THE ROLE PLAYED BY MASS MEDIA IN SPREADING GLOBAL WARMING

MASS MEDIA AND GLOBAL WARMING

We are told with media such as google, Encyclopedia.com | Free Online Encyclopedia to expect the worst, and to prepare ourselves for great sacrifices and sweeping changes that will effect us not just at the environmental level, but also at a very real economic level. My concern here is why other medias are not used especially in our daily lives to communicate with us about global warming, what is happening to the uneducated people about this issues. Not everyone in the world knows about global  warming especially if you didn't go to school at all or you did not do science or geography  at school or other institutions. Why is global warming not well known and understood by people like the HIV and AIDS issue in the world because it covers everyone whether young or old and rich or poor, what is happening to the influence of the media such as television, newspapers online news and workshops that we can find in our everyday life. Our states in the world they only talk about it once it has acted in a harmful way why, is it because of they don't want to scary the publics or people or live them with everyday life fear, if that's the case then when are we facing the reality?

Extreme Weather Conditions Caused by Global Warming and Deseases


A warmer world already seems to be producing a sicker world because of the extremely weather conditions caused by global warming, Malaria epidemics have occurred in highland areas where cooler weather has gone up, also flu. During a heat wave, it's important to know and be able to recognise the signs and symptoms of a heat-related illness. There are different types of heat-related illnesses, ranging from those that cause temporary discomfort to the generally fatal condition known as heat stroke. In all heat-related illnesses, the symptoms appear when a person is exposed to extreme temperatures.

Here are the symptoms of heat-related illnesses:
1. Heat Rash: Heat rash is a skin irritation caused by excessive sweating during hot, humid weather. It can occur at any age. Heat rash looks like a red cluster of pimples or small blisters.

 2. Heat exhaustion: Heat exhaustion is a warning that the body is getting too hot. Those most prone to  heat exhaustion include elderly people, people with high blood pressure, and people working or exercising in a hot environment. A person with heat exhaustion may be thirsty, giddy, weak, uncoordinated, nauseous, and sweating profusely. As with heat syncope and heat cramps, the body temperature is usually normal in heat exhaustion. The heart rate (pulse rate) is normal or elevated. The skin is usually cold and clammy.

 3. Heat stroke: Heat stroke is a serious, life-threatening condition that occurs when the body loses its ability to control its temperature. Victims of heat stroke almost always die, so immediate medical attention is essential when problems first begin. In heat stroke, a person develops a fever that rapidly rises to dangerous levels within minutes. A person with heat stroke usually has a body temperature above 104 F (40 C), but the temperature may rise even higher. Other symptoms and signs of heat stroke may include confusion, combativeness, bizarre behaviour, feeling faint, staggering, strong rapid pulse, dry flushed skin, and lack of sweating. Delirium or coma can also result from heat stroke. by Melissa Conrad Stöppler, MD.  Global warming it has a very big negative effect into our life and the fact that is already in action I do not know what  can be done or do to stop its action.

GLOBAL WARMING CHANGING SEASON



 Global Warming changing Seasons 


Time Science: Andrew Brown in the ice.
 The Earth's seasons have shifted back in the calendar year, with the hottest and coldest days of the years now occurring almost two days earlier, a new study finds. This shift could be the work of global warming, the researchers say. To figure this out, scientists at the University of California, Berkeley and Harvard studied temperature data from 1850 to 2007 compiled by the University of East Anglia's Climate Research Unit in the United Kingdom. They found that temperatures over land in the 100-year period between 1850 and 1950 showed a simple, natural pattern of variability, with the hottest day of the year in the Northern Hemisphere landing around July  But from the mid-1950s onward (the period when global average temperatures began to raise the hottest day came 1.7 days. In temperate areas with four seasons, the growing season would be longer with more precipitation. This could be beneficial in many ways for these areas. However, less temperate parts of the world would likely see an increase in temperature and a sharp decrease in precipitation, causing long droughts and potentially creating deserts (Andrea Thompson). As we can all see it is proven that global warming is changing the seasons, ain't you very suprise that nowadays, like now we already experiencing winter whereby it was supposed to start next month which is winter exactly and the fact that Snowfall for 6 hrs ending Fri 13 Apr at 8am Local Time in South Africa also the fact that winter last longer than any other seasons?

MYTHS AND FACTS ABOUT GLOBAL WARMING








  • Peter C Glover
MYTH :Global temperatures are rising at a rapid, unprecedented rate.

FACT: Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures. Average ground station readings do show a mild warming of 0.6 to 0.8Cover the last 100 years, which is well within the natural variations recorded in the last millennium. The ground station network suffers from an uneven distribution across the globe; the stations are preferentially located in growing urban and industrial areas ("heat islands"), which show substantially higher readings than adjacent rural areas ("land use effects").
There has been no catastrophic warming recorded.

MYTH : The "hockey stick" graph proves that the earth has experienced a steady, very gradual temperature increase for 1000 years, then recently began a sudden increase.

FACT: Significant changes in climate have continually occurred throughout geologic time. For instance, the Medieval Warm Period, from around 1000 to1200 AD (when the Vikings farmed on Greenland) was followed by a period known as the Little Ice Age. Since the end of the 17th Century the "average global temperature" has been rising at the low steady rate mentioned above; although from 1940 – 1970 temperatures actually dropped, leading to a Global Cooling scare.
The "hockey stick", a poster boy of both the UN's IPCC and Canada's Environment Department, ignores historical recorded climatic swings, and has now also been proven to be flawed and statistically unreliable as well. It is a computer construct and a faulty one at that.

MYTH : Human produced carbon dioxide has increased over the last 100 years, adding to the Greenhouse effect, thus warming the earth.

FACT: Carbon dioxide levels have indeed changed for various reasons, human and otherwise, just as they have throughout geologic time. Since the beginning of the industrial revolution, the CO2 content of the atmosphere has increased. The RATE of growth during this period has also increased from about 0.2% per year to the present rate of about 0.4% per year,which growth rate has now been constant for the past 25 years. However, there is no proof that CO2 is the main driver of global warming. As measured in ice cores dated over many thousands of years, CO2 levels move up and down AFTER the temperature has done so, and thus are the RESULT OF, NOT THE CAUSE of warming. Geological field work in recent sediments confirms this causal relationship. There is solid evidence that, as temperatures move up and down naturally and cyclically through solar radiation, orbital and galactic influences, the warming surface layers of the earth's oceans expel more CO2 as a result. 

MYTH :  Computer models verify that CO2 increases will cause significant global warming.

FACT: Computer models can be made to "verify" anything by changing some of the 5 million input parameters or any of a multitude of negative and positive feedbacks in the program used.. They do not "prove" anything. Also, computer models predicting global warming are incapable of properly including the effects of the sun, cosmic rays and the clouds. The sun is a major cause of temperature variation on the earth surface as its received radiation changes all the time, This happens largely in cyclical fashion. The number and the lengths in time of sunspots can be correlated very closely with average temperatures on earth, e.g. the Little Ice Age and the Medieval Warm Period. Varying intensity of solar heat radiation affects the surface temperature of the oceans and the currents. Warmer ocean water expels gases, some of which are CO2. Solar radiation interferes with the cosmic ray flux, thus influencing the amount ionized nuclei which control cloud cover. Is it the under grounds heat causing the sea level or temperature to rise and why the sun cant make the glacier to melt also looking at these facts and myths about global warming do people learn or know about them like the HIV/AIDS programmes?
