For a great podcast mp3 on global warming from a scientific perspective (rather than an environmental scaremongers!), Australian author, Dr Barry Pittock of the CSIRO spoke on the ABC this morning. A transcript is available to read as well.
Seventy to eighty percent reductions of present greenhouse gas emissions are needed by 2100 to avoid potentially disastrous climate change. Moreover, if the poorer countries, which are not responsible for most emissions to date, are to be allowed to develop, the richer nations will need to shoulder more of the burden in the near future.
This requires a major technological revolution to move society from a carbon-intensive, fossil fuel based technology to a low carbon technology. This is a huge challenge, but one that can be met by setting suitable targets and incentives, combined with foresight, innovation and entrepreneurship. The cost of renewable energy has been falling fast over the last few decades and is increasingly competitive with fossil fuel energy, especially when the cost of pollution is taken into account.
This is the way of the future. Those individuals, companies and countries that seize the challenge and turn it into an opportunity will be in on the ground floor. Those who do not will lose out in the long run. The choice is ours.
A quick 14 minutes of information on global warming, climate change, environmental disasters, greenhouse gas emmisions, low-carbon energy sources, technological advancements, thoughts on coastal development and urban design, and free market vs government issues. You can find the transcript and audio here.
