Monsoon woes

When is India prone to flooding?
What is the main cause of flooding in India?
Who are affected by the flooding? 
Flooding in India on the onset of the SW Monsoon  killed dozens and displaced thousands at the start of July 2019.



Look at how the flood as a results of the monsoon killed 324 and displaced more than 200,000 in Aug last year (2018)

India experiencing SW Monsoon in July which brings heavy rain as the onshore wind crosses the Indian ocean.

The NE Monsoon is an offshore wind and bring little or no rain to India.

The flooding caused by the monsoon has led to widespread damage and deaths in India.
The southern state of Kerala, a tourist haven known for its beaches, hill resorts and backwaters, has been the worst hit region for the second consecutive year, forcing the closure of the Kochi international airport for three days last week.At least 76 people have died, 58 are missing and another 32 have received injuries in Kerala.
Around 288,000 people across the state's worst affected districts including Wayanad, Malappuram and Kozhikode have been moved to relief camps.At least 42 people have also lost their lives and 580,000 people evacuated in neighbouring Karnataka state.
There were 66 deaths in the western states of Maharashtra and Gujarat, with tens of thousands of people shifted to relief camps.

Climate change affecting Singapore

How does climate change affects Singapore?

https://www.straitstimes.com/singapore/how-vulnerable-is-spore-to-climate-change


In recent years, days when maximum temperatures exceed 34 deg C and nights when minimum temperatures exceed 26 deg C have been more frequent in Singapore. It is also projected that average temperature in Singapore  will increase between 1.4 deg C and 4.6 deg C, as well as more frequent warmer days and nights by 2100.

These temperature changes are due to larger-scale greenhouse gas emissions (GHG) and Singapore's urbanisation. Replacing Singapore's natural forests and mangroves with buildings and other infrastructure results in built-up surfaces  producing more heat. At night, the difference between downtown Singapore and forests in Lim Chu Kang can exceed 7 deg C.

One of most severe impacts of climate change in Singapore will be the increase in sea level. The average sea level around Singapore's coasts has risen steadily at a rate of between 1.2mm and 1.7mm per year, and is projected to increase to about 1m by 2100.

Singapore carbon tax of $5 per tonne of GHG emissions implemented this year will encourage more efficient use of non-renewable energy. The carbon tax revenues will also be used for renewable energy innovations and transformation of emission-intensive local industries.

Other than the above read the article below on other ways we can mitigate the impacts of climate change in Singapore.

New update 25 Aug

Possible approaches dealing with sea level rise:

  1. Flood-proofing existing buildings and infrastructure, or designating areas that would be allowed to flood during high tide.
  2. Removal and reallocation of key infrastructure and assets to areas that the sea cannot inundate.
  3. Planting and managing mangrove coasts, or engineered options like sea walls, land reclamation and polders.

How does preparedness measures such as building earthquake resistant buildings help to mitigate the impacts of earthquake?

What are the limitations of preparedness measures?
