He explained that the weather is hotter and hotter at this time because it is in the transitional season for Jakarta and around West Java, which starts from the dry season to the rainy season. READ ALSO – Ready to Eat, Heat Wave Cooks Clams in Pacific Ocean
“This is also before October, usually the sun will be around the Equator and will tend to move south, so that later around October 23, it will be 23 degrees at south latitude, that means it will pass through Java,” he said when contacted via telephone. short message, Tuesday (21/9/2021)
This condition is known as the sun combination point, which is positioned directly above our heads. So you will feel stronger solar radiation dUsually, it usually causes hot weather during the day.
Now, when it comes to temperature changes in Jakarta, which are 1.4 degrees Celsius stronger than global warming, it is actually a measure that expresses changes in surface temperature that have been calculated from pre-industrial times to the present day.
“So it’s been around, if the pre-industrial era existed from the 1850s to the 1900s, it means that the BMKG data until now shows that Jakarta’s temperature has a slope or the rate of change is much higher than the global rate of change,” he explained.
“Well, global warming or global changes reported by the WMO (World Meteorological Organization) has been 1.2 degrees Celsius since pre-industrial. If Jakarta from research alone 1.6 degrees Celsius, for the last 135 years,” he added.
If referring to the Paris Agreement, ask all signatory countries to stop the rate of global warming no more than 2 degrees Celsius.
“If we are ambitiously 1.5 degrees Celsius. We are asked to conduct studies so that the global warming rate is not more than 1.5 degrees,” he said.
Currently, Siswanto continued, the entire earth’s surface is 1.2 degrees Celsius, meaning that it still has 0.3 degrees Celsius time to not reach 1.5 degrees. And about 0.8 degrees Celsius to not reach 2 degrees Celsius.
“But if we calculate per local, actually Jakarta is already over 1.5 degrees in the last 135 years.”
