Congratulations on the climate change blog-a-thon!

Here's a quick contruibution sent from a speeding train heading back to Edinburgh:

Climate change has been described as the biggest threat humankind fces in the 21'st century. Tackling it is a massive challenge , and all too often it can feel just too big for any of us as inividuals to do anything about it. The truth though, is that we can each make a big difference. Every time we leave the TV on standby or forget to turn the lights off we add yet more greenhouse gas to the atmosphere and so turn the global thermostat up another tiny notch. By saving energy at home and at school or work, avoiding travelling by car an plane wherever possible, and following the "Reduce, Reuse, Recycle" rule we can keep huge amounts of greenhouse gases from being released - as much as 1000 tonnes in a single lifetime. Today's young people face a possible future of dangerous climate changes because of the fossil fuels burnt by their parents and grandparents. They can deservedly be angry with us, but they can also help decide just how bad things get.

Best wishes,
