Climate Change and the Need for Future Research

Abstract

Climate Changes have impacted our planet since the beginning of time. These were manifested by cyclic Ice Ages and Warm Periods ever since. The changes were caused by natural forcing such as, continental drift, plate tectonics, major volcanic eruptions, and internal dynamics of earth and oceans interactions with the atmosphere. The present warm period, the “Holocene Epoch”, is not different from other such periods except for the sharp global warming which began at the onset of the industrial revolution. This was proven by scientific research to be due to anthropogenic drives, i.e., increased fossil fuel burning and increased Co2 and other Green House Gases (GHG) emissions into the atmosphere. These gases trap the sun radiation reflected from earth surface and result in higher earth temperature. The steep rate of rise in temperature trend since 1960s is directly linked to the use of much more fossil fuels in power production and transportation. This has led to more research to quantify the changes and their impacts on the environment and humans. This paper gives a brief history of the scientific research carried out hitherto and policy suggestions made so far to combat the negative impacts of the increasing global warming of the world. Needed future scientific research in this field is outlined, while at the same time suggesting the needs of Iraq of such research. This includes among other things, forming a regional scientific panel for the Middle East countries (ME. IPCC) for carrying out research on regional level, fostering research on national level, encouraging academics for climate change-oriented research and providing the necessary funds and facilities for such research.
