The milankovitch theory implies that over time three cyclic events vary the amount of solar radiation that reaches the earth and eventually it causes climate change. According to Burroughs (2007) eccentricity is a cyclical variation that determines the shape of the earth’s orbit around the sun. The more elliptical the earth’s orbit is, the greater the the greater the variation in solar energy that is received at the top of the atmosphere between the earth’s perihelion and aphelion. As the earth rotates on its axis, it wobbles hence changing the timing of the solstices, and equinoxes a process known as the procession of the equinox. Volcanic eruptions eject large amounts of sulphur dioxide gas which reacts water vapor found in the stratosphere to form a dense layer that reduces atmospheric transmission of sun’s incoming radiation. Sun spots, which are caused by the sun’s magnetic field are dark, planet sized regions that appear on the sun’s surface. These regions are colder than with an average temperature of 4,000K. Climate change can be explained by these factors although they are only some of those which cause climate change.
Since 1979, the summer polar ice cap’s size has shrunk more than 20% and this has not only affected the natives but the globe as a whole. The contraction of the arctic ice cap accelerates global warming since the protective, cooling layer over the arctic is melting and hence the earth absorbs more sunlight (Kininmonth 2004). If the arctic is warmer, this will affect weather patterns since the rest of the world will also warm up and eventually food production will decrease. In contrast, most of the world depends on melted glaciers for fresh water supply through lakes and rivers hence their melting will cause short supply of the same. It will also cause shortage of electricity since a great percentage of the world’s population depends on melting glaciers for hydro electric power. Animals, birds and fish will lose their ...

The climate change is the term that is used to refer the Global warming due to the emission of the green house gases. The major reason of the climate change is the emissions of green house gases. The issue is now realized and many governments and industries try to opt more sustainable ways instead of utilizing the conventional methods to generate energy.
Although it is a devastating dilemma, we are not left hopeless. Climate change urges rapid modifications on how we run our systems by altering our individual lifestyles, establishing legislation as the nation’s aid, and participation of other countries in this endeavor.
Climate change can be due to: Natural variability – warming or cooling due to sun spot activity, solar radiation Human activity – burning of fossil gases into the atmosphere, causing enhanced greenhouse effect However, there is much debate about what causes climate change, and the UN Framework Convention on Climate Change refers to a change of climate that is attributed directly or indirectly to human activity that alters the global atmosphere.
Changing temperatures and unpredictable swings in the jet stream continue to alter the distribution and predictability of precipitation throughout the country, all caused by climate changes. Though the root cause of climate change is not fully understood, the long-term impact on ecosystems throughout the United States is an altered environment in which humans, animals and infrastructures have grown dependent upon.
Significantly, climate change predictions give man knowledge of the future; and these predictions cannot compared to magic, neither are they opinions or speculations.(Ricky, 2008, 1) Climate predictions are based on investigation in the field of science i.e.
Solutions have to be in place before the overall temperature of the Earth rises beyond two degrees Celsius: a tipping point when impacts are deemed irreversible by the European Union. This change in climate is primarily caused by carbon dioxide emissions from anthropogenic activities such as burning fossil fuels for energy consumption.
ions that have contributed to climate change and as such have committed to address the issue and assist developing countries in reducing their admissions. There are many negative consequences as a result of climate change and here rising sea levels will be discussed.
This is a problem. It shows that scientists do not always think about international problems in general. Instead, they try to prove that their field of study is the most essential. Both, the U.S. space program and oceanic exploration, are important for the
