India – More flooding has struck in the state Assam in north eastern India, affecting over 300,000 people in 13 districts. Disaster authorities in the state now report a third wave of flooding after days of heavy rainfall from around 22 September. Heavy rain also affected the neighbouring state of Meghalaya where 13 people have lost their lives in flooding and landslides. In Assam, the State Disaster Management Authority (ASDMA) reports that 1 person has died and 317,977 people in 389 villages across 13 districts have been affected by the recent wave of floods.

Global Warming

Warming Oceans More ‘Stable’ And That’s Bad, Scientists Warn

Global warming is making the oceans more stable, increasing surface temperatures and reducing the carbon they can absorb, according to research published Monday by climate scientists who warned that the findings have “profound and troubling” implications.

Man-made climate change has increased surface temperatures across the planet, leading to atmospheric instability and amplifying extreme weather events, such as storms.

But in the oceans, higher temperatures have a different effect, slowing the mixing between the warming surface and the cooler, oxygen-rich waters below, researchers said.

This ocean “stratification” means less deep water is rising towards the surface carrying oxygen and nutrients, while the water at the surface absorbs less atmospheric carbon dioxide to bury at depth.

Most of this stabilisation occurred towards the surface and was attributed largely to temperature rises.

They said this process is also exacerbated by the melting of sea ice, meaning that more freshwater – which is lighter than saltwater – also accumulates on the surface of the ocean.

This seemingly technical finding has profound and troubling implications. These include potentially driving more “intense, destructive hurricanes” as ocean surfaces warm. A reduction in the amount of CO2 absorbed, which could mean that carbon pollution builds up faster than expected in the atmosphere.

With warmer upper waters receiving less oxygen, there are also severe adverse implications for marine life.

Wildfires

Wildfires – California, USA

Thousands of fire-sapped California residents were forced to flee a pair of new blazes on Monday that have killed at least three people, torched nearly 70,000 acres and prompted a state of emergency in three counties.

The breakneck Zogg Fire had burned through 31,200 acres near Redding in Northern California, while the Glass Fire had charred more than 36,200 acres in the Napa and Sonoma wine country north of San Francisco, according to Cal Fire. Both fires were at 0% containment as of Monday night.

The fires, driven by gusty winds, burned several structures on Sunday night into Monday morning, including homes in Santa Rosa, as well as the Chateau Boswell winery and the nearby Black Rock Inn in the Napa County town of St. Helena. The area contains more than five dozen wineries.
