How is Affecting Global Warmin to the Earth

In this essay I will be discussing the issue of Global Warming and I will explain both points of view about this topic, because this is a very interesting topic to discuss for that reason this is affecting to everyone in the world and the future generations.

In my opinion, Global Warming is affecting all of us, all the contamination, the thermoelectrics, the buses and all that I mention before are affecting the enviroment and killing us. In addition the Union of Scientists say that "CO2 puts us at the greatest risks of irreversible changes if it continues to accumulate unabated in the atmosphere".

First, the problem is that this issue is not very well informed. I think that this topic can be more spread out with lectures, activities about the Global Warming, do activitieson schools and also on universities. Secondly, and other problem is that the Global Warming it's increasing in the last years, this is produced by the increase of temperature and the increase of CO2 in the atmosphere. According to the Union of Concerned Scientists in the lasts centurys the temperature increase 2 degrees Celsius and say that on the 2001 - 2010 decade the temperature increase 0,7 degrees Celsius.

On the other hand, I think that if we eliminate the thermoelectrics industries and the hydroelectrics, the Global Warming can decrease, but if this industries disappear all the houses, hospitals, schools will would need and other thing to produce energy and on this times are still very expensive, and not all the people can't affort it. The junkscience.com state "yet U.S. taxpayersare subsiziding wind energy at a cost of $12 billion a year", and this is why a regular person can't pay for a eolicenergy.

In conclution, this issue needs to be controled now, whit new kinds of energy, more information about how they can help the enviroment, because if this topic stay in increase the future generation will have problem in helth, drougth and also problems in the skin pruced by sunligth.

6. 1. Global warming is the increase of Earth's average surface temperature due to greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
7. 2. Greenhouse gases keep heat close to the earth’s surface making it livable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal).
8. 3. With the start of industry in the 1700's, humans began emitting more fossil fuels from coal, oil, and gas to run our cars, trucks, and factories. By driving a “smarter” car, you will not only save on gas, but help prevent global warming.
9. 4. There is more carbon dioxide in the atmosphere today than at any point in the last 800,000 years.
10. 5. In total, the U.S. emits approximately 6 billion tons of carbon dioxide every year. 40% of that comes from power plant emissions alone.
11. 6. The NRDC (Natural Resources Defense Council) proposed the Clean Air Act to cut power plant emissions by 26% in the next 7 years.
12. 7. Since 1870, global sea levels have risen by about 8 inches.
13. 8. Consequences of global warming include drought, severe hurricanes, massive fires and melting of the polar caps.
14. 9. Heat waves caused by global warming present greater risk of heat-related illness and death, most frequently among patients of diabetes who are elderly or very young.
15. 10. According to the U.S. Global Change Research Program, the temperature in the U.S. has increased by 2 degrees in the last 50 years and precipitation by 5%.

11. 11. Global warming puts coral reefs in danger as warmer water increases the possibility of coral diseases and the rising sea levels makes it more difficult for coral to receive adequate sunlight.

"Observational evidence from all continents and most oceans shows that many natural systems are being affected by regional climate changes, particularly temperature increases." –Intergovernmental Panel on Climate Change (IPCC), 2007

Explore the signs of global warming on this map or Google Earth. The evidence of climate change includes heat waves, sea-level rise, flooding, melting glaciers, earlier spring arrival, coral reef bleaching, and the spread of disease.

The greatest concentration of global warming indicators on the map is in North America and Europe because that is where most scientific investigation has been done to date. As scientists focus increasingly on fingerprints of global warming in other regions—from Russia to Antarctica and Oceania to South America—the evidence they find will be added to the map.

Scientists project that unless emissions of heat-trapping gases are brought undercontrol, the impacts of climate change are likely to increase.

Global Warming Causes

Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. See the pie chart for a breakdown of heat-trapping global warming emissions by economic sector.

Global Warming Is Urgent and Can Be Addressed

CO2 survives in the atmosphere for a long time—up to many centuries—so its heat-trapping effects are compounded over time. Of the many heat-trapping gases, CO2 puts us at the greatest risk of irreversible changes if it continues to accumulate unabated in the atmosphere—as it is likely to do if the global economy remains dependent on fossil fuels for its energy needs. To put this in perspective, the carbon we put in the atmosphere today will literally determine not only our climate future but that of future generations as well.

Substantial scientific evidence indicates that an increase in the global average temperature of more than 3.6 degrees Fahrenheit (°F) (or 2 degrees Celsius [°C]) above pre-industrial levels poses severe risks to natural systems and to human health and well-being. The good news is that, because we as humans caused global warming, we can also do something about it. To avoid this level of warming, large emitters such as the United States need to greatly reduce heat-trapping gas emissions by mid century. Delay in taking such action means the prospect of much steeper cuts later if there is any hope of staying below the 3.6°F (2°C) temperature goal. Delayed action is also likely to make it more difficult and costly to not only make these reductions, but also address the climate consequences that 
occur in the meantime.

The Consequences of a Warming World

Over the last century, global average temperature has increased by more than 1°F (0.7°C). The 2001-2010 decade is the warmest since 1880—the earliest year for which comprehensive global temperature records were available. In fact, nine of the warmest years on record have occurred in just the last 10 years. This warming has been accompanied by a decrease in very cold days and nights and an increase in extremely hot days and warm nights. The continental United States, for example, has seen record daily highs twice as often as record daily lows from 2000 to 2009. While the record shows that some parts of the world are warming faster than others, the long-term global upward trend is unambiguous.

Of course, land and ocean temperature is only one 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.

Regional Actions Add Up to Global Solutions

We encourage you to visit the solutions section of this web feature to find out how you can take action to slow the pace of climate change and help minimize the harmful consequences described in the hot spots!

Any action to reduce or eliminate the release of heat-trapping gases to the atmosphere helps slow the rate of warming and, likely, the pace and severity of change at any given hot spot. Local sources of carbon emissions vary from region to region, suggesting that solutions are often decided at the community level. The Climate Hot Map points to regional examples of climate-friendly energy, transportation, or adaptation choices. Some regions, however, must rely upon global solutions such as international agreements to reduce the carbon overload in the atmosphere that threatens them. Small 


islands, for example, are a paltry source of carbon emissions and yet are disproportionately affected 
by the consequences of global carbon overload as accelerated sea level rise threatens the very existence of low-lying islands.

Individual, regional, and national actions can all add up to global solutions, slowing and eventually halting the upward climb of CO2 concentrations in the atmosphere.
