After US, rising sea level may soon gobble up an entire island in Canada (downtoearth)

Lennox Island, on the east coast of Canada, is drastically changing its character as the place has started seeing warmer winter and rising sea level. Between 1880 and 2015, the area of the island shrunk from 1,520 acres to 1,100 acres, indicating more than 300 football fields worth of land have been gobbled up by the sea within the span of a few generations. While the island is experiencing fiercer and more frequent storms, the warmer winters are gnawing at the ice cover that has traditionally protected the shores for months.

Is the Canadian island going to suffer the same fate as the vanishing island in Louisiana in the US? The possibility can’t be ruled out.

Layers of concern

It is to be noted that Lennox Island is vulnerable to coastal erosion because it’s made of sand and sandstone and lacks hard bedrock. In this low-lying island, sacred burial grounds have started getting washed away and baseball courts are already under the water. Homes, which were once comfortably elevated, now look dangerously close to the sea.

Every year, the Lennox Island is losing about a hectare (2.47 acres), indicating what impact climate change could have around the world in future. According to Adam Fenech, director of the Climate Research Lab at the University of Prince Edward Island, sea levels could rise as much as three metres in the next 50 years. If that happens, half of the island could come under water.

On average, the Lennox Island is just four metres above sea level. However, it is eroding twice as fast as the rest of Prince Edward Island. This low-lying island is known for growing blueberries and the region has a sacred value to the Mi'kmaq community.

Climate change denial persists in Canada with the previous government pulling out of the Kyoto protocol in 2011. While the rest of the country continues to debate the need for climate action, this community has already commissioned a series of computer simulations to understand the full impact of climate change on their land.

They have started weighing different options to determine how best to save the island. As a last resort, the community is exploring the possibility of developing a few pieces of property on Prince Edward Island.

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...

"ISRO has capabilities to build geostationary satellites for air quality monitoring” (downtoearth)

Pawan Gupta's findings on trans-boundary movement of pollution (Punjab to Delhi) from biomass burning in 2015 spurred debates. He participated in discussions with Indian regulators early September at the Better Air Quality Conference in Busan on the advantages of using satellite data for air quality monitoring. He explains to Down to Earth how air quality monitoring is done using satellite data. How is satellite data used to measure air pollution? Satellites that provide information on atmospheric pollutants are normally (not always) in the low earth orbits (400-1000 km above the Earth’s surface). A single satellite can carry one or more remote sensing instruments onboard that look down to earth and obtain information about the object in the field of view of satellite sensor. The Earth receives electromagnetic radiation from the sun, which travels through space and reaches the earth-atmosphere system. The radiation then interacts with the Earth’s atmosphere and the surface...

What's ailing Namami Gange programme?(DTE)

Winters are extremely hectic for Sushma Patel, a vegetable grower in Uttar Pradesh’s Chunar town. Her farm is in the fertile plains of Ganga where people grow three crops a year. But this is the only season when she can grow vegetables. And before that, she needs to manually dig out shreds of plastic and wrappers from her one-hectare (ha) farm. “This is all because of the nullah,” she says, pointing at an open drain that runs through her field, carrying sewage from the neighbourhood to the Ganga. “Every monsoon, the drain overflows and inundates the field with a thick, black sludge and plastic debris. We cannot even go near the field as the stench of sewage fills the air,” she says. But Patel has no one to complain to as this is the way of life for most people in this ancient town. About 70 per cent of the people in Chunar depend on toilets that have on-site sanitation, such as septic tanks and pits. In the absence of a proper disposal or management system, people simply dump the faec...
