Global warming

As hard as it may be to believe on the chilliest days of the year, the Earth is getting warmer, and that's not a good thing. Global warming refers to a rise in the long-term average temperature of the Earth and the troposphere (the lower atmosphere) due to natural causes and human activities, particularly the emissions of greenhouse gases from the burning of fossil fuels. While the Earth has experienced warming trends in the past, this episode is occurring at an accelerated pace and the effects are already in evidence: temperature extremes, rising sea levels, and wildlife extinction among them.

Word of the Day
   Natural ventilation

You feel this effect every time you throw open a few windows in the house: Natural ventilation moves air into and out of a building through passive means-using forces such as wind and pressure differences-instead of mechanical air-conditioning systems or fans. Strategically placed windows and vents provide air supply and exhaust. Good natural ventilation can save energy and improve indoor air quality. Not only an option at home, natural ventilation is increasingly being incorporated into commercial HVAC systems as an energy-saving technique, for example by allowing fresh outdoor air in during the coolest hours of the day.
