A lo largo de los EE.UU., los árboles están muriendo a una velocidad sorprendente. Las razones de la mortandad varían de un lugar a otro: la sequía, las enfermedades, los insectos y los incendios forestales. Pero la causa fundamental en muchos de estos casos es el mismo: el cambio climático.

First evidence of deep-sea animals ingesting microplastics
Following the news that the UK government is to ban plastic microbeads by the end of 2017, a team of scientists led by the University of Oxford has discovered the first evidence of microplastics being ingested by deep-sea animals.
Researchers working on the Royal Research Ship (RRS) James Cook at two sites in the mid-Atlantic and south-west Indian Ocean found plastic microfibres inside creatures including hermit crabs, squat lobsters and sea cucumbers at depths of between 300m and 1800m.
Wetlands and agriculture, not fossil fuels could be causing a global rise in methane
Research published today in the American Geophysical Union’s journal Global Biogeochemical Cyclesshows that recent rises in levels of methane in our atmosphere is being driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.
Potentially harmful chemicals widespread in household dust
Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a study led by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. The multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust. They found that DEHP, a chemical belonging to a hazardous class called phthalates, was number one on that list. In addition, the researchers found that phthalates overall were found at the highest levels in dust followed by phenols and flame retardant chemicals.
5 Species Most Likely to Survive a Climate Change Disaster
Survival of the fittest. This basic tenet of evolution explains why the dodo bird no longer exists and why humans have opposable thumbs.
Adaptation is key to survival, no matter how many fingers you’ve got. The ability to adjust to whatever conditions Mother Earth sends our way determines whether obstacles lead to extinction or to a new generation.
Human-accelerated climate change is a disaster waiting to happen. We’ve already seen the superstorms and drought it can create. Although we can work to slow climate change, there’s no way to stop it completely. This reality means adaptation will once again become the most important strategy for survival.
One thing’s for sure: the Earth will continue to exist as it has for eons. The question is, what will be left behind to inhabit it?
Below are five species known for their resilience and ability to survive in adverse conditions. They are the most likely to survive a climate change disaster. Spoiler: humans don’t make the list.
Technique could assess historic changes to Antarctic sea ice and glaciers
Historic changes to Antarctic sea ice could be unraveled using a new technique pioneered by scientists at Plymouth University.
It could also potentially be used to demonstrate past alterations to glaciers and ice shelves caused by climatic changes, a study published in Nature Communications suggests.
The new method builds on an existing technique, also developed by Plymouth University over the last 10 years, which identified a means by which scientists could measure changes to sea ice in the Arctic.
