As with Earth, if Earth takes in more heat than it can let out, or vice versa, there will be global climate changes. This begs the question, what could cause these imbalances to happen on Earth? Earth’s carbon levels have followed a natural cycle throughout the past 800,000 years where the carbon dioxide concentration varied from 180 ppm (parts per million) and 280 ppm which resulted in several changes in the environment.. In the grand scheme of Earth, these changes are miniscule and have stayed within the natural cycle. But when looking through the eyes of humans, these changes are drastic causing ice ages, draughts, and rain for years (Goldstein 6).
For instance, the global temperatures increased by an average 1 degree Celsius in the past century. Furthermore, the methane reserves that exist in frozen forms are now being released into the atmosphere due to the increasing global temperatures. Methane has a higher destructive potential than carbon dioxide due to its contribution to the greenhouse gases bank. The weather patterns are now no longer predictable with erratic rains being experienced even in formerly stable ecosystems resulting to regular floods. Addressing the danger to carbon dioxide sinks is part of the solution to this somewhat global disaster, and the methods to do so differ.
Climate Change can result from both natural events and human activities. Some examples of natural causes of climate change are volcanic eruptions, ocean currents, solar variations, and earth’s orbital changes. Some examples of human activities are fossil fuels, warming of temperature due to industrialization, and deforestation of tropical rainforests. Factors of climate change can change and vary naturally over time. The issue of the fast increase in earth’s temperature over the past years is one of global importance and disputed origin.
The earth is warming rapidly and there are changes affecting everyone. The scientists have a large amount of data proving that global warming is very prevalent, and is creating many problems. Many tests have been done to calculate the levels of carbon dioxide and the temperature of the earth from the past years. Global warming is causing many things to rise. The temperature is rising due to the greenhouse gases trapping the light and keeping it in the atmosphere.
Arguably one of the most oft debated topics in recent years, the effects of global warming pose a threat to the world economy. Growth in the economy can spur changes in climate that have the ability to prove both beneficial and impeding to economic prosperity. An understanding of economic principals can provide insight onto the costs that are incurred with growth of industry and the methods that can be implemented to cede further negative effects. Global warming, by definition, is an increase in the temperature of the Earth’s atmosphere and oceans. With the rise in modern technology, the average temperature of the Earth’s surface has increased about 1.4 °F; two-thirds of which has arisen since the early 1980’s.
There is a quote “Don’t blow it- good planets are hard to find”, which can be send out as a reminder to human beings in light of the current climate changes happening all around. Climate change is an ongoing and a slow process and it can be seen throughout the history of the earth from the Paleozoic era to the Ice age to the current day. In the past climate changed over millions of years and was due to natural phenomenon so the species had ample time to evolve and adjust to the change. But the recent change in earth’s atmosphere has been rapid. In the last two decades climate change has occurred exponentially due to human activity.
Although CO2 is absorbed and emitted naturally through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange, atmospheric CO2 emissions have increased nearly 40% from pre-industrial times. The increase is largely due to human activities that include the burning of fossil fuels and changes in land use that require deforestation (EPA). The effects of global climate change on the environment are very real and already observable. In the past, some of the things scientists had predicted that global climate change would cause were loss of sea ice, accelerated sea level rise and longer, more intense heat waves. We are witnessing those changes now.
Global warming is caused by pollution eating away at the ozone layer of the atmosphere, as well as greenhouse gases trapping heat. The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. (Riebeek 2) Many scientists believe that the effects of global warming will greatly impact the planet. Direct effect of Global Warming is increased heat on Earth then it will cause ice on poles to melt, leading to rising sea levels and land loss, because many areas will be under water. Besides that, many events of catastrophic weather will occur, such as droughts, floods, volcanic, tsunamis and earthquake.
Global Climatic Changes Introduction: Climatic change is a lasting change in the weather patterns around average conditions. Certain factors like global warming, greenhouse effect, biotic processes are some of the reasons for global climatic change. The average global temperatures have changed and the precipitation patterns as well. Over the past century human activities led to increase in the emission of heat trapping gases like carbon dioxide. The average earth’s temperature has risen by 1.4° F and it is also projected to rise about another 2-13.5° F in the coming decades.
It is so compellingly evidential that the concentrations of these gases in the atmosphere have increased and still increasing rapidly, that climate change is occurring, and that most of the recent change is almost certainly due to emissions of greenhouse gases caused by human activities. Further climate is inevitable; if emissions of greenhouse gases continue unabated, future climate changes will substantially exceed those that have occurred so far. There remains a range of estimates of the magnitude and regional expression of future change, but increases in the extremes of climate that can adversely affect natural ecosystems and human activities and infrastructure are expected. However this doesn’t have to be the answer, do your part, make a difference, it’s time we put a stop to this, our world is dying, help prevent climate change. There is a solution.
