One important issue of the G-8 summit (June 6-8 in Heiligendamm, Germany) is the question of how to tackle global warming. Research conducted for example by NASA and Columbia University Earth Institute finds that human-made greenhouse gases have brought the climate close to critical tipping points – with potentially hazardous consequences. Although doubted by many, the summit may deliver prospects for a meaningful deal to combat global warming. German chancellor Merkel asks for a commitment from the participating nations to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit) this century and further to reduce global greenhouse gas emissions by 50 percent below 1990 levels by 2050.

But what’s that got to do with the future of our cities? A lot!
In broader terms, these serious environmental questions may also have effect on life in our cities and thus affect the future of our cities. In terms of preventing critical consequences, the development of our growing cities and urban agglomerations worldwide play a decisive role – in the report “Bericht zur Lage der Welt 2007” these even are seen as the key to tackling global warming. According to the report, climate change will especially have impact on fast-growing Megacities in the southern hemisphere – but these cities also hold great potential for facing the problems and challenges, and taking action for facing global warming.

At this point, I would like to introduce the project architecture2030, which recognizes the responsibility and the role of architecture in the current situation and delivers fruitful insights into key methods of resolution. The site is absolutely worth a visit!

What is your opinion about the climate change and the role of our cities? With this background, where do you see the future of our cities?
