Global Warming

Christophe Catesson asked:


A report of the effects of global warming on health published by WHO, has estimated around one million fifty thousand deaths every year due to global warming. Further it declared that each year five million people are suffering from health problems and diseases caused for this global warming. The rising concern over this matter has led many scientists and researchers to take a deeper look and prepare a plan to save human civilization from this onslaught.

Global warming has caused changes in temperature, ocean current flow, sea level, ecosystem, economy, agriculture, industry, settlements and related to all these - the health and living. Warmer world has created congenial atmosphere for the breeding and life expanse of various virus, bacteria and carriers of infectious diseases. Few evidences of global warming leaving negative effects on human health are -

- The vectors distribution of infectious diseases have been altered for global warming.

- Heat wave resulted for global warming are causing deaths.

- The seasonal distribution of few species of allergenic pollen have been altered for global warming.

- Various extreme conditions of global warming like droughts, heat and cold wave, storm, flood, fire will increase the death tolls as well as injuries and diseases.

- Malnutrition and disordered development of children are few long term results of global warming.

- Global warming will cause increase of malaria, diarrhea, cholera, dengue, encephalitis and other diseases.

- There will be constant rising rate of mortality due to ground level ozone related diseases as well as high cardio respiratory morbidity for global warming.

Thus global warming will affect human health in two major ways - with extreme weather condition and with rising infectious diseases. IPCC in a study of one of the most global warming affected area of Illionis, Chicago, has provided an apprehensive report that by 2020 extreme climate condition like heat wave will raise the climate average deaths to 400 and to 497 by 2050 from the present average of 191. European heat wave of 2003 is an example of its severity. Heat waves will even cause cardio respiratory complications resulting to high rate of deaths.

The results of ill health due to global warming and infectious diseases are already evident. Houston as well as many tropical countries are experiencing frequent outbreak of malaria, dengue and other encephalitis diseases. Even colder regions like Michigan, New Jersey, New York, Queens are severely suffering from malaria since 1990 as a result of global warming. McAllen of Texas also suffered a dengue epidemic in 1995. Florida, New Oreleans, Arizona, Mississippi, Texas, Colorado, and California - all are experiencing encephalitis epidemic for global warming since 1987. According to IPCC, 65% of world population will suffer from high risk of infectious diseases in near future. The risk itself will be increased by 20%, only as a result of global warming.

Facing such an impending calamity due to global warming, the requirement of proper planning and organized adaptation to new and changing condition has received a new dimension. Along with urgent and basic adaptation practices to fight the immediate effects, a longer planning and elaborate gradual methodology are also necessary to address the severity of future conditions resulted from global warming. A participatory approach to the holistic development of human health is expected to sober down the effects of global warming on health to some extent.

Joost Hoogstrate asked:


Have you ever listened to discussions and read articles about global warming and wondered why the resource person or the writer appears so emphatic and urgent in their call for fighting it? Well that is because global warming is an urgent problem that needs immediate action and resolution before it gets worse and could spell the end of human life and civilization as we see it today.

Broadly speaking, global warming is the steady increase of the atmosphere’s and ocean’s average temperature. And before you go saying ‘Big deal’ to yourself and scoff at the near-catastrophic predictions made by scientists and advocates, consider first some of the expected effects of global warming to our environment and to our very lives.

One of the most pronounced effects of global warming would be glacial retreat, in which glaciers in the Arctic region may be steadily melting. This translates to elevation of sea levels all over the world, raising concerns over obliteration of small islands and even countries. Global warming is also attributed to influence precipitation, leading to the possibility of increased flooding in some parts of the world and increased drought elsewhere. What’s scary about these projected changes is the complete inability of man to counteract and prevent them once these events start happening.

But then again, global warming effects are not solely manifested in the environment. Consider the effect of increased drought and flooding to food supply, and ultimately, to food consumption. Agriculture is one large sector expecting to bear the worst of the brunt of global warming, with lesser and lesser produce and crops expected to be harvested in the next decade or so. Now that is really scary, considering we all get a large portion of our food supply from farms.

Weather experts are also predicting extreme weather events due to global warming, ranging from severe snowstorms to intense cyclones and hurricanes in tropical areas.

The increase in the average temperature of oceans in our planet also means dwindling in the supply of our other food source. The rest of the world might not come to realize how fragile most of the sea organisms are and expected changes in temperature would bring about extinction to most of them. Carbon dioxide, the main culprit of global warming, is also expected to acidify ocean waters, leading to more extinction and disruption of the food web.

It is also worth considering the impact of global warming on human health as well. With increasing surface temperature, heat waves are expected to occur more frequently, possibly endangering children and the elderly. Many pathogens proliferate much faster in warm environment. Increasing atmospheric temperature could very well mean faster proliferation of these pathogens that would cause numerous diseases and illnesses to humans. There is also expected spread of fatal tropical diseases as the world becomes warmer and warmer, placing those living in temperate regions at higher risks.

The mentioned risks and dangers are but overviews of the complexity and gravity of the problem that is global warming. A lot of resources and references have been published and produced on the subject matter and it’s time people should sit up and make effort to learn more. With increasing knowledge and understanding, the fight against global warming would no longer seem to be overwhelming and insurmountable. And as cliché as it may sound, this is one fight nobody can ever win alone, so concerted efforts are certainly needed and cooperation from all sectors would be very much welcome.

Ernie Fitzpatrick asked:


I wonder what Al Gore will do when he finally realizes that the global warming hype is just that? I wonder if Barack Obama will wise up the global warming implications as well. Heavy snow and record low temperatures are being seen around the globe and it’s not just because it’s winter, nor because we just crossed the winter solstice.

The Pacific Decadal Oscillation (PDO) is going to wreck havoc with Al’s theory as well as cause mjor problems for California in the ensuing years. PDO is a long-lived El Niño-like pattern of Pacific climate variability. While the two climate oscillations have similar spatial climate fingerprints, they have very  a different behavior in time. Fisheries scientist Steven Hare coined the term “Pacific Decadal Oscillation” (PDO) in 1996 while researching connections between Alaska salmon production cycles and Pacific climate.

Here’s what non-biased climatologists see.

The alleged global warming is in for about 30 years of cooling according to NASA, one of the leading global warming theory advocates. Who’s a person to believe? NASA has confirmed that a developing natural climate pattern will likely result in much colder temperatures, according to Marc Shepherd, writing in the April 30 American Thinker. He adds that NASA was also quick to point out that such natural phenomena should not confuse the issue of manmade greenhouse gas induced global warming which apparently will be going on behind the scenes while our teeth are chattering from a decade and a half long cold spell.

A cool-water anomaly known as La Niña occupied the tropical Pacific Ocean throughout 2007 and early 2008. In April 2008, scientists at NASA’s Jet Propulsion Laboratory announced that while the La Niña was weakening, the Pacific decadal Oscillation – a larger-scale, Slower-cycling ocean pattern – had shifted to its cool phase.” Will Al Gore believe this?

This shift in the PDO, which could last for 20 or 30 years, can have significant implications for global climate, affecting Pacific and Atlantic hurricane activity, droughts and flooding around the Pacific basin, the productivity of marine ecosystems and global land temperature patterns. Look out California agriculture. The wine industry, fruits and nut growers will be hit with a shorter growing season and more threats of frost, among other things. 

In 1905, the PDO switched to a warm phase, in 1946, PDO switched to a cool phase, and in 1977, PDO switched to a warm phase again. Now they tell us! Says NASA: “Natural, large-scale climate patterns like the PDO and El Niño-La Niña are superimposed on global warming caused by increasing concentrations of greenhouse gases and landscape changes like deforestation. According to Josh Willis, JPL oceanographer and climate scientist, ‘These natural climate phenomena can sometimes hide global warming caused by human activities. Or they can have the opposite effect of accentuating it.’”

In other words, CO2 is secretly warming the planet. Or maybe not. Maybe it’s due to things in the universe since ALL of the planets in our solar system are warming up. Global warming? Maybe, but not of the genre that Al Gore speaks.

Christophe Catesson asked:

For a long time it has been believed that the effects of global warming on agriculture and food supply is going to be a positive one. This is because the rising level of carbon-dioxide resulted for global warming will help the greeneries for photosynthesis.

Thus there will be a rise of agricultural production and food supply. The theorem received a boost after the evidence of a sharp rise of barley production as one of the effects of global warming in Iceland which was quite impossible even few years ago.

But more recent experiments and researches have revealed that the effects of global warming on agriculture and food supply are not that good after all. AN UNEP 2001 report on the global warming has predicted that USA is going to have more droughts, floods, landslides and storms.

Winter will gradually be shortened and sobered down, while summer will rise in expansion and severity. Along with this heavy rain, big storm, heavy snowfall, high sea level, increasing coastal erosion and other problems will occur.

Though as one of the effects of global warming, the overall food supply and production level is supposed to rise in USA, but the Great Plains will suffer with more droughts resulting for global warming.

Even now many effects of global warming on agriculture and food supply have been perceived. The popular maple syrup production of North east USA has diminished by 10%, moving its production zone to farther north for shorter and warmer winter.

On the other hand as one of the effects of global warming the south west USA is suffering from a water shortage which will increase in coming days. The zone has become dry for any standard agricultural production with an apprehension of resettling Dust Bowl of 1930s’ by the year 2030 for global warming.

Following a report of IPCC on the global warming, California’s snow covered Sierra Mountains can reduce in near future by up to 60-90%. This will create dire water shortage in summer, making the Central Valley area unsuitable for agricultural production for global warming. The State University of Colorado has declared that the area is going to be less productive due to effects of global warming on agriculture and food supply.

As the effects of global warming, the food supply production in Florida is going to suffer a lot due to frequent and large scale floods. Also one of the most profitable agricultural products of USA - corn will suffer a bad condition due to dry and hot atmosphere for global warming.

As another example of the effects of global warming on agriculture and food supply - with the rise of temperature by 3 to 11 degrees in this century, the production rate of the main crops - the rice, corn, wheat, barley, soybeans and sorghum - will be cut down by 3-5% for each point rise of temperature for global warming.

However with all these effects of global warming on agriculture and food supply, new attempts have been made to adjust the agricultural and food production method according to the changing atmosphere. So to fight the effects of global warming, the researchers have established new methods of production with continuous revision of models. But still the best possible process to reduce the effects of global warming on agriculture and food supply is to be established.
