California’s new law to target short-lived climate pollutants to combat impacts of climate change

Californiaa is strengthening laws to prevent impacts of climate change
California is strengthening its steps to fight climate change. A new legislation has been signed Monday by Governor Jerry Brown as per which the state will regulate greenhouse-gas emissions linked to dairy and landfills.

Under the new law, a category of gases - short-lived climate pollutants showing significant impacts of climate change, has been included. The new law requires significant decline in different pollutants, including methane, HFC gases and soot.

Sea ice in Arctic reaches its second-lowest level this summer

Sea ice in Arctic reaches its second-lowest point this summer

After 2012 when the record for lowest level of sea ice floating on the Arctic Ocean was made, this summer Arctic has witnessed its second-lowest level. Experts have been calling the new pattern for ice activity in the Arctic as a new regime.

Mark Serreze, director of the National Snow and Ice Data Center in Colorado said that the new findings are strengthening the statement that the Arctic acts as the early warning system for impacts of climate change.

6000-year-old fabric found in Peru indicates dyeing of textiles with Indigo: Research

6000-year-old fabric found in Peru indicates dyeing of textiles with Indigo: Research

Discovery of the oldest indigo-dyed fabric from Peru has pushed back the earliest use of indigo by 1,500 years. Around 6,000 years back, the blue indigo dye was used by pre-Hispanic communities in Peru.

The findings published in Science Advances are based on the assessment of blue pigment a piece of cotton fabric found at an archaeological site in Huaca Prieta, Peru. With the use of highly sensitive equipment known as high-performance liquid chromatography, the researchers were able to know the source of blue pigment.

Arctic sea ice shrinks to second-lowest extent this month since satellite observations started

The National Snow and Ice Data Center has announced that Arctic sea ice witnessed its second-lowest level this month since the time satellite observations have started. The center said that the area, which used to be covered by at least 15% of the sea surface with ice, has reduced to the year’s low point of 4.14 million square kilometers on Saturday.

Very-low possibility of La Niña occurrence this fall and winter: NOAA

Very-low possibility of La Niña occurrence this fall and winter: NOAA

A NOAA report states that there very few chances that La Niña conditions will develop this fall or winter. There are 55 to 60% chance that neutral condition will be in place this fall and winter, said the NOAA. Owing to it, the agency has cancelled its La Niña watch as well.

It is not a unique phenomenon, said the researchers, as it can happen and has in the past as well. La Niña/El Niño are basically the periodic cooling and warming of the eastern and central Pacific Ocean. The last winter witnessed a strong El Niño.

New, complex model suggests Sakurajima volcano could erupt catastrophically in next 25-30 years

New, complex model suggests Sakurajima volcano could erupt catastrophically in next 25-30 years

Researchers have warned that Sakurajima volcano, a Japanese volcano, could erupt in a disaster manner in the next 25-30 years. Last time, the volcano erupted in 1914 and as per the researchers the liquid magma is growing beneath the volcano every year.

Study’s co-researcher James Hickey from the University of Exeter's Camborne School of Mines in England, said that the volcano’s reservoir is expanding at a fast pace. From the current analysis, scientists would be better positioned to predict when other big-sized volcanoes could erupt.

Three-year coral reef airborne lab mission to solve problems related to coral’s health

A project head by NASA is underway that aims to find out mysteries regarding what factors drive coral reef health. The data from the study could help experts have better information to tackle the problem efficiently.

August 2016 ties with July for warmest month ever recorded: NASA

August 2016 ties with July for warmest month ever recorded: NASA

August 2016 was the hottest August since the time record-keeping started in the 1880s, unveiled NASA in a report. As per different sources, August was 1.8 degrees Fahrenheit hotter than average August temperature from 1951 to 1980.

The study has also unveiled that the August 2016 global temperature has tied with July to bear the tag of the warmest month ever recorded. NASA said that August has been marked as the 11th continuous month in which average temperature records were broken.

Wilderness area twice the size of Alaska lost in last 20 years: Study

Wilderness area twice the size of Alaska lost in last 20 years: Study

An alarming revelation has been made in a research paper that since the 1990s around a tenth of earth’s wilderness has been lost. Human activity and disturbance have been reducing these natural spots on an annual basis and this will impact habitat of many wild species.

Scientists from the Wildlife Conservation Society have reached the conclusion after assessing satellite and survey data dating back to the 1990s. From the assessment, the researchers have come to know that across the globe, area twice the size of Alaska has been lost in the last two decades.

Climate change results into Hawaiian forest birds’ die-offs

Climate change results into Hawaiian forest birds’ die-offs

A journal Science Advances-published research paper has provided yet another evidence of how climate change is altering earth. Study researchers have found that a drop has come in the population of native forest birds on the Hawaiian island of Kauai. They also face the threat of extinction because of climate change.

The climate change is heating the birds’ habitat and allows thriving and spread of mosquito-borne diseases. Global warming increases temperature resulting into the spread of diseases like avian malaria in wooded areas.
