Heat Wave Intensifies Siberian Wildfires
2013-08-08 08:21:58

NASA The summer of 2012 was the most severe wildfire season Russia had faced in a decade. 2013 might be headed in the same direction after an unusual heat wave brought a surge of fire activity in northern Siberia in July. A persistent high-pressure weather pattern in the Russian Arctic -- a blocking high -- contributed to the heat wave, which saw temperatures reach 32 degrees Celsius (90 degrees Fahrenheit) in the northern city of Norilsk. For comparison, daily July highs in Norilsk...

Climate Change May Be Fueling Devastating Wildfires
2013-08-02 04:55:42

redOrbit Staff & Wire Reports - Your Universe Online The larger, more destructive wildfires devastating some regions of the western US could be fueled by climate change, according to new research appearing in the Journal of Applied Meteorology and Climatology. These erratic fires are more difficult to contain, as well as more dangerous to people living in the area and likely to cause catastrophic damage, lead author and Michigan State University assistant professor of geography...

Wildfires To Increase In Severity
2013-07-10 09:12:59

redOrbit Staff & Wire Reports - Your Universe Online Wildfires like the ones that have ravaged Arizona and Nevada this summer are expected to become far more severe over the next several decades, say researchers from the University of Alberta Faculty of Agricultural, Life and Environmental Sciences (ALES) in a new study. In fact, lead author Dr. Mike Flannigan and his colleagues report that the severity of wildfires will increase three-fold by the end of the century, and that as...

Global climate change Will Induce Large Changes To The Plant Communities On Earth
2013-07-02 14:44:09

Aarhus University The forest we are used to looking at is not at all in equilibrium. Since the Ice Age, a number of plants have been 'missing' in Northern Europe, i.e. species that have not yet arrived. The same applies in many other parts of the world. Similarly, there is evidence that -- even today -- it often takes a very long time before plants follow when glaciers retreat, or the climate changes. In future, such disequilibrium will become the norm in the plant communities on Earth....

Climate Change Threatens Survival Of Forests On Drier, Low-elevation Sites
2013-06-28 10:10:53

Oregon State University Predicted increases in temperature and drought in the coming century may make it more difficult for conifers such as ponderosa pine to regenerate after major forest fires on dry, low-elevation sites, in some cases leading to conversion of forests to grass or shrub lands, a report suggests. Researchers from Oregon State University concluded that moisture stress is a key limitation for conifer regeneration following stand-replacing wildfire, which will likely...

Herbal Earth Revealed By NASA/NOAA Project: Suomi NPP
2013-06-22 05:28:49

redOrbit Staff & Wire Reports - Your Universe Online New high-resolution images released earlier this week by NASA provide a bird’s-eye view of the areas of Earth where there is lush vegetation, as well as arid regions where the landscape is barren. The photos, which were crafted using a year’s worth of data collected by a joint NASA/National Oceanic and Atmospheric Administration (NOAA) project known as the Suomi NPP (Polar-orbiting Partnership), were revealed to the public by...

A recent study in the Journal of Forestry now offers managers a tool to help them identify regions exposed to multiple forest threats. The tool uses a novel 15-mile radius neighborhood analysis to highlight locations where threats are more concentrated relative to other areas, and identifies where multiple threats may intersect. It is a technique that may have never been used before to describe forest threats, according to the researchers. "Policymakers and managers often rely on maps...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
