Climate Change skeptics? [ot]

No source and once again you are pulling that one outta yur ass as is RILEDUP about the Cod all being gone.

-Pay some $50-100K outta pocket expenses and then cut out that kidney, lung and heart as well based on a diagnoses that is less than 100% certainty.

-Invade a sovereign Nation based on less than 100% certainty that they have and are going to use WMD's.


-Allow a FED Judge authorize a Warrant to have DEA/ATF SWAT invade YOUR home based on less than 100% certainty YOU may have automatic weapons and a large stash of ammo stored in it.

And so on...

Got it.

Are you like a little fish Anita? Did you catch the Sea Bass in Baja?

Managing the remnants of the ocean’s resources is a critical issue worldwide, but evidence for what constitutes a healthy fish population remains controversial. Here, we use historical sources to understand ecosystem trends and establish a biomass estimate for a key marine species prior to the industrialization of fishing. Declining trajectories have been described for predatory fishes and complex coral reef systems globally, but few numerical estimates of past abundance exist. We combined historical research methods and population modeling to estimate the biomass of cod on Canada’s Scotian Shelf in 1852. Mid 19th-century New England fishing logs offer geographically specific daily catch records, describing fleet activity on fishing grounds with negligible incentive to falsify records. Combined with ancillary fishery documents, these logs provide a solid, reliable basis for stock assessment. Based on these data we estimate a biomass for cod of 1.26 x 106 mt in 1852 – compared with less than 5 x 104 mt of total biomass today. In the current policy debate about rebuilding depleted fisheries and restoring marine ecosystems, it is important to recognize that fisheries for key commercial species like cod were far more productive in the past. As we attempt to rebuild these fisheries, our decisions should reflect real and realistic goals for management, not just recently observed catch levels.

Northwest Atlantic cod illustrate the negative synergy of environmental adversity coming atop overfishing. West Greenland stocks (first graph in Fig. 2) were reduced by peak overfishing in the early to mid-1960s. The fall after this peak coincided with the abrupt arrival in 1969–1970 of a pulse of cold, fresh Arctic water (see Fig. 1). Although warmer conditions eventually returned to West Greenland, they were punctuated by further episodes related to circulation changes and Greenland ice-sheet attrition (Belkin et al., 1998; Belkin, 2000) that created conditions off West Greenland periodically too cold for local spawning. Moreover, wind and North Atlantic Oscillation (NAO) related shifts in flow of the Irminger Current resulted in fewer cod being imported from Icelandic waters (Buch, 2000; Buch et al., 2003). After a small terminal spike in fishing between 1988 and 1990 (mainly exploiting a 1984 cohort arriving from Iceland), Atlantic cod virtually disappeared from West Greenland. Several other demersal species had declined steeply as well (Ratz, 1992, 1999). After cod declined, northern shrimp (Pandulus borealis) became more abundant, a trophic-level shift consistent with Pauly et al.’s (1998) description of “fishing down food webs.” An emerging shrimp fishery took the place of cod as Greenland’s economic staple (Hamilton et al., 2000, 2003; Rasmussen and Hamilton, 2001).

The 1990s collapse of Newfoundland’s cod fishery (second, third and a share of the fourth graph in Fig. 2) followed a similar pattern of overfishing compounded by adverse climate, near-disappearance of the dominant species, then a new ecological and economic prominence for crustaceans. Biological analyses point to overfishing, first by international fleets in the postwar years, then after 1977 mainly by Canadian vessels, as the primary cause of the cod collapse (Hutchings and Myers, 1995; Sinclair and Murawski, 1997). Cod stocks eroded to historically low levels in the mid-1970s, and made no more than a partial recovery before the Canadian effort ramped up. Climate added to the resumed fisheries pressure in the late 1980s and early 1990s, when unusually cold, icy waters off east, north and northwest Newfoundland (Drinkwater, 2002) reflected some of the same NAO/circulation anomalies that beset the final years of Greenland’s cod fishery. Cod abundance, size-at-age and catches all began falling after the mid-1980s peak in catches that Palmer and Sinclair’s (1997) northwest Newfoundland fishermen described as their “glory years.”

Ah, who the fk ever mentioned anything about large scaled fishing???

The COD are NOT gone. Nor has MAN fished them ALL to extinction.
