Global Warming

krismister06 asked:


It seems all you hear during the HOT summer months are stories about “global warming” but when winter starts to cool things down, those stories are few far and in between. Why?

When it comes to protecting our planet, there is no subject that is more important then that of the main cause of global warming. Although there is still a lot of work and research to be done in the science community it is important to know that a lot of people feel that the main cause of global warming is people. What we, the human race that depends on the planet, are doing to the planet is truly upsetting. Our actions and the chemicals that we use on a daily basis is said to be a big factor in everything warming up.

Unlike a natural cause of global warming, we are able to control ourselves in enough of a way that could potentially protect our planet from being hurt any further. The main cause of global warming is certainly something that we should all be ashamed of and therefore doing as much as possible to make sure that this is not the case for the future generations. We have to educate ourselves and then educate our children so that the situation does not continue to get worse over time.

Teaching Our Young People

By taking a few extra moments out of your week you could truly impact the way your child understands the main cause of global warming. If you start asking questions you may be surprised to find that they may not even truly understand what global warming even means. As shocking as that may be it is time to start looking towards the future and make sure that our young people know as much as possible in order to make the right decisions as they age in order to protect our planet, to protect their futures and the futures of their children.

If your school is not activity talking about global warming then that may be something that you would want to discuss with the teacher or the principal. There is no reason why there could not be small lessons every once in a while in order to truly teach the children about the main cause of global warming. In the end, even if just a few children are really reached with the message about the major problems with global warming then it was all worth it. Take your time and dedicated yourself to making sure that our young people know what they need to know in order to help the situation.

Is global warming real? Is something happening to the earth’s ozone layer?

There is no doubt the average ambient temperature is on the rise and has been for some time. In fact long before it became popular to believe so.

Global warming has been a fact since the ice age! The ozone layer is also undergoing change as well. Factor in category level hurricanes, typhoons, changing weather patterns and seismic activity all on the rise…what’s happening?

Is there any simple explanation? Is there possibly more to it all than the standard catch all “greenhouse gases” at play?

Possibly just a tad more complex then air pollution and deforestation.

The facts point to massive earth changes that caused the earth to evolve from its previous state of Eden as described in the Book of Genesis.

We pump our oil from beneath the frozen tundra’s of Alaska and Russia; from beneath the dessert sands of the Middle East; and the ocean floor provides the rest. These regions were at one time lush green gardens full of plant and animal life. What transformed them all to wasteland?

Was it green house gases, air pollution or was the dinosaur to blame by over harvesting and poor environmental policies?

The question then stands, have the climate and environmental changes that we are now seeing happened before?

It seems like I’m having to explain the difference between weather and climate or short-term and long-term in half of my answers these days.

What percentage of man-made global warming doubter questions fail to distinguish between weather and climate?

If someone does a random sampling to give a concrete percentage, that will merit best answer.
Dawei - well said. “Believers do it to”, even if it were true, does not excuse this basic error. And the scientific experts do not make it.

Still looking for a figure to answer my question though.

While the drastic effects of global warming has been discussed in many scientific circles, had their run on TV and even had major exposure through well-meaning (but sadly inaccurate) Hollywood films, it’s a concern that has a broad political, economic, social and geographical significance to countries all over the world. Quite literally, for all of us, there is nowhere to hide, nowhere to run and we can’t stop the climate from changing. It’s just way too big for us.

How to recognize global warming

Whether or not it’s brewing something good or something bad, Nature always tries to warn us through many signs. The slow process involved in global warming results in many different things and some of its signs include:

Melting of glaciers

Most of the mountain glaciers on our planet that have been monitored for the past 150 years are reportedly shrinking. The glaciers most affected by global warming those located in the lower latitudes and many of them are disappearing. If glaciers continue to shrink, it could affect water supply in areas that depend heavily upon mountain watersheds.

If the scenarios of global warming continue, most of the glaciers that still stand today will disappear by 2100.

Ocean warming

Sea level increase is attributed to warmer temperatures, which in turn result to the melting of ice glaciers. Over the last 100 years, sea level has increased from 10 cm to 25 cm. Projections over the next hundred years indicate that sea level will rise higher, from about 15 cm to 90 cm. Based on the higher figure, that’s about 3 feet.

Translated, this could mean that beaches lose about 50 feet of area for every foot of increase in sea level. Some islands may even disappear beneath sea water completely.

Heat waves

Heat waves and periods of weather that are unusually warm are also signs of global warming. These may come about with varying degrees of their severity and frequency, causing concerns in the economics and health on a global scale.

How global warming brings climate change and what it means to us

The earth’s climate has always been changing, although not at an abrupt rate. There had been periods of warming and cooling in the earth’s 4.65 billion-year history. Strange as it may sound to some, this is the reason why life became possible on this planet millions of years ago. Unfortunately, not all of the changes in climate brought about by global warming may be beneficial to many of us.

For one, global warming will raise the temperatures in some regions of the Northern Hemisphere, causing the melting of mountain glaciers. This means that areas that are currently experiencing light snow may no longer experience snowfall anymore. Snowlines found in mountains in temperate regions may also be higher and packs of snow will melt earlier than before.

Spring may be experienced earlier and temperatures during night time and in winter will rise. The world will experience a more humid atmosphere since sea water will have a higher rate of evaporation. With greater humidity, rainfall is expected to increase on average.

Storms will also occur with more frequency and intensity. Ironically, water in the soil will evaporate faster, causing dryness between rains. Regions that are already considered dry will experience more dryness. Some semi-arid regions in the African continent, for example, may suffer more while areas that depend on their region’s mountain snow packs for irrigation will not benefit from earlier melting between growing seasons.

With warmer weather, some hurricanes will be more severe and winds are expected to blow stronger. It is also possible that wind patterns may shift. Extremely cold periods may be experienced as well.

The phenomenon known as El Nino may occur in more frequency and severity. This is expected to affect different regions in many countries. All in all, scientists will have some difficulty in predicting weather patterns.

With changes in climate brought about by global warming, health concerns and risks may also increase. Heat stress and diseases may become common in places that did not have any problems with them before.

Global warming is an issue that requires immediate action. Even plants and animal species are adversely affected by it. While many of the changes that occur in our planet are totally out of our hands, we have been direct contributors to events that have had negative effects on our environment. This is why many leading social and scientific organizations have urged nations to cooperate in the move to counter this worldwide problem before it’s too late.

About Global Warming

Nowadays, global warming are becoming heavier and heavier, many people are the victims of this environmental problem. It is the fact that global warming is going to lead to a rise in human-beings’ sickness and death. According to a report, owing to the climbing average temperatures, there are at least 20,000 Europeans in August in 2003.It’s an astonishing number for every person so that we should do some actions to solve this problem.

I think there are several key affected by global warming as follows:

AIR we are used to thinking of industrial and traffic pollution as having a detrimental effect on air quality.

WATER and INSECTS are also the problems of which can affect global warming.

Don’t deny it anymore; we need to stop global warming!

Don’t deny that we are causing global warming; we need to stop global warming before it is too late. America and other governments do not want to admit they are the cause because they do not want to pay to fix the problem. They are hoping Nature will fix the problem and it will all go away or they hope that our children or grandchildren can solve the problem. We need to incorporate that famous statement “The buck stops here” and fix the problem.

Facts to be accepted On Global Warming

Global warming is a realistic threat to the very existence of life on earth. The unprecedented rise in earth’s average temperature is a cause for worry. Moreover, the rise in temperature is projected to continue in the same rate, if some urgent steps are not taken immediately. Global warming has already affected the pattern of climate in many places. Many of the recent floods, hurricanes and tsunamis are known to be a direct result of this phenomenon. Global warming is also contributing to the gradual rise in sea level in many places around the world. A collective effort on the part of all us is what is needed to stop global warming.

Can Global Warming Usher in the New Ice Age?

It’s quite possible that global warming may cause the new Ice Age. This paradox can be explained briefly in that the Gulf Stream current and the North Atlantic Drift (both are major warm-water currents in the northern hemisphere in the Atlantic Ocean) heat up the air around them which in turn prevents the temperature from dipping precipitously. However, with the currents being salt-based and with the rising temperatures causing massive ice melts, the onslaught of fresh water will dilute the salt therefore eliminating the warming effect of the two currents. Once these currents are shut down, the temperature will drop precariously in the northern hemisphere thus possibly ushering in another Ice Age.

Global warming is the issue worrying one and all environmentalists around the world. It is now becoming quite imperative that be stop global warming fastest so that the effects of warming that have affected earth adversely are reversed and we are able to live a little happily than before.

There are many things that can be done on a personal level to stop global warming. Firstly, we should know how much heat and pollution is created by every family, this pollution is producing green houses gases and accelerating the process of global warming. One of the answers to stop the warming is that we should consciously start planting trees not just around us, we also ensure that the lost rainforests and tropical forests are restored back to their normal volume.

These tropical and rain forests work as lungs for the entire world, creating oxygen and purifying the air. Therefore, when these are cut off, it can harm the entire ecological system of the Earth, this means there will be very less oxygen and lesser trees to provide us with oxygen. It will make us susceptible to many breathing disorders and other health problems.

We need to stop global warming, is that the scientists have been telling us for quite sometime now. The reason is obvious, if not stopped or reduced, the large snow mountains at the poles will start melting, and this will lead to a sort of catastrophe. World’s major population stays at the sea side. Once the ice starts melting it will increase the sea levels several feet above what it is now. It has been already reported from the countries near the North pole that the rising sea levels has caused them to relocate their homes a little farther.

Rising sea levels will mean destruction of huge numbers of human beings, animals, property, industries, flora and fauna. This will also mean flooding and increase in salinity of available ground water. This again is potentially harmful for human health. This will also mean millions of people will have to move from near the sea to interiors. This would also mean loss of life and loss of millions of dollars.

If you feel strongly against global warming you should try and make contributions to organization you feel has been working actively for the purpose to stop global warming. Your small financial contributions can make a lot of difference. Your contributions can provide boost to these organizations to find man power and monetary power to buy land and convert it from arid dry deforested land to a good sized forest.

You can also stop global warming at your personal level. You can try and plant as many trees around your home. You can also try and use minimum electricity, you can try and avoid usage of sprays, non-green products which increase toxic waste on the Planet. It is necessary to stop global warming so our children can live healthy and long lives.

Flinter asked:


Throughout the history of the Earth, there have been catastrophic events. Will global warming cause a bigger problem than the warming that ended the Ice Ages or the event that ended the Age of the Dinosaurs?

Nickolas

It’s me asked:


I believe in human caused global warming, but it’s a consensus in the non-politically motivated community that interglacial periods last about 10,000-15,000 years. And the last glacial periods ended that long ago.

So could global warming forestall this human catastrophe?

Frankly, I think it doesn’t matter either way because we’re doomed to extinction sometime soon. Most Earth scientists agree on this too.
