The temperature in the inner urban areas of Honk Kong, China, is predicted to rise by two to three degrees Celsius in the next 30 years, according to researchers at the Department of Land Surveying and Geo-Informatics (LSGI) of the Hong Kong Polytechnic University (PolyU).
At more than 11,000 feet above sea level, very important ecosystems known as páramos exist. These kinds of ecosystems are only found in Central and South America and resemble a sort of alpine archipelago, each a link between distinct island ecosystems that exist nowhere else on the planet.
Most cities brew up a blend of gases that covers the urban area like a dome. The top of most buildings can sit outside or inside this metropolitan atmosphere, depending on the weather. Ecologists are sampling sites around Boston in order to compare levels of carbon dioxide, carbon monoxide, methane, and water vapor.
Megacities are usually defined by a total population in excess of 10 million, with an additional component of population density. Rapid urbanization will take a heavy toll on the infrastructure of local governments, if city planners don’t incorporate ways to tackle air pollution.
