Monsoon in April- What's the reason behind sudden climate change?
Winter in April
India is the 3rd largest carbon emission country in world this sort of development making the country populated. The global warming is causing the area more heat and due to that water is getting drained before the time and that's make the monsoon late if we see the climate change in last few years.
It was decreasing till the 2016 as per survey but due to consumption. the world consumes ever more fossil fuel, greenhouse gas concentrations will continue to rise, and Earth’s average surface temperature will rise with them. Based on plausible emission scenarios, average surface temperatures could rise between 2°C and 6°C by the end of the 21st century. Some of this warming will occur even if future greenhouse gas emissions are reduced, because the Earth system has not yet fully adjusted to environmental changes we have already made.
As Nasa observation laboratory report the sun will radiate more solar energy which will me make earth warmer and in danger and the drop of temperature will low and the water will melt down in northen hemisphere making snow melt down which can cause earth in huge danger in upcoming yearsEarth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet.
As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane.
When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.
This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.
The enhanced greenhouse effect
What has scientists concerned now is that over the past 250 years, humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly by burning fossil fuels, but also from cutting down carbon-absorbing forests. Since the Industrial Revolution began in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methane levels have increased 148 percent.
India usually escapes the monsoon rains after mid-September but in 2022 it stretched long until 13 October when the monsoon withdrawal started from northern India and dry weather conditions prevailed.
After the withdrawal of the monsoon, anti-cyclonic circulation forms over western parts of the country which causes dry weather and restricts any kind of precipitation to pass through the region and it takes up to months to get back to the low pressure/ Front systems such as Western Disturbance to hit the region after a high-pressure area dilutes.
Currently, the anti-cyclonic circulation is still existing over Gujarat leading to dry weather conditions – hence a delayed withdrawal of the monsoon can lead to an overall delay in the climatological process. This year the southwest monsoon has withdrawn from the entire country on 23 October against the normal of 15 October.
Global warming causing heat waves in India
India is currently facing a prolonged heatwave, with temperatures exceeding 42°C in numerous cities across the country. This comes just weeks after India recorded its hottest March since the country’s meteorological department began its records over 120 years ago. This image, produced using data from the Copernicus Sentinel-3 mission, shows the land surface temperature across most of the nation. According to the India Meteorological Department, maximum air temperatures reached 43-46°C over most parts of Rajasthan, Vidarbha, Madhya Pradesh and East Uttar Pradesh; in many parts over Gujarat, interior Odisha; and in some parts of Madhya Maharashtra on 28 April. Forecasters warned that heatwave conditions are expected to continue until 2 May. Experts at the Indian Institute of Technology’s Water and Climate Lab stated that, in recent years, the number of Indian states hit by heatwaves has increased, as extreme temperatures become more frequent. Owing to the absence of cloud cover on 29 April (10:30 local time), the Sentinel-3 mission was able to obtain an accurate measurement of the land surface temperature of the ground, which exceeded 60°C in several areas. The data shows that surface temperature in Jaipur and Ahmedabad reached 47°C, while the hottest temperatures recorded are southeast and southwest of Ahmedabad (visible in deep red) with maximum land surface temperatures of around 65°C. The map was generated by using the mission’s Sea and Land Surface Temperature Radiometer instrument. While weather forecasts use predicted air temperatures, this satellite instrument measures the real amount of energy radiating from Earth. Therefore, the map shows the actual temperature of the land’s surface pictured here, which is usually significantly hotter than air temperatures.
