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.

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.
¿PodrÃa el embotellamiento de California generar electricidad para la red?
California está probando si su tráfico pesado puede producir no sólo emisiones y contaminación del aire, sino también electricidad. La Comisión de Energía del Estado informa que invertirá $ 2 millones de dólares para examinar el potencial de utilizar cristales piezoeléctricos incorporados bajo el asfalto como una forma de enviar la energía creada por los coches en movimiento a la red.
92% of the world's population exposed to unsafe levels of air pollution
A new WHO air quality model confirms that 92% of the world's population lives in places where air quality levels exceed WHO limits. Some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air pollution can be just as deadly. In 2012, an estimated 6.5 million deaths (11.6% of all global deaths) were associated with indoor and outdoor air pollution together.
Longest record of continuous carbon flux data is now publicly available
Around the world -- from tundra to tropical forests, and a variety of ecosystems in between -- environmental researchers have set up micrometeorological towers to monitor carbon, water, and energy fluxes, which are measurements of how carbon dioxide (CO2), water vapor and energy (heat) circulate between the soil, plants and atmosphere. Most of these sites have been continuously collecting data, some for nearly 25 years, monitoring ecosystem-level changes through periods of extreme droughts and rising global temperatures. Each of these sites contributes to a regional network -- i.e. the European Network (Euroflux) or the Americas Network (AmeriFlux) -- and the regional networks together comprise a global network called FLUXNET.
Probablemente no le costará más el volver a casa en un auto amigable con el medio ambiente
Ha sido una creencia común que los vehículos de bajas emisiones, como los híbridos y coches eléctricos, son más caros que otras opciones. Pero un nuevo estudio revela que cuando los costos de operación y mantenimiento se incluyen en el precio de un vehículo, los coches más limpios en realidad pueden ser una mejor apuesta.
