CLIMATE ADAPTATION

I want to punch climate change in the face. A blog about the interactions between the built environment, people, and nature.

C’mon. Is this real? Anyone find a link for me?

UPDATE: It’s real! Here’s the video from NASA. It’s not gravity, it’s about charged particles.

Huge dust storm off the coast of Africa creates a river of pollution in the atmosphere. The dust cloud can impact air quality and ecosystem health in the US and Latin America. Via NASA

A piece of Africa—actually lots of them—began to arrive in the Americas in June 2014. On June 23, a lengthy river of dust from western Africa began to push across the Atlantic Ocean on easterly winds. A week later, the influx of dust was affecting air quality as far away as the southeastern United States.

This composite image, made with data from the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP, shows dust heading west toward South America and the Gulf of Mexico on June 25, 2014. The dust flowed roughly parallel to a line of clouds in the intertropical convergence zone, an area near the equator where the trade winds come together and rain and clouds are common. In imagery captured by the Moderate Resolution Imaging Spectroradiometer (MODIS), the dust appeared to be streaming from Mauritania, Senegal, and Western Sahara, though some of it may have originated in countries farther to the east.

Saharan dust has a range of impacts on ecosystems downwind. Each year, dust events like the one pictured here deliver about 40 million tons of dust from the Sahara to the Amazon River Basin. The minerals in the dust replenish nutrients in rainforest soils, which are continually depleted by drenching, tropical rains. Research focused on peat soils in the Everglades show that African dust has been arriving regularly in South Florida for thousands of years as well.

In some instances, the impacts are harmful. Infusion of Saharan dust, for instance, can have a negative impact on air quality in the Americas. And scientists have linked African dust to outbreaks of certain types of toxic algal blooms in the Gulf of Mexico and southern Florida.

Has anyone read this? Looking for the paper.

The paper was debunked. And, apparently, the Guardian misunderstood the paper.

infinity-imagined:

A warmer Arctic could permanently affect the pattern of the high-altitude polar jet stream, resulting in longer and colder winters over North America and northern Europe, US scientists say. The jet stream, a ribbon of high altitude, high-speed wind in northern latitudes that blows from west to east, is formed when the cold Arctic air clashes with warmer air from further south. The greater the difference in temperature, the faster the jet stream moves.

According to Jennifer Francis, a climate expert at Rutgers University, the Arctic air has warmed in recent years as a result of melting polar ice caps, meaning there is now less of a difference in temperatures when it hits air from lower latitudes. “The jet stream is a very fast moving river of air over our head, but over the past two decades the jet stream has weakened. This is something we can measure,” she said Saturday at a meeting of the American Association for the Advancement of Science. As a result, instead of circling the earth in the far north, the jet stream has begun to meander, like a river heading off course. This has brought chilly Arctic weather further south than normal, and warmer temperatures up north. Perhaps most disturbingly, it remains in place for longer periods of time.

I have a feeling this was taken out of context.

The London Array is the world’s largest off-shore windfarm. Via NASA.

Twenty kilometers (12 miles) from England’s Kent and Essex coasts, the world’s largest offshore wind farm has started harvesting the breezes over the sea. Located in the Thames Estuary, where the River Thames meets the North Sea, the London Array has a maximum generating power of 630 megawatts (MW), enough to supply as many as 500,000 homes.

The wind farm became fully operational on April 8, 2013. Twenty days later, the Operational Land Imager (OLI) on the Landsat 8 satellite captured this image of the area. The second image is a closeup of the area marked by the white box in the top image. White points in the second image are the wind turbines; a few boat wakes are also visible. The sea is discolored by light tan sediment—spring runoff washed out by the Thames.

To date, the London Array includes 175 wind turbines aligned to the prevailing southwest wind and spread out across 100 square kilometers (40 square miles). Each turbine stands 650 to 1,200 meters apart (2,100 to 3,900 feet) and 147 meters (482 feet) tall. Each is connected by cables buried in the seafloor, and power is transmitted to two substations offshore and to an onshore station at Cleve Hill.

A NASA satellite snapped this shot today of snow covered U.S. east coast.

The first winter storm of 2014 swept across the northeastern United States on January 1–3, bringing as much as 24 inches (61 centimeters) of snow to the hardest hit areas. The center of the storm was over the North Atlantic Ocean when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image at 10:55 a.m. Eastern Time on January 3.

Lines of clouds over the ocean indicate that strong winds were blowing from the north toward the center of the low-pressure system. The winds pushed the clouds away, leaving a clear view of fresh snow across most of the Northeast.

I am seriously considering stringing for Al Jazeera after my USAID adaptation contract is up. They are, by far in my opinion, leading the world in media, journalism, investigations, and “tone.”

Happy (late) Halloween from me and my great team!
