And given that there's been probably a ten-fold amount of information about terrorism through the media than there has about climate change; I think that's quite an interesting statistic.

Climate change is so big that people who study it.. and many do.. need to speak to it. They must present scientific papers, they must appear in public, they must speak to the media and we must hear their voices. In order to get policy right, policymakers.. governments.. need to make decisions based on sound science.

Once you start to look into the guts of climate change you find that just about every scientific institution in the world is conducting research on the issue.

There are a range of associated impacts related to increasing temperatures which affect both evaporation rates and river systems, which are already over stressed, and these will hit farming communities and the health of crop lands.

It is now well understood that humans ultimately depend on the health of the planet for their wellbeing.

I don't blame my own parents for the way I grew up, as quite often there is little choice in these issues.

The forces that are in play on climate change essentially revolve around the generation of power, the transportation of goods and services and people, and the sorts of materials that we use to fuel the whole of our civilisation.
