Warmer climate contributes to spread of the Zika virus
February 10, 2016 09:51 AM - Nadia Pontes, The Ecologist
The Aedes mosquitos that carry the Zika virus and dengue fever are not just perfectly adapted to life in cities, writes Nadia Pontes. They are also being helped along by warming climates which increase their range. It's time to get serious about the health implications of a hotter planet.
Global warming affects the abundance and distribution of disease vectors. As regions that used to be drier and colder start to register higher temperatures and more rain, mosquitoes expand their breeding areas, which increases the number of populations at
The explosion in the number of Latin American cases of microcephaly - a congenital condition associated with maldevelopment of the brain - has become an international emergency due its "strongly suspected"link with the rapidly spreading Zika virus, according to the World Health Organisation(WHO).
Climate change will delay transatlantic flights
February 10, 2016 07:21 AM - Pete Castle, Reading University.
Planes flying between Europe and North America will be spending more time in the air due to the effects of climate change, a new study has shown.
By accelerating the jet stream – a high-altitude wind blowing from west to east across the Atlantic – climate change will speed up eastbound flights but slow down westbound flights, the study found. The findings could have implications for airlines, passengers, and airports.
Are we impacting the future of our planet for thousands of years?
February 9, 2016 09:12 AM - Oregon State University/Lawrence Livermore National Laboratory
The Earth may suffer irreversible damage that could last tens of thousands of years because of the rate humans are emitting carbon into the atmosphere.
In a new study in Nature Climate Change, researchers at Oregon State University, Lawrence Livermore National Laboratory and collaborating institutions found that the longer-term impacts of climate change go well past the 21st century.
“Much of the carbon we are putting in the air from burning fossil fuels will stay there for thousands of years — and some of it will be there for more than 100,000 years,” said Peter Clark, an Oregon State University paleoclimatologist and lead author on the article. “People need to understand that the effects of climate change on the planet won’t go away, at least not for thousands of generations.”
LLNL’s Benjamin Santer said the focus on climate change at the end of the 21st century needs to be shifted toward a much longer-term perspective.
The uneven impacts of climate change
February 7, 2016 09:14 AM - Wildlife Conservation Society via ScienceDaily
A new study by University of Queensland and WCS shows a dramatic global mismatch between nations producing the most greenhouse gases and the ones most vulnerable to the effects of climate change.
The study shows that the highest emitting countries are ironically the least vulnerable to climate change effects such as increased frequency of natural disasters, changing habitats, human health impacts, and industry stress.
Those countries emitting the least amount of greenhouse gases are most vulnerable.
Universtiy of Alaska studies how the melting Greenland glaciers are impacting sea levels
February 6, 2016 08:41 AM - University of Alaska Fairbanks via ScienceDaily
University of Alaska Fairbanks mathematicians and glaciologists have taken a first step toward understanding how glacier ice flowing off Greenland affects sea levels.
Andy Aschwanden, Martin Truffer and Mark Fahnestock used mathematical computer models and field tests to reproduce the flow of 29 inlet glaciers fed by the Greenland ice sheet. They compared their data with data from NASA's Operation IceBridge North aerial campaign.
The comparisons showed that the computer models accurately depicted current flow conditions in topographically complex Greenland.
Kalligrammatid lacewings looked like butterflies, but lived millions of years before butterflies
February 4, 2016 01:00 PM - JOHN BARRAT Smithsonian News
New fossils found in Northeastern China have revealed a remarkable evolutionary coincidence: an extinct group of insects known as Kalligrammatid lacewings (Order Neuroptera) share an uncanny resemblance to modern day butterflies (Order Lepidoptera). Even though they vanished some 50 million years before butterflies appeared on earth, they possess the same wing shape and pigment hues, wing spots and eyespots, body scales, long proboscides, and similar feeding styles as butterflies.
A photo of the modern owl butterfly (“Caligo Memnon”) shown beside a fossilized Kalligrammatid lacewing (“Oregramma illecebrosa”) shows some of the convergent features independently evolved by the two distantly-related insects, including wing eyespots and wing scales.

In an incredible example of convergent evolution, both butterflies and kalligrammatids evol
Phases of the moon affect amount of rainfall
February 1, 2016 07:20 AM - Hannah Hickey, University of Washington
When the moon is high in the sky, it creates bulges in the planet’s atmosphere that creates imperceptible changes in the amount of rain that falls below. New University of Washington research to be published in Geophysical Research Letters shows that the lunar forces affect the amount of rain – though very slightly.
Iowa - first in primaries, first in wind power
January 31, 2016 08:25 AM - Zachary Davies Boren / Greenpeace Energydesk, The Ecologist
As presidential contenders gather in Iowa for the beginning of the party selection season, they may have noticed a lot of wind turbines, writes Zachary Davies Boren. And if they have any sense, they will find only nice things to say about them. Wind supplies 30% of the state's power, more than any other US state, and Iowans are all for it. Ted Cruz, mind your words!
Today, there are 12 factories in Iowa that build wind-related parts and materials, and wind supports as many as 7,000 jobs. Furthermore, the steady long-term costs of wind power promise to keep Iowa's electricity prices stable for many years to come.
All eyes are on Iowa, the midwestern state set to kick-off the US presidential election next week with its folksy first-in-the-nation caucus.
Paris climate agreement seen as turning point by UN
January 30, 2016 08:06 AM - United Nations News Centre
Less than two months after 196 parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, the global community is already seeing signs of it being a decisive turning point, according to a senior UN official dealing with climate issues.
A month and a half since 196 parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, the global community is already seeing signs of it being a decisive turning point, according to a senior UN official dealing with climate issues.
“Much has been happening since Paris – the World Meteorological Organization (WMO) confirmed that 2015 was the hottest year on record, not just by a little but by a lot,” Janos Pasztor, who was today appointed as Senior Adviser to the Secretary-General on Climate Change, told reporters at a briefing in New York.
Meat consumption and climate change linked by EU study
January 28, 2016 07:22 AM - Sarantis Michalopoulos, EurActiv
The overconsumption of meat will inevitably push global temperatures to dangerous levels, a recent study has warned, urging reluctant governments to take action.
The world's rapidly expanding population is posing a huge challenge to farmers. A reportpublished in November 2015 by Chatham House, and the Glasgow University Media Group, examined the interconnection between meat and dairy consumption with climate change.
Nearly one-third of the world's cultivated land is being used to grow animal feed. In the EU alone, 45% of wheat production is used for this purpose, with 30% of overall use met by imports.
