Robert Redford, CNN:
I believe climate change is the defining environmental issue of our time. It’s hurting our people — around the world — and it’s time to stand up and say we’ve had enough. Enough of rising seas and widening deserts that threaten our homes and our crops. Enough of withering drought and blistering heat that mean more malnutrition and disease. Enough of raging floods, wildfires and storms that threaten people everywhere with one disaster after another.
We’ve got a real chance in Paris to come together and do something about it. But getting it done, and doing it right, will require a powerful public outcry. It’s happening. It’s building.
We know what’s driving the problem, and we know what to do about it. When we burn coal, oil and natural gas, we choke our atmosphere with the dangerous carbon pollution that’s driven global temperatures up about 1.5 degrees Fahrenheit in a little more than a century.
That might not sound like much, but it’s already melted about third of the Arctic sea ice in recent decades. That’s a global change that has global impacts on temperatures, ocean currents and salinity levels. Meanwhile, this carbon pollution has raised the acidity levels of the world’s oceans, threatening shellfish and the coral reefs that support foundational life at sea.
