global warming?

Question

researches have said in 30 years, global warming is supppose to be a big threat, what threat is that? the ice cap melted? hotter summers in 100's? someone be more specific that if global warming continues, what will happen? and if we do something to control it, can the process be reversed?

Answer 1

Coastal flooding, serious damage to agriculture and some animal species. Many more details in the references below.

At this point our focus needs to be on just slowing it down so we can cope. Reversing it will take a very long time.

I can't believe people are still recommending that "swindle" movie. It's scientifically wrong.

The director made a similarly silly movie in 1997, which compared environmentalists to Nazis. Channel 4 had to issue a public apology for that one.

"Against Nature argues that greens in First World countries are responsible for the deprivation and death of millions of children in the Third World. In their callous disregard for human welfare and their fetishism of nature, greens, it maintains, are not merely conservative, but fascist, drawing their inspiration from precisely the same ideologies as the Nazis. It would be laughable, had it not been given three hours of prime time TV."

This one is similar in quality.

" A Channel 4 documentary claimed that climate change was a conspiratorial lie. But an analysis of the evidence it used shows the film was riddled with distortions and errors."

http://news.independent.co.uk/environment/climate_change/article2355956.ece

Even Channel 4 doesn't believe that nonsense is correct. If you go to their website, on the page for the film are links to factual global warming sites. You can "Ask an Expert" and your question goes to a respected mainstream scientist who says man is mostly responsible for global warming.

Answer 2

temperature paterns are a cylical part of the earth just think about the ice age we are tought about that happened thousands of years ago. Glaciers covered north america as far south as florida. So what dou you suppose cause these glaciers to melt? I would not guess automobiles and urbanization caused these glaciers to melt thousands of years ago. When dinosours roamed earth it was supposedly warm everywhere. I feel that man made global warming is one of those the earth is flat type theories alot of people jump on the bandwagon and feel they are right even though they are wrong

Second people are using wheather patterns to state that global warming is happening .you can make statistics say what ever you want take for instance ill prove global freezing. In MN three summers ago we had a very cool rainy summer where temperatures where well below average by over 10 degrees, this february subzero temperatures spanned through out the majority of feburaury (again colder than average) and it is now april and it has been in the 20s (again below average) am I seeing a pattern here or what. We have only been recording wheather patterns for about one hundred years out of the 100s of millions of years old this earth is. So that would also be like going outside today in MN about 30 degrees and stating that year round temps in MN are 30 you would just have to little info to know the true wheather patterns

I think that people are worried about global warming because of the harmful effect that it could have on mankind and its coastal cities.Man kind always likes to have control and always feel they have control and the fact is that mother nature has control we can not control it.

Answer 3

Al Gores movie is mostly is a religious movement and it is an ideological movement and it is pure liberalism. It's oriented toward growing government, raising taxes, and empowering government over the individual, over a long period of time,. In the 13th & 14th centuries. the earth's temp was raised (by natural earth cycles) by global warming and there wasn't even any industrial contributors, Hmmmm. The climate was changed but not enough tp destroy mankind as Mr. Gore would have everyone believe. It actually made normally colder climates into areas of growth and prosperity. England actually became a fertile area for wine vinyards. Water flowed and food grew and people were drawn to areas that were very much less fruitful otherwise. People will adapt!! People always do!! Is the climate changing?.... Yes!, are people to blame?... No!, Can we change it?...No! will we adapt?...Yes. Al Gore says we have 10 years left to save the planet from scortching. When that date has come and gone, then we'll see how much support he has!! global warming has nothing to do with science. Global warming is liberal ideology. Global warming is liberal religion.
Be open minded and think for yourselves.

Answer 4

If the IPCC claims are to be believed, which is doubtful, all sorts of bad things could happen to the planet. Many of those things don't make much logical sense for a number of good scientific reasons. In any case, the mass of the earth is huge. If climate change is caused by man's activities it will be a few hundred years before anything we do today can make any difference.

Don't believe the panic mongers who say the earth will be flooded or heat up like Venus. Neither is going to happen, no matter what.

The more likely scenario is that climate change is a natural event like has occurred so many times in the past. The environment and ecology will adapt to the normal changes in the climate. Mankind may be inconvenienced but that isn't to big a problem. Most likely there will actually be more arable land and faster, more luxuriant plant growth due to the higher CO2 levels and more free moisture.

Answer 5

First - you can't control global warming. It is part of a cycle the earth goes through. Having said that, many scientists believe that "this time" it will be worse than it has in the past because of mankind's contributions (ie increase in greenhouse gases etc.)

Second - Global warming is an average increase in the temperature worldwide. This means that in some places the temperatures will be higher than normal and in others, it can be lower than normal.

Third - it is possible that the ice caps will melt, though not completely. If the ice caps do melt, the water that is released into the ocean will still be very cold. This water will cool the earth and we will be sent into another ice age.

Answer 6

We will solve GW. I sent this letter to 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 7

WOLF! WOLF! WOLF!!!

Don't believe everything you hear, especially if it comes out of the mouth of a politician. People worry about the ozone hole, but then they put 'pollution controls' on the biggest ozone producers we make - cars and trucks. CFC's cannot have caused any problems, because those molecules are heavier than air. So how do they get UP there??? You can't have it both ways. Either CFC's don't get up there, or ozone from auto exhaust DOES. Let's have a little less panic and a LOT more thinking, okay?

Answer 8

Global warming is a very complex collection of many effects

this text only covers some aspects of global warming mainly man made desertification

industrial contamination ,the contaminating effects of the cities ,is another story

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

in North Africa,India,Mexico ,millions of people are effected by land loss and desertification and some have died as a result

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 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 very few desserts.

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

each degree rise in temperature means 10%crop loss

and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
and there are 70 million more peole every year that have to eat and drink and wash

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.



http://www.greenpeace.org/international/...

http://news.bbc.co.uk/2/hi/science/natur...



if forrest are being exchanged for ashalt,concrete and desserts
what is gonna keep this planet habitable for us

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.

and improve economis situations for people who live in areas where deforestation has become their only alternative for survival ,which is a short term solution that has long term negative effects

try to replace farming with eco tourism,

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

here are a 100 more ways

Answer 9

I would recommend seeing Al Gore's documentary An Inconvenient Truth. We are reaching the point of no return. Thousands of species are expected to become extinct. Diseases run rampant in hotter temperatures. We are running out of resources, and that will inevitably cause war as people are fighting for resources.

Answer 10

FUTURE CHANGES
These are based on predictions, they aren't guaranteed to happen, they may not be as bad as predicted, they may be worse. Much depends on what we do in the future.

> Temperature rises of between 1.8°C and 4.0° by the end of the century
> One person dying from the effects of GW every 90 seconds in 20 years.
> Millions of square km of agricultural land lost, millions of square km of new land gained.
> A quarter of species of plants and animals extincy by 2050 including polar bear, grizzly bear, penguin, turtle, caribou, walrus, plankton, krill, whale, crab and seal
> Increase in frequency and intensity of hurricanes, tornadoes, cyclones and the like
> A nine fold increase in flooding
> Many lifes lost through heat related conditions, some saved as a result of less cold related conditions.
> Increase in droughts and famines
> Insect infestation leading to spread of disease
> A shift in seasons
> Some areas drier, others wetter
> Rising sea levels fforcing evacualtion from low lying communities.
> Other effects: Arctic warming, increased power outages, marine food chain disruption, changes to bird migration patterns, more wildfires, erosion, desertification, disappearing beaches, damage to tundra regions, impact on ozone layer, insect infestation, threat to boreal forests, coastal erosion, threat to mountain environments, loss of wetland and marshland habitats, decline in bird population, thawing of permafrost, increased acidity of oceans, release of further greenhouse gases, increased allergens (asthma etc), coral destruction and bleaching, loss of ocean conveyor belts (Gulf Stream) etc, loss of Arctic sea ice, impact on winter sports.

CAN WE CONTROL IT?
Control is different to reducing the effects of, many steps can be taken to reduce the effects http://profend.com/global-warming/pages/combat.html#1 controling involves something called geoengineering - changing the climate. Several schemes are being looked at...

> Human Volcano - Firing sulphur into the atmosphere to reflect back some sunlight
> Sulphur Blanket - Releasing sulphur dioxide from rockets to block out some sunlight
> Solar Mirrors - huge mirrors in space to reflect sunlight
> Global Sunshade - Trillions of glass disks in space to divert the suns rays away from earth
> Moving the planet - Moving earth 1.5 km further from the sun
> Cloud Seeding - making artificial clouds to block out sunlight over the oceans
> Carbon Scrubbers - Artificial 'trees' that use a chemical process to remove CO2 from the atmpsphere
> Phytoplankton - Increase the number of these tiny marine plants that absorb CO2

All 8 schemes are designed to prevent things getting worse, the last 2 can also reverse the trend if implemented on a large enough scale.
