Good stewards leave something better than they found it. But will Florida be a place where your children or your grandchildren even want to live? The heat is on, the seas are rising, and warming waters may be exacerbating Red Tides and toxic blue-green algae blooms. Florida is deeply affected by climate change, and the effects are accelerating. You can literally feel them. If we don’t cut carbon emissions, the Sunshine State will become more purgatory than paradise. Is that what we want for our kids and their kids? Will we let that be our legacy?

THE HEAT.

Think it’s hot now? Just wait. A new study by the Union of Concerned Scientists predicts that by mid-century it may be unsafe to work outside in the Tampa Bay area for a third of the year. Unless we stem climate change, we may face four months each year with a heat index of 105 degrees or more — that’s compared with four such days a year right now.

Sea level is rising, and it’s doing so faster. Even based on a conservative sea-level rise scenario, Florida could face costs of $76 billion to build sea walls by 2040 to mitigate the effects of climate change, according to a recent report from Resilient Analytics and the Center for Climate Integrity. No one believes that sea walls are actually a cure-all, but it’s a grim way to put a price on the problem. Worse, the Tampa Bay region is particularly susceptible to sea level rise. In reality, residents will have to retreat from the water in many places, abandoning some expensive waterfront real estate, and then letting nature — mangroves, for example — provide buffers from the rising waters.

Warming waters and run-off of polluting fertilizer provide ideal conditions for toxic algae blooms to flourish as well as amplifying the effects of naturally occurring Red Tides.

WHAT TO DO?

It will take a huge commitment of time, effort and money to stem this problem. But it must be addressed — now. One good way to raise money while cutting pollution is a fair carbon tax. It would literally put a price on pollution and make polluters pay instead of giving them a free ride. It’s a smart way to let the free market, not the government, pick winners and losers.
