Explanation:
UV (ultraviolet) levels are high in the areas of high altitudes. Tibetan plateau being the highest plateau of the world is more exposed to the UV radiations as the atmosphere gets thinner in the areas of higher altitude. So it can not filter the maximum of ultraviolet radiations. Tibetan plateau is on 4,500 meters height and the UV level increase by 10-12% upon every 1000 meter elevation.
However in those areas having the constant cloud cover like in Congo Basin the UV level is low as the clouds scatter the most of the UV radiations and they particularly stop the UV-B radiations. Thats why the cloudy areas have less UV level then the areas having a cloudless clear sky.
The two biggest aspects of the global climate change that impact the forests are the temperature and the precipitation. The temperature increases globally, this affects the forests because the trees are adapted on certain temperatures, but now are faced with rapid increase of the same, and the time for adaptation is much shortened, so lots of forests degrade or gradually die off. The precipitation is a crucial factor for all plants. The forests are on places where there's sufficient amount of precipitation, but now lots of regions in the world are suffering from reduced precipitation, this also causes the degrading and dying off of the forests.
