【Watch Dark Desire Season 1 Online】

We may think we're clever with our internet-connected fridges and Watch Dark Desire Season 1 Onlinesuch, but the reality is much of what sustains us depends on simple things.

Having enough rain and not too much. For the sun to warm us, but not too much. Climate change is set to change all that.

Human history is marked by our sensitivity to natural changes in the climate, but this narrow band of comfort -- where conditions are best for supporting our food, our water and our health -- is fast being upended by man-caused global warming. What can we learn from the past?

This question was explored by epidemiologist Tony McMichael at the Australian National University, who died in 2014, leaving his work Climate Change and the Health of Nationsunfinished. The book has since been completed by environmental historian Cameron Muir and epidemiologist Alistair Woodward, and published in February.

Woodward, head of epidemiology at the University of Auckland, spoke with Mashableabout what the past, seen through the lens of climate change, can tell us about the future.

What is the "Goldilocks zone" referred to in the book? What does it mean for our health?

Everyone knows who Goldilocks was and the porridge that wasn't too hot, wasn't too cold. It was just right. Human life generally operates on the same principle. When it comes to our health and wellbeing, we really are dependent on our environment being in the "just right" zone.

We're physiologically evolved to manage within a particular climatic zone, and on top of that, we have social and cultural adaptions to climate that mean our houses are built in a particular style, we wear a particular type of clothes, we spend more or less time out of doors.

But if climate changes quickly, whether temperature goes up or down, we're stressed. And one of the expressions of that stress is a greater vulnerability to disease, injury and ill-health.

How could climate change contribute to and amplify ill health, as you write in the book?

From the health point of view, climate change is not going to lead to a whole host of problems we've never heard of before. There may be some, but they'll be in the minority. On the whole, we expect climate change will worsen problems we're alreadywrestling with.

Mosquito-born infections are one example of that. Water born infections -- infections getting into the water supply -- are a problem around the world.

"If the power supply goes down, then we are worse off than we would have been if we had never lived with air-conditioning."

In New Zealand, the threat we face is the effect of industrial-scale farming, particularly dairy farming, on the quality of fresh water and the risk of pathogens getting into our drinking water. That's a risk that is multiplied when you have a climate characterised by extremely heavy rainfall and long periods of drought.

What will make our current period different from past experiences of climatic change?

Are we as vulnerable as people were in the past? Obviously, we've got many potential defences we can call on, but remember it's only a third of the world that has air conditioning. Two thirds are as exposed to climatic hardship as people were in the time of the Roman Empire.

There are aspects of our modern world that actually put us at greater risk, and that's become apparent with things like Hurricane Katrina and major European heatwaves.

The fact that a third of the world's population has become accustomed to living in air conditioning means we've become very dependent on 24/7 power supply. If the power supply goes down, then we are worse off than we would have been if we had never lived with air-conditioning, because we live and work in a tower of glass and steel.

What humans are producing in the world's climate system is orders of magnitude greater than what people experienced in the past. The possibility that the world will warm another three or four or five degrees in the next 100 years -- that's never been experienced before.

What we're contemplating here is climate change of a different scale, and that's significant because adaptation is rate dependent. Our success in managing environmental change depends critically on how fast it occurs.

One thing that's pointed out in the book is that global warming is no respecter of wealth.

It's certainly true that many people feel cleverness and technology and wealth will enable us to adapt when we really have to, rather than facing the challenge of making changes in advance.

Well, it won't will it? You just need to think about the Victorian bushfires in Australia in 2009. One of the wealthiest countries in the world and how many people died? Hundreds in extraordinary devastation. That was because of the severity of the challenge -- the fires moved faster than ever before, they burned hotter than ever before.

Do you think our failure to understand human history and climate as closely related has been one reason why we haven't faced this challenge head on?

There was a period when historians wrote freely about climate and human events, and it was accepted that climate was an important influence on health, productivity and civil order. And then roughly in the middle of the 19th century onwards, that point of view was not so popular.

I think it was the industrial revolution. This awareness that humans were able to achieve remarkable things, to transform the landscape, to prevent disease -- to produce enormous suffering as the result of industrial-scale warfare.

My hunch is all those things soaked into the historical thinking and led to a shift from the natural environment to thinking about the actions of humans.

So we got infatuated with our ability to change human history? We forgot about outside forces?

Yes, that's right. Tony believed in the power of reason and debate and argument. We can fix this problem, he believed. I believe. It's more a matter of will and awareness.

I hope the book will provide knowledge and that it will ultimately stir greater willingness to act.
