Concentrations

As greenhouse gas concentrations continue to rise, infrared radiative cooling by the surface and the atmosphere to space becomes less effective.

We are seeing alarming decline in biodiversity, rising sea levels, coastal erosion, extreme weather conditions and increasing concentrations of greenhouse gases.

“Given current concentrations and ongoing emissions of greenhouse gases, it is likely that by the end of this century ... the world’s oceans will warm and ice melt will continue,” according to the U.N. 2018 climate report.

Scientists studying data from a European Space Agency (ESA) satellite say they have observed a strong reduction in ozone concentrations over the Arctic, creating what they are calling a “mini-hole” in the ozone layer.

The WMO reported more than 90% of the excess energy from increased concentrations of greenhouse gases goes into the ocean.

Atmospheric methane concentrations have more than doubled since the Industrial Revolution because of intensive use of oil, gas and coal, rising demand for beef and dairy products and increased production of food and organic waste.

Surface ocean waters generally have oxygen concentrations close to equilibrium with the Earth's atmosphere.

Scientists found concentrations of the microorganism that were “almost two orders of magnitude greater than any other concentration of phytoplankton ever found on the Earth,” according to Dr. Paula Bontempi, NASA’s Ocean Biology and Biogeochemistry program manager.

Is there a list of permissible chemicals allowed in veterinary vaccines (and their concentrations) or do we have to determine this empirically through safety studies?

Carbon dioxide, methane and nitrous oxide, the main man-made greenhouse gases blamed for global warming, increased to record post-industrial concentrations last year, according to a report by the World Meteorological Organization.
