Heatwave-related death rates will take high numbers by 2080, according to a new study released Tuesday. The number of people dying from severe heatwaves is likely to increase steadily in tropical and subtropical regions if we fail to adapt to future climate temperatures.

A global new Monash-led study is the first to project upcoming heatwave-related deaths. It aimed at helping policymakers in taking steps to adapt to and mitigate the negative effects of rising greenhouse gas emissions and plan strategies to handle climate change.

“Future heatwaves in particular will be more frequent, more intense and will last much longer,” said Associate Professor Guo.

Published today in PLOS Medicine, the study recommends reducing greenhouse gas emissions at a high level to decrease future deaths related to heatwaves.

The study analyzed data from 412 communities across 20 different countries and regions including North, South, and Central America to Europe, Asia, and Oceania. Researchers estimated potential death rates related to heatwaves for the period of 2031 to 2080.

Researchers found that under the extreme scenario with no adaptation to climate change, the expected heatwave-related deaths in the Philippines would 12 times increase in 2031 to 2080 compared to the period 1971 to 2020.

European countries and the United States could face a smaller increase in deaths from heatwaves, while Britain will see four times more excess deaths under the same scenario.

“If the Australia government cannot put effort into reducing the impacts of heatwaves, more people will die because of heatwaves in the future,” Associate Professor Guo warned.

Great Barrier Reef suffers 5th near-death experience in 30,000 years, which showed it an each sort of rises in the sea level, increasing sediment and changing temperature.

More acidic and warmer ocean under severe stress, the Great Barrier Reef in Australia has just got a sixth life since the past 30,000 years after experiencing a near-extinction event for fifth time in the period, which indicates that the reef is very much resilient than ever thought, as reported by associated researchers on Monday.

The research team determined by analyzing the fossil data obtained from the cores drilled in the 16 sites of the ocean floor that Great Barrier Reef was capable of migrating from 20 centimeters (i.e. 7.9 inches) to 5 meters a year.

During the investigation, the team found that the reef has had ever suffered through two ubiquitous occurrences because of the exposure with air nearly 22,000 and 30,000 years back, so that the reef shifted towards the sea in order to survive. later, two more near-extinction conditioned were faced by the reef because of rapidly rising sea level as about 13,000 and 17,000 years ago, after which the reef shifted backward to the land.

Co-authored of the paper published in the Nature Geoscience journal, Jody Webster from the University of Sydney said in a statement that, “I have grave concerns about the ability of the reef in its current form to survive the pace of change caused by the many current stresses and those projected into the near future.”

Russia launches floating power plant with “Nuclear Titanic” making its way towards Arctic region and hopefully the FNPP technology will also interest other South Asian countries in an attempt of building extra seawater desalination facilities.

Russia’s state nuclear corporation Rosatom launched the world’s first “floating” nuclear power plant (FNPP) over the weekend. The advancement is another example of the Kremlin’s move in expanding its presence in the Arctic port.

The power plant called “Akademik Lomonosov” will be floating through the Baltic Sea before arriving at the Murmansk base where it will receive the nuclear fuel. Akademik Lomonosov was towed out of a shipyard in St. Petersburg on April 28, 2018, where it was built.

However, environmentalist groups are not motivated by the likelihood of a nuclear power plant being sent to the Arctic because it can cause a high damage if something went wrong. According to Greenpeace, which recently warned of a “Chernobyl on ice,” the plan is a big environmental risk.

Nuclear expert Jan Haverkamp said, “Nuclear reactors bobbing around the Arctic Ocean will pose a shockingly obvious threat to a fragile environment which is already under enormous pressure from climate change.” “This hazardous venture is not just a threat to the Arctic, but, potentially, to other densely populated or vulnerable natural regions too,” Haverkamp added.

Rosatom said that they believe the floating nuclear power plant occur sometime in 2019. It also said that FNPPs are designed with the great scope of safety and to keep uninterruptible power and huge desalinated water supply in different remote areas.
