Splitting Hairs with a Hatchet: Climate Model Not Up to Task of Determining Real-World Tropospheric Temperature Trend: For some time, now, two groups of scientists have carefully massaged the same set of satellite-derived proto-temperature data in an attempt to determine how earth's near-surface air temperature and that of the atmosphere above may have varied over the past quarter-century.  Their results differ ever so slightly, yet ever so significantly, for the economic and political consequences of who is the more correct are enormous.  Hence, we here review the most recent development in this high-stakes field of atmospheric science.

Calcification in Coral Reefs: Climate alarmists say it should be declining.  Real-world surveys say ...

Greening of the Earth: As the air's CO2 content rises, earth's plants assimilate ever more of the magnificent molecule and respond in a host of marvelous ways that promote vegetative productivity, which is the fundamental activity that makes possible the existence of nearly all forms of life on the planet.

Six Decades of Sea-Level Extremes in the Northern Adriatic: With locally rising sea levels and "unprecedented" global warming that is supposed to promote storminess, extreme surges of the Northern Adriatic at Trieste must be becoming monstrous.

Moisture Regimes of the Northern Prairies of North America: How do they vary?  Let us count the ways!

Effects of Elevated CO2 on Canadian Thistle: Atmospheric CO2 enrichment commonly boosts photosynthetic rates and biomass production in agricultural crops.  So how do weeds fare?

The Impacts of Elevated CO2 and Soil Nutrient Status on Phenological Characteristics of Black Cottonwood Seedlings: Elevated CO2 typically enables plants to better withstand high temperatures that may harm their tissues.  Can it do anything to protect them against dangerously low temperatures?  A study from Iceland provides some answers.

Elevated CO2 Impacts Bulb Size in Hippeastrum: Bulb production is an economically important facet of horticultural science that is sometimes overlooked in CO2 enrichment experiments.  In this paper, however, the authors investigate the impact of elevated CO2 on the growth of two different sizes of bulbs that produce highly-prized flowers.
