Forest fires usually spread out of control very quickly. Fires that produce a lot of smoke are particularly challenging for the emergency services, because the source of the fire is then especially hard to find. A new radiometric sensor can pinpoint the heart of the flames, even when visibility is limited. The number and scale of forest fires has increased dramatically in recent decades. Who can forget last summer's television images of blazing infernos devouring miles and miles of forest in...

New research indicates that the speed of early forest clearance following human colonisation of the South Island of New Zealand was much faster and more intense than previously thought. Charcoal recovered from lake-bed sediment cores show that just a few large fires within 200 years of initial colonization destroyed much of the South Island's lowland forest. Grasslands and shrubland replaced the burnt forest and smaller fires prevented forests from returning. The findings - by an...

Climate forecasts for the region predict an advance of the desert about 300 kilometers to the north The fire disaster in the Carmel Mountains near Haifa is a typical example of climate change effect and a taste of the future, says Dr. Guy Pe'er, one of the authors of Israel's first report to the UN on climate change. Ten years ago, Dr. Pe'er and other Israeli scientists collated knowledge about the effects of climate change for Israel. They warned already in the year 2000 of expected climatic...

Ecological disturbances are not necessarily a bad thing "“ deliberate disturbances can actually be used to preserve or even increase biodiversity in a nature reserve. The outcome depends on countless different factors, but many mistakes are made by those working with ecological disturbances and biodiversity, claims a researcher from the University of Gothenburg (Sweden). "Nobody knows exactly what biodiversity is, and so different researchers test different measures of it and can draw...

Ask the Eucalyptus connoisseurs Koalas may be the pickiest marsupials around: They evolved to feed almost exclusively on the leaves of Eucalyptus trees, and they are highly selective when it comes to which species and even which individual trees they visit. When the furry leaf-eater settles on a particular tree, it relies on a number of factors, including taste, to make its selection. In a study published in the November issue of Ecology, a journal of the Ecological Society of America (ESA),...

Pyrocumulonimbus is the fire-breathing dragon of clouds. A cumulonimbus without the "pyre" part is imposing enough -- a massive, anvil-shaped tower of power reaching five miles (8 km) high, hurling thunderbolts, wind and rain. Add smoke and fire to the mix and you have pyrocumulonimbus, an explosive storm cloud actually created by the smoke and heat from fire, and which can ravage tens of thousands of acres. And in the process, "pyroCb" storms funnel their smoke like a chimney into Earth's...

If your summer travels have taken you across the Rocky Mountains, you've probably seen large swaths of reddish trees dotting otherwise green forests. While it may look like autumn has come early to the mountains, evergreen trees don't change color with the seasons. The red trees are dying, the result of attacks by mountain pine beetles. Mountain pine beetles are native to western forests, and they have evolved with the trees they infest, such as lodgepole pine and whitebark pine trees....
