Temperature Rise Could Spell Disaster For British Wildlife

[Leon Roskilly]

Didn't know you hated me so much Leon as to expect me to look through all your first link to answer my few questions in post 13. Do me a favour and find the answers and link me to them direct. Thanks awfully.

 

That'll make me head hurt!

Gee, thanks for the info sharkbyte, it's obvious to me that the likes of hillary benn is ignoring the science then as he must have missed this bit as he recons without the likes of him, we might, could be, possibly, maybe all doomed:

 

Iglesias-Rodriguez et al (2008) confirmed Riebesell findings experimentally, concluding that coccolithophores, which account for a third of all marine calcium carbonate production, flourish and calcify much better at higher levels of CO2:

 

Here, we present laboratory evidence that calcification and net primary production in the coccolithophore species Emiliania huxleyi are significantly increased by high CO2 partial pressures. Field evidence from the deep ocean is consistent with these laboratory conclusions, indicating that over the past 220 years there has been a 40% increase in average coccolith mass. Our findings show that coccolithophores are already responding and will probably continue to respond to rising atmospheric CO2 partial pressures, which has important implications for biogeochemical modeling of future oceans and climate.

 

Richardson and Gibbons (2008):

 

…no observed declines in the abundance of calcifiers with lowering pH have yet been reported…the role of pH in structuring zooplankton communities in the North Sea and further afield at present is tenuous.

 

Vogt et al (2008), experimenting with atmospheric concentrations up to three times current levels,

 

…the ecosystem composition, bacterial and phytoplankton abundances and productivity, grazing rates and total grazer abundance and reproduction were not significantly affected by CO2 induced effects.

 

Gutowska (2008) subjected cuttlefish larvae to CO2 concentrations of 6000 ppm (sixteen times current CO2 concentration), at pH 7.1. Results:

 

No differences in soft tissue growth performance were measured between cuttlefish incubated at ~4000 and ~6000 ppm CO2 and controls…Standard metabolic rates of cuttlefish exposed acutely to ~6000 ppm CO2 showed no significant increase or decrease over time…there were no significant differences between the mantle lengths of control cuttlefish and those incubated at 6000 ppm CO2…Interestingly, in the ~6000 ppm CO2 growth trial, the CO2 incubated animals incorporated significantly more CaCO3 [calcium carbonate] into their cuttlebones than did the control group…Functional control of the cuttlebones (i.e. buoyancy regulation) did not appear to be negatively affected by low pH conditions.

 

snigger. (well i think it's funny.)

In the old days, Barry, people used to make a press and print their own money. It was just as dodgy as the modern day equivalent, but it carried a jail sentance if you were caught.

Yes, but they do nice pictures

Many thanks for the link Leon, this one shows it's back to what i have intimated, might be, could be, possibly, can't confirm, etc, etc.

 

The researchers caution, however, that the findings—and acidification's overall impact—may be more complex than it appears. For example, Cohen says that available food and nutrients such as nitrates, phosphates and iron may help dictate how some organisms respond to carbon dioxide.

 

"We know that nutrients can be very important," she says. "We have found that corals for example, that have plenty of food and nutrients can be less sensitive" to CO2. "In this study, the organisms were well fed and we didn't constrain the nutrient levels.

 

"I wouldn't make any predictions based on these results. What these results indicate to us is that the organism response to elevated CO2 levels is complex and we now need to go back and study each organism in detail."

This one of yours, Quote:

 

Coral bleaching and increasing levels of CO2, which is changing the acidity of the ocean, threaten the sustainability of the world's coral reefs and the fisheries they support.

 

and yet another of your links say:

 

"We know that nutrients can be very important," she says. "We have found that corals for example, that have plenty of food and nutrients can be less sensitive" to CO2. "In this study, the organisms were well fed and we didn't constrain the nutrient levels.

 

and Sharkbytes link says:

 

…the ecosystem composition, bacterial and phytoplankton abundances and productivity, grazing rates and total grazer abundance and reproduction were not significantly affected by CO2 induced effects.

 

What i am saying Leon is there is no strong evidence to support Hillary benns warnings of doom and gloom and so the sceptics are looked upon as the loonies who don't 'understand'.
