I was playing a podcast of an ABC interview with Martin Frick. He illustrated that each degree of global warming translates into human suffering - referring to research by his organisation, showing that already 300,000 people are dying each year as a direct result of climate change.
This is the equivalent of the 2004 Indian Ocean tsunami every year. In all the conversation about future impacts of climate change, we can sometimes forget that it is already affect great numbers of people right now.
On a sidenote, he was in Australia for the Parliament of World Religions, and mentioned that "all the religious traditions have as a core piece of their beliefs a respect for this planet and a responsibility for this planet."
