Our survival depends on fighting climate change

 They’re a threat to our children’s future.”President Obama said recently, “More droughts and floods and wildfires are not a joke. They’re a threat to our children’s future.” now, while I still have a voice to speak, I want to communicate a warning: I believe we are at a crossroads that puts our civilization at risk.  If we do nothing to stop carbon dioxide from going into the atmosphere, the Earth will face a future similar to that of Mars, becoming barren and lifeless.

When World War II was thrust on us, we turned our economic system into a war machine as every American agreed to sacrifice in order to defeat Nazi Germany and its allies. That is the model for what it will take to overcome what now threatens our planet.

• Planning for a shortage and excess of water.
  Cities and towns need to take a strategic view of water supply and storm water. The East London Green Grid aims to create a network of open spaces with the potential for managing surface water and flood risks and generating energy.
• Moderating the urban heat island.
  Cities and towns are warmer than surrounding areas because heat is stored in concrete and tarmac and traffic and poor air circulation compound the problem. Green spaces are protected across Stuttgart explicitly to promote cool airflows, improve air quality and reduce the heat island effect.
• Making green spaces work for people and wildlife.
  Urban green areas can be a significant source of sustainable food, help community cohesion and protect biodiversity. Benwell Nature Park in Newcastle is now a focal point for community that helped create it and Warrington has pioneered the establishment of urban forestry.
