An analysis of the problems of global warming an increase in the average temperature on earth
Solomon et al. Patterns of rainfall and snowdroughts and stormsand lake and sea ice are changing. Therefore, a key approach is to use physically or statistically based computer modelling of the climate system to determine unique fingerprints for all potential causes.
Average global temperature by year table
These data show that temperatures have climbed to more than 1. This is around double the average annual rise of 0. Industries sensitive to climate change include agriculture , fisheries , forestry , energy , construction , insurance , financial services , tourism , and recreation. The Kyoto Protocol legally binds developed country Parties to emission reduction targets. The year event in Scotland during has become an 8-, and year event in the Eastern, Southern and Northern Scotland pooling regions respectively during the s. For instance, by , global sea level rise would be 10 cm lower with global warming of 1. About 28 percent of the total new development in the seven states over the past 15 years has been in areas within the flood events. This was by far the largest number of countries ever to sign an international agreement on a single day. Additionally, the magnitude of climate change impacts was projected to be smaller compared to the impact of social and economic development.
Human activities have contributed to a number of the observed changes in climate Hegerl GC, et. Despite ups and downs from year to year, global average surface temperature is rising.
The second commitment period began on 1 January and will end in The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun's heat and causing the planet to warm.
The IPCC d and d has organized many of these risks into five "reasons for concern: Threats to endangered species and unique systems, Damages from extreme climate events, Effects that fall most heavily on developing countries and The poor within countries, global aggregate impacts i.
Longer, hotter summers could also lead to the spread of tick-borne illnesses.
Causes of global warming
Solid and liquid particles known as aerosols — from volcanoes, plankton, and human-made pollutants — reflect incoming sunlight, cooling the climate. With medium confidence see footnote 1 , IPCC  concluded that human influences had contributed to an increase in heavy precipitation events at the global scale. The IPCC d and d has organized many of these risks into five "reasons for concern: Threats to endangered species and unique systems, Damages from extreme climate events, Effects that fall most heavily on developing countries and The poor within countries, global aggregate impacts i. Industries sensitive to climate change include agriculture , fisheries , forestry , energy , construction , insurance , financial services , tourism , and recreation. The enhanced greenhouse effect What has scientists concerned now is that over the past years, humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly by burning fossil fuels, but also from cutting down carbon-absorbing forests. In Paris, present-day heat waves persist from 8. Projections of future changes in precipitation show overall increases in the global average, but with substantial shifts in where and how precipitation falls.
The processes that cause such changes are called "forcing mechanisms". Increasing flood risk is now recognised as the most important sectoral threat from climate change in most parts of the world, with recent repeated severe flooding in the UK and Europe causing major loss of property and life, and causing the insurance industry to threaten the withdrawal of flood insurance cover from millions of UK households.
Models project a general tendency for more intense but fewer storms outside the tropics.
