The Effects of Global Warming

July 3, 2010 | By In Global Warming | Comments(0)

When you hear about the effects of global warming it is important to understand that the effects we are experiencing today are moderate compared to what the future will see if we do not take preventative action. Over the next century researchers and environmental professionals are stating that the effects of global warming will continue on a constant inclined curve. Temperatures heating up a little bit each decade until the earth’s temperatures reach the sweltering levels that we experienced in history. Scientists believe that the earth’s temperatures will rise between 2-9 degrees Fahrenheit by 2050.

The Arctic and the earth’s northern latitudes will feel the most of the effects of global warming as they continue to escalate. As the Arctic packs and glaciers begin to melt from the increased temperatures the tundra and seas surrounding the areas will continue to absorb the warmth which was once reflected back into space. Climate models show that if temperatures throughout the rest of the world rise to 3 degrees Fahrenheit they will more than likely rise to at least 7 degrees Fahrenheit in the Arctic. From this the oceans throughout the world will become full with melting glaciers and ice from the Arctic likely to rise by at least 3ft.

As the temperatures continue to rise this will force the ocean to evaporate quicker and therefore more rainfall will be experienced. The problem with this effect is that the rainfall may hit areas of the world which do not need it at all causing massive floods and monsoons. Subtropical areas like India are expected to be the target of this particular effect of global warming. On the other hand it is safe to say that droughts are going to be more of a problem than flooding.

There are predictions that the future effects of global warming may have its benefits as well. In the northern part of the world such as Canada, the warmer temperatures will mean longer growing seasons and more rainfall. This of course then will put an end to any food shortage that may be occurring and provide a new sense of prosperity to countries throughout the world which have been struggling to survive.

Many of the changes and effects listed above are already taking place today on a smaller scale of course. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Amounts and patterns of precipitation are changing as well but only slightly in comparison to what has been predicted for the future. Changes in temperature and precipitation patterns increase the frequency and intensity of other extreme weather events such as floods, droughts, heat waves, and tornadoes.

Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows and species extinctions. As a further effect of global warming, diseases like malaria are returning into areas where they have been extinguished earlier. This is only the beginning of the effects global warming can have on our earth. As the greenhouse gases continue to increase and enter the atmosphere these effects are only going to increase in severity making it harder and harder to maintain our quality of life.

Many people find it hard to believe that the effects of global warming can become as severe as scientists are predicting but the patterns support these theories. When you read studies comparing today’s weather to weather 20years ago there are already signs proving the effects of global warming. Pay attention to the weather today and the severe weather being reported from all over the world and you will begin to see the effects within your own life as well.

We can all do our part to reduce the amount of greenhouse gases within our atmosphere. No matter how small the act might be (saving electricity, conserving fuels, etc) every action makes a difference when we are all making these eco-smart decisions. There are no doubts that the effects of global warming are only going to persist and increase if we do not do something today. The fact is that even if greenhouse emission gases were completely eliminated today it will still take years to eliminate the threats of global warming. This is why it is so important to do what we can today!

Exploding The Global Warming Myths

June 23, 2010 | By In Global Warming | Comments(0)

Are you a believer of Global warming or not? Or are you one of the cynics yet to be convinced? Well both have a part to play in the Global Warming arena debate. The whole issue is surrounded by facts and figures but when these facts and figures are looked at it is very difficult to prove them with science, so you end up with hearsay.

Global warming from our point of view is the increase in the average temperature of the Earth’s near-surface air and oceans.

When you observe all the different global warming myths that are published in various publications, online, TV, and radio you will understand the issue with conflicting information. Because of these global warming myths come in many forms it is essential to understand the causes of global warming, and the facts attached to those myths.

MYTH: Water vapour is the most important, abundant greenhouse gas. So if we’re going to control a greenhouse gas, why don’t we control it instead of carbon dioxide?

FACT: Water vapour does trap more heat than carbon dioxide (CO2), but as CO2 levels increase in the atmosphere, they lead to warmer conditions, which lead to more water vapour in the air, which leads to even warmer conditions, thus a never ending cycle. Because of this relationship between CO2, water vapour and climate, to fight global warming nations must focus on controlling CO2.

MYTH: Global warming reduces as the ozone hole shrinks.

FACT: Global warming and the ozone hole are two separate issues.

MYTH: Global warming is not occurring due to some glaciers and ice sheets are expanding and not shrinking.

FACT: In most parts of the world, the shrinking of glaciers and ice caps have been dramatic. The best available scientific data indicate that Greenland’s massive ice sheet is shrinking.

MYTH: So what if global warming is a problem, trying to fix it will affect American industry and workers.

FACT: A well thought out trading program will harness American ingenuity to decrease heat-trapping pollution cost-effectively, jumpstarting a new carbon economy.

MYTH: The cold winters and cool summers that have been happening of late are not the effects of global warming, and are infrequent events.

FACT: While it is true that different areas of country’s have experienced some colder winters here and there, between them the average temperature has ben on the up.

MYTH: We can adapt to climate change. Civilizations have survived droughts and temperature shifts in the past.

FACT: Although it is true that the human race has survived an onslaught of drought and prolonged warmth along with the bitter cold and more, entire societies have collapsed from dramatic climatic shifts.

MYTH: Global warming along with extra CO2 will be beneficial, they reduce cold related deaths and stimulate crop growth.

FACT: Any beneficial effects will be far outweighed by damage and disruption.

MYTH: Global warming is just part of the worlds natural cycle. The Arctic has warmed up in the past as it is doing now.

FACT: The global warming we are experiencing is not natural. People are causing it.

While the global warming myth story is interesting, it does reduce the impact of the facts. But as they say “Truth is stranger than fiction.” The many myths on global warming doing the rounds are based on global warming statistics, just with a different view point.

It is always best, as with everything, to look at the global warming myth with an open mind. There is always two sides to every coin, so explore both before making your full opinion.

Perhaps this article on global warming myth with strike a chord with you and will inspire further reading into the subject.
