Question 1

IPCC: Intergovernmental panel on climate change

Question 2

The IPCC has done 5 assessments to date

Question 3

193 nations participate in the IPCC

Question 4

There are over 3000 scientists, engineers and technicians involved inthe assessment

Question 5

The assessments provide governments with vital information withregard to climate change. The assessment also seeks to providecritical information with regard to the steps which can be taken tomitigate climate change that is induced by human activities (IPCC,2013).

Question 6

Policy neutral implies that the experts or the scientists involvedin informing the government about world climate must not tell thegovernment what to do or the steps to take. The governments have theresponsibility of deciding the steps it should take and the policiesto implement (IPCC, 2013). Policy relevant implies that theinformation given by the scientists to the governments regardingclimate change must be practical and viable to be changed intopolicies.

Question 7

Adaptation can be viewed as the capacity by the environment towithstand the dangers of climate change. In other words, the systemenhances its ability to reduce vulnerability to the effects ofclimate change (IPCC, 2013). Mitigation can be viewed or said to bethe steps and measures that are taken by authorities to reduce theemission of greenhouse gasses.

Question 8

The assessment report of 2008 received a Nobel price honoring theIPCC for climate change. It clearly stated that warming of the systemis definite. The AR of 2007 indicated that the world was at adangerous place with regard to climate change (IPCC, 2013). Theassessment report called for actions by various countries, as well asfor the 2013 assessment by the IPCC.

Question 9

The key findings for the working group one were as follows it foundout that if greenhouse gas emission was not to be reduced, theeffects could be dire. It was also found out that human activitieshave contributed immensely to the warming of climate since the 1950s(IPCC, 2013). The group also found out that the warming of the lakesand the atmosphere is occurring at an alarming rate and it isdefinite.

Question 10

The scenarios used in this process are the high emission and the lowemission scenarios of the greenhouse gases (IPCC, 2013). The actualemission has also been viewed as a scenario where it is higher thanthe high emission scenario.

Question 11

The reason why some parts are cooling is because the circulation ofthe oceans and the atmosphere. It is clear from the assessment reportthat global warming is about the mean temperature rise (IPCC, 2013).The fact that some places are cooling does not mean that there is noglobal warming.

Question 12

Ocean warming has been said to contribute immensely to the amount ofenergy that is stored in the climate system (IPCC, 2013). The sealevels have continued to rise over the years and this poses a dangerof global warming.

Question 13

The two primary factors have been the melting of the ice sheets intowater, as well as the shrinking of the glaciers in all parts of theworld (IPCC, 2013).

Question 14

The ocean has been said to absorb 30% of the anthropogenic CO2. Thekey consequence of an increase of CO2 in the ocean is theacidification of the ocean water. This affects the ecosystemnegatively. The CO2 also reduces the warmth in the ocean (IPCC,2013).

Question 15

Carbon dioxide and methane are said to be cooling agents. Watervapor is the main gas which causes warming to the atmosphere despiteits existence being temporary (IPCC, 2013).

Question 16

The increase in the greenhouse gas in the atmosphere is a clearindication that the changes are man-made (IPCC, 2013). The positiveradioactive forcing and the systematic climate change, as well as theobserved warming indicates that primary role that humans play inclimate change.

Question 17

The recent warming hiatus has been attributed to coolingcontribution from the internal variability, as well as the reducedexternal forcing from volcanic eruptions.

Question 18

The global temperature is expected to increase by more than 1.5Ocif the emission of the greenhouse gasses continue in the same trend(IPCC, 2013).

Question 19

The global water cycle will no longer be uniform. The report statesthat there will be a bigger difference in precipitation between thedry and the wet regions of the world. However, it also argued thatthere might be exceptions.

Question 20

There will be a huge reduction of ice sheets which will melt andincrease the sea level. The coastal land will eventually be coveredby water as a result of increased sea levels.
