Rising carbon dioxide levels in oceans adversely change the behavior of fish through generations, raising the possibility that marine species may never fully adapt to their changed environment, research has found.
The study, published in Nature Climate Change, found that elevated CO2 levels affected fish regardless of whether their parents had also experienced the same environment.

If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs.
The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.

Using satellite observations and a large suite of climate models, Lawrence Livermore scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated.
"This underestimation is a result of poor sampling prior to the last decade and limitations of the analysis methods that conservatively estimated temperature changes in data-€Âsparse regions," said LLNL oceanographer Paul Durack, lead author of a paper appearing in the October 5 issue of the journal Nature Climate Change.

The cold waters of Earth's deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years. Scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably. Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself.

Reports show that traditional breeding techniques are years ahead of GM technologies in developing crops to withstand drought and poor soils, writes Lawrence Woodward. Yet GM advocates are sticking rigidly to their script even as the evidence mounds against them.
Since its launch in 2010, the Improved Maize for African Soils Project (IMAS) has developed 21 conventionally bred varieties which have increased yield by up to 1 tonne per hectare.

Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, according to the results of a new study. The paper shows how pollution, known as aerosols, can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future climate change.
