Danger signs are surfacing worldwide as temperatures increase (the last ten years have been the hottest years ever recorded causing glaciers and the polar ice caps to melt, coastal areas to flood and storms to become more severe). If left unchecked, global warming will continue to have a profound impact on our planet that will eventually cause catastrophic results. Fortunately, there are things each of us can do. Buildings -- including our homes -- are major contributors to greenhouse gases they’re responsible for up to 40% of all energy and resource use and approximately 1/3 of greenhouse gas emissions that cause global warming.
