Jakarta (ANTARA) - An immediate and large-scale reduction in greenhouse gas emissions is required to prevent global temperatures from rising up to 1.5 degrees Celsius, Siswanto, a researcher from Meteorology, Climatology and Geophysical Agency (BMKG), has said.


During a virtual discussion concerning the climate crisis, accessed from here on Monday, Siswanto drew attention to the latest report from the UN's Intergovernmental Panel on Climate Change (IPCC) that has estimated faster global warming.


The report, written by 234 scientists, indicates that greenhouse emissions from human activities are responsible for the warming of 1.1 degrees Celsius observed from 1850 to 1900, he said.

The report estimates that within 20 years on average, global temperatures will breach or exceed the threshold of 1.5 degrees Celsius, he added.


The report also estimates that every region on the planet will experience a different impact, depending on the level of heat in the region, Siswanto highlighted.


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 hydrology cycle will also occur, he asserted.

In relation to this, Indonesia will potentially experience extreme rainfall that would cause flooding and also a more intense drought during the dry season, he added.


"This will be due to the intensification of the hydrology cycle," he said.

The ocean surface level will also rise, which would lead to more frequent flooding in the coastal areas and coastal erosion, he added.


Currently, Indonesia's surface temperature is lower than 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.
