While people everywhere are trying to figure out how to slow down global warming, scientists continue to look at the effects it's having on different species. For example, researchers at North Carolina State University, Case Western Reserve University, the Instituto de Pesquisas Ecológicas in Brazil, and the University of Maryland study butterflies. It's known that butterflies naturally "emerge earlier in North Carolina than they do in New England, because it's warmer", so these scientists were wondering what would happen if everywhere is getting warmer, specifically urban cities. The results of the study showed that "the combined effect of an urban area and a warmer part of the state appeared to delay emergence in seven of the 20 species" studied. The scientists don't know what the tipping point is, and may never find out. This research is difficult and the species aren't always able to adapt.

Green clouds on the horizon for computing
http://www.sciencedaily.com/releases/2014/04/140428074644.htm
With new technology developing everyday, it's hard for even a teenager to keep up. But one has to wonder what the environmental impact-positive or negative-of each new invention is. Dietmar Nedbal and Mark Stieninger from the University of Applied Sciences Upper Austria in Steyr, Austria researched just that, specifically focusing on the use of "the cloud" by current apple products. According to their research, "small businesses could save up to 62% of energy costs by switching to a cloud computing system". But, as with every research and every new technology, there are controversies. As put in the article, "there have been concerns that cloud computing does not reduce energy demands and emissions, but simply displaces them" or that "increased internet traffic" would increase energy use and pollution. But, according to the research of Stienhinger and Nedbal, cloud usage is a positive thing for the environment, proving that it reduces carbon dioxide emissions and costs by more than half.

Some corals adjusting to rising ocean temperatures

Climate change is having an affect on everything. Steve Palumbi is a scientist at Stanford who led research about corals affected by climate change, actually finding out that some "can quickly switch on or off certain genes in order to survive in warmer-than-average waters". The reason they have to adjust to the new water temperatures is because of climate change. For example, even 86 degree water, while seemingly normal to the human senses, is deadly for coral. So how are they coping with warmer climates every day. So how do they cope? According to Palumbi, "corals, like people, have adaptive genes that can be turned on or off when external conditions change", which is good because corals are essential to fisheries, aquaculture and storm protection, These apparent adaptive qualities found in these corals will help them survive for at least a few more years than they were predicted, according to the harsh effects of climate change.

How costly are natural hazards? Experts link cost assessment with risk management
http://www.sciencedaily.com/releases/2014/04/140426155351.htm
Risk assessment has always been a fascinating topic to me. Heidi Kreibick is a scientist at the German Research Centre for Geosciences GFZ and is leading a group of international scientists in a study looking at how to better assess risk and what it would actually take to educate people more, specifically about the costs of natural hazards, which are now at "historically high levels". One of the major flaws of people's assessments on disaster costs are what are called "indirect damage". Examples of indirect damages would be factories forced to shut down. According to Kreibich, "the cost assessment cycle involved the continuous monitoring of costs associated with the natural risk management, thus enabling the early detection of inefficient risk mitigation strategies". Not only jut everyday people predict risk, but it's more important on the national level where leaders have to make precautionary decisions. In order to do so efficiently, they first must understand the true risk.
