The battle over Brexit may be over, but it is not over to the extent that many people think.
Climate change is far more than the “Brexit” issue that some politicians are trying to push, said James Delingpole, a professor of environmental engineering at the University of Sydney.
It is a battle of “two very different issues”, he told the ABC’s Insiders program on Sunday.
For one thing, climate change is a global phenomenon and we can’t predict what will happen.
The consequences are potentially catastrophic.
For another, there are already severe problems that climate change will create, he said.
“Climate change may be the tipping point that finally brings us to a tipping point of climate instability,” he said, adding that the issue is a topic of intense debate in the scientific community.
“What you see now is that there is a consensus that we have reached a tipping points.”
That’s what makes this so interesting.
“What is the problem?
There are two main types of climate change: extreme heatwaves and extreme rainfall.
The former is the most significant because it can lead to floods and drought, and can cause crop failure.
But there is also extreme drought, which can lead both to increased food insecurity and climate-change-related extreme weather.
Scientists have long warned that the effects of climate-related extremes are already being felt in Australia.
The average global temperature has risen by 0.9 degrees Celsius in the past century.
But recent research has shown that more than half of the global warming in recent decades is happening in Australia and its southern neighbour, the United States.
Climate scientist and former National Research Council chairman James Delespole says it is a case of two very different problems.
