Today I decided to revisit an earlier blog subject that has gotten a lot of attention, and that was on the subject of Global Warming.  Now for those who do not know me, I am not a proponent of the idea that mankind is harming the atmosphere with the emissions of fossil fuels.  The same agency that was given the task to monitor these effects on the world’s weather is the same group of scientists who preach this continued “gloom and doom” reporting of so called disastrous results, if we do not stop the release of hydrocarbons into our atmosphere.

This is some of what they say:

It is no surprise that global warming is a result of human-induced pollution.

The main immediate global warming cause is the increased concentration of greenhouse gases in the atmosphere.  Some of these greenhouse gases end up in the atmosphere, where they trap a certain amount of originally solar energy (which would have otherwise escaped to space), and thus radiate this energy back to the Earth raising the planet’s average temperature.

The first fundamental global warming cause is an absolute dependence of the modern human society on the burning of fossil fuels, which is the most important source of greenhouse gas emissions.

Carbon dioxide (CO2) is the main greenhouse gas emitted as a by-product of fossil fuel combustion. This gas is the most important immediate global warming cause.  The carbon content of past living organisms has been stored in the form of fossil fuels – oil, gas and coal.  The amounts of these fuels burned to provide society with energy, represent the carbon captured by photosynthesis over millions of years. So, by burning them…we have returned carbon dioxide to the atmosphere thousands of times faster than the rate at which it was removed by the early tropical forests.”

We also have some other industry-related activities which are also significant sources of greenhouse gases such as fluorocarbons, carbon dioxide as well as small amounts of methane (CH4) and nitrous oxide (N2O).  The products whose manufacturing causes the emission of these gases include cement, minerals, chemicals, metals.

The second fundamental global warming cause is related to the way we use our land and the effects of waste management.  Most common land use activities include: Modern agricultural practices employed to breed animals, grow cereals, fruits & vegetables and other foods, all for human consumption and the clearance of land for timber sales or for the expansion of human settlements / cattle ranches.  A very important element of this area is tropical deforestation, especially by way of forest fires, which alongside other pollutants causes the release of carbon dioxide.

Global warming potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is 1 by definition). A GWP is calculated over a specific time interval and the value of this must be stated whenever a GWP is quoted or else the value is meaningless. (Wikipedia)The energy sector is by far the largest emitter of greenhouse gases (70%) followed by the land use sector (23%), waste management (4%) and industrial processes (3%).

Power generation is the biggest source of greenhouse gases (specifically, CO2) within the energy sector, with 31% of the energy sector’s total emissions.

Industrial sector generates around 15% of the energy sector’s total emissions and includes fossil fuel combustion to power primarily manufacturing industries such as iron & steel, chemical, paper production and other industries.

Road transport is, of course, another major generator of greenhouse emissions (15% of the total amount), as still a vast majority of road vehicles around the world are currently powered by liquid oil.

These three sub-sectors – power generation, industrial sector and road transport – produce slightly more than 60% of the total greenhouse gas emissions related to the energy sector.

Deforestation causes 31% of the total land use emissions and is a very serious problem not only from the point of view of global warming but also in respect of irreversible plant and animal diversity loss with negative consequences for many different groups of people and the planet as a whole.

Enteric fermentation by farm animals (such as cattle, sheep, goats etc) is another important source of greenhouse emissions (21% of total land use emissions).  Enteric fermentation is a process through which animals produce methane in their digestive tract and then either belch it or pass it out as gas.

Rice cultivation is one more major cause of methane emissions, producing 10% of total land use emissions.

It’s interesting to note that though global warming has been known to be a problem since the 1980s, they still predict an increase in the global temperature in the range of 1 to 2 degrees with terrible effects on mankind.

 

Here is what I have to say:

If you follow the “Gloom and Doom” believers in “Global Warming” our temperatures should be steadily rising due to the “greenhouse effect”, but look at the data that I collected from the National Weather Service.  Just compare the Maximum temperature for the above date, in my hometown.

 

In 1960 it was 57 degrees, it climbed to 69.1 degrees in 1970, and it climbed again to 84 degrees in 1980.  It should of kept climbing, but instead, it dropped to 61.9 degrees in 1990.  In the year 2000, it again jumped to 86 degrees, but it then dropped to 57.9 degrees in 2010 and further dropped to 55 degrees in 2013.

So, you decide if you believe in global warming, or not.
