Textbook: Bicarbonate is formed when carbon dioxide dissolves in water, so its concentration is related to the amount of carbon dioxide in the local environment. As well as low carbon dioxide levels causing electrons to build up and trigger the release of bicarbonate, the study also suggests the possibility that the level of carbon dioxide itself in the local leaf environment could impact on the bicarbonate binding. “This is such an intuitive feedback mechanism at the heart of biology that I think it will go into school textbooks,” said lead author, Professor Bill
Rutherford FRS from the Department of Life Sciences at Imperial.
“Now that we understand this new mechanism in the lab, the next step is todefine when it kicks in out there in the field – not to mention the forest, greenhouse, plant pot, sea, lake and pond.”
Factors that have led to the low price quotes include incentives for work in China and the high number of sunny days typically found in Dubai, but industry analysts have suggested that the lower prices are a signal that prices for solar panels are significantly lower than they have ever been & some have suggested that the drop is likely to continue.

Summary:Professor Grant Bigg, from the University’s Department of Geography: “Many people may associate warmer seas with the pleasant weather conditions they’re used to experiencing while on holiday, but the fact of the matter is that an increase in sea temperatures is having a huge impact on the world’s weather.
“Our study has shown that severe hurricanes, storm surges, melting ice in the Arctic region and changes to El Niño are all being caused by sea temperatures rising across the planet. These are all things that can have a devastating impact on the way we live our lives. Read More:

Iowa is currently the state with the second-largest production of wind-powered electricity (generating 15 MWh) behind only Texas, which generates 36 MWh. In Iowa, that accounts for a leading 31.3 percent of all electricity consumed.
Unique to the project is a promise made by Des Moines-based MidAmerican that
the installation costs of the turbines will not affect consumer energy bills,
nor will the state be asked to pay for them—instead, MidAmerican will be footing
the $3.6 billion cost itself. It is a utility company offering electricity and
natural gas to customers in Nebraska, South Dakota, Illinois and of course, Iowa.
The company has set a goal of getting the state off coal completely and expects
this new project to advance that goal—they project that once the project is fully
operational, and other projects go forward as well, fully 85 percent of the electricity used in Iowa will come from wind powered turbines by 2020.
Harnessing the full potential of science and technology to promote sustainable development requires that more researchers target a significant portion of their efforts on sustainability problems, and that those efforts become more effective in producing knowledge that is truly useful – and used – for achieving sustainability goals.
