Impact of Global Warming for Human Life

The result of the causes of Human Life
Changes in the Climate System

The atmosphere is a system that is Dynamic, so the observation that data quality and maintenance of Network observation density is very important. Processes that lead to climate change can be analyzed with different time scales, and radiation or net available energy dipermukaan earth is very involved in the process. Basically, the condition of energy dipermukaan divided over 2, the input radiation and the sun and how the components editor components to save the earth, distribute and release the energy.

External causes of climate change Input direct sun radiation; Radiasi play an important role in climate change. Through observation satellite is known that the constant sun at this time to become more varied from the previous. One factor is the cause of black spot sun (Sunspot). The more the number of sunspot radiation output of the sun also rises.

Human activity causes climate change.

Characteristics of climate trends in the Intergovernmental Panel on Climate Change (IPCC):

* Global temperature increased 0.6 ° C since the late 19th century
* Heating concentrated in two periods, the years 1910-1945 and 1976-now
* The range of heating 0.2 ° C per decade
* Year of 1900s is a decade terhangat in the last millennium, and 1998 is the year's most warm during this period.
* In connection with changes in temperature, many of glacier melt
* Presipitasi in the mainland increased approximately 2% compared to the last century
* North Europe and North America has been the North mengalamai largest increase presipitasi
* On daeerah Tropical and subtropical trends in climate change is quite small. Although there is a drought in Africa and India in the Rainy Monsunal that last a long time, but not linier pattern found in most tropical regions have increased amount of rainfall.

Global Warming threatens Earth

Global warming is the increase in the average temperature of the Earth's near-surface air and the oceans since the mid-twentieth century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes that anthropogenic greenhouse gases are responsible for most of the observed temperature increase since the middle of the twentieth century, and natural phenomena such as solar variation and volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward. These basic conclusions have been endorsed by 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.

Climate model projections summarized in the latest IPCC report indicate that global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. The uncertainty in this estimate arises from the use of models with differing climate sensitivity, and the use of differing estimates of future greenhouse gas emissions. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Although most studies focus on the period up to 2100, warming is expected to continue after 2100, even in the absence of new emissions, because of the large heat capacity of the oceans and the lifespan of CO2 in the atmosphere.

Increasing global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, likely including an expanse of the subtropical desert regions. Other likely effects include Arctic shrinkage and resulting Arctic methane release, shrinkage of the Amazon rainforest, increases in the intensity of extreme weather events, changes in agricultural yields, modifications of trade routes, glacier retreat, species extinctions and changes in the ranges of disease vectors.

Political and public debate continues regarding the appropriate response to global warming. The available options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming; and, more speculatively, geoengineering to reverse global warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.
