Global warming is defined as the increase in temperature of the Earth's atmosphere, and it causes everlasting changes in the climate of the Earth. Many people think that global warming doesn't exist and consider it to be a hoax, or at least an issue blown out of proportion for political reasons. With that said, however, scientists worldwide have agreed with the fact the fact that there is a gradual increase in the temperature of the Earth.
Looking at the scientific community's analysis of climate change, Earth's temperature has risen more than 0.4 °C in the course of recent years. Carbon dioxide and greenhouse gases released in an amplified amount in recent decades have been the main cause of increase in Earths temperature.
Scientists and researchers state that by 2100 the normal worldwide temperatures increase will be somewhere around 1.4 and 5.8 °C. The effects of global warming are the melting of ice in the polar region, increase in sea level, and drastic climate change i.e. very cold winters, and very hot summers.
Depletion of Caribbean corals:
Elkhorn and Staghorn corals are some of the oldest corals at about 3.5 million years old. They have been the highlight of the Caribbean reef for quite some time, but during the last 40 years there has been a gradual decrease in them with more than 90% of them killed.
The main cause of this is a disease called "White band," which creates a dead white zone across the corals.
You must be wondering what Global warming has to do with the degradation of these corals. Well, the increase in the temperature of the ocean is the main cause of this so called "white band" disease. This disease is said to worsen if the corals do not get cooling periods after summers. So indirectly, global warming is the cause of the depletion in Caribbean corals.
