According to WWF Impacts vary in different kinds of forests. Sub-Arctic boreal forests are likely to be particularly badly affected, with tree lines gradually retreating north as temperatures rise. In tropical forests such as the Amazon, where there’s abundant biodiversity, even modest levels of climate change can cause high levels of extinction.
When large areas of forest are destroyed it’s disastrous for the local species and communities that rely on them. Dying trees emit their stores of carbon dioxide, adding to atmospheric greenhouse gases and setting us on a course for runaway global warming.
