Climate Change
Climate change is a major problem that is affecting the world we live in today. It is causing animals to become extinct, glaciers to melt, abnormal seasonal changes, and more. One factor that plays into climate change is greenhouse gases. The main greenhouse gases are carbon dioxide, methane, and nitrous oxide. The role of greenhouse gasses is to keep the earth from becoming too cold for life. Greenhouse gases, which keep the earth from being inhabitable, have dangerously increased due to humans causing a global climate change.
First of all, for anyone that does not know what climate change is, it is a change in the world’s climate. A lot of people think weather and climate …show more content…
In 1999, the death of the last Golden Toad in Central America was marked to be the first documented species driven to extinction by climate change. Climate change and global warming has changed the animal’s distribution and behavior. What I mean be this is that there are birds that are migrating earlier, and in some countries they don’t even leave anymore because the climate is suitable all year around. The report, from the UN 's Intergovernmental Panel on Climate Change (IPCC), finds that many life-forms are moving north or into deeper waters to survive as their habitats shift. The melting of glaciers is causing the Adélie penguin, an artic bird, to go extinct because their home is on the undersides of ice sheets where they find refuge and algae as food. But as glaciers are melting away, their populations are falling—meaning that the penguins have to migrate farther to find food. Spending a lot more energy to find food makes penguins less successful at breeding and raising young, the scientists said. Spreading of diseases like malaria and dengue fever, which are mostly found in Africa and the Asia-Pacific, are expected to increase as disease transmitting mosquitoes are traveling across to colder regions. The IPCC, said in its 2013 report that “even modest warming may drive large increases in transmission of malaria, if conditions are otherwise suitable.” Sea level are also rising due to glaciers melting. The increasing CO2 emissions from fossil fuel combustion have led to an exponential increase in the net amount of CO2 being dissolved in the ocean. Dissolved CO2 creates carbonic acid, which reduces the ocean pH level, making it more acidic. This is bad as it would very likely have a major impact on the ocean life. If the CO2 concentration continues to rise and the pH level continues to fall at current rates, the ocean pH could drop by as much as 0.5 during the 22nd
