FOR THIS NEWLY READING IN THE NEWSPAPER / INTERNET, SEE TV, GLOBAL WARMING ALWAYS ABOUT NEGATIVE IMPACT. Wrong. Positive impacts also exist.
The IPCC (The Intergovernmental Panel on Climate Change) was established by the World Meteorological Organization (WMO) and The United Nations Environment Program (UNEP) is a panel of scientists from around the world whose main task is to analyze the scientific evidence of global warming and climate change.
The IPCC was formed to address a very complicated issue on climate change. Policy makers need an objective and accurate source of information on the causes of climate change, their environmental, socioeconomic impacts, and alternative mitigation and adaptation to climate change.
According to them, the positive impacts are:
Higher potentials in agricultural yields in areas located in middle latitudes.
The potential for adding global timber to well-managed and well-managed forests.
Increased water availability for the population in some relatively dry areas, for example in parts of Southeast Asia.
Reduction of winter death rates on earth in the middle and high latitudes.
Reduced energy demand for space heating due to the air temperature in winter is not too cold.
IPCC simulates climate change using computer programming called the global numerical climate model (global numerical model) or global circulation models (GCMs). This numerical model is used to simulate global average climate change and compare it with actual regional measurements.
According to the IPCC itself, they acknowledge that there is still uncertainty inherent in the simulation results, since the modeling results are only projections and not predictions, and there are still weaknesses in the simulation and modeling that have no inability to include sunlight and dust radiation volcano in the mathematical equations in the model.
It is important to note that the IPCC only makes scenarios of possible future factors based on trends that have occurred in the past and that are happening at the moment. And again, the scenario is only a projection and not a prediction. Therefore, these projections and scenarios may change depending on whether or not changes occur such as the development of knowledge, changes in human socioeconomic behavior, economic conditions, and so on.
