Study finds increased CO2 enhancing plankton growth; opposite of expected

Green Car Congress

The results show both the power of long-term time-series of ocean observations for deciphering how marine microbial communities are responding to climate change and offer evidence that the ocean garden is changing. The CPR survey was launched by British marine biologist Sir Alister Hardy in the early 1930s.

Worlds Coral Reefs Began Decline At 320 ppm Atmospheric CO2

Green Car Congress

Veron of the Center for Marine Studies, University of Queensland. The Earth’s atmospheric concentrations of CO2 reached 320 ppm in the mid-1960s, and 360ppm in the mid-1990s. 360ppm is the level at which reefs “ cease to be viable in the long term ,” according to coral reef specialist Professor John E.N. Jack Rosebro.

This Startup Is Building the Internet of Underwater Things

Cars That Think

Water covers 72 percent of the Earth’s surface, its volumes host 80 percent of biodiversity and play a pivotal role in global phenomena, such as climate change. Pioneering underwater network technology There are a few marine research stations scattered around the globe (like needles in algal stacks).

Study using paleoclimate data suggests climate sensitivity to CO2 doubling may be less severe than projected

Green Car Congress

The team combined extensive sea and land surface temperature reconstructions from the Last Glacial Maximum (LGM) with a climate model of intermediate. complexity to estimate the equilibrium climate sensitivity for a doubling of atmospheric carbon dioxide concentrations (ECS 2xC ) from. preindustrial times. However, we cannot exclude.

Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

The researchers concluded that models of climate change may be underestimating how much water is likely to run off the land and back into the sea as atmospheric chemistry changes. Either way, water resource managers need more accurate runoff estimates to plan better for the changes. Benjamin Felzer, Lehigh University.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

The researchers determined the global warming potential, expressed in carbon dioxide equivalents (t e CO 2 ), for seven components of urban inventories: electricity, heating and industrial fuels, industrial processes, ground transportation, aviation, marine, and waste. t e CO2/cap.)

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

As has been emphasized in several previous studies, a continued cooling response does not negate the necessity for reductions in CO 2 emissions, which are crucial to limiting the global climate impact of the sector since the warming effect of CO2 is long-lived. —Lund et al.
