Caribbean Water

By Rud Istvan | Climate Etc… | October 19, 2013

The Associated Press ran an alarming news piece on 9/6/13:  Climate Change Threatens Caribbean’s Water Supply

It was picked up and echoed around the world, from Time Magazine’s Space and Science section in the US to CBC Canada to ABC Australia to ZeeNews India. The headline was everywhere, repeated at the Huffington Post as ‘Caribbean water supplies severely threatened by climate change.” The AP story reported on contemporary expert warnings at an August 2013 UN conference in St. Lucia. The lead AP paragraph is quite clear:

“Experts are sounding a new alarm about the effects of climate change for parts of the Caribbean—the depletion of already strained drinking water throughout much of the region.”

Experts like Avril Alexander, Caribbean coordinator of Global Water Partnership:

“When you look at the projected impact of climate change, a lot of the impact is going to be felt through water.”

Experts like Lystra Fletcher-Paul, Caribbean land/water officer for the UN FAO:                    

 “Inaction is not an option. The water resources will not be available.”

Yet another anthropogenic global warming alarm, and just in time for IPCC AR5, whose newly released WG1 chapters 7 and 11 say there is high confidence that dry regions will get drier, wet regions will get wetter, and storms will get stormier. “But there is only low confidence in the magnitude.” These Caribbean experts are much more certain—Caribbean water resources will not be available.

Little in this MSM AP news is what it seems. Paragraph 2 starts out saying rising sea levels could contaminate Caribbean fresh water supplies. What a curious assertion. Less dense fresh water floats on top of salt water no matter the sea level. Excessive groundwater draw-down can cause saltwater intrusion from below. That is already a problem in urbanized Broward County, Florida despite proximity to the Everglades.  And on the Tuvalu atolls in the Pacific, where government owned tourist hotels have strained its very limited groundwater capacity. Tuvalu is another urban development problem, not AGW. It was caused by Tuvalu’s government itself, eager to develop ecotourism (diving) after their new Funafuti runway was built with World Bank financing.

Saltwater intrusion doesn’t apply much to Caribbean island groundwater. The islands are mountainous. Pico Duarte in the DR is 3098m. Pic la Selle in Haiti is 2680m. Jamaica’s Blue Mountain is 2256m. Cuba’s Pico Turquina is 1974m. Antigua’s ‘Boggy Peak’ is 402m. St. Croix’ ‘Mount Eagle’ is 355m.  Barbados is only hilly, with a maximum elevation of ‘just’ 343m. Barbados:

Rising sea levels will not contaminate Caribbean fresh water supplies.

The AP reported that Jason Johnson, head of the Caribbean Water and Wastewater Association, said the real issue is groundwater replenishment.

“Many Caribbean nations rely exclusively on underground water for their needs, a vulnerable source that would be hit hard by climate change effects. That’s the greatest concern. Those weather patterns may change, and there may not necessarily be the means for those water supplies to be replenished at the pace that they have historically been replenished.”

The AP noted some of the islands experienced an unusual dry spell in 2012. That’s weather. But Cedric Van Meerbeck, climatologist with the Caribbean Institute for Meteorology & Hydrology, made the inevitable AGW connection:

“There are a number of indications that the total amount of rainfall in much of the Caribbean would be decreasing by the end of the century.”

Since 2012 was dry, and AR5 WG1 Chapter 7 executive summary says dry will get dryer, perhaps IPCC pronouncements are the indications. But regionally down-scaled GCMs cannot make such predictions on multi-decadal time scales. [1]

Intense rains fully ameliorated the unusual 2012 dry spell early in the usual 2013 Caribbean tropical storm season. AR5 WG1 7.6.2 also says wet will get wetter and storms stormier. That worries Barnard Ettinoffe, President of the Caribbean Water and Sewerage Association:

“Heavy rains mean there’s not enough time for water to soak into the ground as it quickly runs off.”

Climate change causes dry to get drier and wet to get wetter according to AR5 WG1 11.3.2.3.1. It threatens Caribbean island water supply both ways!

What is actually going on was clued in the lead AP paragraph above—depletion of already strained water supplies throughout much of the region.

Much of the region is not correct. The AP story cites a 2012 study from British investment risk firm Maplecroft [2] saying Barbados is most at risk, but Cuba and the Dominican Republic also have high water security risk. On the large island of Hispaniola, the Dominican Republic has 2069m³ of renewable water per capita according the World Bank.[3] Cuba has 3381m³. The UK (another island for comparison sake) has 2311m³ but is not a water risk. The only way Cuba and the Dominican Republic could have a high water security risk rating (when the UK doesn’t) is through some illogic unrelated to water.

Barbados (although verdant, as the above picture proves) does have the least per capita renewable water in the Caribbean, only 284m³. That is because Barbados water consumption has doubled over the past 50 years [4] as its population has grown from ≈232K to ≈280K while its per capita GDP tripled from ≈$4k to ≈$12k. Water has become a major problem, and Barbados doesn’t have the oil wealth to import food (virtual water) or desalinate seawater like Saudi Arabia (86m³). Barbados’ water problem is anthropogenic, but not AGW. It is about unsustainable population growth and economic development on a smallish dryish island–just like on Tuvalu.

Another Caribbean country with current water problems is Antigua/Barbuda, at 590m³. Neither indigenous Caribbean tribes nor Spanish conquistadors settled those islands because of insufficient fresh water. The British did later. The country’s population has almost doubled from ≈54k in 1960 to ≈90k today. That always eventually causes finite resource problems. And now has in naturally dry Antigua/Barbuda.

Climate change does not threaten Caribbean water supplies. Population growth and economic development already do on some of the smaller islands. And they are using climate change to ‘extort’ financial aid (e.g. for desalination) from the usual rich ‘guilty’ AGW culprits.

The UN Framework Convention on Climate Change organized this regional conference (at St. Lucia’s luxurious Bay Gardens Hotel/Resort) for Caribbean environment ministers and politicians. The UN organizer’s locally televised purpose was to give “these less developed country ministers and politicians the information and tools to know what to ask for in the negotiations leading up to the new world agreements of 2015”. That starts at COP19 in Warsaw in November 2013.

It is no coincidence the conference was held on St. Lucia. Its minister presently heads the Alliance of Small Island States (AOSIS).  AOSIS says its 44 member states comprise 30% of developing countries, 20% of UN member states, and 5% of world population. The AOSIS agenda for COP19 is clear from its PR after being disappointed at June 2013 Bonn meetings:

At the closing of the latest round of U.N. climate talks, the Alliance of Small Island States (AOSIS), a group of 44 low-lying and coastal countries that are highly vulnerable to the impacts of climate change, released the following statement:

“After losing two weeks to needless procedural wrangling, it is worth recalling the scale of the challenge we face and the precious little time remaining to meet it… Therefore an international mechanism to address the permanent injury our islands are experiencing [emphasis added] must be established this year at the Warsaw conference.”

Tuvalu is the AOSIS member most aggressively agitating for UN ‘climate change aid’, having experienced saltwater intrusion caused by government tourist hotel development. Hence the AP story’s odd second paragraph, which is unrelated to the Caribbean but right in the AOSIS (Tuvalu) lobbying sweet spot.

Hey mon, its Babylon politricks. (H/T to Bob Marley and Jamaica, a Caribbean island of 2.7 million people enjoying 2473m³ renewable water per capita and fantastic reggae music.)
