New NASA Study Shows Historical Records Miss a Fifth of Global Warming

New research led by NASA scientists reveals that almost one-fifth of the global warming that has occurred in the past 150 years has been missed by historical records due to quirks in how global temperatures were recorded. The study explains why projections of future climate based solely on historical records estimate lower rates of warming […]

New Study Shows Long-Term Global Warming Needs External Drivers

New research from NASA and Duke University provides new evidence that natural cycles alone aren’t sufficient to explain the global atmospheric warming observed over the last century. A study by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, and Duke University in Durham, North Carolina, shows, in detail, the reason why global temperatures remain […]

NASA Details Record-Shattering Global Warm Temperatures from 2015

&nbs According to independent analyses by NASA and the National Oceanic and Atmospheric Administration, Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880. Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been […]

Study Shows Greenland Ice Sheet Movement Decreasing Despite Warming

A newly published study from the University of Edinburgh shows that the movement of the southwest portion of the Greenland Ice Sheet that terminates on land has been slowing down despite decades of increasing temperatures and surface melting. The study is published in the journal Nature. Researchers derived their results by tracking ice sheet movement […]

Stimulating Ocean Phytoplankton Growth to Reduce Global Warming

In a newly published study, scientists from MIT reveal unintended consequences of an idea to stimulate ocean phytoplankton growth in order to geoengineer a cooler atmosphere. Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon […]

July 2015 The Warmest Month Ever Recorded

A new report from the National Oceanic and Atmospheric Administration reveals that July 2015 had the all-time highest monthly temperature in the 1880–2015 record, at 61.86°F (16.61°C), surpassing the previous record set in 1998 by 0.14°F (0.08°C). Global highlights: July 2015 The July average temperature across global land and ocean surfaces was 1.46°F (0.81°C) above […]

New Research Shows Greenland’s Undercut Glaciers Melting Faster than Thought

In a newly published study, a team of researchers reveal that Greenland’s glaciers are likely melting faster than previously thought. Greenland’s glaciers flowing into the ocean are grounded deeper below sea level than previously measured, allowing intruding ocean water to badly undercut the glacier faces. That process will raise sea levels around the world much […]

Oceans Temporarily Hide Global Warming

A newly published NASA study shows that the recent extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans, accounting for the slowdown in the global surface temperature trend observed during the past decade. Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory (JPL), […]

Demise of Laurentide Ice Sheet Due to Sudden Shift in “Radiative Forcing”

June 23, 2015

0 Comments

A study of the demise of the Laurentide Ice Sheet that once covered Canada may help scientists better understand shrinking ice fields today - like this melting ice margin in Greenland.

Researchers at Oregon State University studied the cause of the demise of the massive Laurentide Ice Sheet during the last ice age, looking for clues as to how a warming climate may impact ice sheets on Greenland and Antarctica. A new study has found that the massive Laurentide ice sheet that covered Canada during the […]

Detailed Global Climate Change Projections

A new dataset from the NASA Earth Exchange shows how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth’s atmosphere. The dataset, which is available to the public, shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon […]

Some Fossil Fuels Must Remain in the Ground to Limit Global Warming

New research led by the University College London shows that a third of oil reserves, half of gas reserves and over 80% of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target agreed by policy makers. The study funded […]

MIT Reveals Missing Piece of the Climate Puzzle

In a newly published study, MIT researchers show that a canonical view of global warming tells only half the story and reveal the missing piece of the climate puzzle. In classrooms and everyday conversation, explanations of global warming hinge on the greenhouse gas effect. In short, climate depends on the balance between two different kinds […]

Human Contribution to Glacier Mass Loss Has Steadily Increased

By using computer simulations of the climate, researchers have found evidence for anthropogenic glacier mass loss in recent decades. In a paper published in the journal Science, the team reports that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes and that the […]

As Climate Changes Boreal Forests to Shift North

New climate change research from the Berkeley Lab suggests that boreal forests will likely shift north and will relinquish more trapped carbon than most current climate models predict. It’s difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area’s vegetation? New […]

A new analysis finds that swift action by politicians is the single most important factor in limiting global warming. The costs of delays outweigh any possible benefits of waiting for more scientific research into the mechanisms of climate change. The scientists published their findings in two studies in the journal Nature ¹ ². This contradicts […]

Northern exposure, aggressive snowmaking and hard manmade snow crystals are helping some of the bigger ski resorts deal with climate change, but smaller operations are under threat as the warmer winters will lead to less snow on the ground. The scientists published their findings in the journal Tourism Management. Regional operations at lower elevations that […]

Colder temperatures have kept crabs out of Antarctic seas for 30 million years, but warmer waters from the ocean depths are now intruding onto the continental shelf, and this seems to be changing the delicate ecological balance. An analysis¹ has suggested that 1.5 million crabs already inhabit Palmer Deep, an ocean floor valley. Native organisms […]
