Preface: Field investigation of ocean acidification effects in northwest European seas

The pH of the ocean is being lowered by its uptake of anthropogenic atmospheric carbon dioxide (CO2), produced as a result of combustion of fossil fuels and land use changes. This acidification is especially pronounced in the surface ocean, where the loadings of anthropogenic CO2 are greatest because of the direct contact with the atmosphere. […]

Bacteriostatic suppression in Norway lobster (Nephrops norvegicus) exposed to manganese or hypoxia under pressure of ocean acidification

Future ocean acidification (OA) and warming following climate change elicit pervasive stressors to the inhabitants of the sea. Previous experimental exposure to OA for 16 weeks at pH levels predicted for 2100, has shown to result in serious immune suppression of the Norway lobster, Nephrops norvegicus. The lobsters are currently affected by stressors such as […]

New Research on Tree Rings as Indicators of Past Climate

A new study has recently been published that looks at the ecology of bristlecone pine growth at Sheep Mountain, and the tree ring signal those trees produce, at high altitudes in the Southwestern US. This is important because tree rings are an often used proxyindicator for reconstructing past climates. Those who keep track of the…

2014 may be the warmest year on record

In early December I wrote a post called “2014 will not be the warmest year on record, but global warming is still real.” The very first thing I said in that post is that I was going out on a limb. I also discussed whether or not one year mattered, and I discussed the nature…
