There is widespread agreement among scientists that climate change is causing the planet to warm, but not necessarily causing the worst effects on the planet.
It is a contentious topic, with many different types of scientists, and a number of competing opinions.
But there is little disagreement about the fundamental facts of climate change: the increase in global temperatures over the last few decades has caused some of the worst weather events and droughts on record, the oceans are warming faster than ever, and it is happening at an unprecedented rate.
This has led to the greatest risk to life on Earth, the environment and ecosystems.
The debate is being driven by two different types: the first is a belief in the possibility of a rapid increase in the frequency and severity of extreme weather events, and the second is a scientific belief that climate changes are causing the greatest threat to life.
But what exactly are they?
The first is what’s called “the ‘uncertainty’ argument”.
It is based on the idea that if we are unable to predict when the future will be like it is now, then we cannot be confident that we can adapt to a changing world.
In other words, we cannot make a prediction about what the future might be like, so we should not act to prepare for it.
This is a controversial approach, but the consensus among climate scientists is that it is not a valid scientific argument.
The second type of argument is based around the concept of “social cost”.
This is the idea, based on a range of research, that if people are poor, or have low levels of income, or are already disadvantaged, then their behaviour, their choices, and their decisions are going to have a major impact on the future.
These are known as “negative externalities” in economic theory.
They are the costs associated with the actions of the individuals or organisations which may affect them.
In recent years, the economics of climate have become much more complex, as the evidence has been accumulating that human activities are contributing to the rise in global temperature.
The climate debate in Australia is being played out in a way that is more complicated than it has ever been before.
