2012 Drought more expensive than Hurricane Sandy

You thought Hurricane Sandy was bad? You were right, but economically, the ongoing drought is worse economically. But we already know a much brighter path.

Weather Underground founder Dr. Jeff Masters wrote 16 November 2012, Lessons from 2012: Droughts, not Hurricanes, are the Greater Danger,

Sandy’s damages of perhaps $50 billion will likely be overshadowed by the huge costs of the great drought of 2012.

By Dr. Masters’ estimate, the 2012 drought will cost more than half again as much as Hurricane Sandy.

Also notice Hurricane Katrina still at the top of that table, with almost three times the economic damage and far more deaths than Hurricane Sandy. We could have gotten the message back in 2005, but hey, those were only poor southern people, so who, in for example New York City, really cared? Yes, I know many of us did and many of you actively helped, but I’m sure you see my point that when greater New York gets the storm, suddenly the country pays attention and a lot more people want to find out how to keep that from happening again.

What’s that drought look like for us here in Georgia at the moment, according to U.S. Drought Monitor?

Savannah and Jacksonville most vulnerable to rising sea level

Savannah and Jacksonville are among the east coast cities most vulnerable to rising sea levels due to climate change, a study finds. Savannah, Georgia’s main seaport, with storm surges, hurricanes, and waves on top: what will that look like?

Suzanne Goldenberg wrote for the Guardian today, US coastal cities in danger as sea levels rise faster than expected, study warns: Satellite measurements show flooding from storms like Sandy will put low-lying population centres at risk sooner than projected,

A study published last March by Climate Central found sea-level rise due to global warming had already doubled the risk of extreme flood events — so-called once in a century floods — for dozens of locations up and down the Atlantic and Pacific coasts.

It singled out the California cities of Los Angeles and San Diego on the Pacific coast and Jacksonville, Florida, and Savannah, Georgia, on the Atlantic, as the most vulnerable to historic flooding due to sea-level rise.

Sandy, which produced a 9ft storm surge at Battery Park in New York City, produced one example of the dangerous combination of storm surges and rising sea level. In New York, each additional foot of water puts up to 100,000 additional people at risk, according to a map published with the study.

That study projected 6 inches rise at Fort Pulaski by 2030 (minimum 3 inches) and 13 inches by 2050 (maximum 24 inches). But projections have gotten worse since then:

Sea level changes measured and projected The latest research, published on Wednesday in Environmental Research Letters, found global sea-levels rising at a rate of 3.2mm a year, compared to the best estimates by the IPCC of 2mm a year, or 60% faster.

So that would be more like 9 inches by 2030 and 20 inches by 2050.

Add to a higher base sea level bigger storms like Hurricane Sandy, and Savannah and Jacksonville have a problem. Sure, Savannah is Continue reading →

Longleaf Flood Prevention and Carbon Sequestration

dscn1384_candle_dead_leaves Instead of planting fast-growing slash or loblolly pines just to burn up in a biomass plant, how about plant the south’s iconic longleaf pine trees to capture and hold carbon from the atmosphere?
“Longleaf should be the centerpiece of land-based carbon sequestration efforts in the Southeast,” the report states, urging that national policymakers make the ecosystem as high a priority as the Everglades or Chesapeake Bay.
The report is Restoring the Longleaf Pine: Preparing the Southeast for Global Warming, Published December 10, 2009 by the National Wildlife Federation and two southeast forest conservation groups, America’s Longleaf, and The Longleaf Alliance.

People rightly worry about deforestation in the Amazon basin of Brazil, but forget or never knew that we already did that right here in the southeast: Continue reading →
