The issue with stopping or reducing global warming is about risk and managing risk: Science still does not know the exact mechanism by which smoking and its associated chemicals causes cancer. What we do know is that smoking is the biggest risk factor in developing lung cancer. The more you smoke, the more your risk of getting lung cancer. Not everyone who smokes gets lung cancer, and not everyone who gets lung cancer has smoked.

Solution to mitigate global warming
What is thermosolar power, or "desert energy"?
Thermosolar energy means generating electricity from the heat of the
sun, and not, as photovoltaic panels do, from sunlight. Since a large
quantity of solar heat is required, evidently this must be done in the
desert. A short introduction in this promising technology to produce electricity from a renewable source:
The carbon dioxide emissions (carbon footprint) caused by our personal behavior is driven to a large extent by the type and quality of our nourishment. The amount of greenhouse gases caused by the production of food is different from one food type to the other (see table below). Worst is meat and in particular beef.
A environmental friendly and climate change friendly nourishment is characterised as follows:
How much CO2 is produced by atomic energy?
One of the few pros of nuclear power is the relatively low emission of carbon dioxide (CO2), one of the major causes of global warming. For this reason, it has been proposed as "the" method to mitigate the effects of climate change. However a recent life cycle analysis showed that nuclear power produces 4 to 10 times higher CO2 emissions per kWh electricity than renewable energies.

Is prevention of global warming possible? Or is only mitigation of global warming possible? How fast do changes in the carbon dioxide emissions affect the average temperature increase? What are the effects of some proposed global warming solutions?
We show the urgent need to act in order to be able to mitigate global warming. For this purpose, we simulate different scenarios for the future emissions of carbon dioxide (CO2) and calculate their effect on the rise of the average temperature on Earth.
As a result, it still seems to be possible to avoid the most devastating effects on our environment. However we must start acting immediately. The longer we are talking instead of acting, the more drastic measures are needed.
Global warming is not about the others, global warming is about us and our personal behaviour . Everyone must assume responsibility and bring down his or her personal contribution .
One of the major problems for our future is the ever growing number of people living on Earth. We are referring to this in several articles on this site. Below you can find first a graph about the population by geographical area and by year, starting in 1950 until the year 2050.
The second graph shows the population density by geographical area by year, i.e. the number of people living per square kilometre. Further down, we provide lists of the current and predicted population by country. Click on one of the links below to jump directly to a list or graph:
Electricity from nuclear energy is considered to be economical and very cost effective, in particular compared to electricity from renewable energy sources like wind, water, sun, biomass or geothermal energy.
There are two main reasons for the relative low cost of nuclear power:
- Research and development for nuclear applications has been financed by the government, therefore these costs don’t get transferred to the cost of electricity produced from nuclear power. However the cost of R&D for renewable energy sources is mostly financed privately and therefore added to the production cost. It is therefore included in the cost of renewable electricity.
- Nuclear power plants are underinsured for legal liability. The risk for nuclear catastrophes is not carried by the owner of the nuclear power plant, it is carried by the whole nation. Electricity from nuclear power would cost at least twice as much than today if operator companies of nuclear power plants were to insure the plants for the real risks.
It took more than 20 years to broadly accept that mankind is causing global warming with the emission of greenhouse gases. The drastic increase in the emission of CO2 (carbon dioxide) within the last 30 years caused by burning fossil fuels has been identified as the major reason for the change of temperature in the atmosphere.
More than 80% of the world-wide energy demand is currently supplied by the fossil fuels coal, oil or gas. It will be impossible to find alternative sources, which could replace fossil fuels in the short or medium term. The energy demand is simply too high.
- Why have warnings about climate change been ignored for more than 20 years?
- Why were ever more scientific evidence demanded to find the coherence of man-made CO2 emissions as cause of global warming? Wouldn't common sense have been reason enough to act?
In search for global warming solutions, people are suddenly asking for alternative energies. However, more than 80% of our energy is currently taken from the fossil sources oil, gas or coal. It is absolutely impossible to supply this much of energy from alternative sources within the next 10 to 20 years.
Therefore, we should first ask how much energy is really required to have a good quality of life, instead of taking our current energy consumption for granted or even indispensable. In a second step, we can then look for potential energy sources to fulfil this need.
