Global warming?

Question

My son asked me a question that i can't answer. He wants to know why we call this problem "global warming". If Parts of florida and california that have never seen snow before saw snow this year and temps in the north are colder, why isn't it called global cooling or freezing.

Answer 1

Global warming means that the Earth's average temperature is increasing. Some "symptoms" of global warming are the unusual weather, disrupted rain patterns, and more violent storms.

Answer 2

The theory that the temerature of the global air mass is increasing is not proven. Those who sell the global warming theory can only offer weak, statistical inference as proof. The claimed increase is 0.85 Celcius or 0.3%. The mean temperature was calculated from fixed, ground weather stations. These samples are not random and, therefore, cannot be used to calculate a statisical mean. The error in the mean temperature calculation is much greater than the claimed increase.

Suppose we swallow the bait and assume that the global mean temperature is increasing. Why must global warming be caused by CO2 and not by changes in the earth's orbit or the sun's solar output? The answer is found in human nature.

Taxing people on the premise that science is somehow going to change the earth's orbit would stretch credibility too far. A tax to find ways to change the sun's solar output would be too crazy even for Hollywood. Although, some people would believe it just as some people believe in UFO's. The key is to find the balance point; the lie must be scary enough to hook the public interest but retain enough believability for mass consumption.
CO2-caused global warming is a propaganda campaign by the bureaucrats of the EU who are wetting their pants over the money they will rake in from carbon taxes.

No-one denies that bulldozing a forest and building a sub-division is going to take away wildlife habitat. The only way to minimize human impact on the environment is by controlling the number of people. That means mandatory birth control such as is the policy in China. Mexico is not exactly a world leader in this area.

There are 4000 weather stations in the USA. The landmass of the USA is about 8,000,000 square kilometres. Therefore, there is one weather station for every 2,000 square kilometres.
Your claimed error of +- 0.18 C equates to +-0.06% The global average temperature is claimed as 286K.
100*0.18/286= 0.06%

If we assume a 99% confidence interval, a sample size of 4000, and an error of +-.18 K (or C), the standard deviation of the population must be 3*SD=0.18*SQ(4000)

Therefore, the supposed standard deviation of the temperature readings would be 1.2 K.

There is no way this can be true since temperatures can vary from as low as -40 in Alaska to +40 in the southwest.

Answer 3

Globing warming causes a warming in the atmosphere, which melts the polar caps in the arctic causing the cold water to migrate because the currents are all messed up by the massive amount of new water. The ice melting in the arctic causing more water also causes more precipitaion, which is why you got snow. The main misunderstanding that places seem to get colder is because global warming causes the cold seasons to get colder and the warm seasons to get warmer. It also shortens transitional seasons.

Answer 4

in case you prefer to acquire furnish money for climate learn, do you think of which you gets a cheque in case you say," i choose the supply, as i think of that i'm able to coach that the figures that the present paradigm is predicated upon are incorrect" ? the great environmentalist, David Bellamy, has been silenced, and refused airtime. there continues to be no shown causative hyperlink between the quantity of Co2 in the ambience, and an strengthen in international temperatures. The WWWF photos of the polar bears swimming have been taken in the Arctic summer season; whilst the ice cap partly melts, as they could no longer arise to image in the iciness. The ice replaced into too thick! The East-Anglian uni learn figures. "Oh! The figures do no longer journey our expectancies. Oh nicely. shop quiet. because of the fact all of us comprehend that we are precise." whilst the concept, and the religion is extra significant than squarely dealing with the valid doubts of countless non furnish-supported scientists, technology has been superceded by religious zealots. As Oliver Cromwell colourfully mentioned." I pray thee, in the bowels of Christ, evaluate that thou mayest be incorrect."

Answer 5

While certain areas may actually experience cooling, the Earth overall experiences warming.

Answer 6

I think its because the surface of the oceans warms up...creating the drastic changes in weather and climate.

Answer 7

Projected climate changes due to global warming have the potential to lead to future large-scale and possibly irreversible changes in our climate resulting in impacts at continental and global scales.

Examples of projected climate changes include:

significant slowing of the ocean circulation that transports warm water to the North Atlantic,
large reductions in the Greenland and West Antarctic Ice Sheets,
accelerated global warming due to carbon cycle feedbacks in the terrestrial biosphere, and
releases of terrestrial carbon from permafrost regions and methane from hydrates in coastal sediments.
The likelihood, magnitude, and timing of many of these changes is uncertain. However, the probability of one or more of these changes occurring is likely to increase with the rate, magnitude, and duration of climate change. Additionally, the US National Academy of Sciences has warned that "greenhouse warming and other human alterations of the earth system may increase the possibility of large, abrupt, and unwelcome regional or global climatic events. ... Future abrupt changes cannot be predicted with confidence, and climate surprises are to be expected." [1]

It is not possible to be certain whether there will be any positive benefits of Global Warming. What is known is that some significant negative impacts are projected and these drive most of the concern about global warming and motivates attempts to mitigate or adapt to the effects of global warming. Almost all scientists agree, however, that the negitive effects would out-weigh the positive effects.

Most of the consequences of global warming would result from one of three physical changes: sea level rise, higher local temperatures, and changes in rainfall patterns (Figure 1). Sea level is generally expected to rise 50-200 cm in the next century (Dean et al. 1987). Such a rise would inundate 7,000 square miles of dry land in the United States (an area the size of Massachusetts) and a similar amount of coastal wetlands; erode recreational beaches 100-200 meters; exacerbate coastal flooding; and increase the salinity of aquifers and estuaries (Titus 1989).
Global warming is the observed increase in the average temperature of the Earth's near surface air and oceans in recent decades and its projected continuation.

Global average near-surface atmospheric temperature rose 0.74 ± 0.18 °Celsius (1.3 ± 0.32 °Fahrenheit) in the last century. The prevailing scientific opinion on climate change is that "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations,"[1] which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Other phenomena such as solar variation and volcanoes have had smaller but non-negligible effects on global mean temperature since 1950.[2] While this conclusion represents the consensus of the scientific community, a few scientists disagree about the primary causes of the observed warming.

Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100.[1] The range of values reflects the use of differing future greenhouse gas emission scenarios as well as uncertainties regarding climate sensitivity. Although most studies focus on the period up to 2100, even if no further greenhouse gases were released after this date, warming and sea level rise would be expected to continue for more than a millennium, since carbon dioxide (CO2) has a long average atmospheric lifetime.

An increase in global temperatures can, in turn, cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. There may also be increases in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming. Other consequences include changes in agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the exact degree of climate change expected in the future, and especially how changes will vary from region to region across the globe. A hotly contested political and public debate also has yet to be resolved, regarding whether anything should be done, and what could be cost-effectively done to reduce or reverse future warming, or to deal with the expected consequences. Most national governments have signed and ratified the Kyoto Protocol aimed at combating global warming.

"An increasing body of observations gives a collective picture of a warming world and other changes in the climate system."

Answer 8

i send everybody who cares or who wants to know or who does not believe ,this mesage


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.

: i have seen lands that have been turned from jungle into desserts by people in a matter of a couple of years ,because of the slash and burn method used by settlers and expanding agriculture,and i have seen rivers dry up because of deforrestation in many places in Africa and Mexico ,

i live now by the side of a river in Mexico where,in 30 years 5 species of fish have become exstinct .
and part of the year the river is dry this is for longer every year because of over use of water by agriculture and as a result of deforrestation.

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


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
