Climate change challenge

Climate change: the problem
James Morrison, from Forest Research, talks about greenhouse gases including carbon dioxide, methane and ozone. He explains how we rely on these gases being in the atmosphere naturally, trapping the heat from the sun’s energy to prevent our planet from freezing. Since the industrial revolution the significant increase of these gases in the planet’s atmosphere, particularly of carbon dioxide (up by 36%), is speeding up climate change, with consequences for our forests as well as for people, both locally and globally.
