The rapid rise in greenhouse gases is a problem because it is changing the climate faster than some living things may be able to adapt. Also, a new and more unpredictable climate poses unique challenges to all life. Historically, Earth's climate has regularly shifted back and forth between temperatures like those we see today and temperatures cold enough that large sheets of ice covered much of North America and Europe. The difference between average global temperatures today and during those ice ages is only about 5 degrees Celsius (9 degrees Fahrenheit), and these swings happen slowly, over hundreds of thousands of years. Now, with concentrations of greenhouse gases rising, Earth's remaining ice sheets (such as Greenland and Antarctica) are starting to melt too.
Also, the heat is causing much more, untamable wildfires to occur, which sends thousands of people with respiratory-related illnesses to the hospital every year, such as those who suffer from bronchitis, asthma, and chronic lung disease. Of all these addressed health effects due to climate change, every single one has a direct relation to the global temperature increase, as does the swelling of our oceans and natural occurring water sources across Earth’s
Climate change has been occurring over the decades but it is just getting worse and more greenhouse gases are getting trapped in the atmosphere and trapping heat energy from the sun along with it. If humans are so small and can create a mess so big we can clean it up too because it is evident that humans have caused an increase in chemicals and pollution that has altered the chemical composition of the atmosphere which ultimately causes the climate change we see
The global climate change and its consequences are leaving a bad impact on the countries to face poverty and hotter temperatures. Climate change impacts include temperature rise, greenhouse and carbon dioxide gas emissions, erratic rainfall, salinity intrusion, the rise of floods, cyclones, storm surges and draught, ice sheets melting which will seriously affect the agriculture, and the world. Researchers agree that climate change is a fact.Temperatures have been increasing
The effects of the climate change are undeniable in the scientific research. The Intergovernmental Panel on Climate Change and other meteorological organizations measures the temperature of the earth on the daily basis and has indicated the potential increase. Furthermore, the dramatic decline in ice and glaciers in the North and South Pole verify the rising temperature and its impact on the sea level. It should be noted that from last decade, the sea level has been increased due to melting of the ice that ocean currently pose a threat (Shrestha, Babel, & Pandey,
Of course, land and ocean temperature is not the only way to measure the effects of climate change. A warming world also has the potential to change rainfall and snow patterns, increase droughts and severe storms, reduce lake ice cover, melt glaciers, increase sea levels, and change plant and animal behavior http://news.discovery.com/earth/global-warming/10-signs-climate-change-is-already-happening-130422.htm http://news.bbc.co.uk/2/hi/in_depth/629/629/6528979.stm#arctic Some of the Key statistics / noticeable changes can be given as follows: 1) The rate of warming is unprecedented in atleast 11,000 years 2) The hottest decade on record keeps on changing : global mean temperatures have increased by approximately 1.33 degrees Fahrenheit (0.74 degrees Celsius) over the past century 3) Arctic Sea ice is in a “Death Spiral” : The extent of summer sea ice covering the Arctic Ocean is now decreasing by a rate of about 13 percent per decade, compared to the 1979-2000 average 4) On average, since 1993, the sea has been rising by 3.18 mm per year, primarily as a consequence of thermal expansion due to warming, and to the melting of ice
These individual events obviously are not concrete proof, but they contribute to a larger pattern (Nye and Powell 19-33). Generally, Earth’s climate changes slowly at its own pace (Nkemdirim566+). The CO2 levels in the atmosphere have increased dramatically since the industrial age, and that is part of the problem. The rate humans add to the carbon levels is causing the greenhouse effect to get stronger and stronger. The greenhouse effect is closely associated to global warming.
“...increase in atmospheric carbon dioxide (CO2) levels change the ocean chemistry and threaten the entire marine food chain” (Brennan 1). If in the near future a solution does not arise, we could potentially harm and sabotage the future of these species. A major component that could help with our rising sea levels is by using effective ways to produce clean energy. With doing so, this could theoretically slow down the negative effects of global warming. The critical components that human-induced actions have impacted include damaging oceans, destroying wildlife habitats, destruction of coral reefs, and increased periods of drought (Brennan 1).
Today, based on the topic environment, I am going to discuss on the cause and effect of global warming that is happening on our mother earth. What is global warming? Global warming is the term used to describe the gradual increase of the average temperature on the Earth’s atmosphere and the oceans, which is believed to cause climate change on earth permanently. Based on scientific research on climate change due to global warming, the average temperature rise is between 0.4 to 0.8°C for the past 100 years. Scientists also predicted that the average temperature could increase between 1.4 to 5.8°C by the year 2100.
It is easy to observe that the effect of global climate change on the Earth. For example, the rises of sea levels, glaciers, and polar ice caps are melting; numerous animals are emigrating to find other places to exist; trees are in bloom sooner. Scientists have confirmed that the temperature will keep on rising up for the next decades because of human activities in the industry (Alina). One of the biggest problems facing us now is global warming. It not only affects animals and plants but also the human population, which is indeed scary (Markham).
