Global Climate Scenarios: Temperatures, Precipitation and Sea Levels

Part 9 of United States Climate Change Impact. Rising global temperature All climate models project that human-caused emissions of heat-trapping gases will cause further warming in the future. Based on scenarios that do not assume explicit climate policies to reduce greenhouse gas emissions, global average temperature is projected to rise by 2 to 11.5°F by […]

Global Climate Scenarios: Emissions

Part 8 of United States Climate Change Impact. Some continued warming of the planet is projected over the next few decades due to past emissions. Choices made now will influence the amount of future warming. Lower levels of heat-trapping emissions will yield less future warming, while higher levels will result in more warming, and more […]

Rising Temperatures, Carbon release and uptake and Ocean Acidification

Part 5 of United States Climate Change Impact. Carbon release and uptake Once carbon dioxide is emitted to the atmosphere, some of it is absorbed by the oceans and taken up by vegetation, although this storage may be temporary. About 45 percent of the carbon dioxide emitted by human activities in the last 50 years […]

Why Drive an Advanced or Alternative Fuel Vehicle?

Part 1 of Advanced Technology and Alternative Fuel Vehicles. Transportation accounts for more than 67% of oil consumption in the USA-more than it produces. Today, our country imports more than 54 percent of its oil, and suggested that this could increase to 75% by 2010. According to the U.S. Federal Highway Administration, the average vehicle […]

Advanced Technology and Alternative Fuel Vehicles

The surveys indicate that Americans are concerned about the environment, global warming, and related topics. Yet many do not realize that cars and trucks that guides are an important source of these problems, and that there are other choices they can do today. Most of us drive or ride vehicles that are powered by petroleum-based […]

Operating a heat pump

Part 6 of Air-Source Heat Pumps. Like combustion heating systems, you control heat pumps using thermostats. If you leave and return at regular times everyday, you’ll save money by using automatic thermostats, which minimize energy use during the times the home is unoccupied. However, choosing an automatic thermostat’s reactivation time requires considering the duration of […]

Cooling Your Home Naturally

Part 1 of Cool Your Home Naturally. Keeping cool indoors when it is hot outdoors is a problem. The sun beating down on our homes causes indoor temperatures to rise to uncomfortable levels. Air conditioning provides some relief. But the initial costs of installing an air conditioner and the electricity costs to run it can […]
