Super-heatwaves of 55°C to emerge if global warming continues
August 9, 2017 02:19 PM - European Commission, Joint Research Centre (JRC)

Heatwaves amplified by high humidity can reach above 40°C and may occur as often as every two years, leading to serious risks for human health. If global temperatures rise with 4°C, a new super heatwave of 55°C can hit regularly many parts of the world, including Europe.

Climate change may confuse plant dormancy cycles

Perennial plants in the Midwest are well attuned to their surroundings. They hunker down all winter in a dormant state, just waiting for a sign that it’s safe to unfurl their first tender leaves or flower buds. For many plants, the cue is a sustained warming trend, but day length also factors into the dormancy equation.

NASA-NOAA's Suomi NPP Satellite Takes a Double Look at Tropical Storm Franklin
August 9, 2017 12:08 PM - NASA / Goddard Space Flight Center

When NASA-NOAA’s Suomi NPP satellite passed over Tropical Storm Franklin instruments aboard provided a night-time view of the storm’s clouds and measured their temperatures, revealing a strengthening storm.

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the NASA-NOAA Suomi NPP satellite captured infrared images of Franklin on August 8 at 3:58 a.m. EDT (0758 UTC). The Suomi NPP night-time image showed that Franklin’s northwestern edge had not yet reached San Francisco de Campeche or Merida, as the lights of both cities were still visible in the image. The infrared image provided temperatures of Franklin’s cloud tops, where thunderstorms surrounding the low-level center were as cold as 190 Kelvin (minus 117.7 degrees Fahrenheit / minus 83.1 degrees Celsius). NASA research has shown that storms with cloud top temperatures that cold have the ability to generate very heavy rainfall.

NASA's Smartest Satellite Is Gone. Can Private Space Replace It?
August 9, 2017 09:58 AM - Nick Stockton, Wired

Look down on Buenos Aires from the sky, and you can learn a fair bit about the city. It's got a lot of concrete. Also a lot of trees. There's a bright green river delta to the north, which probably explains the ruddy-brown bay to the east. But with the right camera—a hyperspectral one—you can pick up a whole lot more. New colors emerge, hidden hues your eyes and mine aren't wired to see. And these colors reflect even more detail about the scene: the gases coming out of the city, the health of the plants surrounding it, the species of algae coloring the water offshore.

Biochar shows benefits as manure lagoon cover
August 9, 2017 09:48 AM - American Society of Agronomy

Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few.

Can Poor Air Quality Mask Global Warming's Effects?

During the 20th century, the average temperature of the continental United States rose by almost 1 degree Fahrenheit (0.5 degree Celsius) -- everywhere, that is, except in the Southeast.
