those who blame mankind for global warming. answer me this?

Question

Recently an ancient lake in darfur in part of what is now the saharah desert was discovered. They say it was roughly the size of lake Erie and that roughly 5,000 years ago there were multiple lakes and rivers in that region and that the landscape was much different including lush vegitation, wildlife as well as human settlements. At another dried up lake they discovered in that same region they found tools and other items belonging to humans living in that area. So what happened? how did a lush area with lots of life and water turn into the Saharah? Were the humans in that area driving suv's and not recycling? And thus whamo global warming and hello Saharah? Or is it that the earth changes regardless. It is what it does. So don't feel guilty that you fly airplanes and smoke cigars. We are not to blame. Light up and enjoy the ride and when the earth decides to remodel don't blame G.W. .

Answer 1

Only 3.5% maximum of carbon dioxide is man made even according to the scientists who support GW. They also acknowledge that the earth has warmed by about half a degree Celsius (one degree Fahrenheit) over the last 100 years. Hardly the 11 degreeC rise that was splashed over recent newspapers.

So, where do these inflated figures come from? Mainly from people who depend on government money to fund their pet projects. Even the Head of the IPCC resigned last year due to the way political interference was used to remove considerable relevant information from reports.

Millions of very well paid politically motivated jobs have been needlessly created to cater for the GW misconception. Even worse, many millions in taxpayers' money is spent on subsidizing activists and political hangers-on to fly around the world to visit communities who are living very well, but have a non-existent, perceived 'challenge'.

Even the BBC has now quietly admitted that global temperatures fluctuate over periods of time and that global warming is a normal state. They even affirm that, 'Throughout the history of the Earth it has been unusual to have one polar ice-cap; it is unique for us now to have two of them.'

Answer 2

No one has ever said that humans were responsible for every climate change that has ever occurred, Great Da... I am surprised you couldn't figure this one out on your own. What scientists are saying is that we *are* responsible for *this* one. I don't really see how your 5000 year old lake in Darfur has anything to do with the current trend, which started a century ago.

Even though there wasn't any industrial pollution to drive the change, there was certainly plenty of carbon dioxide around. And as we all know, CO2 is by far the most import GHG, and is responsible for 9-26% of the total greenhouse effect (the range is due to spectral overlaps with the other gasses), and is responsible for approximately 56% of the warming over the past century.

If you have any objections to the theory, feel free to message with them and I'll try and clear things up for you.

Answer 3

Climate change is going to happen eventually no matter what, how ever we can slow down the process by doing things to help out our planet. Scientists agree the Earth's climate is being directly affected by human activity, and for many people around the world, these changes are having negative effects. Records show that 11 of the last 12 years were among the 12 warmest on record worldwide. Carbon dioxide levels today are nearly 30 percent higher than they were prior to the start of the Industrial Revolution, based on records extending back 650,000 years. Its obvious that polution is not good for the earth so how can you say its not the peoples fault.

Answer 4

We cannot deny global warming - the planet is getting warmer, but this warming is not caused by increases in Carbon dioxide in the atmosphere. We know that in the middle ages the earth was much warmer than it is today, we also know that between 1945 and 1975 global temperatures fell - and there was plenty of industrial activity during that period. Rises in Carbon Dioxide levels follow rises in temperature, not the other way around.

And what of the consequences of global warming - East Anglia submerged under rising seas. Well it didn't happen in the middle ages so why should it happen now. Ice is less dense than water - that is why it floats, so when the floating ice cap melts it simply occupies the space of the ice that was below the surface when it was frozen, it has no net effect in sea levels.

Answer 5

Here is the thing.
The Earth changes constantly. It is proven in history just look at geology.
But science has proven that Man is partly responsible for creating this warming effect to. Man has gluttony. We want the best of everything and we spend vast amounts of money to get what we want (jewelry, suvs, large homes, fashionable clothes, specialty foods). All these things the consumer wants pushes the industry to change and develop more and more stuff .
It is all about Consumerism. We shop until we drop. We buy stuff we dont need and discard what we no longer want. Our lives our build on consumerism.
Does someone who lives in the south really need an SUV? A hummer?
Hummers were made for the military not the general population. But if you buy one and drive it around, you are better than your neighbors right???
This is the mentality of people today. We all want to be better, richer, smarter, and have more.
Our governement does nothing to change this factor but instead it condones it. Why? The tax dollars you spend on merchandise and gas fills the pockets of our government. Why change anything?
Even when it is directly responsible for air polution, water polution, landfills, and the loss of animals and vegitation (trees). Build more and more homes, larger and larger homes, and spread outside the cities and consume all the wildlands. What does it hurt right?
Look at the PHOTOS taken from some of the space trips of our Mother Earth now and compare them to photos taken back in the 60's. They have vastly changed because our planet has changed FOR THE WORST.

We need to take action now, and it is still too late.

Answer 6

Desertification (the process where a region dries out, ie, becomes desert), is a different process to global warming.
Global warming will not necessarily CAUSE desertification everywhere; some places may get wetter.

Whether you dispute the idea that global warming is man-induced or not, what is undisputable is that a) atmospheric CO2 has risen dramatically and b) mean global temperatures are rising.

Answer 7

Every one who thinks they have the answer to this one is wrong. Popular scientic opinion favours human derived global warming but then not so long ago popular scientific opinion favoured bleeding with leeches. There are very good reasons for developing cleaner and more efficient energy but global warming is pretty low on the list. The number one reason to be more energy efficient is too avoid war over oil,gas and other natural resources. If the climate changes we are adaptable and will find a way to cope. If we are at war we are adaptable and will find a way to destroy everything.

Answer 8

Certain variables effect the way a desert moves. Storms, rainfall and wind all effect how the sand is blown or carried. The Sahara, in particular, is a shifting desert and has moved hundreds of miles in its own history. The lakes you speak of would have been changed by this movement. On it's trailing edge, the land is returning to being lush and green. It is irresponsible to assume that we do not have an effect on the environment and you should think before making broad statements.

Answer 9

Well nature has its own cycle, patter and style .. True. But that dosent give us permission to be careless.
Everyone knows that one will die some day or the other But that dosent mean that we become careless and dont take care of ourselves, We have to else we could have an accident or health might suffer and we might also die today instead of years later its upon us to maintain our body and ourself mentally and physically and another example when our house gets damaged , we repair it, right we don't neglect it thinking that ultimately one day we will die or that the house might get destroyed in a tornado/ flood etc Similarly just as our body is the home for our soul, our bulding / flats houses home for our body this Earth is the home for our house and our self too so we do have to take care for it even though we might just survive for 50-60-90 or may be even 175 years but that dosent give us the right to neglect it and let it rot. We have to take care of it. Hope you'll agree that we need to control the G.W.

Answer 10

You know that country next to the sahara with all the pyramids? You may know it as egypt, and over 4000-2000 years ago was quite an advanced civilisation with intensive agriculture. Well they used these lakes and irrigating the Nile to intensively grow wheat, clear felling and basically ruining the top soil. Kinda like in Brazil with what they're doing to the rain forest. The sahara is currently expanding westward and southward at quite a speed, the fastest it has ever been recorded as growing!

There is a similair thing happening in central asia today, caused by intensive agriculture where the rivers feeding the Aral Sea are drying up after being diverted for years to irrigate agriculture.
