and human climate change can not be differentiated since humans are a natural part of the system.

Yet that would take a certain amount of ignorance.


Easter Island is a perfect microcosm : it was able to support a human population

Humans took it for granted, and started to deforest the Island.

When all the trees were chopped down, the human population crashed due to starvation.


Now the macrocosm : Deforestation is changing weather patterns and climate across the planet.

Deforestation is only one part of the human effect on climate, yet the easiest to prove.

Time to shift on this debate Neo Con Liberals. Time to formulate policies of human caused climate change adaptation. Ask your small l Liberals for advice, they are awake to the threat of human caused climate change.

Or learn from the political party who have been correct on environment all along ~ The Greens.

Then it could be possible for Liberals and Greens to work together ... even in some sort of alliance in government if the opportunity presented itself in NSW after March.

Or what are the Greens policies on natural climate change LOL

Outstanding, so we have survived through 4.6 million years of climate change.

Yep - did you know Mars' temperature has continued to climb over the last 40 years by the same relative temperature as Earth?

Now could it be the sun that both planets orbit?

Or has human factory emissions on Earth changed Mars' temperature too.

If so, we've managed some feat.

A. Have humans been around for 4.6 Billion Years?

B. Got any data about Mar's temps Andrei. I reckon you are pulling everyone's leg with that comment.

C. And if Mar's temp has climbed like earths ... this disproves all the bull the denialists have said about the planet cooling in the last few years.

CLIMATE change sceptics have seized on news that Mars is heating up to back their claim that humans are not causing Earthly global warming.

The research comes from US planetary scientists, who suggest the Red Planet warmed by about 0.65C from the 1970s to the 1990s, similar to Earth's 0.6C average temperature rise during the 20th Century.

"It could be coincidental or it might be the needle in the haystack," said climatologist William Kininmonth, former head of the National Climate Centre in Melbourne.

"It's an interesting observation, as it's the same time period as Earth's temperature has been warming."

Mr Kininmonth said the research, published in the journal Nature, showed there was enough natural climate variability to account for global warming on Earth.

Not so, claimed Neville Nicholls, a climate scientist at Monash University in Melbourne.

"The paper is interesting but it hasn't got anything to do with the question of human impact on global warming on Earth," Dr Nicholls said.

"It's not an excuse to argue that humans are not causing global warming on Earth."

The research was done by a team led by Lori Fenton of the NASA Ames Research Centre at Moffett Field, California.

They used a computer model based on those devised to study global warming on Earth, adding Martian features such as a cold, airless surface and a shifting south polar ice cap while subtracting Earth's oceans and atmosphere.

Dr Fenton's group found that annual variation in the solar radiation reflected from the surface of Mars - its "albedo" - contributed to the warming by causing more blowing dust.

Over the past 30 years the dust swept clean large swaths of the planet's surface, reducing reflected radiation.

The result was a "positive feedback loop" between dust, wind, albedo and temperature.

"It's a nice piece of work," said UNSW climate scientist Andy Pitman.

"But there are no implications for Earth."

Professor Pitman was lead author of the climate modelling section of the Intergovernmental Panel on Climate Change report released in February.

Professor Pitman disputed Associate Professor Franks' claim that changes in Earth's albedo had a bigger influence on climate than greenhouse gases such as carbon dioxide.

"Albedo is included in climate models," Professor Pitman said.

"It can have a local effect but cannot explain the observed warming record."
