Polar Ice

Earth North Pole summer ice pack
This simulation shows how increasing CO2 levels may affect sea ice thickness at the poles. Visualizations are shown for both a control run, where CO2 levels remain constant, and an experimental run, with CO2 levels increasing at 1 percent per year. The 50-year control run reveals no perceptible change in ice thickness. However, after 140 years of integration the increasing CO2 run obtains a quadrupling of atmospheric CO2 and shows a dramatic reduction in sea ice thickness at the North Pole. The ice thickness is depicted with a blue to white color mapping, where white represents the thickest ice.

Ocean Currents

Will global warming trigger a new ice age? (
If climate change disrupts ocean currents, things could get very chilly round here [UK], reports Bill McGuire.
Ocean currents, like the Gulf Stream, are driven by the descent to the sea floor of ice-pack summer melt.
So that the warm, saline surface waters of the Gulf Stream can continue to push northwards, there must be a comparable, deep return current of cold, dense water from the Nordic seas. Disturbingly, this return current seems to have been slowing since the middle of the last century.
Atlantic 'Conveyor Belt' Not Slowing, NASA Study Finds
ScienceDaily (Mar. 29, 2010) — New NASA measurements of the Atlantic Meridional Overturning Circulation, part of the global ocean conveyor belt that helps regulate climate around the North Atlantic, show no significant slowing over the past 15 years. The data suggest the circulation may have even sped up slightly in the recent past.

Sea-level Rise

Indian Ocean Sea-Level Rise Threatens Coastal Areas
Press Release 10-119, July 19, 2010
National Science Foundation
Rise is especially high along coastlines of Bay of Bengal and Arabian Sea, as well as Sri Lanka, Sumatra and Java


A new study concludes that Indian Ocean sea levels are rising unevenly and threatening residents in some densely populated coastal areas and islands. The study, led by scientists at the University of Colorado (CU) at Boulder and the National Center for Atmospheric Research (NCAR) in Boulder, Colo., finds that the sea-level rise is at least partly a result of climate change. Funding for the research came from the National Science Foundation (NSF), NCAR's sponsor, as well as the Department of Energy and NASA.
Sea-level rise is particularly high along the coastlines of the Bay of Bengal and the Arabian Sea, as well as the islands of Sri Lanka, Sumatra and Java, the authors found. The key player in the process is the Indo-Pacific warm pool, an enormous, bathtub-shaped area spanning a huge region of the tropical oceans stretching from the east coast of Africa to the International Date Line in the Pacific. The warm pool has heated by about 1 degree Fahrenheit, or 0.5 degrees Celsius, in the past 50 years, primarily because of human-generated emissions in greenhouse gases.
"Our results from this study imply that if future anthropogenic warming effects in the Indo-Pacific warm pool dominate natural variability, mid-ocean islands such as the Mascarenhas Archipelago, coasts of Indonesia, Sumatra and the north Indian Ocean may experience significantly more sea-level rise than the global average," says scientist Weiqing Han of CU and lead author of a paper published last month in the journal Nature Geoscience.

Convection Heartbeat

Voyage to the Center of the Sun NSF Discovery
The Sun "rings" like a bell —which lets GONG probe its deepest secrets.
New insight into the Sun's core came in the spring of 2000, when NSF-funded researchers analyzing GONG data announced that they had discovered a solar "heartbeat." That is, they'd found that some layers of gas circulating below the sun's surface speed up and slow down in a predictable pattern--about every 16 months. This pattern appears to be connected to the cycle of eruptions seen on the Sun's surface.
Such eruptions can cause significant disturbances in Earth's own magnetic field, wreaking havoc with telecommunications and satellite systems. A major breakthrough in the ability to forecast these so-called solar storms came in the spring of 2000, when NSF-funded astrophysicists, using ripples on the Sun's surface to probe its interior, developed a technique to image explosive regions on the far side of the Sun. Such images should provide early warnings of potentially disruptive solar storms before they rotate towards Earth.”
