The climate in Yogyakarta city has gradually increased over the past two years due to global warming, a government agency says.
Previously, the temperature in the city ranged between 33 and 34 degrees Celsius, but now swings between 35 and 37.8 degrees.
"The temperature rise in Yogyakarta is a current global phenomenon also happening elsewhere as the result of global warming," said Yogyakarta Meteorological and Geophysics Agency (BMG) Data and Information Division head Tyar Prasetya.
Prasetya added his office had detected a gradual rise in temperatures in the city over the past two years. The city recorded temperatures of between 33 to 34 degrees Celsius previously, but in November 2006 the highest temperature reached 37.8 degrees Celsius and in December of the same year it stood at 35.2 degrees Celsius.
He said the BMG recorded temperatures of 35.2 degrees Celsius in February and 35 degrees in October this year.
Prasetya said every party must pay special attention to reduce global warming so as to alleviate its negative impacts.
A number of Yogyakarta residents say they have noticed the change.
"Yogyakarta's climate is very hot now, especially when we go out in the daytime," said Amirudin, a father of two.
He said that the atmosphere around the Gadjah Mada University's roundabout, a popular meeting place, used to be cool in the afternoon.
"The climate along Jalan Kaliurang, which was cool previously due to its proximity to the mountain, is quite hot now, let alone the area around the university, which is closer to the coastal area," said Amirudin.
Yogyakarta Environmental Office's Waste Management Division head Peter Lawuasal said his office was conducting a study to determine the current trend in temperature rises.
The study is being conducted in 10 points in the city focusing on tests such as lead levels and ambient temperature.
"We are currently testing them in the laboratory," said Peter.
Peter added his office had previously conducted research on lead content in the blood levels of taxi drivers, bus conductors and pedicab drivers.
"Tests showed that the lead content exceeded the permitted level," said Peter.
He said the lead content in their blood indicates a high level of air pollution in the city.
The local municipality is carrying out a regreening program in an attempt to lower air pollution in the city. It has been using money from the provincial budget to procure idle land in the city for the past two years.
"We buy vacant plots of land and turn them into green areas or public parks," said Yogyakarta Mayor Herry Zudianto.
The tree replanting program is being carried out in conjunction with a campaign to plant trees along streets and in private gardens. The municipality will provide 31,000 tree seedlings by the end of the year and encourage residents to get involved in the program.
