Australian warmist scaremongering: "Alice Springs would resemble the Sudan, Darwin will resemble like no place on earth"

"The world added roughly 100 billion tons of carbon to the atmosphere between 2000 and 2010. That is about a quarter of all the CO2 put there by humanity since 1750."
"Over the past 15 years air temperatures at the Earth's surface have been flat while greenhouse-gas emissions have continued to soar" 
The Economist

No matter what happens in the real world, global warming alarmists are desperately trying to sell their scare stories. Here is an Associate Professor of Environmental Policy at Melbourne University peddling his message of doom and gloom:

" a book published today paints a terrifying picture of a world that's four degrees warmer and recommends a dramatic increase in Australia's carbon reduction target.*

The book's editor is Associate Professor of Environmental Policy at Melbourne University, Dr Peter Christoff.*

ELEANOR HALL: What is the most frightening aspect for you of a four degree warmer world?

PETER CHRISTOFF: Oh look, that's a terrible question to which one only has to give a terrible answer. There are a set of compounding problems that emerge when you start moving towards four degrees. You start to see a world in which there are substantial extinctions.

The oceans have become warmer, are becoming more acidic. So there's a very significant chance of the collapse of significant marine ecosystems like coral reefs, the Great Barrier Reef, for example, is probably doomed when you get to four degrees. There are very substantial problems with food availability planet-wide and in a country like Australia which used to be capable of producing a surplus of food, by four degrees, would probably be facing food security problems with a larger population, but also a hungrier population.

And then you have the issues of extreme weather events, floods, more intense storms, bushfires, all these things particularly in the Australian context, I think leave us with a shatteringly different sense of what Australian can and would be like.

ELEANOR HALL: The physical effects are one part of this. What could the changes in the resource availability then mean for security? Will it inevitably mean more wars?

PETER CHRISTOFF: The projections are at four degrees that you would have significant displacement of population. If you have mass hunger occurring, populations will move to try and find food. Most of those movements, and the projections go from 65 to 250 million people by the end of this century. Most of those movements are likely to occur with countries, but there would be also the prospect of people moving over their borders and looking for resources elsewhere.

And how the world begins to handle a problem of that magnitude I think is something that we can only begin to contemplate. One doesn't know whether it would lead to more conflict. It certainly would lead to problems. I don't think we can understand what a world that looks like the one that's being projected looks like or how we're going to react to it. It's beyond human experience.

ELEANOR HALL: This sounds like a doomsday scenario. Could humans adapt to a four degree warming of the planet?

PETER CHRISTOFF: Well, humans are an extraordinarily adaptable species but if you're looking at a population of seven billion people trying to adapt to a world in which there's less water and less food, one would have to say that the prospects for an adaptation that would leave life looking roughly like it does for many people at this point in time is virtually impossible.

So there are already billions of people living in poverty or in water-stressed and food-stressed circumstances. In a four degree world, their situation would only get extremely worse. And even in extremely wealthy countries like Australia, adaptation I think would be very, very difficult to countenance.

There would clearly be some form of adaptation, but it wouldn't be life as we understand it at this point in time.

ELEANOR HALL: You say that Australia could be one of the most vulnerable continents. Where do you expect to see the worst effects in Australia of a four degree warmer world?

PETER CHRISTOFF: There will be the extinctions of species. There'll be a very substantial impact on agricultural productivity. So the issues of food availability will change. We probably have the wealth and the resources to begin to deal with some of the issues of water availability and desalinisation plants and so on. Everyday life will be very substantially different. There are projections for example of what would happen to just average temperatures over time. So in Melbourne for example, we have something like nine or ten days over 35 degrees at the moment. By the time you get to 2070, that's about 26 days.

When you're looking at Alice Springs, the temperatures are 90 days over 35 degrees now, 180 by 2070. And then you get to places like Darwin, which would move from 11 days to 308. You end up with parts of Australia which are virtually unliveable. And the projections are for example, that while Alice Springs would resemble the Sudan, Darwin will resemble like no place on earth."
