A recent study by Alessandra Giannini confirms a strong link between sea surface temperatures and precipitation in Africa's Sahel region. The research finds that Indian Ocean temperatures are the primary driver of precipitation in the area, with implications for climate prediction and seasonal predictions.
NASA satellites sample critical 'ingredients' to predict hurricane formation, including sea surface temperature of at least 82 F, rotating winds, air temperature, and humidity. The data helps forecasters determine storm strength, location, and tracks.
Research reveals that intense atmospheric jets triggered by strong winds can drive convection in the North Atlantic Ocean. This process increases the number of convection sites from two to three, significantly impacting the Atlantic climatic system.
Research by West and Salm reveals that factors such as local upwellings of cold water and diverse coral populations can protect coral reefs from bleaching. Additionally, corals emerging at low tides may be more tolerant of heat stress, with examples seen in Palau's Rock Islands.
A new study uses tree ring chronologies to identify patterns of multidecadal oscillations in precipitation, linking them to ocean temperature shifts. The research suggests that the Great Plains, Rockies, and Southwest are prone to megadroughts when tropical Pacific and North Atlantic sea surface temperatures align.
Scientists studying the western Pacific Ocean find regional changes in saltiness correspond to changes in upper ocean heat content before an El Nino event. Observing salinity improves predictions, suggesting a lag time of six to 12 months for modifications in ocean layers.
A recent study by Texas A&M University researchers suggests that natural climate variability may contribute up to half of the observed global surface warming since the 1970s. The analysis of ocean surface temperature records in the tropical Pacific indicates that long-term changes in ocean temperatures precede global air temperature ch...
The Terra satellite provides daily global measurements of sea surface temperature accurate to within half a degree, surpassing previous satellites' accuracy. This high-resolution data enables scientists to better understand climate change and its effects on the ocean's temperature.
A new method significantly improves U.S. seasonal forecast accuracy by analyzing changes in sea surface temperatures across various ocean basins. The approach raises the bar for seasonal and inter-annual climate forecasts, with increases in predictability noted during spring and summer months.
Scientists found that warmer surface temperatures can splinter an ice shelf and prime it for a major collapse. The process is triggered by the added pressure from surface water filling crevasses, which can crack the ice entirely through.
A new study reveals that warmer surface temperatures during summers can cause ice shelves to collapse, leading to increased ice flow and sea-level rise. The research found that added pressure from meltwater can crack ice shelves, causing portions to float away and eventually melt.
A study by NASA researchers found that the eastern U.S. has cooled by 0.1° Celsius per decade, contrasting with global warming. The researchers attribute this cooling to increased cloud cover caused by warmer ocean temperatures in the Pacific.
A new study documents very warm sea surface temperatures in the western Pacific about 400,000 years ago, which supports the hypothesis that the tropics is a key player in global climate change. The analysis provides valuable insights into past temperature shifts and could aid numerical modelers in predicting future warming.
A study using satellite instruments reveals that the atmosphere has gotten warmer and wetter over the past decade. Water vapor levels in the atmosphere have increased by 2%, indicating a significant change in climate dynamics.
Microorganisms can survive deep underground due to high temperatures, availability of water and chemical nutrients, porosity of the surrounding rock, and flow of fluids. Subsurface scientists have identified these factors to understand how extremophiles colonize environments and potentially shed light on life on other planets.
Scientists have found that sea surface temperatures in Atlantic, Pacific, and Western Pacific oceans significantly impact rainfall patterns in the Amazon. Sea surface temperatures play a crucial role in predicting drought or floods in the region.
Researchers used a computer climate model to find that vegetation interactions significantly drive the Sahel region's drought. The study suggests that natural vegetation causes enhanced drying, leading to cooler climates and reduced rainfall.
A CU study of ice-age sediment cores found that temperature fluctuations in the warm Atlantic Ocean were as large as those seen during the last ice age, raising concerns about future climate change. The research suggests that human-induced changes to ocean circulation could trigger global climate impacts.
Research indicates the Indian Ocean has its own El Niño-like phenomenon characterized by an east-to-west oscillation of warm waters affecting other parts of the world. The study found significant warming of the western portion of the Indian Ocean in 16 out of 48 years between 1950 and 1998, but only three were active El Niño years.

The US Navy has developed a new hot water suit with a layer of foam containing bits of wax inside tiny plastic beads to prevent heat loss in cold ocean depths. The wax absorbs warmth from the diver's body and melts, then freezes in icy waters, radiating latent heat back to the diver.
Researchers at Columbia University have found a link between the greenhouse effect and warmer winters in the northern hemisphere. They used a NASA model to suggest that increased greenhouse gases are causing stronger winds to carry warmer air from oceans to continents, leading to colder continental air near the oceans.
Scientists attribute the retreats to regional warming trends, which have caused annual melt seasons to increase by two to three weeks over the last 20 years. The ice shelves' disintegration is accelerating, with much of the Wilkins Ice Shelf likely gone within a few years.
A Dartmouth physicist has discovered that applying a small electric voltage across an ice-metal interface can break the bond between ice and metal surfaces, potentially preventing or reducing icing on airplane wings. The effect of the voltage can be reversed to increase ice adhesion, which could improve traction on icy roads.
Recent data from NASA's Galileo spacecraft suggests that Jupiter's moon Europa may have a slushy ocean beneath its icy surface, with evidence including shallow impact craters and gaps in the ice. The findings support the idea that warmth from tidal forces could be keeping parts of the ocean liquid.
Researchers at the University of Illinois found a correlation between Pacific Ocean sea-surface temperatures and precipitation rates in the Great Plains. Warmer ocean temperatures lead to increased storm activity, resulting in wetter weather.
A team of NASA scientists disagrees with a recent study suggesting that satellite data shows no warming trend in the Earth's lower atmosphere, while surface temperature data shows a +0.12 deg C/decade increase. The disagreement is largely due to differences between satellite and surface measurements over oceans versus land areas.
Research from NASA and the Global Hydrology and Climate Center suggests that the temperature structure of the atmosphere is more complex than previously thought. The study found a slight downward trend in the lower troposphere since 1979, while surface measurements show a warming trend.
A new remote imaging technique has given scientists a promising way to better understand breaking waves in the open ocean. The technique measures temperature changes in the 'skin-layer' of the ocean, detecting warmer water mixed up to the surface after a wave breaks.
