Effects of global warming by region (IPCC)

A new report of IPCC (Intergovernmental Panel on Climate Change) including an update on predicted effects of global warming by geographical regions has been released in April 2007. This report does confirm the cause and effects of global warming, which have already been know for years.

In this article, the effects of global warming by geographical area are summarized. Geographical regions looked at individually are Africa, Asia, Australia and New Zealand, Europe, Latin America, North America, Polar regions, small islands.

Global warming effects – mitigate temperature increase

Global warming solution with 1.9% reduction of CO2 emissions per year

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 .

 

Nuclear power phase-out pros and cons

Nuclear phase-out means the discontinuation of usage of nuclear power for electrical energy production. Usually because of concerns about nuclear energy, existing plants are either shut down or not renewed after being retired.

Many European countries have decided to phase-out nuclear power, for details see further below. Under the umbrella of global warming, lobbying organizations of the atomic industry are putting high pressure on several governments to postpone the planned shut down of nuclear power stations or even to cancel the phase-out altogether. Their main argument is the relatively low CO2 emission of nuclear power compared to fossil fuels coal, oil and natural gas. However nuclear energy should rather be compared to sustainable energies and not to fossils.

The general pros and cons of nuclear power are discussed on a separate page. Here we concentrate on the pros and cons of nuclear phase-out.

Growing world population

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:

Effects of global warming – IPCC draft

This new report of IPCC will basically confirm the cause and effects of global
warming, which have already been know for years. The evidence of
earlier predictions is much increased and approaching certainty,
however.

 

About the cost advantage of nuclear energy

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.

 

The main cause of global warming

One of the main causes of global warming is our thoughtless treatment of NatureIt 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?

Pros and cons of global warming

Is global warming man-made?

There is no doubt any more: Global warming (climate change) has been caused by human beings through the high emission of so called greenhouse gases (mainly carbon dioxide CO2). Carbon dioxide is inevitably emitted when fossil fuels (coal, natural gas or oil) are burned.

This finding has been accepted by hundreds of climate experts and governments world-wide. No one can ignore climate change any more and call global warming "a bad illusion of some greens".

Global warming solutions – sensible energy consumption

Global warming solutions: Energy mix 2003In 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.

Cause and effects of global warming – IPCC report

IPCC Fourth Assessment Report "Climate Change 2007" about the cause and effects of global warming. This is the report many politicians are currently referring to and calling (at last!) for actions. A summary of the report can be found on the website of IPCC, see here .

The report does not really reveal new information about the causes and effects of global warming. This report however confirms that mankind through the emission of greenhouse gases (in particular carbon dioxide, CO2) is the cause of global warming. Mitigation of global warming will only be possible with a drastic reduction of the world-wide emission of carbon dioxide (CO2). Carbon dioxide is produced when fossil fuels (coal, oil and gas) are burned.

The important thing about this report is the fact that its findings and conclusions have been accepted by hundreds of climate experts and governments world-wide. There is no doubt any more that urgent action is needed, nobody can ignore climate change any more and call global warming "an illusion of greens".
