New Satellite's Lasers Will Track Tiny Changes in Polar Ice

New Satellite's Lasers Will Track Tiny Changes in Polar Ice

Once it settles into orbit 310 miles above the Earth, the satellite will start collecting data using a specially designed laser device that will give scientists more data about exactly where ice is melting and how fast.The NASA satellite will scan the Earth’s surface using six green laser beams to measure glaciers and floating sea ice.

Large piece of Lowell Glacier quickly becomes pond of slush – Climate Change: Vital Signs of the Planet

Lowell Glacier, July 22-26, 2018 NASA Earth Observatory images by Joshua Stevens, using Landsat data from the U.S. Geological Survey and modified Copernicus Sentinel data (2018) processed by the European Space Agency.

Extreme weather in Europe linked to less sea ice and warming in the Barents Sea

Extreme weather in Europe linked to less sea ice and warming in the Barents Sea

During years with low seasonal sea ice concentrations (when there’s more heat loss from more exposed open water), the north-south differences in atmospheric temperatures across the Barents Sea are reduced.

Climate change: Heat below Arctic is MELTING ice - sea levels WILL rise

Climate change: Heat below Arctic is MELTING ice - sea levels WILL rise

Climate change: Heat below Arctic is MELTING ice - sea levels WILL rise THE ARCTIC ice is being attacked by warmth from all fronts, according to new research which could exacerbate the problem of rising sea levels.

A New 'Brown Tide' Could Make Florida's Dangerous Red Tide Worse

A New 'Brown Tide' Could Make Florida's Dangerous Red Tide Worse

The beaches of southwest Florida are once again graveyards for marine life, thanks to a deadly "red tide" algal bloom floating just beneath the surface of the water offshore.

Arctic carbon cycle is speeding up – Climate Change: Vital Signs of the Planet

Arctic carbon cycle is speeding up – Climate Change: Vital Signs of the Planet

A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABoVE) shows that carbon in Alaska's North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago.

Expedition probes ocean’s smallest organisms for climate answers – Climate Change: Vital Signs of the Planet

Expedition probes ocean’s smallest organisms for climate answers – Climate Change: Vital Signs of the Planet

With more than 100 scientists and crew from nearly 30 research institutions, EXPORTS is the first coordinated multidisciplinary science campaign of its kind to study the pathways, fates and carbon cycle impacts of microscopic and other plankton using two research vessels, a range of underwater robotic platforms and satellite imagery.

Carbon monoxide from California wildfires drifts east – Climate Change: Vital Signs of the Planet

Carbon monoxide from California wildfires drifts east – Climate Change: Vital Signs of the Planet

New images made with data acquired by the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite show the high concentrations of carbon monoxide emitted from the fires (in orange/red) between July 29 and August 8.

Scientists find pocket of warm water trapped under Arctic with potential to melt entire ice pack

Scientists find pocket of warm water trapped under Arctic with potential to melt entire ice pack

A warm region of water trapped deep below the surface of the Arctic seas north of Canada has the potential to leave the entire area devoid of ice.

Warming ocean to alter ecosystems and affect fisheries by end of century, says NIWA scientists

Warming ocean to alter ecosystems and affect fisheries by end of century, says NIWA scientists

Rapid warming of the ocean near Tasmania may provide a good indication of how the water around New Zealand will change as the planet warms, say NIWA scientists.

Warmer seas make whales more difficult to find and track

Warmer seas make whales more difficult to find and track

A two-week expedition to tag blue whales in New Zealand waters for the first time, almost came up empty due to warmer sea temperatures causing the animals to change their behaviour.

Five more days from the official hottest summer on record

Five more days from the official hottest summer on record

Over land, Dr Kidson noted that “in none of the four months November [1934] to February [1935] did any station in New Zealand record a mean temperature which was not above normal”.
