What is cljmate eruption change in india
Answers
The continents we see today were formed when the landmass began gradually drifting apart, millions of years back.
Volcanoes
When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Although the volcanic activity may last only a few days, yet the large volumes of gases and ash can influence climatic patterns for years. The gases and dust particles partially block the incoming rays of the sun, leading to cooling.
To better understand the risks of climate change to development, the World Bank Group commissioned the Potsdam Institute for Climate Impact Research and Climate Analytics to look at the likely impacts of temperature increases from 2ºC to 4ºC in three regions. The scientists used the best available evidence and supplemented it with advanced computer simulations to arrive at likely impacts on agriculture, water resources, cities and coastal ecosystems in South Asia, South East Asia and Sub-Saharan Africa. Some of their findings for India include:
Extreme Heat
What we know
India is already experiencing a warming climate.
What could happen
Unusual and unprecedented spells of hot weather are expected to occur far more frequently and cover much larger areas.
Under 4°C warming, the west coast and southern India are projected to shift to new, high-temperature climatic regimes with significant impacts on agriculture.
What can be done
With built-up urban areas rapidly becoming “heat-islands”, urban planners will need to adopt measures to counteract this effect.
Changing Rainfall Patterns
What we know
A decline in monsoon rainfall since the 1950s has already been observed. The frequency of heavy rainfall events has also increased.
What could happen
A 2°C rise in the world’s average temperatures will make India’s summer monsoon highly unpredictable.
At 4°C warming, an extremely wet monsoon that currently has a chance of occurring only once in 100 years is projected to occur every 10 years by the end of the century.
An abrupt change in the monsoon could precipitate a major crisis, triggering more frequent droughts as well as greater flooding in large parts of India.
India’s northwest coast to the south eastern coastal region could see higher than average rainfall.
Dry years are expected to be drier and wet years wetter.
What can be done
Improvements in hydro-meteorological systems for weather forecasting and the installation of flood warning systems can help people move out of harm’s way before a weather-related disaster strikes.
Building codes will need to be enforced to ensure that homes and infrastructure are not at risk.
