Everybody speaks about it – but actually what is the Definition for Global Warming ? Worldwide, endless summers, the whole year?? A pool for everyone?
Well, though the idea of perpetual summer sounds good to me – though I would miss winter and skiing soon – it ain’t not a pleasant topic.
Actually, the so Called Global Warming is very threatening, at least the scenarios painted by most scientists right now. And I am sure, if we really experienced every year being warmer than the last one for years, Earth would become uninhabitable.
For sure you are aware that the glaciers are melting, the poles are melting and that it is predicted that the Ocean levels will rise.
Even a rise of Earth’s temperature of only 1°C or 2°C will have dramatic effects.
The difference between an Ice age (the last – though “small” one – took place in the 14th century, the last “big” one about 20.000 years ago) and our climate is only a few degrees of average temperature. Satellites show sources and sinks of atmospheric carbon dioxide across Earth, measured here in 2003. High concentrations are shown in red and lower concentrations are shown in blue. Credit: NASA
Official Definition for Global Warming
The US National Weather service gives the Definition for Global Warming as
“an overall increase in world temperatures which may be caused by additional heat being trapped by greenhouse gases.”
The US Environmental Protection Agency puts the Definition as
“an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both natural and human induced. In common usage, “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities. See climate change, greenhouse effect, enhanced greenhouse effect, radiative forcing, troposphere.”
In Wikipedia the Definition is
“the average warming of the Earth’s near-surface air and oceans since the 1950s and its expected continuation. A recent report says that the world’s surface warmed 0.74 Â± 0.18 Â°C (1.33 Â± 0.32 Â°F) sometime between 1900 AD – 2000 AD. Most of the observed warmth since the 1950s was caused by the rising levels of greenhouse gases, which results from everyday actions made by people such as destroying forests and the burning of gasoline, fuel or diesel for cars, trucks, planes, cargo ships, and factories just to name a few.”
And finally NASA defines Global Warming as
“an increase in the average temperature of Earth’s surface. Since the late 1800’s, the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8 degrees C). Many experts estimate that the average temperature will rise an additional 2.5 to 10.4 degrees F (1.4 to 5.8 degrees C) by 2100. That rate of increase would be much larger than most past rates of increase.”

So the ’experts’ agree that by burning fossil fuels and deforesting wide areas of our planet the CO2 levels are rising since about 150 years. These gases have the so called Greenhouse Effect.
But that is only part of the picture. Other experts agree that our emissions have nothing to do with the Global Warming and that there hasn’t been Global Warming since the any 1990. They call the IPCC’s and NASA’S research faulty. A real battle is going on.
The Coming Global Cooling
Please let me state here that I believe that the idea of Global Warming will not endure. It will be worse…we will be getting a global cooling, and so getting independent from expensive energy is so even more important.
Because you will need more energy to heat your home when the winter is longer than ever in our lifetime.
This website is about becoming independent from the then freezing energy grid with power outages.
