    Energy is defined as the ability to do work, such as propel the body forward by taking a step (motion). Energy and its ability to do work are measured in joules: power (watts) x time (seconds) and work joules = force (newtons) x distance (Trefil et al, 2010). Energy exists in many forms; kinetic (motion or movement), potential (stored), thermal/heat (atoms and molecules), wave and mass (Trefil et al, 2010) to name a few. Energy is interchangeable, thus it can be changed from one form to another. Where might all of this energy come from? All living systems and/or organisms are sustained through a process call photosynthesis which harnesses energy from the Sun for the purpose of providing dietary sustenance to the inhabitants of the Earth. Conversely, the Sun supplies the radiation necessary to heat and light the Earth, which is beneficial to all living systems and/or organisms. Hence, the Sun is the origin of energy. The focus of my essay will be to explore the current ways in which we use the Sun’s energy to supply heat and light on Earth, the advantages and disadvantages of our current energy methods and/or sources, and ways in which we can utilize renewable energy sources and reduce and conserve our current energy consumption.…

    Sunspots have usually a diameter of about 37,00km and appear as dark spots within the photosphere. There is a strong radial magnetic field within a sunspot. There is an even better correlation with the length of the solar cycle, between years of the highest numbers of sunspots. Recent research shows that the combined effects of sunspot-induced changes in solar irradiance and increases in atmospheric greenhouse gases offer the best explanation for the observed rise in average global temperature over the last century. The Earth’s climate is always changing. The Sun is the source of the energy that causes the motion of the atmosphere and thereby controls weather and climate. “During stable conditions there has to be a balance between the energy received from the sun and the energy that the earth radiates back into space.” The climate changes prior to the industrial era may be strongly influenced by variations in solar activity.…

    The atmosphere retains some of the heat and energy via atmospheric windows and clouds. These clouds and atmospheric windows all emit their own energy. As well as clouds, greenhouse gases, the leading cause of global warming, maintain and refrain heat from leaving the oxygen hence why the globe is heating up. Greenhouse gases include carbon dioxide, which is why the greenhouse gas levels are rising at an alarming…

    2. Solar radiation gets absorbed by the Earth's surface when it reaches Earth. This emits infrared radiation into the land, ice and water. Greenhouse gases warm the lower atmosphere because they re-emit infrared radiation in all directions that travels back downward warming the lower atmosphere. This has led to the phenomenon as the Greenhouse Effect.…

    There is a scientific consensus that the recent rise in global temperature (global warming) is caused by human enhancement of the greenhouse effect, where greenhouse gases absorb outgoing long-wave radiation, so less is reflected back to space and is essential for keeping the planet warm. However, too much greenhouse gas in the atmosphere means too much energy is trapped and the planet warms up. One of the key findings in the IPCC report is the attribution of more than half the increase in global surface temperatures from 1951-2010 to human activities, underlining the dominant role of fossil fuel burning as a…

    Satellites orbiting the earth and other advanced technologies have enabled scientists to collect many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in…
