Radiation wavelength and greenhouse effect

This article tries to answer a question about the greenhouse effect: "Greenhouse gases prevent the infrared rays from leaving the Earth's atmosphere, but why do they not prevent additional solar radiation from entering the atmosphere?"

The key is the different wavelength (or different frequency) of solar light and infrared light. Let's have a look at the greenhouse effect (see also the graph about radion transmitted by atmosphere below):

CO2 emissions for shipping of goods

Globalization makes it easy to send goods around the world. The cost for shipping goods has never been as low as now. However, the choice of the means of transportation does severely influence the amount of CO2 emitted for the transportation of goods.
The following table shows the amount of CO2 (in grams) emitted per metric ton of freight and per km of transportation:

Ocean acidification - another effect of global warming

Fossil fuel combustion and industrial processes release over six billion metric tons of carbon into the atmosphere each year. The consequences of these greenhouse gas emissions are often discussed in terms of rising global temperatures, but global warming is not the only threat from increased atmospheric concentrations of carbon dioxide (CO2). Ocean acidification, which occurs when CO2 in the atmosphere reacts with water to create carbonic acid, has already increased ocean acidity by 30 percent. Although the chemistry of this effect is well understood and not much debated, the full consequences of ocean acidification for marine ecosystems and human well-being are only beginning to be revealed.

Global carbon cycle and climate change

Life processes are fuelled by carbon compounds which are oxidized to CO2 (carbon dioxide), the latter is exhaled by all animals and plants. Conversely, CO2 is assimilated by plants during photosynthesis to build new carbon compounds. See also this comment about photosynthesis and global warming.

The future of civil nuclear power applications

In July 2007, Oxford Research Group in London released a report about the future of civil nuclear power applications and about the threat of nuclear proliferation. It's title is "Too hot to handle?" A link to the full article is provided at the end of this text.

Here are the conclusions of the report:

The best Religion - Self determination

Many people have now and then some doubts whether their own religion is the best or whether it would be better to convert to a different belief. Others turn away from all religions and some even reject any kind of spirituality. Don't we need religions any more? Are they a concept of the past?

There has always been a certain rivalry between many religions because in the end they all care about the same „clients". An increasing number of followers for a religion automatically increases its influence and power and in most cases also its financial resources.

Reincarnation of our soul - rebirth

Talking about reincarnation or rebirth is automatically talking about the life cycles of the human soul: Long time ago, our souls left their divine origin to gain some experiences in the material world. It was clear from the very beginning that the souls would eventually return back to their divine origin, however. Therefore all our souls have the strong desire to return back to where they originally came from, respectively to their original divine state.

Get a feeling how mitigation of global warming can be affected


Run your own simulations of global warming with the attached spreadsheets!

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?
