Elevated carbon dioxide conditions pose threat for the Monarch butterfly

Milkweed plants from the chambers were fed to hundreds of monarch caterpillars this summer. Milkweed is a monarch caterpillar’s only food, satisfying its nutritional needs while providing an invaluable medicinal boost. The plant’s leaves contain a bitter toxin that helps the insects ward off predators and parasites. But previous work at U-M’s northern Michigan biological…

Greenland Ice Mass Loss: Jan. 2004 – June 2014

GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth’s gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the…

Sea level rise of the past 23 years explained

Oceanographer Josh Willis from NASA’s Jet Propulsion Laboratory narrates this video about the causes of sea level rise and how sea level has changed over the last two decades as observed by the Jason series of satellite missions. Source

The troubling reasons why NASA is so focused on studying sea level rise

Doubling times of 10, 20 or 40 years yield sea level rise of several meters

According to a new study, sea level rise of several meters might happen faster then previously thought. Based on data from past climate changes, when sea level rose to +5–9 m, including the occurrence of extreme storms – during a time when temperatures were less than 1 ◦C warmer than today, experts warn of similar…

The dangerous silence on climate change and extreme weather

We know that CO2 emissions are bad for climate and subsequently the weather. We know that we have to do something about it, because if not things will turn really ugly with large scale carbon releases (i.e. permafrost melt). However, the current projected changes are bad for many, and because of irreversible changes. So why then is…

Eric Rignot: Observations suggest that ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated

Eric Rignot Professor of Earth system science at the University of California, Irvine, and scientist at NASA’s Jet Propulsion Laboratory was interviewed on sea level rise and projections. Ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated Machens: As an ice sheet expert, how do you see the sea-level projections…

We need to really begin the phase out of CO2 emissions

Think of climate change as a cancer. Your doctor told you that he spotted what appears to be likely a melanoma skin cancer, but he is not 100% sure. Do you wait till the signs become more apparent? The cancer might spread in your body, by that diminishing the chance for survival, or do you ask the…

Epic flooding in Texas, during El Nino year and locked Jet Stream configuration

Tornadoes, flooding, and stormy weather currently affects large parts of central Texas. There is also live coverage, for example IBT, The WeatherChannel, or AccuWeather. The situation is still developing, because of possible dam breaches, downed power lines and trees, and black outs. Further precipitation is likely at the end of the week. Governor Greg Abbott called the deadly flooding…

Over 500 dead across India as heat wave sets in, Telangana’s Khammam sizzles at 48 degrees

Hindustan Times: Humans “boil in their own skin” at 48 degrees Celsius, the maximum temperature recorded at Khammam in Telangana which has become the focal point of a blistering heat wave sweeping through swathes of India on Sunday, killing nearly 500 people. Allahabad was the second hottest at 47.7°C, six degrees above normal; Nandigama in…
