Countless of times it has been said, and many are still verbalizing it: the only thing constant in this world is change. Truly, life is a permanent change – in good ways and bad, depending on how one looks at it. Some changes can be so hard to deal with; why can’t it be as simple as a grasshopper changing its’ skin? Like changing a day-to-day clothes… no attachments, less emotions.

CO2-Enhanced Nitrogen Fixation to Match CO2-Enhanced Oceanic Productivity: Atmospheric CO2 enrichment does it all in the world’s seas.
In an enlightening review paper published in Photosynthesis Research, Kranz et al. (2011) note that “marine phytoplankton are responsible for almost half of all photosynthetic carbon fixation on earth and play a vital role in altering the CO2 exchange between ocean and atmosphere,” citing Maier-Reimer et al. (1996) and Gruber (2004). However, they note that lack of nitrates often limits phytoplanktonic growth, and that diazotrophic cyanobacteria that fix nitrogen, such as Trichodesmium species, thus play “a crucial role in many marine ecosystems by providing a new source of biologically available nitrogen.” And they go on to describe how atmospheric CO2enrichment helps to enhance both halves of this important two-pronged phenomenon.
First of all, the three researchers – all from the Alfred Wegener Institute for Polar and Marine Research located in Bremerhaven, Germany – report that “four recent studies tested the effect of different CO2 concentrations on the growth, biomass production and elemental composition of Trichodesmium (Barcelos e Ramos et al., 2007; Hutchins et al., 2007; Kranz et al., 2009; Levitan et al., 2007),” and they say that these studies “concordantly demonstrated higher growth and/or production rates under elevated pCO2, with a magnitude exceeding those CO2 effects previously seen in other marine phytoplankton.” Continue reading
Dr Steve Salisbury, from the University of Queensland, is fighting to protect the prints, he says they’re under threat from the gas development. The energy company Woodside started work at the site this week.
But Dr Salisbury says the Federal Government should deny the project final approval, until a full assessment of his findings. He spoke to David Weber….(continued)
Climate Change: There are no laws that say that the global warming alarmists can’t feel strongly about their beliefs. There are, however, ethical lines. And they keep crossing them.
The history of the Great Global Warming Scare is filled with exaggerations, deceit, unnecessary hype and cover-up.
It’s all OK, say the alarmists, because they are concerned with the greater good, and if they have to cheat a bit, well, then the ends justify their means.
This attitude was evident in the climate-gate e-mails.
Warmist McArdle: “ethics aside, what Gleick did is insane for someone in his position–so crazy that I confess to wondering whether he doesn’t have some sort of underlying medical condition that requires urgent treatment”
23 Feb 2012 – Aus shares shed 0.5%. Shares in Fairfax Media Limited (ASX:FXJ) dip after posting a 44 per cent fall in its first half net profit.
Kidding, surely...
Clouds around the world may be falling in response to rising global temperatures and having a cooling effect on global warming, according to analysis of satellite data by Auckland University scientists. (Via Bolta)
These guys have been around sheep too long I think. University scientists?
A cooling effect on global warming? Have you ever heard anything so ridiculous? This crowd ought to spend a bit more time outside and in the environment, instead of hiding around climate models, trying to keep warm and out of the rain and snow. Especially when coming from the land of the ‘long white cloud’.
