The main gases that contribute to the greenhouse effect (the retention of heat from solar radiation in the Earth's lower atmosphere) are: water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
The global average surface temperature (over land and ocean) increased by an estimated 0.85 deg.C in the period from 1880 to 2012. That increase in global temperatures is mainly attributed to the increasing...
Overexposure to UV rays is a major risk factor for skin cancers and cataracts. Humans on Earth are exposed to UV radiation of various wavelengths, which can be subdivided in: UVA (320 to 400 nm) and UVB (290...
Natural resources are actual or potential sources of wealth that occur in nature, such as timber, water, fertile land, wildlife, minerals, metals, stones and hydrocarbons. Efficient use of limited natural...
Wind power is renewable, plentiful, and produces no greenhouse gas emissions, thus it is significantly less harmful to the environment as compared to power generated from fossil fuels. Key challenges to the...
The presence of carbon dioxide (CO2) in the atmosphere is one of the primary causes of the greenhouse effect. CO2 emissions come from a variety of natural sources; however, human-related emissions are...
The Montreal Protocol has reduced by 98% consumption of ODS's such as Chlorofluorocarbons (CFCs) and halons, which were widely used in: aerosol sprays (dry cleaning, fumigants), blowing agents for foams...
Supporting the long-term ecological balance of our planet is fundamental to the survival of the human species and other living organisms. Over the past few years, a number of initiatives have made a real...
