Is global warming really a problem?

Question

I like summer fashons better, especially the swimsuits! Also, think how much we will all save on our heating bill. Then If my furnace doesn't run won't the planet cool again like it did in the 1970 or the 1300s?

Answer 1

I hear ya, maybe girls would start wearing bikinis more often. There should be a new global warming dress code that says hot girls are allowed to wear bikinis in school, the workplace and anywhere else in public.

Answer 2

Yes this is a problem, and global warming does not just relate to comfort (by the way, I live in the middle/north east coast of Australia and I can say that I don't like the idea of the climate becoming hotter).Yah, blah blah blah, ice caps melt, blah blah, yadda yadda yadda, some scientists say that as a result of the ice caps melting and the currents in the ocean slowing down, we will plunged into another ice age. by the way, global warming has nothing to do with the ozone layer.

oh and wind power is not the answer, I read somewhere that with the technology we have now, it would take 20,000 wind turbines to power a city like Paris. You shouldn't rely only on that documentary called "the great global warming swindle" to say that global warming is rubbish. Whatever people say about global warming, if it does exist or not, we are better safe than sorry right?

if you can explain why climate change is bad in a couple of sentences.

Answer 3

There is a confusion in some minds about the contribution of the sun to global warming. Whilst it is true that the sun is the source of almost all heat arriving at the surface of the earth, this is not the same thing as global warming in this context.

Variations in solar output do not account for the increase in mean global temperatures over the last century. If they did, the earth would be warmest when closest to the sun, and coolest when farthest away; but the earth is closer to the sun in winter and farther away in summer. The issue here is not that heat arrives from the sun (though of course it does), but rather that greenhouse gases act a bit like an inefficient one-way valve, keeping in heat that would otherwise radiate away again. The more greenhouse gases there are, the more of the solar influx is retained, and the warmer the atmosphere becomes. The solubility of carbon dioxide in water is related to the water temperature; as the oceans warm, they release more of their dissolved carbon dioxide into the atmosphere, adding to the greenhouse gas concentrations in the atmosphere, in turn causing still more atmospheric warming.

Answer 4

I quite agree with you. Throughout history, the temperature of the planet has chopped and changed due to natural circumstances, so why are we 'saving' the planet? Saving it from what? A change of climate. It's not a bad thing, but people are SCARED, so they say it is. And if it floods? We should spend less time 'saving the planet' and more time preparing to adapt! We'll ADAPT to the high temperatures. If we just prepare, instead of trying to prevent it, it will hardly be a problem!! I'm so happy to find someone with the same view as me!

Answer 5

If global warming was for real, Gordon Brown would cut the £200 heating allowance for pensioners. OMG ! Now Ive given him something to think about !

Answer 6

If the earth doesn't warm up too quickly then it doesn't seem like a big deal. The 0.1 degrees per decade that we've experienced in the past doesn't seem that serious.

Answer 7

i am not sure anymore. saw this documentary. they said it depends more on the solar acitivity (solar burst etc), then on CO2. The graphs they should on that relationship, did really impress me.
But on the other hand i like what the whole discussion makes with the economy. More renewable energy companies, which cant be that bad.

Answer 8

This is possible in the future if we don't act now, to cut down on Greenhouse emissions. Its also bad to go outside in the sun for long, because of extra UV radiation coming through the hole in the Ozone layer.
If you want to learn more watch the movie by Algore the Inconvenient Truth, its great and factual.
If not satisfied look here: earthguide.ucsd.edu/earthguide/diagrams/greenhouse/ or en.wikipedia.org/wiki/Greenhouse_effect
Good Luck!

Answer 9

No. The Earth's climate can never be static. It will either be warming or cooling at any one time.

Currently the Earth is warming, and the source for all warming on the planet is the Sun.

Answer 10

i just did this speech in my class and everyone agreed on it so i dont think global warming is any good:
People have been putting more and more greenhouse gases into the atmosphere, especially in the past hundred years. Many scientists believe this increase in greenhouse gases will slowly cause the earth to become warmer. This is called global warming. Many scientists also believe that global warming could cause the polar ice caps to melt. This may cause flooding of low-lying coastal lands. A rise in temperature could be enough to endanger the crops we need for food. It could also dry up the lakes and rivers in some areas that provide water to crops, towns and cities.
Many scientists believe that deforestation is causing the earth to become warmer. This is because of what is called the greenhouse effect. The greenhouse effect works like this: The sun's rays pass down through the atmosphere and warm the surface of the earth. The surface throws some of the heat back toward space. However, much of that heat does not escape into space. Gases in the atmosphere called greenhouse gases trap it. This happens the same way a glass garden greenhouse traps heat to grow plants in the winter. The main greenhouse gases are carbon dioxide, methane, nitrous oxide and chlorofluorocarbons.
Deforestation is a major cause of carbon dioxide being released into the atmosphere. Trees and other plants in the forests absorb carbon dioxide to make food. As forests are destroyed, fewer trees are available to absorb carbon dioxide. Also, people often burn the trees when clearing land. This burning releases large quantities of carbon dioxide into the atmosphere. For the same reasons, the cutting and burning of wood for curing tobacco adds to the greenhouse effect.
The smoke from cigarettes also contains greenhouse gases. Cigarette smoke contains carbon dioxide and methane. Smoking worldwide releases about 2.6 billion kilograms of carbon dioxide in the air every year. It also releases about 5.2 billion kilograms of methane every year. Tobacco growing, curing, and smoking all add to the greenhouse effect and global warming.
Scientists have concluded that human activities are contributing to global warming by adding large amounts of heat-trapping gases to the atmosphere. If we don’t act now to cut the pollution causing global warming, we probably won’t like the results. Our fossil fuel use is the main source of these gases. Every time we drive a car, use electricity from coal-fired power plants, or heat our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the air which increases concentration of greenhouse gases in the Earth’s atmosphere, warming the planet and disrupting our climate.
