OSLO, Sept 2 (Reuters) – Polar bear DNA has been isolated
for the first time from footprints left in the snow on an Arctic
island, a breakthrough that could help scientists better protect
rare and endangered wild animals, experts said on Tuesday.
Scientists often spend days tracking rare animals such as
snow leopards or orangutans for samples of DNA, for instance
from hair or faeces, to understand their movements, monitor
their populations and propose ways to protect them.
OSLO, (Reuters) – Climate change is aiding shipping, fisheries and tourism in the Arctic but the economic gains fall short of a “cold rush” for an icy region where temperatures are rising twice as fast as the world average.
A first cruise ship will travel the icy Northwest Passage north of Canada in 2016, Iceland has unilaterally set itself mackerel quotas as stocks shift north and Greenland is experimenting with crops such as tomatoes.
OSLO, Aug 27 (Reuters) – New roads long enough to girdle the
Earth 600 times are expected to be built by 2050 and better
planning is needed to protect the environment while also raising
food production, a study showed on Wednesday.
The study in the journal Nature showed that roads can aid
farmers, especially in developing nations where food production
is held back by a lack of access to markets or to fertilisers
and other technologies.
OSLO, Aug 25 (Reuters) – Small island states facing a
“frightening” rise in sea levels will seek investments in
everything fron solar energy to fisheries to boost their
economies at a U.N. summit next week.
Leaders will meet in Samoa in the Pacific from Sept. 1-4 to
drum up partnerships with companies, development banks and
donors on projects that bring in dollars and jobs while
protecting oceans and environments, organisers said.
OSLO,(Reuters) – The Atlantic Ocean has masked global warming this century by soaking up vast amounts of heat from the atmosphere in a shift likely to reverse from around 2030 and spur fast temperature rises, scientists said.
The theory is the latest explanation for a slowdown in the pace of warming at the Earth’s surface since about 1998 that has puzzled experts because it conflicts with rising greenhouse gas emissions, especially from emerging economies led by China.
OSLO, Aug 14 (Reuters) – Man-made greenhouse gas emissions
have become the dominant cause of melting in glaciers from the
Alps to the Andes that is raising world sea levels, a study said
Human emissions accounted for an estimated 69 percent of
loss of ice from glaciers from 1991-2010, overtaking natural
climate variations that had been the main driver of a retreat
since the mid-19th century, researchers wrote in the journal
OSLO, Aug 7 (Reuters) – Deep cuts in greenhouse gas
emissions of 40 to 70 percent by mid-century will be needed to
avert the worst of global warming that is already harming all
continents, a draft U.N. report showed.
The 26-page draft, obtained by Reuters on Thursday, sums up
three U.N. scientific reports published over the past year as a
guide for almost 200 governments which are due to agree a deal
to combat climate change at a summit in Paris in late 2015.
OSLO, Aug 6 (Reuters) – Global warming has been going on for
so long that most people were not even born the last time the
Earth was cooler than average in 1985 in a shift that is
altering perceptions of a “normal” climate, scientists said.
Decades of climate change bring risks that people will
accept higher temperatures, with more heatwaves, downpours and
droughts, as normal and complicate government plans to do more
to cut emissions of greenhouse gas emissions.
OSLO, July 9 (Reuters) – Insect-eating birds are in decline
in parts of the Netherlands where farmers have used pesticides
that are suspected of killing bees vital to crop pollination, a
study showed on Wednesday.
The report is the first evidence that neonicotinoid
pesticides, restricted in the European Union because of worries
about bees, are having knock-on effects on larger creatures by
reducing insect prey such as mosquitoes or beetles.
OSLO (Reuters) – Swathes of the Amazon may have been grassland until a natural shift to a wetter climate about 2,000 years ago let the rainforests form, according to a study that challenges common belief that the world’s biggest tropical forest is far older.
The arrival of European diseases after Columbus crossed the Atlantic in 1492 may also have hastened the growth of forests by killing indigenous people farming the region, the scientists wrote in the U.S. journal Proceedings of the National Academy of Sciences (PNAS).
