Future impacts of Global Warming
The temperature of the air can increase by up to 5'c during this century if we do not reduce the emission of co2.This would change the climate of the Earth drastically.Severe weather like rainstorms may occur much more often than now.The rainfall in the winter will increase and the risk of flooding will be higher.In general,The rainfall will significantly reduce and long drought periods may happen more often.This would have serious effects to the agriculture,food production and the water resources.
coral reef bleaching:When the temperature of the sea water increases the symbiotic algae of corals which the corals need for their nutrition and give them their typical color can die.When the algae die,the color of the coral changes to white and we say the corals have bleached.
