BackgroundGlobal warming has become a prominent and sustained issue. The controversy revolves around the causes, nature, and consequences of this phenomenon. Since the mid-20th century, people have been concerned about the warming trend of the planets temperature. Is it unprecedented with the normal climatic variations? Within the last decade, questions surrounding its nature have been partially answered by science and technology. The questions now are more about prevention and consequence.
What is Global Warming?Global warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. Over the last 100 years the average temperature of the air near the Earth's surface has risen a little more than 1 degree Fahrenheit. While that number doesn't seem all that much, scientists believe it is responsible for the conspicuous increase in storms, floods, and raging forest fires we have seen in the last decade.
Any questions about global warming surround what is known as the greenhouse effect. As seen from space, our atmosphere is but a tiny layer of gas around the huge bulky planet. Just like the glass roof and walls of the greenhouse the sun enters through the glass and heats up the inside. In turn, the glass panels trap the warm here in this results in a surface temperature increase.
Scientists believe global warming is attributed to the rising levels of carbon dioxide and other gases from the use of non-environmental friendly energy sources like the burning of fossil fuels. Moreover, it is believed that this phenomenon is related to the way we are living.
This debate is part of the Global Warming series. Other debate topics in this series include:
|•||Is global warming real?|
|•||Is global warming caused primarily by human activity?|
|•||Can global warming be stopped?|
|•||Should the government be responsible for regulating emissions?|
|•||Is Al Gore biased when it comes to global warming?|
Yes, global warming is a serious threat
Climate Change ExistsAll European member states ratified the 1997 Kyoto protocol and many European countries had already been taking action to reduce greenhouse gas emissions prior to 1990. A report from the intergovernmental panel on climate change (IP CC) revealed that leading climate scientists are now 90% sure that human activity is heating up the planet.
The finding that the climate has warmed in recent decades and that this warming is likely attributable to human influence has been endorsed by every national science Academy has issued a statement on climatic change, including the science academies of all the major industrialized countries. At present, no scientific body of national or international standing has issued a dissenting statement.
Danger of Climate Change is Real and DevastatingNumerous long-term changes in climate have been observed. These include changes in Arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather including droughts, heavy precipitation, he waves and the intensity of tropical cyclones
These changes in weather patterns and changes in the balance of Earth's ecosystem can have a devastating effect on people's lives.
Action RequiredDoing Nothing Is No Alternative. To Be Able to Make Investments in Clean and Low Carbon Technologies, We Need Stable Political and Regulatory Frameworks. These investments can not only come from the public sector; private investments have to play a role if we want to build a low carbon economy.
No, global warming is not a serious threat
Skeptical Scientists AboundThe appearance of overlapping groups of skeptical scientists, commentators and think tanks in seemingly unrelated controversies results from an organized attempt replace scientific analysis with political ideology.
No Proof that Climate Change is DevastatingThere is no conclusive evidence that climate change is happening; the changes in measure temperatures are part of the natural cycle; even if the changes are human induced, the scale is not sufficiently large to make changes beyond sensible measures; the economic impact of making substantial cuts to greenhouse gas emissions on the scale suggested Is too large; the predictions of global warming are based on computer models, but those models don't include such highly correlated data as sunspots in global temperature changes.
Natural CausesClimate change may be caused by natural phenomena such as volcanoes and the reversal of Earth's magnetic field.
