World's Strongest Storm in 2020 Makes Landfall in the Philippines

The world's strongest storm this year (2020) repeatedly slammed into the eastern part of the Philippines, bringing "catastrophic violent winds" in what weather experts say is set to be the hardest landfall on record.
Super Typhoon Goni first hit land over Catanduanes province, and subsequently pummeled Albay. It's expected to cross the southern Luzon and Metro Manila area before exiting land, bringing "intense" rain to the capital.
"Catastrophic violent winds and intense to torrential rainfall associated with the region of the eyewall and inner rainbands of the typhoon is prevailing or expected within the next 12 hours.

National Clean Air Programme

According to an analysis of the National Air Quality Monitoring Programme tracking, Chandigarh, Himachal Pradesh and Punjab were the only ones among 23 states and union territories listed in the National Clean Air Programme (NCAP) to have above average readings in the past three years for PM 10.
As per NCAP, 104 readings are required in a year to get an accurate picture.
The list shows Punjab has an average PM 10 reading of 133 over the last three years. Himachal Pradesh stands at 125, and Chandigarh at 102.
This does not necessarily mean that pollution levels have gone down in these states, in fact pollution levels in all three continue to be much higher than acceptable CPCB norms and way above the WHO limits of 10 micrograms/cubic-metre. What these rankings seem to indicate is a trend on air pollution in Chandigarh, Punjab and Himachal Pradesh, and that all three monitor them better than other states in the country.

National Action Plan for Vulture Conservation

The National Action Plan for Vulture Conservation, 2020-25 was approved by National Board for Wild life. The plan suggested that new veterinary non-steroidal anti-inflammatory drugs be tested on vultures before they are commercially released.
The new plan automatically removes veterinary use of a drug if it is found to be toxic to vultures.
Under the plan, every state will host at least one vulture safe zone to conserve the remnant population of vultures in the state. These centres will facilitate conservation and breeding of vultures.
A coordinated Nation-wide vulture counting is to be conducted by the Bombay Natural History Society, Forest Department, non-profit organisations, Research Institute, etc. These countings are to be conducted at regular intervals.

Suture Zone of the Himalayas is Tectonically Active

The study conducted by scientists from Wadia Institute of Himalayan Geology says that the suture zone of the Himalayas has become tectonically active.
The scientists have observed that the thrust is broken, sedimentary beds are tilted. Bedrocks are showing brittle deformation and the rivers are associated with the uplifted terraces. The scientists used the technique of Optically Stimulated Luminescence to make these observations.
The findings say that the Suture Zone of the Himalayas has been active in the recent years of the earth history. This is one of the several reasons for the recent frequent earthquakes in the northern India.
The scientists have estimated it as 78,000 to 58,000 years. According to them, the recent 2010 earthquake of low magnitude 4.0 in the village of Upshi was due to thrust rupture.
Himalayas are made of three thrusts namely Main Central Thrust, Main Frontal Thrust and Main Boundary Thrust. According to the study, Main Frontal Thrusts are locked and the overall deformation is occurring in the Main Frontal Thrust.
The study also says that there is a remote fault zone in the suture zone that is tectonically active.

Japan Set to Target Zero Emissions by 2050

Prime Minister Yoshihide Suga is set to bind Japan to a target for carbon neutrality by 2050, a shift in stance that will bring the country in line with the European Union and more than 60 other nations in efforts to combat climate change.
The move, if confirmed, would make the world's third-largest economy the second Asian country after South Korea to aim for the 2050 target that is considered the minimum needed to keep global average temperatures from rising by more than 1.5 Celsius.
Japan is the world's fifth-biggest emitter of carbon dioxide, the heat trapping gas that scientists say is already causing major heatwaves, bigger and more powerful cyclones and periods of drought around the world.
