Global warming is the increase in the temperature of Earth's atmosphere. The increases in the surface temperature and carbon dioxide have been faster in recent decades. In the 20th century, the earth's average temperature rose about 0.6° Celsius. (Timeforchange.org, 2015) The causes of this problem are many, the Intergovernmental Panel on Climate Change (IPCC) reported that most of global warming was being caused by greenhouse gases produced by human activities. Ice is melting worldwide, this includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.. Other examples of consequences are: Sea level rise became faster, butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas and precipitation has increased across the globe. (National Geographic, 2015) To understand better what global warming is, four branches of biology will be explained. (Biology-online.org, 2015) The first branch is biophysics which studies life, organisms, and environments. Biophysics includes solar activity, which is a big factor for global warming. According to Dr Raimund Muscheler solar activity in the modern day was causing about 0.1 degrees of warming in the 11-year solar cycle. (Mail Online, 2014) The second branch that will be explained is Conservation Biology which is developed from a strong evolutionary and ecological foundation. Conservation Biology includes species in extension, which is a consequence of global warming. Carbon dioxide levels and rising temperatures that could eliminate 56,000 plant and 3,700 animal species in the 25 hot spot regions. (Onlinelibrary.wiley.com, 2015) Other branch is biogeography, which studies the geographic distribution of organisms. This includes the habitat loss, which it is...
