According to CNN, a group of European scientists warned that a long-term increase of 3.5 degrees in global temperatures could wreak havoc in the world. This change is brought about by the constant emission of greenhouse gasses by the major industrialist nations like U.S, number one on the list, and China which is only behind the U.S in wrecking the environment.
What can we, the people, do to stop (or at least curb) such indiscretion???
We, as small individuals, cannot do much I don't think. To save the world, we must change the way we create things, e.g. manufacturing. even though car fumes are a big problem, factories are the worst.
I read a doomsday article somewhere that said something like even if we stopped greenhouse gasses today it would still be to late to alter the course we are on for about 11 years.
My advice; buy land about 100 miles inland, build a beachhouse for your children to enjoy.
Nature always took care of itself.
The increasing global population increases demand for food and industrial products.
To meet those demands an increase in burning calories through direct consumption and burning fossil fuel for driving the machines increase the global temperature.
Ice will melt, oceans will rise.
Climatic disasters will set back the number of humans who have demanded the food and the industrial products.
An economic disaster must follow.
Factories must close.
Fuel consumption decreases.
The temperature drops.
The ice builds up once more.
Nature is the winner.
We lose. _________________ Hemetis
Well there are so many reasons why we should look into the environmental problems!!
It is the result of human activities that
· Since the beginning of the 20th century, Earth's mean surface temperature has increased by about 1.1°F (0.6°C).
· Warming in the 20th century is greater than at any time during the past 400 to 600 years.
· Seven of the 10 warmest years in the 20th century occurred in the 1990s. In fact, the hottest year since reliable instrumental temperature measurements began was 1998, when global temperatures spiked due to one of the strongest El Niños on record.
If you doubt whether our planet can explode or not…probably the following data can convince you of what I am talking about here!!
· Mountain glaciers the world over are receding.
· The Arctic ice pack has lost about 40 percent of its thickness over the past four decades. Key Antarctic glaciers (Hektoria, Green and Evans for example) increased their melting rate 8 times in 3 years (between 2000 and 2003.
· Volcanoes become active under Arctic Ocean and in Antarctica. The Largest Volcanoes on Earth are losing their snow-caps.
· Global sea level is rising about three times faster over the past 100 years compared with the previous 3,000 years.
· A growing number of studies show plants and animals changing their range and behavior in response to shifts in climate.
· The weather around the globe becomes more violent every month
· In February 2005 NASA officially admitted in their public statement that Earth absorbs more energy from the Sun that it is able to reflect to space at night - at least 0.5W/m2 more. Pollution increases daily and Solar activity is on the increase until 2012. Global increase in tectonic and seismic activity seems certain.
Have we reached the point of no return?
The question to “why this is happening??” probably doesn’t need to be answered!!
Problems like increasing pollution, deforestation, etc are known to everyone!!
Well if we try to rank the different countries in accordance to their contribution in the emission of heat-trapping gases to the atmosphere, we might get much-expected chart, with USA leading the world, followed by Australia and Saudi Arabia. In general, developed countries lead in total carbon emissions and carbon emissions per capita, while developing countries lead in the growth rate of carbon emissions.
Stating the solution to the problem will be again be like repeating nursery rhymes..there is nothing much unfamiliar, else than the contribution of the people!!
The Nuclear Option...
This is relatively a new method that has been researched over from past so many years. The only reason why this seems to be attractive to the scientist is that it will help to reduce the consumption of fossil fuels, and thus CO2 build up in the atmosphere.
The conversion to a hydrogen fuel cell propulsion system to replace the petrol/diesel engine requires massive electrical energy input to separate the hydrogen from water, and the only adequate and presently available option is nuclear fission.
Wind and water-power are just not credible options for the power generation necessary for massive conversion to a hydrogen fuel cell propulsion economy.
Superconductivity
There is also an urgent need to fund massive research into the development of superconductors, which will operate at normal ambient temperatures. Such materials will potentially allow the low loss transmission of electric power over long distance with cables of relatively lesser diameter than conventional copper.
In the past I have listned to radio talk show host Michael Savage. He likes to note that the Earth goes in and out of ice ages quite frequently; that it is natural for the Earth to change temperatures.
Obviously we are accelerating at least one side of the process.
1. Future options imply IGNORING pollution until 2050 has little effect on the 2100 situation - - or even Negative, if money comes from Research.
Reason is the Industrializing 3rd World REALLY can put out the Pollution at 20 times our rate, so idea is to have AND ACTUALLY BUILD, solutions from 2050 - on.
I have run across this SEVERAL times.
Even the National Research Council's Abrupt Climate Change: Inevitable Surprises. (see their proposed actions at the end: as money now has little effect, they reccommend "no regrets" changes, i.e. measures that run a profit or nearly so).
2. Getting DEAD in the meantime, oddly, is MOST likely from such a source, i.e., we may trigger an ICE AGE.
Gradual Warming is a SMALL PROBLEM.
SUDDEN SHIFTS are not, and all evidence is that small changes past some TRIGGER POINT unlease 'minor extinction' Events.
Ironically: use the same book as your source for that (though beware, Professors at Universities delight in changing "10 years or less" into 'we know it takes 10 years' then the next makes it AT LEAST 10 years.
The reason the "Day After Tomorrow " movie had a 1-month timespan - - is because of the Acidity meter for the Ice Cap cores at the last transition - - the meter, sampling at just over 15 times a year (samples were sent off to other analysts, who generally got an ice chunk for 1 year in each 10, thuis the frequent 10 year time span) - - well, the Ice had had high dust levels, thus a high-pitched sound (8 for fine dust, to 20 times, present levels). The Ice specialists gathered one day all eager for the transitional centuries. Most of the day they just heard:
wee, wee, wee, wee, wee ... then: (Source: the book CLIMATE CRASH):
wee, BOING ! WEEP ! WOOOP!, woo, woo, woo .... (fro 1000 years, then the sound gets deeper)
OK, the "p" must be pegging the meter: Weep is up WOOP is down.
. . . I don't think we would like living through BOING !!!!
. . . if we could - - live, that is (please note the movie overdid the Ice, but only after setting up the WINDS - - then they forget about them, because the WIND leaves NO above-ground survivors. No rescue, no movie Hero. The Cold was survivable. 400 mph winds are not, and NO building stands. Snow, however, implies there was some warning as the years changed in a group of 3 years , about 2, 12, and 1 degree, (F). Most of the change in 1 degree (cf Alley's book: The Two-Mile Time Machine). Note Alley was AFRAID to write the above in his own book, only very reluctantly puts out the "mostly in one year" info, and when he was published in Scientific American they either changed 1 to 10 or he chickened out.
Myself, I DO say the lack of ANY model that recreates even the every-few centuries smaller LURCHES of climate in the Chaotic Ice Age, means even the NRC's consensus we WILL trigger SOME event - - may be wrong.
What it is, is: DANGEROUS.
You can take your Upper, and LOWER limits, and forget them.
I have suggested, with, to combat
This
The Chemical threat to Water supplies
Biological Threats requiring Mass-Quarantine
. . that at least 3-to-10 percent of homes get a 3-month or more water supply with
a ground-water pump or
large buried Pool (thermal mass heat pump)
. . . either, using the 65-degree year-round deep ground temperatures for VASTLY more efficient home heat & cooling - - and allowing every neighborhood a basement refuge. Shades of Fallout shelters.
Wow, I couldn't quite follow samo on that last post, but I have a feeling at least most of it was correct.
I haven't read too much in the way of a differing opinion though, so I thought I'd offer one.
While I believe that man is slowly ruining the earth, I also know for a fact that we cannot attribute the current climate change to man alone. Scientists know that the earth goes through regular cycles of warm and cold. It is a harmonic vibration if you will.
Small vibrations vary the temperature on a yearly, (or if you look at the data even weekly) basis (no I'm not talking about the seasons, I'm talking global temperature measurements.) Large vibrations on the timeline, show evidence that temperatures vary over decades as well, and we all know that Ice Ages have occured, meaning the temperature varies also on the large scale say over 1000s of years.
Traceable human history says the last major global change took place a couple of thousand years ago. We have been keeping moderately accurate weather data for just over 100 years.
Some scientists are trying to use giant sequoias as weather records, but they only serve as records for the area they live in. If we could find similar data for every major region of the world (using the ice sampling at the poles) then we might be able to construct a semblance of a weather pattern over say the last 300 years at best. We simply don't have the data to support any scientist who says that we will have a major crisis in the next 50 years.
That said, we do have empirical data saying that what we are doing to the environment could cause and increase in temperature globally. There may seem to be correlative data between that and the increasingly hot el nino patterns, but simply put we can not say that the former causes the latter.
Hopefully within the next 5 years all the middle and upper class people will buy more than 60% hybrid vehicles, people who live in an urban/suburban area will learn it is greatly cheaper and easier to use mass transit, and mass transit will switch over to hydrogen fuel cell technology (since it is easier and cheaper to run a bus on a fuel cell than a car.)
One more thing, it takes as much or less energy to create the hydrogen and oxygen as is wasted and consumed in the pumping and refining process of petro-chemicals.
Actually if it comes to that, then Canada is the wrong way to be heading. The one thing environmental scientists have learned is that if we don't stop it now, we will be heading for another ice age. Therefore, Canada would be the last place you would want to be, unless you want your body to be preserved for future scientists to find it.
I myself, don't believe that we will be around long enough for that to happen. Having faith in God and the prophecy of the Bible, I believe that the earth will not be ruined to that extent. Some will survive the Great Day of God.
A Washington Post Article notes that 2005 will probably have the highest mean global temperature of any year since the advent of systematic temperature records. At the moment, the mean temperature is about 0.75 degrees C above the global mean from 1950 to 1990, approximately .04 degrees higher than 1998, the year of the previous record. Only something dramatic, such as a major volcanic eruption, could cause enough cooling to miss setting a new record.
However and if they are "friends of science", they maybe should read some current papers - and maybe not quote old ones out of context. As far as "Myth 1" is concerned, it is true that there has been (and to a small degree still is) a discrepancy between surface temperature and climate models on the one side, and balloon and satellite data on the other hand. However, recent publications have very nearly closed that gap. It turned out that the satellite data suffered from undetected orbital drift (i.e. the satellites reported night time temperatures as day time temperatures) and the balloons suffer from a number of sensor and calibration problems. If the data is corrected for these errors, there is a rather good fit with current climate models.
"Myth 4" is another mixture of truth and falsehood. Yes, water vapour is a greenhouse gas. However, relative humidity is more or less a constant in the atmosphere. Thus, the amount of water vapour (absolute humidity) is driven by the temperature. In this way water vapour increases the effect of any other heating - its an amplifier, but not a cause of global warming.
If you look over the site, you find more gems. "Myth 6", for example, not-cites the 1996 IPCC report, totally ignoring the current (2001) and upcoming reports.
According to CNN, a group of European scientists warned that a long-term increase of 3.5 degrees in global temperatures could wreak havoc in the world. This change is brought about by the constant emission of greenhouse gasses by the major industrialist nations like U.S, number one on the list, and China which is only behind the U.S in wrecking the environment.
What can we, the people, do to stop (or at least curb) such indiscretion???
gobal warimg can be slowed downed but it cannot be eliminated.
For those of you concerned with ecology and the future of our planet, I strongly recommend reading Bjorn Lomborg's The Skeptical Environmentalist. Through a lot of well documented facts, Bjorn argues that things are really not that bad as they tend to say us. An interesting reading with plenty of scientifical data, and with an alternative approach.
