Gas Injection Probably Triggered Small Earthquakes Near Snyder, Texas

AUSTIN, Texas — A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO₂) — a finding that is relevant to the process of capturing and storing CO₂ underground.

Although the study suggests that underground injection of gas triggered the Snyder earthquakes, it also points out that similar rates of injections have not triggered comparable quakes in other fields, bolstering the idea that underground gas injection does not cause significant seismic events in many geologic settings.

Heute beginnt in Warschau die internationale Klimakonferenz COP 19. Martin Kaiser, Leiter der internationalen Klimapolitik bei Greenpeace, ist selbst in Warschau dabei und beantwortet die wichtigsten Fragen.

Online-Redaktion: Klimakonferenzen scheinen meist das zu produzieren, was sie eigentlich verhindern sollen: heiße Luft. Warum ist Greenpeace trotzdem in Warschau? (more…)

If a tree falls in Brazil…? Amazon deforestation could mean droughts for western U.S.

In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.

The researchers report in the Journal of Climate that an Amazon stripped bare could mean 20 percent less rain for the coastal Northwest and a 50 percent reduction in the Sierra Nevada snowpack, a crucial source of water for cities and farms in California. Previous research has shown that deforestation will likely produce dry air over the Amazon. Using high-resolution climate simulations, the researchers are the first to find that the atmosphere’s normal weather-moving mechanics would create a ripple effect that would move that dry air directly over the western United States from December to February.

Global warming led to dwarfism in mammals — twice

ANN ARBOR — Mammal body size decreased significantly during at least two ancient global warming events. A new finding that suggests a similar outcome is possible in response to human-caused climate change, according to a University of Michigan paleontologist and his colleagues.

Researchers have known for years that mammals such as primates and the groups that include horses and deer became much smaller during a period of warming, called the Paleocene-Eocene Thermal Maximum (PETM), about 55 million years ago. (more…)

Energieverbrauch in Deutschland steigt

Jetzt Kosten sparen durch Gebäudeenergieberatung

Der Energieverbrauch wird in Deutschland laut einer Prognose der AG Energiebilanzen für das Gesamtjahr voraussichtlich um zwei Prozent steigen. Und mit Beginn der kalten Jahreszeit laufen die Heizungsanlagen jetzt wieder auf Hochtouren. Das geht ins Geld. Der NABU empfiehlt daher eine Gebäudeenergieberatung, denn dadurch können nicht nur Energiekosten eingespart, sondern auch das Klima geschützt werden.

„Hauseigentümer und Mieter werden Jahr für Jahr mit steigenden Energiepreisen konfrontiert“, sagte NABU-Bundesgeschäftsführer Leif Miller. Das treibe zum einen die Stromrechnung nach oben, aber noch viel stärker würden die Heizkosten ins Gewicht fallen. „Gut zwei Drittel ihres Geldes verheizen Hauseigentümer und Mieter buchstäblich in den eigenen vier Wänden.“ Für Heizöl, Erdgas und Fernwärme explodierten die Kosten von 2005 bis 2012 um bis zu 62 Prozent.

Pacific Ocean Temperature Influences Tornado Activity in U.S., MU Study Finds

COLUMBIA, Mo. – Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.

Laurel McCoy, an atmospheric science graduate student at the MU School of Natural Resources, and Tony Lupo, professor and chair of atmospheric science in the College of Agriculture, Food and Natural Resources, surveyed 56,457 tornado-like events from 1950 to 2011. They found that when surface sea temperatures were warmer than average, the U.S. experienced 20.3 percent more tornados that were rated EF-2 to EF-5 on the Enhanced Fuijta (EF) scale. (The EF scale rates the strength of tornados based on the damage they cause. The scale has six category rankings from zero to five.) (more…)

Adidas und Nike halten an giftigen Chemikalien fest

Neuer Greenpeace-Bericht entlarvt die zwei weltweit größten Sportartikelhersteller

Adidas und Nike haben bisher zu wenig unternommen, um wie versprochen bis zum Jahr 2020 auf giftige Chemikalien in ihrer Produktion zu verzichten. Auch der chinesische Konzern Li Ning hat noch keine konkreten Schritte eingeleitet, um bis 2020 schadstofffrei zu produzieren. Dies zeigt eine neue Online-Plattform von Greenpeace, der “Detox-Catwalk“.

Dort werden die 17 Modefirmen, die sich im Rahmen der Detox-Kampagne von Greenpeace zum Gift-Ausstieg bis 2020 verpflichtet haben, in die Kategorien „Trendsetter“, „Greenwasher“ und „Schlusslichter“ unterteilt. „Vor zwei Jahren waren Adidas und Nike noch Detox-Vorreiter, haben dann aber den Worten keine Taten folgen lassen. Gerade Adidas macht weiter wie bisher, anstatt konkrete Maßnahmen hin zu einer sauberen und transparenten Textilproduktion zu beginnen“, sagt Manfred Santen, Chemie-Experte von Greenpeace. (more…)
