Global warming exists in natural systems. Regional climate changes are expected with increasing global warming. Climate change affects particular ecosystems including coral reefs, mangroves, and tundra. Government policies must factor in the effect of high atmospheric carbon dioxide levels to increase global temperatures. There are adverse effects related to global warming. Climate change results to extinction of innumerable species as well as decreased ecosystems diversity. Atmospheric carbon dioxide concentrations increases culminate to ocean acidity increases. Dissolved carbon dioxide increases the level of ocean acidity. Such ocean acidification threatens fisheries, coral reefs, natural resources for society value, and protected species. Global warming magnitude is determined by anthropogenic carbon dioxide emissions. This is because of carbon dioxide long lifetime within the atmosphere.
Within lower troposphere, temperatures have been on the rise. Moreover, 2010 and 2005 were the Earth’s warmest years in the 21st century. These climatic changes are of major interest to the government. In 1998, El Nino culminated to huge surface temperatures increases. Today, global temperatures are subject to short-term fluctuations. A global warming interval happened between 2002 and 2009 with the earth experiencing some relative stability. Temperature changes do vary across the globe. These temperature variations are due to the consequences of global warming that are caused by increases in carbon emissions in planet Earth.
