due to the growth of industries and factories, deforestation and other environmental degradation a well as greenhouse gases have been increasing greenhouse gases on the earth's surface in recent decades. this increase disturbs the climate of the earth and is called climate change. an increase in greenhouse gases in the future could exacerbate the climate change phenomenon and have several ...

In the ongoing political debate on climate change, global mean temperature change (1Tglob) has become the yardstick by which mitigation costs, impacts from unavoided climate change, and adaptation requirements are discussed. For a scientifically informed discourse along these lines, systematic assessments of climate change impacts as a function of 1Tglob are required. The current availability o...

Climate is a complex system which is changing mainly due to the increase of greenhouse gases. Because of the importance of climate change and the effects it can have on water resources, in recent years, this topic has been taken into consideration for different basins on Earth. The objective of this study is to investigate the effects of climate change and forecasting meteorological variables o...

An impressive number of new climate change scenarios have recently become available to assess the ecological impacts of climate change. Among these impacts, shifts in species range analyzed with species distribution models are the most widely studied. Whereas it is widely recognized that the uncertainty in future climatic conditions must be taken into account in impact studies, many assessments...

climate change impacts on precipitation and temperature world-wide are not yet well understood (especially for precipitation), due to their complexity and regional variability. in this study in order to explicit the impact of climate change on precipitation and temperature in iran, 15 aogcm whose greenhouse gases scenarios ran under a2, a1b and b1 were used. monthly precipitation and temperatur...

as a direct consequence of warmer temperatures, the hydrologic cycle will undergo significant impact with accompanying changes in the rates of precipitation and evaporation. climate change will cause changes in climate variable such as precipitation, temperature, sunshine hours, wind speed and etc. so as a result of climate variable change, the related variable such as potential evapotranspirat...

The Updated Trewartha climate classification (TWCC) at global level shows the changes that are expected as a consequence of temperature increase and imbalance precipitation. This type is more precise than Köppen classification. Predictions included in (T °C) change amount precipitation (PA mm). Two models MIROC6 IPSL-CM6A- LR were used, along with 4261 meteorological stations from which data on...

The Public Policy Institute of California is dedicated to informing and improving public policy in California through independent, objective, nonpartisan research on major economic, social, and political issues. The institute's goal is to raise public awareness and to give elected representatives and other decisionmakers a more informed basis for developing policies and programs. The institute'...

To investigate possible future climate changes in California, a set of climate change model simulations was selected and evaluated. From the IPCC Fourth Assessment, simulations of twenty-first century climates under a B1 (low emissions) and an A2 (a medium-high emissions) emissions scenarios were evaluated, along with occasional comparisons to the A1fi (high emissions) scenario. The climate mod...
