Even at pCO2 conditions far above those predicted to occur over the course of the next century, ocean acidification has absolutely no impact on oyster valve gaping behavior...

A 200-Year Precipitation Proxy from Northwest China (26 December 2018)
It would appear that no forcing (including the 40% modern rise in atmospheric CO2) has been of sufficient magnitude to drive long-term precipitation change in this area of China over the past two centuries...

Evolutionary Thermotolerance of a Marine Diatom (21 December 2018)
Current predictions of the impacts of global warming on future primary production are not only off in the magnitude of change that they predict is coming, but in the very sign or direction of that change...

A CO2-induced Stimulation of Red Spruce Forest Growth Since 1989 (20 December 2018)
The number one factor responsible behind a 106% increase in red spruce basal area increment since 1989 is -- you guessed it -- rising concentrations of atmospheric CO2!...

The Positive Response of Seven Phytoplankton Species to Ocean Acidification (19 December 2018)

A Coccolithophore's Response to Ocean Acidification (14 December 2018)
Regardless of pCO2 seawater conditions ranging from glacial to present-day to a predicted future, Ochrosphaera neapolitana is able to regulate its calcifying fluid pH to maintain pH homeostasis at the site of calcification and thus continue calcifying and photosynthesizing at a constant rate...

A Bright Future for U.S. Loblolly Pine Forests (13 December 2018)
A mean projected increase of 30.4% in loblolly pine forest productivity by mid-century is expected for the southeastern United States, courtesy of rising temperatures and rising atmospheric CO2 concentrations...

The Impact of the Urban Heat Island on Temperature in Manchester, UK (12 December 2018)

The Increasing Surface Mass Balance of Two Antarctic Glaciers (6 December 2018)
The Antarctic Peninsula has long been considered a poster-child of the climate alarmist movement, having experienced a warming rate that rivaled those of all other locations on the planet over the second half of the 20th century. Fast forward to the 21st century, however, and the data reveal a reversal of temperature trends (i.e., a cooling), along with evidence of glaciers accumulating mass -- discouraging findings if you are a climate alarmist...
