The Cost Of Denying The Reality Of Climate Change

With so much misinformation surrounding climate change and global warming  from science deniers, the facts can often be misunderstood or misconstrued.

Global warming is a serious issue but many people may not realize the impact that climate change has had on the world.

Top 10 global warming facts


1. 90% of the global warming has been caused by human factors since 1950. This data was just released by the UN in a recent report on climate change. This panel studied the main components of climate change to determine that humans had caused the majority of the climate change.

2. The hottest decade spanned from 2000-2009. During this 10-year time period, the temperature was a degree hotter than in 1970. While this may seem like a small amount, even a small temperature increase is significant in global matters. frequently asked questions on climate change

3. Global warming facts,the year 2011 saw the most CO2 dumping at the rate of about 1000 tons/second into the air. Factories were the highest causes of CO2 emissions. The numbers for 2012 are also expected to be high.

4. The sea level has risen approximately 1 inch. Scientists predict that at the current rate, the sea level rising will become a serious problem by the year 2100.

5. China is a worse offender than the US in CO2 emissions. They emit about 40% more CO2 than the US currently. Since China is known for their factories and as a major producer of goods, lowering their amount of emissions has been uneffective so far.

6. The CO2 level is currently the highest it’s been in 650,000 years. There has been an 11% increase since 1950. The rate at which CO2 is rising is cause for concern for many scientists and other people in the environmental field.

7. Climate change has had a huge change on the earth. For example, when earth was only 9 degrees cooler, the ice over New York City was over 2000 feet thick. There is a chance that the Earth will be 9 degrees hotter by 2100. This change would have a huge impact on the current landmass.

8. Global warming facts, Reducing the CO2 emissions by 20% would be incredibly cheap and only cost about 16 cents per person every day. By taxing companies that produce large CO2 emissions, this would encourage lessening of the emissions.

9. One of the largest obstacles to climate change strategies is that the US and China must cooperate. If these two countries are able to band together and start setting an example with climate change, Europe, Japan, India, and Australia would also go along with the policies set and begin changing their methods as well.

10. The current tactics are not working. Unfortunately, caps are usually being given to some of the poorest countries instead of trying to cap emissions in wealthier countries that produce more emissions. Caps are not also the only way to counteract climate change. There needs to be a reform in the way that scientists approach the public with climate change and the way that countries view environmental policy.

These 10 global warming facts reflect some of the current concerns about the planet and how it is changing. In order to combat these changes, new laws and limitations will need to be made as well as global environmental policies


 

Irrefutable Evidence Of Climate Change

Climate change can be described as the lasting and significant change in the distribution of weather patterns in decades to several million years time period. It can also be viewed as the change in the average weather conditions. Generally, climatic change results from changes in oceanic processes, solar radiation variation, volcanic eruptions and plate tectonics as well as natural world alteration by human activities. Usually, climate change is used while describing the effects due to human activities. Such activities lead to global warming.

The evidence of climate change is typically obtained from ice cores, analysis of stable isotopes as well as other sediments, temperature profiles of boreholes, sea level records, glacial processes and flora and fauna records.

Glacier shrinking has been used as evidence of climate change.

glacier melting

Since the 1970s, there has been a compilation of a global glacier inventory. Initially, aerial photographs were used to compile the inventory but presently, the compilation is being done via satellites. From the inventory, it can be demonstrated that there has been a significant shrink in glaciers worldwide with only 445, 000 sq. km of ice cover remaining. The inventory shows that there were strong retreats of ice in the 1940s, but they recovered in the 1970s to eventually start retreating from the 1980s to present. Ice sheets are also retreating. In the years 2002-2006, Greenland lost approximately 150-250 cubic km. of ice every year with Antarctica losing 152 cubic km. between 2002-2005.

Loss of Arctic Sea ice is another evidence of climate change. While almost all of the Antarctic sea and the Southern Oceans ice would melt and reform each year, the Arctic sea would lose very little ice cover. However, it is presently approximated that the Arctic Sea is losing its ice at the rate of 11.5% per decade when compared to the 1979-2000 average ice cover.Rise in sea level is also another evidence of climate change due to increased temperatures that have melted vast areas of ice. The melt finds its way into the oceans raising their levels. For instance, it has been proven that the world sea level rose by approximately 17 centimeters during the last century.

On the other hand, this rate in sea level rise is almost double in the last decade alone. It’s during that period that we have experienced some of the hottest years on record.Increased global temperatures that have converted large areas that were initially viable for agricultural activities into deserts. Since the 1880s, global surface temperatures have been on the rise. The trend gained pace in the 1970s, with twenty of the warmest years falling between 1980s and present. This has greatly affected vegetation and in turn, the organisms that rely on the vegetation. Similarly, it has led to an increase in ocean temperatures with results showing an increase of 0.302 0F in the top 700m since 1969. This has in turn led to sea ice melting that subsequently raises the sea level.Extreme weather has been demonstrated recently. The recent evidence of climate change are the frequent hurricanes, hurricane Sandy being the most recent one. There have also been very hot times and intensive rainfalls as well, causing massive floods that have forced the government to evacuate cities.


 

The Cost Of Climate Change

Global warming and climate change refer to the continued rise in the earth’s average temperature, as well as that of the oceans. This climate change phenomenon that started in the late 19th century. Since then, the surface temperature of the earth has risen by approximately 0.8 0C, with approximately two-thirds of this rise happening from the 1980s onwards. Research has undisputedly proven that this rise in temperature has been due to greenhouse gases that result from activities like fossil fuel burning. Rampant deforestation has also contributed to a surge in greenhouse gases.

On the other hand, this rise in the planet’s temperature is already manifesting its effects on the planet. Unless the obvious facts due to global warming are quickly addressed, the world will, and is already suffering from the effects of rapid climate change. Below are some of the facts about global warming;Carbon dioxide is the primary greenhouse that causes global warming. The United States is the biggest producer of carbon dioxide, and thus the biggest contributor to global warming. Recently, China’s carbon dioxide output has been on the rise and it’s projected that by 2016, China will be the biggest carbon dioxide emitter in the world. These are the biggest economies in the world that heavily rely on burning fossil fuels. 20% of emitted carbon dioxide is from cars engines while burning gasoline.

The biggest percentage, on the other hand, is from power plants that burn fossil fuels to generate electricity. In addition to carbon dioxide, water vapor is contributing to climate change. In fact, water vapor alone contributes over 90% of the greenhouse-warming-effect.More and more carbon dioxide is being pumped into the atmosphere, with an addition of 6B metric tons since 1990. Carbon dioxide takes about 100 years to completely disperse in the atmosphere. There, therefore, needs to be immediate political will on world economies on the use of environmental-friendly fuels so as to save the planet’s biodiversity.The year 1997 had the highest record of carbon dioxide in the atmosphere. Since then, the world has experienced some of the warmest years on record. For instance, 2005 was the warmest year ever with 1998 and 2007 being the second warmest years on record. Similarly, the top eight warmest years in history have been between 1998 and present. In addition, the mean temperatures in Arctic climates of Russia, Canada and Alaska have increased by two times the global average. All this is due to the effects of greenhouses emissions and deforestation.

glacier shrinking stats

Recently, there has been massive ice glacier melts, especially on the North Pole. A continued trend in this direction will lead to a rise in the sea level, with projections indicating a 7-23 inches rise by the end of the century should the warming trend continue unchecked. This will not only affect the millions of people living within the coastlines, but wildlife too. At present, the polar bear is an endangered species due to the effects of global warming.

In 2007, some residents of Tegua Islands had to be evacuated due to the rising sea level and associated climate change flooding patterns.As of 1950s, the Arctic sea ice has diminished by approximately 15% while the mean annual ice duration on the northern rivers and lakes has diminished by 2 weeks. On the other hand, earth lost ice approximated to be about 890 cubic miles between 1961 and 1997. Similarly, Montana’s Glacier National Park had 150 glaciers in the 1910s. Presently, only 27 glaciers remain.Climate change is creating more desserts in the world today. This has a direct effect on the food security of the world as well as biodiversity. For instance, 25% of Australia’s crop production in 2007 was lost to desertification.

Developing countries have to rely on food aid due to failed rains in their countries. Similarly, species are likely to go extinct, especially with the rampant deforestation that destroys their natural habitat, if climate change is unchecked. The polar bear is a good example of a species in danger of extinction due to climate change.Recently, we have witnessed the adverse economic and health effects climate change can bring. From frequent wildfires, floods in Haiti, earthquakes in Japan, hurricanes in the U.S; with hurricane Sandy being the latest, to failed rains in Africa creating droughts. These extreme weather patterns are due to global warming.Its approximated that over $20 trillion will be used in research of reversing or slowing down global warming in 25 years to come.
