Here's another news.com story before I go home:
CLIMATE change is confusing. It's either the end of the world and we're all going to die. Or it's an overblown threat involving "warmists" and the "IPCC".
If you feel like you don't fully understand what's going on, you're not alone.
Plenty of people have an opinion on what is happening. But what are the facts and how does it affect you?
1. WHAT IS CLIMATE CHANGE?
Climate change is global warming. The two are the same thing. It is the world getting hotter.
No one doubts it is happening. The last decade, 2000 to 2010, was the hottest on record. The big controversy is about what is causing it.
2. RIGHT. BUT DID HUMANS CAUSE IT?
Yes. But it's understandable if you're not convinced. Plenty of people don't believe it. And sceptics have plenty of questions: What if the solar flares make the world hot? Doesn't the climate always change? Isn't it a good thing?
All of these have serious answers from very smart people. You can find these busted myths at the bottom of this piece.
But you do need to know one small statistic: 95 per cent.
That's how certain the United Nations climate science panel is that climate change is manmade.
3. REMIND ME HOW IT WORKS
Science boffins named John Tyndall and Svante Arrhenius figured out how it works in the late 19th century. It's simple. Basically:
Heat + Manmade gases that keep heat = Hot Earth
Global warming is caused by so-called "greenhouse gases". The gases, such as carbon dioxide, absorb heat and keep the planet warm enough for us to live on.
But humans - and yes, cows farting - have added so many tonnes of it into the atmosphere over the past hundred years that it has warmed up the planet.
4. SO IT WILL BE REALLY HOT?
Our summers are already getting longer by a day or two each decade, heatwave expert Sarah Perkins told news.com.au. Heatwaves are becoming increasingly common in the cooler months.
Then there's the kicker. By 2070, Australia is expected to warm between 1.0 to 5 degrees Celsius, according to the CSIRO.
It's the difference between a cool day and a scorcher where you melt into a little puddle.
5. SO HOT IT CAUSES BUSHFIRES?
It's difficult to say. Arsonists cause fires. So do lit cigarettes, dry conditions and the high fuel load of bushland.
But heatwaves and predicted drier conditions in southern Australia can help create the conditions where bushfires are more likely to happen, heatwave expert Sarah Perkins told news.com.au.
6. WHAT ABOUT SEA LEVELS?
On average the nation will experience a 300-fold increase in "flooding events" by the year 2100, according to a report released by Australia's Antarctic Climate and Ecosystems Cooperative Research Centre. That means one-in-a-hundred year floods will become considerably more common.
(not a real picture)
7. AT LEAST YOU DON'T LIVE HERE
We are actually lucky compared to the poor folk of the small nation of Tuvalu, found halfway between Australia and Hawaii.
It's easily one of the countries that will suffer the most. Much of the country could be flooded.
"This is a 'life or death' survival issue for Tuvalu," the country's now leader, Enele Sopoaga, pleaded with the world in 2010.
The entire population of the tiny chain of nine Pacific Islands lives under 2m above sea level. As you can see.
The global average sea level could rise by a metre by the end of the century if emissions remain high. If they are lower, levels could rise between 28cm and 60cm.
They have it tough enough already when a cyclone hits. "There are no mountains to climb, no inland to run to. Of course, there are coconut trees," Mr Sopoaga said.
Another low-lying nation, the Maldives, has reportedly weighed up moving its population to Australia.
8. THE GOOD NEWS ... AND THE ACID NEWS
Finally. Some good news from this global warming mess. More time at the beach for you!
You're in luck if you live on the east coast of Australia and find the ocean too cold most of the time. The water's getting warmer much quicker than the rest of the ocean.
Sucks if you live in the ocean though. The warmer currents will disrupt how tropical fish move around, oceanographer Erik Van Sebille from UNSW's Climate Systems Science Centre said.
Meanwhile, the oceans are becoming more acidic as well. The oceans absorb around 30 per cent of the carbon dioxide humans have emitted into the atmosphere.
9. WHERE DOES IT END?
A "tipping point" means we can't go back. The Earth's climate would have changed in a way that's irreversible. At least for thousands of years.
Scientists want to keep the temperature rise to 2 degrees Celsius or less, otherwise the IPCC warns we will see "catastrophic" damage.
To prevent that, the international community including the world's biggest polluters, the US and China, needs to sign a deal to slash emissions.
10. CAN I DO SOMETHING?
At the end of the day, you're just a small fish in a big blue pond hurtling through space.
There are little things you can do, especially recycling and switching off that power-guzzling air conditioner. Ultimately, the most powerful tool you have is your right to vote.

I've been following both topics for more than 30 years. before the terms were coined. these topics may have only recently become generally discussed, but they have been on the radar for decades.

If you want something to worry about, and this is something to be very worried about, worry about the
deteriorating conditions in Fukushima.
Fukushima will affect life on this earth, and is now, and will only get worse
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
After their last failure to control it now the core has melted through the containment wall into the
cooling area and they are worried it may start a chain reaction.
People think atomic power is "clean" because they can not see the contamination.
At least not untill it is dark.:-)

replying to no one in particular
Even if the climate change deniers are right and the planet is not heating up, it is no excuse to continue to spew pollutants into the atmosphere, is it?
We know that factories and industry does this. They generate pollutant particular matter and pollutant gases which can only have a deleterious effect on the landscape and on the animals living there, including us.
Even if there is no proven correlation between industrial pollutants and a warming world, we should still make every effort to clean up our act and not rubbish Australia or any other part of this world we live on.
Intelligent folks don't destroy their own backyard. You know it makes sense.

I agree with you there, acacia.
It doesnt take rocket science or graphs or statistics or pie charts to know that forests being levelled, resources being taken out the ground and oceans at an unprecedented level, to manufacture throwaway products and meangless gadgets, during which manufacture gases and chemicals are blown into the atmosphere and/or released into waterways, is going to upset the balance of nature humans animals and plants need live on!
Unless you've got your eyes wide shut, you can see it happening all around you!
Here we are plundering the earth to make throwaway furniture, toys, and meaningless gadgets, which in disposal cause further pollution and will do so for millennia!
What makes me laugh is that the blame is being put on the end-user, as in don't wast water, turn off your airconditioners and heaters, recycle your paper.
Got to be joking!
How much power is being used by manufacturers and food companies to make one-off or short term items, and unhealthy food, in disposable, unrecyclable packaging, which in bulk is often bigger than the actual item?
How much power and is being used and how much waste is created by hospitals to try and make us well again?
How much power is used in those sports stadiums and rock concerts staged to keep us amused while being herded into high consumer lifestyles which make lots of money for lots of corporations?
