As soon as they start life, it's all about survival for juvenile young fish. They must learn to catch prey and to escape enemies. Additionally, at this stage of their lives they are highly sensitive to environmental factors such as temperature, oxygen and the pH of the water. Exactly these factors are currently changing on a global scale: temperature is rising, the oxygen content of the ocean is decreasing and more and more carbon dioxide (CO2) from the atmosphere dissolves in the seawater, where it forms carbonic acid and lowers the pH level. But not only directly, also indirectly elevated CO2 affects the survival of fish larvae, because it can change their food supply.

Intensifying Tropical Storm Jelawat Evaluated by NASA's GPM Satellite
The Global Precipitation Measurement mission or GPM core observatory satellite flew almost directly above large intensifying tropical storm Jelawat and found strong storms generating very heavy rainfall,
GPM passed over the Northwestern Pacific Ocean and captured data on Jelawat on March 28, 2018 at 1:10 a.m. EDT (0510 UTC).
Just One High-Fat Meal Sets the Perfect Stage for Heart Disease
A single high-fat milkshake, with a fat and calorie content similar to some enticing restaurant fare, can quickly transform our healthy red blood cells into small, spiky cells that wreak havoc inside our blood vessels and help set the perfect stage for cardiovascular disease, scientists report.
The Arctic Sea-Ice Loss and Winter Temperatures in Eurasia
The Arctic warming and the decline of the polar sea ice, do these phenomena have a connection to the cooling trends of winter in the Eurasia?
Rapid Emissions Reductions Would Keep CO2 Removal and Costs in Check
Rapid greenhouse-gas emissions reductions are needed if governments want to keep in check both the costs of the transition towards climate stabilization and the amount of removing already emitted CO2 from the atmosphere. To this end, emissions in 2030 would need to be at least 20 percent below what countries have pledged under the Paris climate agreement, a new study finds – an insight that is directly relevant for the global stock-take scheduled for the UN climate summit in Poland later this year. Removing CO2 from the atmosphere through technical methods including carbon capture and underground storage (CCS) or increased use of plants to suck up CO2 comes with a number of risks and uncertainties, and hence the interest of limiting them.
Course Grains Better Than Rice For Health, Environment
Shifting away from white, polished rice to a diet that includes more wheat and coarse grains can improve how Indians deal with micronutrient deficiencies, and reduce greenhouse gas (GhG) emissions associated with paddy cultivation, says a new study.
