Ice water mix helps body to cope up exertion in hot weather

Washington D.C. [USA], Oct. 20 : Temperature of water consumed may be as important as the amount when trying to manage thermoregulation, indicated new report.

The study from the University of Montana demonstrated a unique relationship between fluid volume and fluid temperature during arduous work in the heat.

It indicated that an ice slurry/water mixture was as effective as ambient water even when consumed in half the quantity. Investigators also emphasized the importance of rest.

"While the common approach to managing health in hot environments centers around maintaining hydration, limited attention is devoted to managing heat production from hard work or play," explained lead investigator Brent C. Ruby.

U.S.: Hurricane Matthew claims 10 lives, marks 'record-breaking' flooding

Washington D. C. [United States], Oct. 9 - At least ten people have been killed by Hurricane Matthew in different regions in the United States.

Authorities claim that three people have died in North Carolina, four in Florida and three people were killed in Georgia, including a man when a tree fell on his house.

The storm has left behind record-breaking flooding on Saturday, as the center of the storm moved out into the Atlantic Ocean, dragging bands of heavy rain with it across eastern North Carolina, reports the CNN.

According to the National Hurricane Center, "This rainfall is leading to record-breaking flooding over portions of eastern North Carolina, and it may result in life-threatening flooding and flash flooding elsewhere across the region,"

Modern day Indian Ocean Monsoon system's abrupt onset

Washington D.C, Jul 30 - A team of researchers has pinpointed the abrupt onset of modern day Indian Ocean Monsoon system, offering some clues to future climate changes and sea-level rise.

Their study revealed the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its connection to past climate changes and coral reefs in the region. The analysis of sediment cores provides direct physical evidence of the environmental conditions that sparked the monsoon conditions that exist today around the low-lying island nation and the Indian subcontinent.

Study claims Antartic birds can recognise individuals

Washington D. C., Mar. 26 : Just like crows, magpies and mockingbirds, brown skuas living in Antarctica can also recognise individual people.

Scientists in South Korea studied brown skuas living in Antarctica and reported that these birds too recognise the people, who had previously accessed the nests to measure their eggs and nestlings.

Researcher Yeong-Deok Han said that he had to defend himself against the skuas' attack, adding the birds flew over him and tried to hit him when he was with other researchers. Even when he changed his field clothes, they followed him. The birds seemed to know him no matter what he wore.

Explosive volcanism drove major changes in 'Snowball Earth'

Washington D. C., Jan. 19 - According to a new research, around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this 'Snowball Earth'.

Many aspects of this extreme glaciation remain uncertain, but it is widely thought that the breakup of the supercontinent Rodinia resulted in increased river discharge into the ocean. This changed ocean chemistry and reduced atmospheric CO2 levels, which increased global ice coverage and propelled Earth into severe icehouse conditions.

The Southampton-led research now offers an explanation for these major changes in ocean chemistry.

Sea levels rising at more rapid rate, fear scientists

Washington D. C., Jan. 5 - A new study has found that Greenland ice sheet due to climate change is rapidly losing the ability to buffer its contribution to the rising sea levelS.

Research undertaken by scholars at the York University researchers has found that an extreme melt that occurred in 2012 caused a layer of solid ice, several meters thick, to form on top of the porous firn in the low elevation areas of the ice sheet.

Professor William Colgan, the study's co-author, said that meltwater couldn't penetrate vertically through the solid ice layer in subsequent years and instead drained along the ice sheet surface toward the ocean.

Going vegan can actually `harm` the environment!

Washington D.C, Dec 15 - Contrary to claims by vegetarians and the activist groups that promote their world view and actor Arnold Schwarzenegger's speech at the United Nations climate talks in Paris, eating a vegetarian diet could actually add to climate change.

As per the new Carnegie Mellon University research, following the USDA recommendations to consume more fruits, vegetables, dairy and seafood is more harmful to the environment because those foods have relatively high resource uses and greenhouse gas (GHG) emissions per calorie.

The study measured the changes in energy use, blue water footprint and GHG emissions associated with U.S. food consumption patterns.

`Modern birds` result of Earth's geography

Washington D. C, Dec. 13 - The power of flight gives birds the edge over most other creatures. Evolution of birds is thought to have begun in the Jurassic Period, and now scientists believe that the Avian evolution is greatly shaped by the history of our planet's geography and climate.

A new research led by the American Museum of Natural History reveals the DNA-based work finds that birds arose in what is now, South America, around 90 million years ago.

They had radiated extensively around the time of the Cretaceous-Paleogene extinction event that killed off the non-avian dinosaurs.

We may face worse climate outlook if actions not taken

Washington D. C, Dec 10 - Climate outlook may be worse than feared, according to a new global study.

As world leaders hold climate talks in Paris, the University of Edinburgh research showed that land surface temperatures may rise by an average of almost 8C by 2100, if significant efforts are not made to counteract climate change.

Such a rise would have a devastating impact on life on Earth. It would place billions of people at risk from extreme temperatures, flooding, regional drought, and food shortages.

Global plant growth not keeping pace with CO2 emissions

Washington D.C, Dec 8 - Global plant growth is not keeping up with the CO2 emissions, according to a new study that suggests reevaluating global carbon emissions targets.

Because plants need carbon dioxide to grow, scientists have expected rising atmospheric CO2 to substantially enhance plant growth, offsetting a portion of human CO2 emissions and, in turn, slowing climate change. However, the research from the Institute on the Environment adds to a growing body of research challenging this expectation.

The study, led by William Kolby Smith, found that global plant growth has indeed increased over the past 30 years, but not as much as expected given the change in atmospheric CO2 concentrations.

Rapid CO2 emissions growth stalls

Washington D. C, Nov 26 - The growth of global carbon emissions has stalled after a decade of rising rapidly, a new study points out just days before Paris climate talks.

After a decade of rapid growth in global CO2 emissions, which increased at an average annual rate of 4 percent, much smaller increases were registered in 2012 (0.8 percent), 2013 (1.5 percent) and 2014 (0.5 percent). In 2014, when the emissions growth was almost at a standstill, the world's economy continued to grow by 3 percent.

Climate change can move mountains, literally!

Washington D.C, Nov 6 - A new study has revealed that local and global changes in the climate have the ability to revamp a mountain's topography.

For millions of years, global climate change has altered the structure and internal movement of mountain ranges, but the resulting glacial development and erosion can in turn change a mountain's local climate. The degree of this cause-and-effect relationship has never been clearly observed, until now.

Moody people may be most adaptable

Washington D.C, Nov 4 - Moody individuals may be just very good at adapting, according to a recent study.

The new theory argues that mood draws on experiences and can, in fact, help us quickly adapt to changes in our environment. For example, experiencing unexpected gains on the stock market should improve a trader's mood. That positive mood may then cause the trader to take more risks, essentially helping her adapt more quickly to a market that is generally on the rise.

Increase in Antarctic snow is greater than losses: NASA

Washington D.C., Oct. 31 - A new NASA study has revealed that the mass gains of Antarctic Ice Sheet is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The new study showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.

Lead author Jay Zwally of the NASA Goddard Space Flight Center believes that it might only take a few decades for Antarctica's growth to reverse.
