International Day for Biological Diversity 2015 is 22 May. The theme for the Day this year is “Biodiversity for Sustainable Development”. More than 4,500 mammal, bird and amphibian species are currently deemed at risk of extinction. Not all species have been catalogued, so we do not know exactly how many we are losing each year, but a report recently published in the journal Natuesuggests that approximately 41 per cent of amphibian species, 26 per cent of mammal species and 13 per cent of bird species are likely to be lost in the near future.

Climate change and human rights
Last month, a Peruvian farmer called on German energy company RWE to pay its fair share to protect his home from imminent flooding caused by a glacial lake melted by global warming. “For a long time, my father and I have thought that those who cause climate change should help solve the problems it causes,” Saul Luciano Lliuya told the Guardian. He holds that RWE, one of Europe’s largest emitters of carbon, has contributed to the greenhouse effect causing glacial melting that endangers his home, along with many others in the city of Huaraz.
Lliuya’s story illustrates the tangible human impacts of climate change, which can easily be forgotten amidst high-level debates over carbon emissions reductions. This is a key year for climate action by both governments and companies.
A la alza la exposición al calor extremo en EEUU
La exposición de los residentes estadounidenses al calor extremo podría aumentar de cuatro a seis veces a mediados de siglo, tanto por el calentamiento global como por una población que está creciendo especialmente rápido en las regiones más calientes del país, según una nueva investigación.
El estudio, realizado por investigadores del Centro Nacional de Investigación Atmosférica (NCAR) y la Universidad de la Ciudad de Nueva York (CUNY), pone de relieve la importancia de considerar los cambios sociales cuando se trata de determinar los futuros impactos climáticos.
Can Ice Loss Affect Gravity?
A group of scientists, led by a team from the University of Bristol, has observed a sudden increase of ice loss in a previously stable region of Antarctica. The research is published today in Science.
What are the bright spots on dwarf planet Ceres?
NASA's Dawn mission captured a sequence of images, taken for navigation purposes, of dwarf planet Ceres on May 16, 2015. The image showcases the group of the brightest spots on Ceres, which continue to mystify scientists. It was taken from a distance of 4,500 miles (7,200 kilometers) and has a resolution of 2,250 feet (700 meters) per pixel.
"Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice," Christopher Russell, principal investigator for the Dawn mission from the University of California, Los Angeles, said recently.
Fine Particulate Air Pollution Linked to Increased Risk of Childhood Autism
Exposure to fine particulate air pollution during pregnancy through the first two years of a child’s life may be associated with an increased risk of the child developing autism spectrum disorder (ASD), a condition that affects one in 68 children, according to a University of Pittsburgh Graduate School of Public Health investigation of children in southwestern Pennsylvania. The research is funded by The Heinz Endowments and published in the July edition of Environmental Research.
