What possible effects do increasing Earth temperatures have on climate change?

Hotter summers, melting icebergs, flooding, hurricanes, etc.

Some global warming models predict that, though summer might be a little hotter, the largest temperature increases will be seen in the winter. Icebergs melt all the time, and always have. It's a result of exposure to above-freezing water and has nothing to do with climate change or global warming. Flooding will occur because there will be more rainfall, which is a good thing. Hurricanes are caused by the temperature difference between the tropics and the temperate zone. The greater this difference, the more hurricanes will form, and the more powerful they will be. Since the temperatures will increase more in the temperate zone than in the tropics, this difference in temperatures will be reduced. Therefore, there will be fewer hurricanes. What will most likely happen as a result of climate change is the same thing that happened the last three times. Higher birth rates for humans. Lower death rates for humans. Less sickness and disease. Higher crop yields. Less hunger. More abundant animal and plant life. Overall, unusual prosperity for humankind. This is exactly what occurred during the Medieval Warm Period 1,100 years ago. This is exactly what occurred during the Roman Warm period 2,200 years ago. We have historical accounts from those periods that confirm the prosperity of humans under "global warming". We have few surviving historical records from the Minoan Warm Period 3,300 years ago, but archaeological evidence supports the notion that this period was also quite prosperous for humankind. Note the 1,100-year cycle between the previous warm periods, and the fact that the current warm period falls right in line with that cycle, making it likely that the current warming is merely part of the cycle and not caused by anything mankind has done. (There were no SUVs or coal-burning electrical plants back then.) Note also that temperatures during the previous three warm periods exceeded the highest temperatures recorded during the current warm period, and yet humankind prospered. We have nothing to fear from global warming, except that it is very likely to reverse itself long before the alarmists think. In fact, there is evidence that we have already reached the peak temperature of the current warm period, in 1998.

The Arctic Climate Impact Assessment, an international project of the Arctic Council (a high-level intergovernmental forum) and the International Arctic Science Committee (IASC), created for evaluating and synthesizing knowledge on climate variability, climate change, and increased ultraviolet radiation and their consequences, have arrived at the conclusion that the concentration of greenhouse gases and the rising temperatures will cause the accelerated melting of the ice caps, the rising of sea levels, increased storms, decreased water in lakes and rivers, radical changes in weather behavior, reduced animal health, increase in insect populations, and drying of wetlands and other inland areas with simultaneous floods and increased rain in coastal regions.

Even with most countries taking measures to diminish the impact of climate changes, there is not a consensus about the "why", "how" or the consequences of these changes. This is a controversial subject and there is available information from diverse points of view as well as neutral information available in books, sites and studies that may allow to each one to have the chance to freely evaluate the issue by oneself
