Global warming threatens tropics

The tropical areas in Costa Rica have been unusually hotter then usual. You're probably thinking, "the tropics are suppose to be hot so why does it matter?" Well it is a very big deal because most of the animals can only stand tempreture up to a certain level, but now its higher then usual which is effecting many of the animals that live in the tropical areas. Species already living on the mountiantops won't have anywhere to climb. This study the scientists are doing shows that most of the species won't survive or they could decline. A sheet of paper in the science report shows that the warming has scrambled the range of mammals in Yosemite National Park. For the very first time research proves the climate changes the plants and a few ecosystems.
I believe we should try and stop global warming because it is affecting many animals in the tropical region. Without most of the species living in the tropical areas we might be affected greatly because of the food chain. The food chain might be eliminated because the species in the tropical region will be eliminated with the global warming effect. In this article, it states that "moving uphill, the researchers said, temperature declines between 9.4 degrees Fahrenheit (5.2 C) and 11.7 degrees (6.5 C) for every 3,280 feet (1,000 meters). To get a similar reduction moving north or south, species would have to travel more than 620 miles (1,000 kilometers)." Because of this the animals will not be able to survive in this condition without food or water, which they might not be able to get because of the tempreture changes.
