The environment in which all weather events occur is not what it used to be. All storms, without exception, are different. Even if most of them look just like the ones we used to have, they are not the same

On top of those issues, one major consumer of recyclables—China—has implemented recent changes that add to recycling woes. These include new regulations on importing materials as well as a new emphasis on the use of domestic sources. A general slowdown of manufacturing in the country hasn't helped, either.
There are different levels of processing, as Mandy Oaklander wrote in Time when reporting on a recent study. A bagged salad would count as “minimally processed.” A single food that has just had something added to it, like oil or sugar, would be “basic processed.” “Moderately processed” foods have additives but are still recognizable in their true form as meat or vegetables or what have you. “Highly processed” foods are made of multiple ingredients, and there’s no way to know where anything originally came from. In the study, 61 percent of Americans’ calories came from highly processed foods, and 16 percent from moderately processed.
Over two months, they caught ten calving events that generated glacial earthquakes detected by the global network of seismometers. In one representative example, a 790-meter-thick iceberg with a top area of almost half a square kilometer cracked off and rotated up onto its side. During that process, which took several minutes to play out, the GPS sensors back from the edge moved about ten centimeters back away from the water, before shifting back to their original position. The sensors also sunk downwards a similar amount, only to bob back up.
For the remaining justices, it simply doesn't matter when economic considerations are taken into account, as long as they are. "The question is whether EPA can reasonably find it 'appropriate' to trigger the regulatory process based on harms (and technological feasibility) alone," Justice Kagan wrote, "given that costs will come into play, in multiple ways and at multiple stages, before any emission limit goes into effect." In the minority's opinion, economics is a central part of the rulemaking process, which necessarily comes after the decision that rules are needed.
But airlines are increasingly under pressure to reduce carbon emissions. The Obama administration proposed this month that new limits on aviation emissions be developed, and the International Civil Aviation Organization, a United Nations agency, is expected to complete its own negotiations on limiting carbon pollution by February 2016.
“There is a significant role for biofuels within the aviation sector, specifically for reducing carbon emissions,” said Debbie Hammel, a senior resource specialist at the Natural Resources Defense Council, who focuses on biofuel.
