Melting Ice Caps

The ice sheets on Greenland and Antarctica are melting, sea levels are rising, and the rate of ice loss is increasing.  These are the conclusions a new peer-reviewed report published in the journal Science came to.  The study, authored by 47 experts from 26 institutes, used satellite images to show that the ice sheet melting has contributed to an 11 mm (0.4 in) rise in sea levels.  The Greenland ice sheets contributed 2/3 to this rise while Antarctica contributed the remaining 1/3.  Also startling were the comments on the Pine Island Glacier, an iceberg the size of New York City that is set to calve off in the upcoming months.  While most of this information is probably not news to you, it does offer scientific proof that the planet is warming.  We must act now.  Please inform yourselves about solutions to climate change – whether through cap-and-trade or a carbon tax – and pressure your elected officials to enact policy measures.  The only way to slow the rate of warming is to reduce our emissions through every means possible.  Use less energy by making energy-efficient upgrades to your house.  Write a letter to your representatives to end subsidies for fossil fuels so renewable technologies can compete on a level field.  Or simply turn off electronics when they are not in use.  Climate change is a problem that touches all areas of modern society – it is a national security issue, an economic issue, a development issue, and a humanitarian issue.  And as this study proves it is getting worse.  The paradox is that by the time we see changes that affect us, it may be too late to stop it.
