Three effects of global warming are; ice caps melting, bird migration, and gas emissions.
Gas emissions effect atmospheric warming • Fossil fuels are the dominate energy source for many years, even though its usage are limited by greenhouse gas. However, countries still today do not have the sufficient sources to bear the expenses of environmental protection.
Fossil fuels (coal, natural gas, oil), which are the raw materials for energy, play an effective and determining role in energy planning, the development of countries.
When the global and regional geographies are evaluated from the geo-strategic and geo-political point of view, it is clearly seen that among all fossil fuels, coal is distributed more equal in ratio than oil and natural gas reserves and that it is gradually gaining importance for the countries that do not have energy resources or that have limited ones or have resources on the verge of exhaustion.
Atmospheric warming has led to significant effects in Turkey especially after 1993. In 2005, tons of CO2 released into the atmosphere moved around the Northern Hemisphere. Turkey also has come under a process of warming/drought, such as other countries, due to the impact of this high CO2.
In recent years, there has been growing discussion of the need for adaptation to climate change. These arguments take various forms, the most reasonable of which is that climate change is already under way, and even with a strong program of greenhouse gas mitigation, we will be facing further unavoidable changes arising from the long residence time of greenhouse gases in the atmosphere.
First, while climate models consistently suggest that the mean global temperature of the planet will rise, mean global temperature is not what any one person, state, or nation will be adapting to. Human beings will be adapting to changes in the weather at the places where they live and a host of concomitant local effects of climate change that ensue from such changes.
While there is broad consensus on the expected change in average global temperature, there is much less agreement between models regarding these local changes and concomitant effects. In particular, there is widespread divergence in model simulations of the impact of global warming.
Bird Migrations Past studies of bird migration times have shown great variation in migratory responses to climate change. They used 33 years of bird capture data (1970–2002) from Manomet, Massachusetts to examine variation in spring migration times for 32 species of North American passerines. They found that changes in first arrival dates the unit of observation used in most studies of bird migration times often differ dramatically from changes in the mean arrival date of the migration cohort as a whole.
The earliest recorded springtime arrival date for each species occurred 0.20 days later each decade. In contrast, the mean arrival dates for birds of each species occurred 0.78 days earlier each decade. The difference in the two trends was largely explained by declining migration cohort sizes, a factor not examined in many previous studies.
They found that changes in migration cohort or population sizes may account for a substantial amount of the variation in previously documented changes in migration times. After controlling for changes in migration cohort size, they found that climate variables, migration distance, and date of migration explained portions of the variation in migratory changes over time. In particular, short-distance migrants appeared to respond to changes in temperature, while mid-distance migrants responded particularly strongly to changes in the Southern Oscillation Index.
The migration times of long-distance migrants tended not to change over time. Our findings suggest that previously reported changes in migration times may need to be reinterpreted to incorporate changes in migration cohort sizes.
Ice Caps Melting The mean sea level has been projected to rise in the 21st century as a result of global warming. Such projections of sea level change depend on estimated future greenhouse emissions and on differing models, but model-average results from a mid-range scenario suggests a 0.387-m rise by 2100.
Al Gore stated that the entire polar ice cap could be completely ice free within the next five to seven years. The scientist he referenced, Dr. WieslavMaslowski, is a Department of Oceanography professor with the U.S. Naval Post- Graduate School. Maslowski denied making the prediction in an interview with the U.K. Times Online. “I would never try to estimate likelihood at anything as exact as this.” A shamefaced Gore admitted gleaning the “ballpark figure” from a conversation he had with Maslowski several years ago. Yet only days before Gore’s Copenhagen speech, the Danish Meteorological Institute (DMI) published a report of Maslowski’s research. It read, “Should the present trend of sea ice melt continue, some models suggest that the Arctic Ocean could become near ice free in the summer time within one decade.”
Regardless of whether, where, or how much ice is melting, total global sea ice extent in the past 30 years shows practically no trend, with 2008 and 2009 peak sea ice seasons equivalent to the 1979-2000 mean.
Consider for a moment a worst-case scenario. What would happen if all of the Arctic sea ice melted? “Sea level would not rise by so much as a millimeter,” said Lord Christopher Monckton, former U.K. science advisor to Prime Minister Margaret Thatcher. Just as melting ice cubes in a glass of water don’t make it overflow, melting sea ice does not affect sea level.
For some time. Many old landmarks are so changed as to be unrecognizable. Where formerly great masses of ice were found, there are now often accumulations of earth and stones. At many points where glaciers formerly extended far into the sea they have entirely disappeared.
