Global Tropical Cyclone Activity of the Past Five Thousand Years

Published January 17, 2013

Something has orchestrated the ebbing and flowing of global TC activity over the last 5,000 years, but that something has most certainly not been changes in the atmosphere’s CO2 concentration… Read More

Free-Air CO2-Enrichment May Not Be All It’s Cracked Up to Be (15 Jan 2013)
A new study suggests that the long-used experimental technique may significantly underestimate the magnitude of the aerial fertilization effect of atmospheric CO2 enrichment on plant growth… Read More

Responses of Juvenile Mussels to Experimentally Acidified Seawater (15 Jan 2013)
Can the fragile little creatures successfully cope with it? It would appear from the results of this study that they may well survive – and possibly even thrive – in a CO2-enriched world of the future… Read More

Climate Change in China Over the Past Century (15 Jan 2013)
What’s been happening weatherwise in the world’s most populated country to cause the researchers of this study to conclude that confidence in model projections for this region “is low”?… Read More

Carbon and Nitrogen Cycling in CO2-Enriched Forests (16 Jan 2013)
The two phenomena are tightly-linked and will likely benefit forest growth in a CO2-enriched world of the future through a process the authors of this study refer to as Rhizo-Accelerated Mineralization and Priming… Read More

Iron Released from the Melting of Antarctic Glaciers (16 Jan 2013)
Observations suggest it doubles the productivity of the water column, revealing that “melting glaciers have the potential to increase phytoplankton productivity and thereby CO2 uptake, resulting in a small negative feedback to anthropogenic CO2 emissions”… Read More

Effects of Elevated CO2 on Herbivore Damage to Birch and Aspen Foliage (16 Jan 2013)
According to the authors of this study, “growth under elevated CO2 reduced the distance that herbivore-induced reductions in photosynthesis propagated away from the point of damage in aspen and birch.” As a result, the authors conclude that elevated CO2 “may reduce the impact of herbivory on photosynthesis,” which is a very promising finding… Read More
