Jakarta (ANTARA) – Immediate and large-scale reduction in greenhouse gas emissions is needed to prevent global temperatures from rising to 1.5 degrees Celsius, said Siswanto, a researcher with the meteorology, climatology and geophysics (BMKG).
During a virtual discussion on the climate crisis, accessible by Monday, Siswanto drew attention to the latest report of the UN Intergovernmental Panel on Climate Change (IPCC) which estimated faster global warming.
The report, written by 234 scientists, says greenhouse gas emissions from human activities are responsible for the 1.1 degree Celsius warming observed from 1850 to 1900, he said.

The report estimates that within 20 years on average, global temperatures will exceed or exceed the threshold of 1.5 degrees Celsius, he added.
The report also estimates that each region of the planet will experience a different impact, depending on the level of heat in the region, Siswanto said.
He added that the topography, physiography and morphology of the regions will also be factors that will differentiate the impact of global warming in the regions.
An intensification of the hydrological cycle will also occur, he said.

In this regard, Indonesia will potentially experience extreme rainfall that would cause flooding as well as more intense drought during the dry season, he added.
“This will be due to the intensification of the hydrological cycle,” he said.

The surface level of the oceans will also rise, leading to more frequent flooding in coastal areas and coastal erosion, he added.
Currently, Indonesia’s surface temperature is below the global average, Siswanto said.
However, if the temperature is viewed city by city, then several cities, such as Jakarta, have a higher surface temperature than the global average, he added.
