Warming The rate at which oceans are warming may not sound dramatic - the temperature rise over the past century is estimated at about 0.1 degree Celsius - but that is enough to kill the algae that keep corals alive, move species into new areas, and cause sea levels to rise. Water cycles throughout the system continuously as the sun’s radiation causes it to evaporate, rise into the atmosphere, condense, then fall as precipitation to be used or recycled. It causes the reduction of oxygen level in the water which hampers the life of animals and plants of oceans. please give what you can to help animals thrive.
