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.

Climate Change Causes Infectious Diseases to Appear in New Places and New Hosts

The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln.

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.

NOAA's GOES-East Satellite Reveals Colder Temperatures in Cloud Tops

Some of the coldest air of the 2014-2015 winter season was settling over the eastern two-thirds of the U.S. on February 13, 2015. That Arctic air mass brought wind chills from below zero to the single numbers from the Midwest to the Mid-Atlantic. Despite the cold on the surface, infrared NASA satellite imagery revealed even colder temperatures in cloud tops associated with the air mass.

New Study Offers Roadmap for Developing Ocean-Scale Solutions to Address Plastic Marine Pollution

Ocean currents have been carrying floating debris into all five of the world's major oceanic gyres for decades. The rotating currents of these so-called "garbage patches" create vortexes of trash, much of it plastic. However, exactly how much plastic is making its way into the world's oceans and from where it originates has been a mystery -- until now.

Experts Share Findings on Role of Microbes in Ocean Ecosystems at AAAS Symposium

Microbes in the ocean take up massive amounts of carbon dioxide, contributing to the global carbon cycle and affecting climate change. These microbes are abundant, diverse and critical to the health of ecosystems, but they are very hard to study. Innovations in sequencing technologies and techniques are allowing scientists to break open the so-called 'black box' of ocean microbes and revolutionizing science in the ocean.

Novel Concentrating Photovoltaic/Concentrating Solar Power Hybrid System Utilizes Waste Dissipated Heat

In concentrating photovoltaic (CPV) systems only a small part of the incident solar energy can be converted into electricity and the majority of the incident energy is dissipated as waste heat. Although the waste heat could be utilized in conventional CPV/thermal systems, the applications are seriously limited due to the low temperature accompanying the waste heat.
