Prior to the industrial revolution the level was 280 parts per million.</span></p><p>For those concerned about climate change, this is an alarming threshold. We don’t know yet what it will mean in the coming decades, but the last time the CO2 level was this high in the atmosphere about two and a half million years ago, the Earth was a much warmer, much different place.</p><p>Those who have been concerned about climate change have been talking about this and some have taken action. One of those people lives here in Michigan.</p><p> Mon, 24 Jun 2013 22:11:20 +0000 Stateside Staff 13214 at http://michiganradio.org Retrofitting a 112-year-old house with solar panels The do-it-yourself snow and ice test http://michiganradio.org/post/do-it-yourself-snow-and-ice-test <p>In the winter... there&rsquo;s a quick and easy way to find out where your house is leaking energy... just by looking at your roof a day or two after a good snow. Greenovation.tv&rsquo;s Matt Grocoff invited me along on what he calls a <a href="http://environmentreport.org/show.php?showID=511">drive-by energy audit</a>.</p><p>Here&#39;s what to look for:</p><ol><li>Icicles are pretty... but they&#39;re a sign that your attic needs more insulation. Heat from your house is escaping and melting the snow.</li><li>If you have ice clogging your gutter, it can cause damage to the gutter... and ice can get underneath your roof shingles and damage your roof.</li><li>You can use a roof rake to clear snow from your roof... but it&#39;s just a short-term fix. A better solution is to check out the non-profit group <a href="http://michigansaves.org/">Michigan Saves</a> to find a qualified contractor, who can come out and perform an energy audit and find your home&#39;s leaks and advise you on how to fix them so you can save energy and money.

That means in a year the home will produce as much energy or more than it uses. <a href="http://environmentreport.org/show.php?showID=492">Lester Graham reports</a>... the owners are at the point where they can reach that goal.</p><p>Matt and Kelly Grocoff bought an old house in a historic neighborhood in Ann Arbor a few years ago. Matt wanted to show that making an older home an energy efficient showcase made more sense than building new.&nbsp; Kelly was just a little skeptical.</p><blockquote><p>“When we first bought the house and Matt was talking about what he wanted to do and what some goals might be, part of me was sort of like yeah, yeah, you know. Matt’s a dreamer. He likes to think big. And it’s really happening.”</p><p>&nbsp;</p></blockquote><p><a href="https://www.energystar.gov/index.cfm?fuseaction=HOME_ENERGY_YARDSTICK.showGetStarted">Find out how to assess your own home's energy efficiency.</a></p><p> Tue, 21 Dec 2010 15:40:50 +0000 Rebecca Williams 662 at http://michiganradio.org Oldest Net-Zero House in America
