Sneak Peek at DSCOVR

DSCOVR is launched and on its way!

February 12, 2015 The DSCOVR satellite with its EPIC cam, PlasMag & NISTAR instrument package is on the way... a million mile journey, scheduled to light up, be tested and begin delivering data to Earth in August, including near-real-time imaging of Earth provided online – We will be delivering a stream of amazing imagery of our planet as NASA/NOAA begin uploading EPICs pictures of us!

○

It's been some time since December 7, 1972 when the only picture ever snapped by a human of the whole earth was captured -- our iconic "Blue Marble" -- Engineers that they are, NASA named the image -- AS17-148-22727

As we have been recalling the history, we haven't had returned to us a 'whole earth' image since 1972. Today, Feb 10, the Associated Press reports Sen. Bill Nelson, D-Florida, pointing out from Washington that there hasn't been a full, sunlit picture of the Earth since Apollo 17 in 1972 - NASA's last manned moon-landing mission. Subsequent images have been stitched together, the Senator explained, for composite shots. The Senator has an exceptional point of view as he was an astronaut -- In January 1986, Nelson spent six days orbiting Earth as a payload specialist aboard space shuttle Columbia. His NASA bio adds "The experience gave him a new perspective on the Earth’s fragile environment and a greater appreciation of the importance of our nation’s space exploration program."

The DSCOVR satellite launches into deep orbit with multiple missions -- to monitor space weather and, due to the satellite's orbital distance from Earth (1 mil miles), DSCOVR will be sending back daily images of the 'whole earth' via its EPIC image-taking system and via its NISTAR system measuring earth's earth's temperature, our "radiation balance" ("albedo").

Global Warming / NASA OCO Satellite Sends Back Most Detailed CO2 View Ever / Dec 18

Initial round of CO2data is made available...

A first full set of CO2 data will likely be available after March 2015 for scientists and public to download and explore.

More on the history-making OCO-2 / Orbiting Carbon Observatory

According to JPL scientists: "Where OCO-2 really excels is the sheer amount of data being collected within a day, about one million measurements across a narrow swath... For fluorescence, this enables us, for the first time, to look at features on the five- to 10-kilometer scale on a daily basis." SIF can be measured even through moderately thick clouds, so it will be especially useful in understanding regions like the Amazon where cloud cover thwarts most spaceborne observations."

The changes in atmospheric carbon dioxide that OCO-2 seeks to measure are so small that the mission must take unusual precautions to ensure the instrument is free of errors. For that reason, the spacecraft was designed so that it can make an extra maneuver. In addition to gathering a straight line of data like a lawnmower swath, the instrument can point at a single target on the ground for a total of seven minutes as it passes overhead. That requires the spacecraft to turn sideways and make a half cartwheel to keep the target in its sights.

The targets OCO-2 uses are stations in the Total Carbon Column Observing Network (TCCON), a collaborative effort of multiple international institutions. TCCON has been collecting carbon dioxide data for about five years, and its measurements are fully calibrated and extremely accurate. At the same time that OCO-2 targets a TCCON site, a ground-based instrument at the site makes the same measurement. The extent to which the two measurements agree indicates how well calibrated the OCO-2 sensors are.

Additional maps released recently showed the results of these targeting maneuvers over two TCCON sites in California and one in Australia. "Early results are very promising," said Paul Wennberg, a professor at Caltech and head of the TCCON network. "Over the next few months, the team will refine the OCO-2 data, and we anticipate that these comparisons will continue to improve."

Permafrost Loss

Estimates of permafrost loss... consequences

2016

https://nsidc.org/sites/nsidc.org/files/images/cryosphere/fig1.gif

Scientists estimate that five times as much carbon might be stored in frozen Arctic soils — permafrost — as has been emitted by all human activities since 1850. This worries people who study global warming. While emissions from permafrost currently account for less than 1 percent of global methane emissions, some researchers think this could change in dramatic ways as the world warms and that carbon-rich frozen soil breaks down.

The map above, based on data provided by the National Snow and Ice Data Center, shows the extent of Arctic permafrost. Any rock or soil remaining at or below 0 degrees Celsius (32 degrees Fahrenheit) for two or more years is considered permafrost.

Continuous permafrost, which occurs in the coldest areas, refers to areas where frozen soil underlies more than 90 percent of the surface. Discontinuous permafrost occurs in slightly warmer areas, where frozen soils underlie 50 to 90 percent of the surface, while certain features such as rivers and south-facing slopes may be ice-free. In areas with sporadic permafrost, frozen soils underlie 10 to 50 percent of the surface. In areas with isolated permafrost, frozen soils underlie less than 10 percent of the surface, usually only occurring in depressions or north-facing slopes.

Permafrost Threatened

http://www.usgs.gov/newsroom/article.asp?ID=4400

Using statistically modeled maps drawn from satellite data and other sources, U.S. Geological Survey scientists have projected that the near-surface permafrost that presently underlies 38 percent of boreal and arctic Alaska would be reduced by 16 to 24 percent by the end of the 21st century under widely accepted climate scenarios. Permafrost declines are more likely in central Alaska than northern Alaska.

Northern latitude tundra and boreal forests are experiencing an accelerated warming trend that is greater than in other parts of the world. This warming trend degrades permafrost, defined as ground that stays below freezing for at least two consecutive years. Some of the adverse impacts of melting permafrost are changing pathways of ground and surface water, interruptions of regional transportation, and the release to the atmosphere of previously stored carbon.

“A warming climate is affecting the Arctic in the most complex ways,” said Virginia Burkett, USGS Associate Director for Climate and Land Use Change. “Understanding the current distribution of permafrost and estimating where it is likely to disappear are key factors in predicting the future responses of northern ecosystems to climate change.”

https://en.wikipedia.org/wiki/Tundra

A severe threat to tundra is global warming, which causes permafrost to melt. The melting of the permafrost in a given area on human time scales (decades or centuries) could radically change which species can survive there.

Another concern is that about one third of the world's soil-bound carbon is in taiga and tundra areas. When the permafrost melts, it releases carbon in the form of carbon dioxide and methane, both of which are greenhouse gases. The effect has been observed in Alaska. In the 1970s the tundra was a carbon sink, but today, it is a carbon source. Methane is produced when vegetation decays in lakes and wetlands.

The amount of greenhouse gases which will be released under projected scenarios for global warming have not been reliably quantified by scientific studies, although a few studies were reported to be underway in 2011. It is uncertain whether the impact of increased greenhouse gases from this source will be minimal or massive.

A self-reinforcing positive feedback loop is akin to a "vicious circle": It accelerates the impacts of anthropogenic climate disruption (ACD). An example would be methane releases in the Arctic. Massive amounts of methane are currently locked in the permafrost, which is now melting rapidly. As the permafrost melts, methane - a greenhouse gas 100 times more potent than carbon dioxide on a short timescale - is released into the atmosphere, warming it further, which in turn causes more permafrost to melt, and so on...

Predicted rate of temperature change in Arctic

Arctic temperatures are expected to increase at roughly twice the global rate. The Intergovernmental Panel on Climate Change (IPCC) will in their fifth report establish scenarios for the future, where the temperature in the Arctic will rise between 1.5 and 2.5°C by 2040 and with 2 to 7.5°C by 2100. Estimates vary on how many tons of greenhouse gases are emitted from thawed permafrost soils. One estimate suggests that 110-231 billion tons of CO2 equivalents (about half from carbon dioxide and the other half from methane) will be emitted by 2040, and 850-1400 billion tons by 2100. This corresponds to an average annual emission rate of 4-8 billion tons of CO2 equivalents in the period 2011-2040 and annually 10-16 billion tons of CO2 equivalents in the period 2011-2100 as a result of thawing permafrost. For comparison, the anthropogenic emission of all greenhouse gases in 2010 is approximately 48 billion tons of CO2 equivalents. Release of greenhouse gases from thawed permafrost to the atmosphere may increase global warming.

Plankton Swirl -- Climate Dance

Phytoplankton Oxygen Factories in the Southern Ocean

NASA Earth Observatory

Phytoplankton are ecosystems of the sea. They are floating, drifting, plant-like organisms that harness the energy of the Sun, mix it with carbon dioxide that they take from the atmosphere, and turn it into carbohydrates and oxygen.

Phytoplankton are critical to the marine food web, being the primary producers of food for the oceanic food web, from zooplankton to fish and shellfish to whales.

Like plants and trees on land, phytoplankton give us a lot more than food. It is estimated that 50 to 80 percent of the oxygen in our atmosphere has been produced by phytoplankton. At the same time, they are responsible for drawing down significant portions of the carbon dioxide from the air. The tiniest of living organisms exert an outsized influence on the planet.

Phytoplankton rapidly disappearing

Loss of mini marine plants at base of food web threatens sea’s ecology

A rapid loss of phytoplankton threatens to turn the western Indian Ocean into an “ecological desert,” a new study warns. The research reveals that phytoplankton populations in the region fell an alarming 30 percent over the last 16 years.

A decline in ocean mixing due to warming surface waters is to blame for that phytoplankton plummet, researchers propose online January 19 in Geophysical Research Letters. The mixing of the ocean’s layers ferries phytoplankton nutrients from the ocean’s dark depths up into the sunlit layers that the mini plants inhabit.

The loss of these microbes, which form the foundation of the ocean food web, may undermine the region’s ecosystem, warns study coauthor Raghu Murtugudde, an oceanographer at the University of Maryland in College Park.

“If you reduce the bottom of the food chain, it’s going to cascade...”
