First topic message reminder :

Australian researchers say a global tracker monitoring energy use per person points to 2C warming by 2030

The world is on track to reach dangerous levels of global warming much sooner than expected, according to new Australian research that highlights the alarming implications of rising energy demand.

University of Queensland and Griffith University researchers have developed a “global energy tracker” which predicts average world temperatures could climb 1.5C above pre-industrial levels by 2020.

That forecast, based on new modelling using long-term average projections on economic growth, population growth and energy use per person, points to a 2C rise by 2030.

The UN conference on climate change in Paris last year agreed to a 1.5C rise as the preferred limit to protect vulnerable island states, and a 2C rise as the absolute limit.

The new modelling is the brainchild of Ben Hankamer from UQ’s institute for molecular bioscience and Liam Wagner from Griffith University’s department of accounting, finance and economics, whose work was published in the journal Plos One on Thursday.

It is the first model to include energy use per person – which has more than doubled since 1950 – alongside economic and population growth as a way of predicting carbon emissions and corresponding temperature increases.

The researchers said the earlier than expected advance of global warming revealed by their modelling added a newfound urgency to the switch from fossil fuels to renewables.

Hankamer said: “The more the economy grows, the more energy you use ... the conclusion really is that economists and environmentalists are on the same side and have both come to the same conclusion: we’ve got to act now and we don’t have much time.”

Wagner said the model suggested the surge in energy consumption was not offset by improvements in energy efficiency.

He said energy use per person was on track to rise sixfold by 2050, which had dire implications for temperatures when combined with economic growth of 3.9% a year (the six-decade average) and a world population of 9 billion.
“Massive increases in energy consumption would be necessary to alleviate poverty for the nearly 50% of the world’s population who live on less than $2.50 a day,” Wagner said.

“We have a choice: leave people in poverty and speed towards dangerous global warming through the increased use of fossil fuels, or transition rapidly to renewables.”

Hankamer said: “When you think about statements like ‘coal is good for humanity’ because we’re pulling people out of poverty, it’s just not true”.

“You would have to burn so much coal in order to get the energy to provide people with a living to get them off $2.50 a day that [temperature rises] would just go through the roof very quickly.”

The researchers suggested switching $500bn in subsidies for fossil fuels worldwide to renewables as a “cost neutral” way to fast-track the energy transition.

Wagner said pulling the rug from out under the fossil fuels industry was a move of “creative destruction” and “more a political issue rather than an economic issue”.

“If we swapped those subsidies globally, of course we could have rapid improvement and deployment of renewables to cover our shift from fossil fuels,” he said.

“You’re pushing a huge amount of capital into a different sector that requires an enormous amount of growth, so you would actually see a great deal more growth from putting it into renewables than providing it for fossil fuels.”

Hankamer said the fact that about 80% of the world’s energy was for fuel, and only 20% for electricity, meant “we don’t have any easy solutions”.

“If we want to do this, we need to do things like solar fuels, or think about how we do battery technologies and fully transition to electric,” he said.

“The things that are going to be hard to replace are aviation fuels and things for heavy machinery and probably shipping.

“We can do electric cars for short runs but those things are going to be really hard to switch.”

2 degrees doesn't seem like much does it?   But it will make a huge difference to the world, destroy plant and animal habitat, reduce crop yields, more flooding and drought.  We have already seen how much it is changing with the floods this year, FGS when are governments going to wake up and take action!   I want a world for my grandchildren and their children to grow up in.

So 'YOU' feel justified with looking at what we know 'NOW' vs what they knew WAAAAAYYYYY back then Dangerous global warming will happen sooner than thought – study  - Page 3 2787774761 And then you are using what limited information you have at your disposal to compare/exam/relate data taken and provided from a plethora of non-scientific documents --- as GOD WRITTEN FACTS & RELIABLE DATA vs what we have proven and linked to drilled ice core samples and rock formations as well as 3,500 year old hieroglyphics carvings!!! 

Yipper...you just keep pushing that load of 'MANURE' up hill and see how much doesn't fall out on you! Dangerous global warming will happen sooner than thought – study  - Page 3 Crap-hitting-the-fan


No... not at all... I never said any such thing...!

OK... so how far back would THESE PARTICULAR 'weather stations' have records from...!?


Dangerous global warming will happen sooner than thought – study  - Page 3 Lol
For some unknown reason... you seem to be trying to claim that the "weather stations" in your examples above, are also now somehow able to monitor weather data from Egypt 3500 years ago and even further back...!?

It is you lot who are flip flopping around and moving the goalposts!!!


I have remained consistent throughout!!!


Maybe you should read back through my posts from the start of the thread, and then explain exactly what it was I said that you disagree with...!?

So after all your puff and bluster... you still can't show anything I've said here to be wrong...!?
