Climate Change Leads to More Frequent Drought in California

California has experienced more frequent drought years in the last two decades than it has in the past several centuries. That observed uptick is primarily the result of rising temperatures in the region, which have climbed to record highs as a result of climate change, Stanford scientists say.

Scientists Observe Increase in Carbon Dioxide's Greenhouse Effect at Earth's Surface

Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time.

Scientists Quantify how the Greenland Ice Sheet Reacted to Past Warming

A team of scientists lead by Danish geologist Nicolaj Krog Larsen have managed to quantify how the Greenland Ice Sheet reacted to a warm period 8,000-5,000 years ago. Back then temperatures were 2-4 degrees C warmer than present. Their results have just been published in the scientific journal Geology, and are important as we are rapidly closing in on similar temperatures.

Researchers Study High Power Silicon Carbide Semiconductor Switches as Part of MMPSiC Project

The objective of the new cooperation project “MMPSiC” is to significantly enhance the efficiency of power supplies for industrial processes and, hence, to reduce energy consumption and CO2 emission.

Global Warming May Increase Ocean Current Upwelling and Cause Major Changes in Marine Biodiversity

A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will cause major changes in marine biodiversity.

Warming Waters Makes Sardines, Anchovies and Mackerels Migrate North

Sardines, anchovies and mackerels play a crucial role in marine ecosystems, as well as having a high commercial value. However, the warming of waters makes them vanish from their usual seas and migrate north, as confirmed by a pioneering study analysing 57,000 fish censuses from 40 years. The researchers warn that coastal towns dependent on these fishery resources must adapt their economies.

Capturing Excess Carbon Dioxide is a Viable Strategy for Reducing Greenhouse Gases

What if we had the ability to not only reduce greenhouse gas emissions, but also remove excess carbon dioxide from the atmosphere? If we could, where would we store it, and how could it be used in a positive way?

Chemicals Not Controlled by United Nations Treaty Contributing to Ozone Depletion

Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion.

Warmer Climate Affects Natural Disturbances Required for Maintaining Species-Rich Riparian Zones

In her thesis, Lovisa Lind shows that ice and winter floods are important natural disturbances for maintaining species-rich riparian zones along northern watercourses. If the climate becomes warmer this disturbance might be lost. This could potentially lead to a less diverse riparian zone. She defends her thesis at Umeå University on Friday 27 February.

Hockey Stick Graph Remains the Central Icon in Climate Wars

The "Hockey Stick" graph, a simple plot representing temperature over time, led to the center of the larger debate on climate change, and skewed the trajectory of at least one researcher, according to Michael Mann, Distinguished Professor of Meteorology, Penn State.
