• World Heritage Sites Threatened by Rising Sea Levels

    In the Mediterranean region, there are numerous UNESCO World Heritage Sites in low-lying coastal areas. These include, for example, the Venetian Lagoon, the Old City of Dubrovnik and the ruins of Carthage. In the course of the 21st century, these sites will increasingly be at risk by storm surges and increasing coastal erosion due to sea-level rise. This is the conclusion of one of the first large-scale studies, carried out by doctoral researcher Lena Reimann from the Department of Geography at Kiel University (CAU), together with Professor Athanasios Vafeidis and international partners. The team published their results in the current issue (Tuesday 16 October) of the renowned journal Nature Communications.

  • UNH Researchers Say Winter Ticks Killing Moose at Alarming Rate

    As winter in New England seems to get warmer, fall lingers longer and spring comes into bloom earlier, areas like northern New Hampshire and western Maine are seeing an unusual continued increase in winter ticks which are endangering the moose population. Researchers at the University of New Hampshire have found that the swell of infestations of this parasite, which attaches itself to moose during the fall and feeds throughout the winter, is the primary cause of an unprecedented 70 percent death rate of calves over a three-year period.

  • ANTARCTIC ICE SHELF ‘SINGS’ AS WINDS WHIP ACROSS ITS SURFACE

    Winds blowing across snow dunes on Antarctica’s Ross Ice Shelf cause the massive ice slab’s surface to vibrate, producing a near-constant set of seismic “tones” scientists could potentially use to monitor changes in the ice shelf from afar, according to new research.

  • Forest Carbon Stocks Have Been Overestimated for 50 Years

    It may be a small correction, but it is far from negligible as far as forest ecologists and carbon cycle specialists are concerned. The error lay in a formula established almost 50 years ago (in 1971) for calculating basic wood density. Given that basic density is used to assess the amount of carbon stored in a tree, the fact that the formula had to be corrected meant that forest carbon stocks may have been overestimated by 4 to 5%. "This new formula should enable us to determine more accurately the role of forests in the carbon cycle and the impact of deforestation on climate change" , says Ghislain Vieilledent, an ecologist with CIRAD who was the corresponding author of the work published in the journal American Journal of Botany on 16 October.

  • Can Forests Save Us From Climate Change?

    If you think that sustainable forest management can be a major contributor to mitigating climate change, then you had better not hold your breath. At least not according to the findings in a recent study published in Nature by an international team of scientists led by Vrije University Amsterdam. The team included postdoc Sylvestre Njakou Djomo from the Department of Agroecology at Aarhus University in Denmark.

  • How Do Two Types of Flash Drought Evolve across China?

    Flash drought is a rapidly intensifying water deficit process accompanied by high temperatures in a short period of time. Recently, heat extremes have become more frequent in a warming climate, and substantially increased the occurrence of flash drought, which has severely threatened crop yields and water supply.

  • Climate Change Predictions Could be "Inaccurate"

    Climatologists may be unable to accurately predict regional climate change over the North Atlantic because computer model simulations have failed to accurately include  air pressure changes that have taken place in the Greenland region over the last three decades.
