Rain Forest Plants Race to Outrun Global Warming

Climate change is occurring so fast that it will cause the extinction of many different species.  Many different plant species in the rain forests are trying to reach higher altitudes to reach air cool enough that the plant can survive.  Due to climate change temperature is rising greatly which, if left alone, will cause many extinctions around the globe and this effect will most likely be seen first in the rain forests.  In order to try and counter climate change trees are going into a "dash" and are migrating vertically at a rate of 9-12 feet per year to try and reach air cool enough for their survival, but it is estimated that they would need to migrate at 20 feet per year to remain able to survive.  By 2100 half of the plant species seen could go extinct as a result of the increasing temperature and if the climate change increases at a rate faster than it is presently, this could raise to an extinction of 90% of species.  Many scientists are trying to investigate these tropical areas so that we can try to get a better understanding of how the areas will be affected because much of the tropics are unknown to us.  Some studies have proven that in varying elevations in the tropics there is little to no similarity in species as a result of differing habitats, so if all the plants and animals migrate, what will be the effect? It is not completely clear.  The effects of climate change on the tropics will impact the world and if it is left untreated, the world as we know it will cease to exist.  The only way we can change this is to reduce emissions of greenhouse gases and end the clear-cutting of forests to try and preserve the atmosphere before the world gets turned upside down.
