Just last week explorer opened a thread on the current heat in the atmosphere. This thread intends to say more and expatiate on weather issues. So relax and Enjoy.

WEATHER: Weather can be defined as the "snapshot" of the atmosphere at any given time
The ingredients that make up weather and which are essential to sustain life on earth are:

-Heat from the sun

-The atmosphere

-Moisture.

Weather only occurs in troposphere, the layer of air about 10-15km thick above the surface of the earth. The driving force behind our weather is the general circulation of the atmosphere caused by unequal heating of the earth’s surface.

The sun drives the system. The basic principle is that warm air rises and cool air falls. This principles applies on a global scale. Energy from the sun causes uneven heating of land and sea surfaces near the equator and evaporation from topical oceans. The heated air rises to the top of the troposphere and moves slowly away from the equator on the way it gradually loses heat and starts to sink back towards the earth’s surface.

The differences in air temperature and pressure over the world cause wind. The air at the equator is much warmer than at the poles. Nigeria lies close to the equator. Warm air expands and rises creating an area of low pressure, cold air is dense and sinks, creating an area of high pressure. But because the earth I spinning on its axis, the wind pattern becomes more complex. The circulation of these winds and the passage of high and low-pressure cells have major influence on climate. Therefore weather is the result of the coming together of different masses of air which have different temperatures, pressure and contain different amount of water.

Someone once quipped: “Everybody talks about the weather, but nobody does anything about it.” Indeed, it has always seemed that the weather is beyond our power to change in any way. Increasingly, however, many scientists no longer believe that. They say that the spewing of carbon dioxide and other gases into the atmosphere is bringing climate.

Lalasticlala, Did you know about this? Do the needful.

According to experts, what is the nature of this coming change? Probably the most authoritative answer comes from the Intergovernmental Panel on Climate Change (IPCC), which drew on the expertise of more than 2,500 climatologists, economists, and risk-analysis specialists from 80 countries. In 1995 report, the IPCC concluded that the earth’s climate is becoming warmer. During the next century, if things continue as they are, it is possible that the temperature could increase by as much as 3.5 degree Celsius.
While a few extra degree, may not sound like much worry about, a small temperature change in the world’s climate could be disastrous. The following is what many foresee for the coming century.


1. Regional Extremes in Weather: in some areas, droughts could become longer, while in others, rainfall could become heavier. Storms and floods could become more severe, hurricanes, more damaging. Though millions already die as a result of floods and famine, global warming could make death toll much higher.

2. Increased Risk to Health: Heat related illness and death could soar. According to the world health organization, global warming could also extend the range of insects bearing tropical diseases, such as malaria and dengue. In addition, reduced freshwater supplies because of changes in regional rainfall and snow fall could cause an increase in some waterborne and food-borne disease and parasites.

3. Natural Habitats Threatened: Forests and wetlands, which filter our air and water, could be put at risk by warmer temperatures and changes in rainfall. Forest fires could be more frequent and more intense.

4. Rising Sea Levels: Those living in low coastal areas would have to move unless costly projects were undertaken to hold back the sea. Some islands would be completely submerged.

5. Chaotic Weather: In a variety of ways, most of us rely on carbon-based fuels. We drive cars and other vehicles powered by gasoline or diesel fuels. We use electricity generated by power plants that consume coal, natural gas, or oil. We burn wood, charcoal, natural gas, and coal to cook or keep warm. All these activities add carbon dioxide to the atmosphere. This gas traps heat from sun. We also add heat trapping greenhouse gases to the atmosphere. Nitrous oxide is added from Nitrogen fertilizers used in Agriculture. Methane is emitted by rice paddies and cattle feedlots. Chlorofluorocarbons (CFCs) result from the manufacture of plastic foams and from other industrial processes. CFCs not only trap heat but also destroy earth’s Stratospheric Ozone Layer.

With the exception of CFCs, which are now regulated, these heat-trapping gases are being emitted into the atmosphere at ever increasing rates. This is due to the growing of energy use, industrial activity, and Agriculture. According to the Washington-based Environmental Protection Agency, humans presently spew six billion tonnes of carbon dioxide and other greenhouse gases into the atmosphere each year.

Scientists are generally quite confident about two things. First, in recent decades and centuries, the amount of carbon dioxide and other greenhouse gases in the atmosphere have increased. Second, over the last hundred years, the average surface temperature of the earth has also increased.

God Bless Nairaland
God bless the Earth.

Physics Sweet

Good post I wish to see you in the promise land soon but you would have add something about how olajumoke the bread seller turn model

Interesting..

Thank you sir

Lol, Olajumoke is now the password.

Oga Lalasticlala, Nairalanders needs this

omo the hot weather now adays fit make Tonto dike pitch black

Thanks. Great info.
