This article reviews the first to sixth report of Inter-Governmental Panel on Climate Change (IPCC). The types greenhouse gases, sources gases and impact climate change man, animals environment has been identified. strategies combat studied in these reports. A review reports are necessary it is an obligatory document required adverse effects global warming.

Climate change is one of the most serious problems facing the world today. The recent Intergovernmental Panel on Climate Change reports confirmed that climate change will have a significant impact on global surface temperature. The projections of IPCC are that the rise of the mean temperature will be as high as 6.4oC by 2100, while the concentration of CO2 will be 1.3 times higher than it was 2...

We present recent observed climate trends for carbon dioxide concentration, global mean air temperature, and global sea level, and we compare these trends to previous model projections as summarized in the 2001 assessment report of the Intergovernmental Panel on Climate Change (IPCC). The IPCC scenarios and projections start in the year 1990, which is also the base year of the Kyoto protocol, i...

The late David Brower [1], a noted environmentalist, stated “We don’t inherit the environment from our ancestors, we borrow it from our children”. This is a very sobering comment. If the definition of sustainability is that we leave this planet to our children in a better state than we found it, then according to the Intergovernmental Panel on Climate Change (IPCC) [2] we are failing dismally. ...

Forecasts of decadal climate change at subcontinental scales made by global climate models (GCMs) are currently too uncertain to be useful to policy makers. For example, the forecasts of global mean surface temperatures in the current Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions (SRES) A1B scenario show an agreement across 15 models of about ±0.75 K in warming of...

POLICY ACTION ON CLIMATE CHANGE IS INFORMED BY CLIMATE MODEL projections as described most recently in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The models used are general circulation models (GCMs), which numerically represent the physical climate system in three dimensions, including the hydrological cycle. These are complemented by recently de...

Recently, machine learning has been applied to the problem of predicting future climates, informed by the multi-model ensemble of physics-based climate models that inform the Intergovernmental Panel on Climate Change (IPCC). Past work (Monteleoni et al., 2011, McQuade and Monteleoni, 2012) demonstrated the promise of online learning algorithms applied to this problem. Here we propose a novel ap...

Many scientists felt that respect was overdue: as early as 1995, the Intergovernmental Panel on Climate Change (IPCC) had concluded that there was strong scientific evidence that human activities were affecting global climate. By 2001, IPCC’s Third Assessment Report stated unequivocally that human activities are having detectable effects on the earth’s atmosphere and hydrosphere. Prominent scie...
