Some of the natural causes may include volcanic activity and solar output. A great percentage of climate change has been attributed to human activities mainly, burning of fossil fuels and industrial waste gives rise to high carbon dioxide levels in the atmosphere. (CEICC & BLS & DE & LSNRC, 23). Water bodies around the world have also been affected by climate change. Many of these water bodies are a major source of water to be consumed by animals and humans and also to be used for agricultural purposes. Change in climate such as Global Warming and depletion of these water bodies is causing adverse affects to our environment and the ecosystem. Some of these effects include an increase in drought and floods causing people to be displaced. It also leads to less fresh water causing a reduction in the food produced and the revenue from agriculture (CEICC et al, 23).“Climate change is also driving changes in phenology”(pg 20). Polar bears are known to be completely dependent on ice to survive. Since 2008, polar bear has been among endangered species and many other creatures might soon follow suit if the climatic conditions continue with in the current trend. There are other creatures that are troubled by the changing climate and sea turtles are among them. They are affected by the rising temperature and sea levels at the sea (CEICC et al, 24).Currently there are six species of sea turtles that have been enlisted as endangered. They include loggerheads, green turtles, kemp’s ridleys, leatherbacks, hawksbills and olive ridleys. They are endangered due to the erosion of their nesting beaches and invasion by humans and animals that prey on their eggs. The reproduction of sea turtles is directly affected by climate change in three ways. Climate change causes sea levels to rise which washes away the sand on low level sand beaches. This reduces their nesting areas making it difficult for them to lay their eggs and reproduce. Secondly, climate change causes a rise in temperature. This affects the sand in that it becomes unfavorably hot for egg incubation. This in turn means that the eggs do not get to hatch. Thirdly, the high temperature affects the sex of the egg. The incubation temperature determines the egg’s sex and high temperature favors females. If this continues, at some point, no male sea turtles will be present and reproduction will stop (CEICC et al, 23).“If all the different species in an ecosystem
