Does past sea level rise portend future rise from warming?
July 19, 2015 07:13 AM - Steve Williams, Care2
You may have seen claims in recent weeks that historic records show a global temperature rise could give us sea levels 20 feet higher than the norm. How accurate are these claims, and why is it important that we take this issue seriously?
The reports are a result of a University of Florida study that was recently published in the journal Science. The researchers, including lead author Andrea Dutton, wanted to investigate how historically Greenland and Antarctic ice sheets have reacted to global temperature rises and therefore get a glimpse of how current climate change might impact our sea levels.
Welcome three new National Monuments
July 17, 2015 06:59 AM - Judy Molland, Care2
Using his authority under the Antiquities Act of 1906, President Obama announced last week that he was creating three new national monuments. The President designated scenic mountains in California as Berryessa Snow Mountain National Monument, pristine wilderness landscapes in Nevada as Basin and Range National Monument, and a fossil-rich site in Texas as Waco Mammoth National Monument.
Together, the new monuments protect more than one million acres of public lands. National monuments are similar to national parks, except that they can be created from any land owned or controlled by the federal government via a presidential proclamation. With these new designations, Obama will have used the Antiquities Act to establish or expand 19 national monuments in the United States in total. Altogether, he has protected more than 260 million acres of public lands and waters.
How microbes are cleaning up the BP oil spill
July 12, 2015 07:06 AM - Lizabeth Paulat, Care2
Microbes, primarily bacteria and fungi, get a bad rap in today’s society. However they’ve long played an incredible role within the Earth’s ecosystem. And one of the most important places microbes are transforming the earth is in the Gulf of Mexico, where a number of strains are busy munching up the oil still left over from the Deepwater Horizon oil spill disaster.
The Deepwater Horizon oil spill, which took place just over five years ago caused a massive ecological disaster in and around the Gulf of Mexico. This is partially because the spill took so long to quell, with oil companies scrambling (and often failing) to stem the flow of oil from the seabed.
BP to pay billions in oil spill settlement
July 10, 2015 07:18 AM - Chris Sosa, Care2
BP has finally agreed to pay for the incredible damage it caused after the headline-grabbing oil disaster in 2010. The company made overtures at responsibility in the past, but this is the farthest BP has gone toward remedying the mess it made during the Deepwater Horizon Oil Spill.
Care2 has been vocal in demanding accountability for the company. A petition garnering over 150,000 signatures was delivered to BP’s offices, but the BP refused to accept the petition.
It seems BP has run out of options and will now be paying billions of dollars in a pending settlement.
Are kangaroos left-handed?
July 6, 2015 12:11 PM - Judy Molland, Care2
President Obama, Oprah Winfrey, and Bill Gates are all lefties, and now they have unusual colleagues: kangaroos. According to a new study, some wild kangaroos tend to favor their left hands during common tasks like grooming and feeding. Yegor Malashichev, a Russian zoologist from Saint Petersburg State University and a co-author of the study, traveled to Australia to do the fieldwork. Along with his colleagues, he spent long hours observing seven species of marsupials living in the wild. Those species included red-necked wallabies, Goodfellow’s tree kangaroo, the eastern grey kangaroo, and the red kangaroo. The team watched as the animals groomed themselves, grabbed food with their paws, and leaned on their forearms while eating grass. Two species of kangaroo and one wallaby all showed the left-handed trend; some other marsupials, which walk on all fours, did not show the same bias. This new knowledge might seem pretty interesting in itself, but more importantly, the study, published in the journal Current Biology, could give scientists a better understanding of the evolution of mammals.
Beware the Giant Toxic Algae Bloom
June 26, 2015 07:56 AM - Lizabeth Paulat, Care2
Humans and animals on the west coast should take care when near the water. One of the largest algae blooms of all time is producing dangerous toxins which now stretch from California to Alaska. The neurotoxin being released by the bloom is called domoic acid, and it can cause a series of problems for any mammal that comes into contact with it.
Using Invasive Species to Defeat Another Invasive Species
June 25, 2015 10:35 AM - Kevin Mathews, Care2
The forests of Denver, Colo., are currently under attack by an invasive insect species from Asia. So what is the scientists’ plan to stop this assault on trees? They’re going with the controversial move of introducing a second invasive species to destroy the first one. If it sounds like that children’s song about the old lady who swallowed the spider to catch the fly, that’s because it basically is. Unleashing a second non-native species might help to eradicate the first species, but it can also unleash a series of other consequences. Previous experiments in this invasive species vs. invasive species tactic have worked out with various degrees of success, as these four examples will show.
Why do Americans waste so much food?
June 23, 2015 04:11 PM - Judy Molland, Care2
Americans throw away nearly half of their food every year, waste worth roughly $165 billion annually, according to a study by the Natural Resources Defense Council (NRDC). The report estimates that the average American family of four ends up throwing away an equivalent of up to $2,275 annually in food. Even worse, there is evidence that there has been a 50 percent jump in U.S. food waste since the 1970s.
What is the value of bees?
June 21, 2015 09:55 AM - Steve Williams, Care2
What are bees worth to our economy? A group of researchers have attempted to do the math, and the result shows exactly why we need to protect our pollinating bees but also why we can’t rely on economic worth alone to make our arguments for saving threatened species.
It may sound slightly abhorrent to put a price on a living creature–and, to an extent, it is. But calculating the monetary worth of wildlife and, in particular, their place in the overall economy has become a useful way for researchers to communicate to governments and even businesses that they need to take a closer look at preventing species die-out. When it comes to bees however, researchers have found an interesting fact that they say shows the worth and the shortcomings of this approach.
The Dangers of Microbeads in Personal Care Products
June 3, 2015 12:26 PM - s.e. smith, Care2
Microbeads, those tiny plastic beads included in personal care products for exfoliating power, have been popular for a number of years, with a growing number of companies sneaking them into toothpaste, body scrubs, soap and more. That’s despite evidence that they cause significant environmental problems, an issue that’s led a number of states to ban them or seriously consider such bans in order to protect the environment. But there’s more: There’s evidence that microbeads are also harmful for human health.
