Climate Has Changed

Bandung, fitb.itb.ac.id (25/10) The weather extremes, more frequent tropical storms, and shifting seasons is a phenomenon of climate change. The emergence of the phenomenon in Indonesia is recognized is an indication that climate change is already happening in Indonesia.

Chairman of Meteorological Studies Institut Teknologi Bandung (ITB) Armi Susandi, contacted on Sunday (15/2) in Jakarta, asserted, “It’s already the implications of global warming and an indication of climate change.”
Global warming, says Armi, has led to increasingly uneven pattern of temperature and pressure spatial (space). The temperature difference occurs between the area of ​​subtropical and tropical regions, also in the subtropical or tropical regions themselves that resulted in the movement of air. The higher the difference in air pressure due to the temperature difference caused wind grew louder and can give birth at a certain latitude storms. Differences in temperature extremes may trigger weather extremes.

Calculation of the growing season and no longer fishing seasons precision. Disasters have always come good in the dry season and the rainy season.
Climate change is confirmed by the analysis that has been done Meteorology, Climatology and Geophysics (BMKG) of processing the data taken for 50 years. Head of Climatology and Air Quality Analysis BMKG Soetamto, last Friday in Jakarta, said, “It’s to see the trend shown as the impacts of climate change.”

The analysis resulted in five maps tendency 1951-2000 period designated as the impact of climate change in Indonesia. The map includes changes in the length of the season, the beginning of the rainy season, the beginning of the dry season, rainfall in the rainy season, and rainfall in the dry season.
Another indication is the increasing intensity of tropical cyclones that cause high waves. “Tropical cyclones in the Indian Ocean on average every year occur 7-8 times in a span of five months from November to March. Rarely collect as four cyclone Charlotte, Dominic, Ellie, and Freddy in a period of less than one month, “said Arnold Mezak Ratag, lecturer at the Faculty of Earth Sciences and Technology, Institute of Technology Bandung, Saturday.

Four tropical cyclones occurred in a period of 28 days, between January 11 to February 7. Consequently, there is high waves in the waters of Indonesia, ranging from the waters west of Sumatra to the east Nusa Tenggara.
The impact of climate change among other islands are sinking due to rising sea levels due to melting of polar ice, drought, flooding, climate uncertainty, and extreme weather. These events will directly threaten the income and livelihood of fishermen, coastal communities, and farmers because the impact on the declining agricultural productivity. Nationally, these conditions can disrupt food security.
