The Important Differences Between “Climate Change” and “Global Warming”

Important ReputationProfessor.Com Differences By: James Nash

Many people in the media (and elsewhere) use the terms “climate change” and “global warming” interchangeably, as if they were the same thing. But there are differences between the meanings of the two terms.

Getting a better handle on the definitions of and differences between “global warming” and “climate change” will help us understand why the threat caused by continued warming of the planet is so serious.
Planet Earth’s current warming trend is based largely on natural warming and cooling cycles that have been happening for eons; as well as human-caused additions to greenhouse gases, which are boosting the atmosphere’s ability to trap heat in the biosphere. Minor factors like an overall increase in the sun’s solar intensity play a smaller role.

While greenhouse gases are an essential component of a livable planet - they’re what keep Earth from being a lifeless ball of ice - humans are causing greenhouse gas levels to increase so quickly that it’s causing the average global temperature to rise much faster than it would naturally. This warming is predicted to lead to a variety of negative effects, including:

1) Melting (and possible disappearance) of glaciers and mountain snow caps that feed the world’s rivers and supply a large portion of the fresh water used for drinking and irrigation.

2) A rise in sea levels due to the melting of the land-based ice sheets in Greenland and Antarctica, with many islands and coastal areas ending up more exposed to storm damage or even underwater.

3) Increasingly costly “bad weather” events such as heat waves, droughts, floods, and severe storms.

4) Lowered agricultural productivity due to less favorable weather conditions, less available irrigation water, increased heat stress to plants, and an increase in pest activity due to warmer temperatures.

5) Increases in vector-borne infectious diseases like malaria and Lyme Disease.

6) Large numbers of extinctions of higher-level species due to their inability to adapt to rapidly changing climate and habitat conditions.

The first two of these effects are mostly related to increasing average temperatures. Items 3-6 are related to heat too, but also playing a role are non-temperature factors - i.e. “climate-change factors.”

Climate change is about much more than how warm or cool our temperatures are. Whereas “global warming” refers to increasing global temperatures, “climate change” refers to regional conditions. Climate is defined by a number of factors, including:

1) Average regional temperature as well as day/night temperature patterns and seasonal temperature patterns.

2) Humidity.

3) Precipitation (average amounts and seasonal patterns).

4) Average amount of sunshine and level of cloudiness.

5) Air pressure and winds.

6) Storm events (type, average number per year, and seasonal patterns).

To a great extent, this is what we think of as “weather.” Indeed, weather patterns are predicted to change in response to global warming:

1) Some areas will become drier, some will become wetter.

2) Many areas will experience an increase in severe weather events like killer heat waves, hurricanes, flood-level rains, and hail storms.

It’s tempting to think that all of these changes to the world’s climate regions will average out over time and geography and things will be fine. In fact, colder climates like Canada may even see improved agricultural yields as their seasonal temperatures rise. But overall, humanity has made a huge investment in “things as they are now, where they are now.”

Principles of Greenhouse Effect

ReputationProfessor.Com Principles of Greenhouse By: Henry White.

The emission of infrared radiation by the atmosphere results in the warming up of the surface of a planet. This process is called the greenhouse effect. In other words, certain gases in the atmosphere trap the solar energy so that the earth experiences a considerable rise in temperature. These gases include carbon dioxide, water vapor, methane, nitrous oxide etc. and they are known as green house gases. The absence of these gases will make the heat escape back into the space which will make life on earth impossible. Green houses make use of this mechanism.

Greenhouses are used to grow plants, especially in the winter. Most green houses resemble a small glass house. Here, it is the glass panel that plays the role of the greenhouse gases. The glass panels of a greenhouse allows the entrance of solar energy in the form of heat and light, but won’t let it escape. This raises the temperature inside the glass house and provides suitable atmosphere for the growth of the plants inside.

In the case of atmosphere, our earth receives energy from the sun. Once absorbed, this energy is sent back to the atmosphere. While doing so, a major portion of the energy gets absorbed by the greenhouse gases and warms up our planet. Green house effect, if enhanced considerably too can deny existence as it would heat up the earth than usual.

The Perks of Global Warming

Marya Mannes once wrote, “The earth we abuse and the living things we kill will, in the end, take their revenge; for in exploiting their presence we are diminishing our future.” Obviously Ms. Mannes preferred the status quo - health, sanity, logic, blah, blah, blah. Why? Green House Roulette is so much more intriguing.

In the country, weather affects everything. For five years western South Dakota has been gripped by drought. Water and hay are vanishing. Farms and ranches are blowing away. While the government bails out victims from hurricanes and says, ‘South Dawho?’ our cattle are pissing dust mites. Fortunately, things are looking up.

There is some good news. Those pesky glaciers are finally melting off! Last year an eight-nation report estimated an area of Arctic icepack the size of Texas and Kansas is gone. For those who are geographically impaired, that is an area bigger than a breadbox.

At first, news of devastating global climate change might seem a bit of a bummer. Then I read an LA Times article and had a change of heart. The article began with the usual gloom. Greenland’s ice cap is melting. Our coasts will flood from rising seawater. Inuit hunters are falling through thinning ice. Melting glaciers are changing ocean temperature and salinity contorting the jet stream, resulting in altered weather patterns worldwide. Multitudes of species are dying off . . . It was disheartening to read.

Then I got to the article’s final paragraph. Bam! My faith was restored. Here the Times pointed out the perks of global warming. Seriously, the article actually ended saying: “The report is not all gloomy. A warmer Arctic could increase the number of some species, such as Arctic char, a fish. It could extend the growing season for wheat in Canada and open up now-treacherous sea routes, such as the Northwest Passage and the Northern Sea Route, which parallels Russia, for shipping and resource exploration.”

Three cheers for the LA Times! It’s true! All is not gloomy. With that glorious bit of sunshine pumped straight up my ski bibs, I was able to see things in a whole new light. I started thinking of other advantages to global warming. Soon you will agree that people from all walks of life will benefit.

For starters, Inuit Hunters will benefit! Once Inuit have nothing left to hunt there will be no need for them to risk falling through thin ice. Plus, by needing food they will be ripe for a floating (pontoons, not ice) Arctic Super Wal-Mart. “Go get ‘em, Sam.”

Boat owners will benefit! Not only will there be smooth sailing through the formerly bothersome ice of the Northwest Passage, but each summer, cruise ships will be able to run tourists straight up Bourbon Street in New Orleans.

Scuba Divers will benefit! There will be no more burning coral cuts. In fact there will be no more coral. Once all the reefs are gone, divers can pack away first aid kits and dive straight in. A little silt never cut anyone.

Canadian Wheat Farmers will benefit! You see, there is a 10% decrease in yield of corn from Midwest crops for every degree of global warming. No worries though, now wheat can take the place of corn. Think about all those scrumptious Wheat Dogs at the ball game. How about popped wheat with butter at the movies or steaming wheat on the cob? All scream ‘yummy’ to me.

While it is a bit ironic that ethanol is made from the corn crops global warming devastates, I am sure some aspiring chemist will rise to the challenge of developing ‘Wheatanol.’ Imagine Canuck Wheat Farmers having more influence than the Saudi Royal Family.

Dune-Buggy enthusiasts will benefit! The Dakotas will soon reopen for your 4-wheelin’ pleasure. Join the Mount Rushmore Nose Climb on July 4th! It will be a bugger of a challenge!

Eco-Tourism Operators will benefit! Companies could offer new “Emaciation Tour Packages.” Tourists get closer photos of polar bears and whales when they are too lethargic from starvation to meander away. In addition, long treks to Inuit villages can be avoided once they are forced to beg on the streets of Nome (or cashiering at Wal-Mart).

Finally, the next generation of Bush family politicians will benefit! Once again they can avoid addressing campaign issues, this time by distracting dehydrated voters with witty campaign phrases like; “No Kyoto Pact-No Ice Pack,” or “Dead Seals Never Flip-Flop,” even promising “No Char Left Behind.” Not to mention offering new SPF 800 tax credits.
