Ice Halos over Bavaria

"For suspended water to freeze into an ice fog requires quite cold temperatures, and indeed the air temperature on this day was measured at well below zero. The ice fog reflected light from the Sun setting behind St. Coleman Church."

Taking the temperature of the ocean by measuring the speed of sound waves passing through it

Taking the temperature of the ocean by measuring the speed of sound waves passing through it: A team of researchers from the California Institute of Technology and the Chinese Academy of Sciences has developed a way to detect changes in ocean temperatures by measuring sound waves generated by underwater...

Elevated CO2, increased leaf-level productivity, and water-use efficiency during the early Miocene: Abstract. Rising atmospheric

Elevated CO2, increased leaf-level productivity, and water-use efficiency during the early Miocene: Abstract. Rising atmospheric CO2 is expected to increase global temperatures, plant water-use efficiency, and carbon storage in the terrestrial biosphere. A CO2 fertilization effect on terrestrial vegetation...

The tropical steam-engine: how does El Niño warm the entire globe?: El Niño has a hugely pervasive effect on global temperatures

The tropical steam-engine: how does El Niño warm the entire globe?: El Niño has a hugely pervasive effect on global temperatures - for every degree the tropical Pacific warms, land temperatures warm by 1.5 degrees. How? Because the tropical ocean is a very good heater.
