general texts related to global warming (causes, effects, mitigation)
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.
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:
A number of people have asked about the implications of using plastic bags on the personal carbon footprint as well as on the environment in general. There are some comparisons between paper bags and plastic bags available which clearly show that it all depends on how many times these plastic or paper bags are being used.
Littering is probably the severest problem related to plastic bags. Nevertheless let's now have a look at the carbon dioxide (CO2) emissions for the production and incineration of plastic bags.
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.
Summary of Eurobarometer survey published on March 13, 2008. The report shows that Europeans are increasingly aware of the role played by the environment in their daily lives. More than 95% of European citizens feel that it is important to protect the environment. Some 80% also feel it influences their quality of life and consider that they have a role to play in protecting it. Climate change (global warming) tops the list of Europeans' environmental concerns, followed by pollution and man-made disasters.
A majority are also uneasy about the use of genetically-modified organisms (GMOs) in agriculture.
With continued population growth, increased per capita consumption, and anticipated climate change, the global water situation appears bleak. Since water scarcity is a highly localized issue determined by regional climatic and demographic factors, a single solution will not solve all of the world's water scarcity problems.
However, improved management, more water efficient technologies, and support for the world's most vulnerable countries and ecosystems will likely play leading roles. According to the UN-backed World Commission on Water, coping with water scarcity will require global investment of $100 billion per year. Willingness to invest this sum will be vital to the future of human well-being and economic development in all countries of the world.
«Aiding oil, harming the climate» is a new report from the organisation "Oil Change International", which shows dramatically that the major investments still go into the oil, gas and coal sector instead of renewable energies. For more than 25 years, wealthy countries have been using aid and other foreign assistance to subsidize the expansion of the international oil industry, a practice known as “Oil Aid”. It is impossible to actively subsidize the expansion of the oil industry and effectively fight global warming at the same time.
