A recent IPCC report sounded a red warning and was released by the strongest warning on climate change.
It is said that the Indian Ocean is warming at a higher level than the other ocean.
Toi break it down because you have a lot of Indian Ocean warmed? The Indian Ocean has warmed up faster than the global average.
The surface temperature of the tropical Indian Ocean rose at an average of 1 ° C during 1951-2015, compared with the global average of 0.7 ° C.
The Indian Ocean was not the only samudera that was faster than the global average – the equatoric Pacific Ocean West too.
Why does the Indian Ocean warm up faster than the global average? The tropical ocean gets a lot of heat, according to the Panickal Swapna, scientists at the Indian Tropical Meteorology Institute.
And in the case of the Indian Ocean, the mainland water body to the north – by South Asian Mass – causes heat to accumulate in the north.
In comparison, the Atlantic Ocean is open to the North Pole area that allows heat to disappear into cooler waters.
Another reason might occur: circulation of southwest monsoon, which plays a role in directing the heat of the North Indian Ocean to the south, has weakened in the past few decades.
It might have allowed more heat to accumulate in the North Indian Ocean.
Does that mean the surface of the area also rises faster? Not necessarily.
The sea level in the North India Ocean rose at a rate of 1.06-1.75 mm – 1 per year from 1874 to 2004 and 3.3 mm year – 1 between 1993-2015.
It is proportional to the increase in the global average sea level.
However, sea level is relatively considered to increase faster.
What is relatively level-level and why did they increase faster in Asia? The sea level is relatively referring to the sea level with respect to the soil.
For example, the north coast of Bengal Bay – West Bengal and Bangladesh – have seen sea level up 5mm and more than a year (compared to an overall 3.3mm in the North Indian Ocean).
This is because Delta Bengal sinks, adds to the effect of rising sea levels.
Land age occurs in many parts of Asia, especially in Delta, due to natural factors and development.
Section Jakarta, for example, sinks as much as 10 cm a year.
What about the rise in sea level in the future in this region? If the Indian Ocean continues to warm up faster than the global average, sea level can begin to rise faster.
Unlike some oceans, most sea level rises in the Indian Ocean are caused by heating – because water expands in volume when warming – and not so much due to smelting glaciers and ice.
But there is uncertainty around the ice sheets, such as the Greenland ice sheet, which contributes to the global average sea level rise.
The Indian Ocean is warming but what does it mean to us?
