Global efforts to tackle climate change are wildly off track, says the UN, as new data shows that warming gases are accumulating faster than at any time in human existence Researchers are also worried that forests are losing their ability to soak up carbon, which could be contributing to record levels of warming gas in the atmosphere, with more than a third of tree species facing extinction. Helen Briggs reports. Trees are vital to help clean the air we breathe, soak up carbon emissions and provide a home for thousands of different birds, mammals and insects. Yet it's been revealed that more than a third of trees around the world are in trouble. Experts here at Q worked on the latest Extinction Red List, which found deforestation is a major threat to life on Earth. 38% of the world's trees are threatened with extinction. More than all the threatened mammals, birds, amphibians and reptiles added together. So a huge number of species. And these are found all across the world. In 192 countries, there is a threatened tree species. So yeah, there's, there's work to do everywhere. Extinction list is an ever growing tally of living things facing extinction with more than 16,000 tree species at risk, like this Willamie pine. And if you take away the trees, you lose habitat for other living things from birds to mammals.
