Global Warming?

Question

I need a good website which talks about the impact of human activities on global warming, thank you.

Answer 1

I'm not sure about what your educational level is or how much technical detail you want, so I'm going to throw a wide variety at you. The broad consensus among climate scientists is that climate change is occurring and much of it is probably due to human activity. All the scientific bodies that deal directly with this issue are in agreement on this. There are some alternate theories, but they are very much in the minority.

Of course, important questions remain. How much of an effect is due to greenhouse gasses and how much stronger will it get? What will the environmental, physical, and economic consequences be? What can we do to fight this? How much will it cost?

Hope this helps.

P.S. It is my understanding that the aerosols we cut back on actually reduced the effect of the greenhouse gasses and in working to save the ozone we exacerbated the warming problem. Climatology is a very, very complex science.

Answer 2

Here is an answer I gave too another Q. The polar ice caps are melting because UV rays cut and crack the ice which causes its denigration. The high UV is a result of CFC's-and most are global warming gases. Here is a letter I sent Al Gore: Putting the technology together to start cleaning up and reintroducing new ozone to the atmosphere is possible. The cost and size of this project means taking a long term commitment. I am proposing the biggest cleanup in history. Al, I do not see any proposal that is realistic or proven at any cost, not even Washington can solve this problem. But if every person on earth does his or her share, we may be ok. Never-the-less, I see governments acting like a deer in a car’s headlights and people doing the same thing. The inevitable is almost upon us. Cleanup and change is the only option.
The first cleanup machine starts with a ten billion dollars investment. Ten year later with twenty-five machines operating, these machines will produce enough ozone to replace both holes at the poles. But more importantly, these machines will remove chemicals that deplete the ozone. Beyond making ozone, decreasing the poisons that deplete ozone, these machines reduce the major greenhouse gases and unbelievably we can have all this for fewer than one hundred billion dollars.
Beyond cleaning up our atmospheric mess as I am suggesting, we humans must do a better job reducing or cleaning up carbon monoxide, collecting and storing methane and ethane for fuel, burning less of everything, cleaning up our forests and using more solar insolation. Solar steam electric generators are the type of systems we need and are 90 percent efficient and near 100 percent if heat recovery is used. I believe nearly 30,000 MW are needed in the USA and Mexico over the next 30 years. This opens the door to new electric cars, new construction vital to our way of life, new bullet trains, and these industries produce new high paying jobs. From small scale solar generators on malls, to 2000 acre collector sights, these systems are viable and ready for production. The Federal Government must give up some land, money and have less regulation to help save the planet from disaster.
Al, spreading the message that we can help ourselves is a key to the development of these businesses. Washington can help: the businesses need grants, patents, land and regulations. Congress must create a pollution surcharge. From gas, coal, diesel, wood to cooling towers, from cattle, other ranches to cigarettes, from agriculture burning to airplane passengers, this surcharge can fund parts of these projects and many stationary pollution control devices in general.
Your personal support is very important to getting the atmosphere cleanup started and developing sights for solar generators.

Sincerely,

Answer 3

Glaciation and interglaciation (warming cycles) are geologic processes in play in our planet's history long before life existed, let alone humans. Humans cannot affect geologic processes.

You might find sites on climate change.

dont know any websites
read plan B it is very good

Is global warming a man-made menace?

not all there are natural cycles in the planets life
but a lot is influenced by mans existance ,and this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations as well as destructions of essential componants the ensure living conditions for all life forms

some home truths

politicians and scientists who work for politicians have downplayed the facts because solutions are expensive and means change and change effects many people income,and most of the world is kept in the dark of the real things that are going on.


in North Africa,India,Mexico ,millions of people are effected by land loss and desertification


in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days

in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)

,the Sahara is growing by 7 kilometers a year
and all of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were no desserts.

collectively this planet is drying up because of bad farming practices like,over grazing and fertilizers,

as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss

each degree rise in temperature means 10%crop loss

more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,

and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing

RISING SEAS
The northpole is melting ,and we will know it without ice in our life times.
this does not affect the sea level because it is ice that is already in the water.but the melting ice from Green land and the south pole ,are another matter.

Global warming is in theory reversable,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,

At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where.

SOLUTIONS
if you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes

reduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.

the capture of carbon and the production of water and assist the aquiferous manta.

the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia

Waterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.

the protection of existing forrests.

stop building more highways,urban planning to include vegetation stop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.

education to motivate people to auto sufficiency by building more home food gardens.

education on environmental awareness
education on family planning to curb over´populaion

Agricultural education and improvements to follow the principals or sustainability and soil management.

more environmental or land ,design to prevent bush fires,such as--fire breaks

,more dams.regulations and control for public behaviour

alternative effeciant public transport to discourage the use of the internal conbustion engine

recicling wastes,limit water use
