This assignment requires exploration of the Climate Change in Australia (CCIA) website and1se of several projections tools to find relevant climate projection information.
This assignments assesses your ability to follow instructions, identify the correct data, andanalyse that data in appropriate ways. Marks are awarded for accurate and complete answers
to every part of the questions asked.
Start by looking around the CCIA website –
To do this assignment you need to use several projections tools(https://www.climatechangeinaustralia.gov.au/en/projections-tools/) to cbtain the information
required to answer each question.
Use figures and tables from the projections tools as appropriate in your answers. Based onthese make your own assessment of the level of confidence in the changes shown, and reportthis when you discuss the changes. Every figure and table should have a caption that explainswhat is shown.
Submit your assignment as a pdf file.
Imagine you have been asked to provide climate change information to the agricultureindustry. Answer each question below for this audience.
Q1(50%): The Murray River Basin produces a significant part of Australia’s agriculturalproduce. Summarise (with appropriate figures) the projected climate change for this area. Usethe”Summary Data Explorer”.Differences between seasons are important for agriculture so besure to include this. Be sure to include any variables that may be important to agriculture, aswell as indicating the level of confidence in any reported change. How does emission scenario
and future time frame affect the projected changes?
(Max 500 words not including figures and figure captions.)
Q2(20%): Use the”Extremes Data Explorer” to examine projected changes in extremes for theMurray Basin. How does season, emission scenario and future time frame affect the projectedchanges? How much confidence do you have in these projected changes? Highlight thosehanges which have the highest confidence.
(Max 250 words not including figures and figure captions.)
Q3(15%o): Use the”Thresholds Calculator” to answer this question.
Stone fruit requires a minimum length of time spent at low temperature for the flowers to bud.This is referred to as a chilling requirement. While there are a numbers of ways to measure thiswe will use the number of nights where temperatures fall below 6C. A peach grower nearShepparton Victoria needs at least 70 chilling nights per year for his fruit to grow. UnderRCP8.5, when will this variety of peach no longer fruit? Under RCP4.5, when will this variety ofpeach no longer fruit? How important is the emission scenario to this farmer? Remember toassess your confidence in each of these changes.
(Max 150 words not including figures and figure captions.)
Q4 (15%): Use the “Thresholds Calculator” to answer this question.
Very high temperatures can dramatically reduce wheat growth and grain production. A farmernear Wagga Wagga NSW is growing a winter (May-October) wheat variety that is stronglyimpacted once temperatures exceed 35C. Under RCP8.5, when does this first happen morethan one day per year on average? And when does this happen with very high confidence (eventhe minimum estimate is more than one day per year)? How does this change under RCP4.5?
