IPCC Status Report on Climate Change Summary

Abstract
The following is a summary of the IPCC Status Report on Climate Change. The following questions will be answered: is climate change occurring? About which aspects of climate change are we certain? Uncertain? What are the main factors determining climate change today? What is the likelihood that humans have caused these changes and what data supports this conclusion? And finally, what information is not yet available or are we unable to access at this time that may have bearing on the report and our understanding of climate change?

The IPCC Status Report on Climate Change Summary for Policymakers is an assessment of the current scientific understanding of the impacts of climate

The main factors in this climate change are observed to be the increase in temperatures and the resulting acidification of the oceans. The previously mentioned changes and others in the report are readily observable, such as the uptake of anthropogenic carbon since 1750 that has led to the ocean becoming more acidic, with an average decrease in pH of 0.1 units and in some instances blatantly obvious, even to the average layperson. It is difficult to conclude what the rate of change in the future will be and the effects of observed ocean acidification on the marine biosphere.
The report concludes, again with “high confidence”, that anthropogenic (human caused) warming has had a discernible influence on many of our planets physical and biological systems. While there are limitations and gaps in the knowledge available, particularly from undeveloped countries, the knowledge available allowed the group to attribute most of the observed increase in the globally averaged temperature since the mid-20th century to the observed increase in anthropogenic greenhouse gas concentrations. The analysis was necessarily limited in the number of systems and locations considered. In addition, natural temperature variability is larger at the regional than at the global scale, thus affecting identification of changes due to external forcing and at the regional scale other factors such as land-use change and pollution, are an environmental
