NASA eyes intensifying tropical cyclone 'Frances'

NASA eyes intensifying tropical cyclone 'Frances'

Two NASA satellites have provided forecasters in Australia with visible and rainfall data as tropical cyclone 'Frances' strengthened in the western Timor Sea.

NASA's Aqua satellite has captured a visible image of the storm that showed a cloud-filled eye, while the Global Precipitation Measurement Mission or GPM core satellite found heaving rainfall occurring.

Frances formed north of Melville Island, Australia on April 27, 2017.

Frances has been gradually intensifying while moving south-southwestward through the Timor Sea.

Researchers relate extreme weather to global warming

Researchers relate extreme weather to global warming

In the past, scientists typically avoided linking individual weather events to climate change, citing the challenges of teasing apart human influence from the natural variability of the weather. But that is changing.

"Over the past decade, there's been an explosion of research, to the point that we are seeing results released within a few weeks of a major event," said Diffenbaugh, who is also the Kimmelman Family Senior Fellow at the Stanford Woods Institute for the Environment.

More trees, less global warming? Not exactly

More trees, less global warming? Not exactly

Trees are considered as one of our biggest natural allies in the war against global warming, but in a new twist, scientists have found that the army of green is spewing out methane.

The University of Delaware study is one of the first in the world to show that tree trunks in upland forests actually emit methane rather than store it, representing a new, previously unaccounted source of this powerful greenhouse gas.

Methane is about 25 times stronger than carbon dioxide, with some estimates as high as 33 times stronger due to its effects when it is in the atmosphere.

Now, a `greener` way to make vanilla flavouring

Now, a `greener` way to make vanilla flavouring

Today, over 95 percent of vanilla flavouring used in foods, from cereal to ice cream, is not natural and the production of the synthetic one is taking a toll on the environment.

The process of making it synthetically creates a stream of wastewater that requires treatment before it can be released into surface waters.

Now, the researchers have come up with a new "greener" way to make vanillin, the primary flavour compound in vanilla.

Is climate change connected to location, local weather?

Is climate change connected to location, local weather?

Researchers in the United States have found that local experiences and temperatures drive belief or non-belief of people in climate change.

The study, published in the Journal of Proceedings of the National Academy of Sciences, found that Americans' belief that the earth is warming is related to the frequency of weather-related events they experience, suggesting that local changes in their climate influence their acceptance of this worldwide phenomenon.

Rise in methane emissions may hamper efforts to slow climate change

Rise in methane emissions may hamper efforts to slow climate change

A recent research published in the journal Environmental Research Letters highlights that global concentrations of methane, a powerful greenhouse gas and cause of climate change, are now growing faster in the atmosphere than at any other time in the past two decades.

The researchers reported that methane concentrations in the air began to surge around 2007 and grew precipitously in 2014 and 2015. In that two-year period, concentrations shot up by 10 or more parts per billion annually.

Climate data rescue activities being undertaken in Australia

Climate data rescue activities being undertaken in Australia

A new research draws attention to recent data rescue efforts undertaken in Australia to study the climate and climate change, in the southern latitudes.

The article has been published in published in Advances in Atmospheric Science journal.

Long-term weather data is the backbone of almost all research into climate change and variability.

The recovery of historical instrumental data is a well-established practise in the Northern Hemisphere, where observations are available for the past several centuries in many regions.

Competitive male species adapt faster to climate change

Competitive male species adapt faster to climate change

A new study has found that sexually selected species can adapt faster to new environments, and are less likely to go extinct.

According to the study, showy ornaments used by the male of the species in competition for mates, such as the long tail of a peacock or shaggy mane of a lion, could indicate a species' risk of decline in a changing climate.

Ross Sea agreement believes to be biggest deal ever hit to protect marine wildlife

Ross Sea agreement believes to be biggest deal ever hit to protect marine wildlife

The recent international agreement that aims to protect marine wildlife by creating the world’s largest marine reserve in Antarctica is believed to be the biggest deal ever hit to protect the region.

Nearly two dozen nations and the European Union (EU) agreed to establish the world’s largest marine protected area in Antarctica by preventing commercial fishing and other activities in the Ross Sea, which is home to marine creatures like whales, penguins and krill, which are currently threatened by overfishing.

Dealing with climate change is more important than merely adapting to it, says Norway ambassador

Dealing with climate change is more important than merely adapting to it, says Norway ambassador

Norway's Ambassador to India Nils Ragnar Kamsvag recently shared Norway's experience on dealing with climate change at the International Conference on Climate Change, Water, Agriculture and Food Security held in Hyderabad.

Climate change adaptation is important, but dealing with climate change is more important. We have to try to limit the climate change and take radical steps internationally, stated Ambassador Kamsvag in his opening remarks at the conference.
