CHANGE INPUT DATA     INPUTS   By changing variables on the Climate Change Calculator the user can see the impact of climate change and how our efforts to halt it, impact on future factors such as:
reduction of emissions, water and food shortages, rate of land degradation, costs and benefits..

INCLUDED COSTS      BUDGET TABLE  Costs for government emission reduction measures are calculated by a percentage of GNP/Capita for each country. Costs for bio-agriculture include; conversion and support, R&D, measurement, farm inputs, information and job creation.

POTENTIAL FOR NATIONS WITH EXTENSIVE AGRICULTURAL LAND        carbon neutralTry setting the Interactive calculator to Australia with inputs of;- 1% Govt. reductions by 2020 and only 4% by 2050, 1.5% per year land conversion and 2t /ha/y of CO2-e sequestration. The results show that even with a continuation of business as usual, Australia can still be carbon neutral by 2049.

  • DATA SOURCES     PART GRAPH   Benefits are calculated on the basis of carbon prices set for that particular year.  Land degradation and land regeneration; food and water shortage and availability are all projected through scientific data taken over the last forty years


     How To Use The Climate Change Calculator

  1. Go to download page and download file for country or region of interest.
  2. Open file and change input data.
  3. As input data is altered, emission reduction summary, budget totals, results summary and graphs change accordingly.






     1. Input Data Table

At the top of the page is a table where input data can be inserted. Figures in the yellow boxes can all be changed. As these figures are changed all the results in the tables and graphs below will alter accordingly. The figures shown here are the default settings - based on the minimum emission reductions for the world to limit temperature increases to 2 degrees C. (IPCC category 1)

    2. Emission Reduction Summary

Below the Input data table is the Emission Reduction Summary table This table is the core results table of the calculator. It shows emission reduction percentages for 2020 and 2050 as well as the projected temperature rises that would result from these reductions. The temperature rise figure is based on published IPCC categories.


As you change inputs to the calculator - such as government emission reductions or amount of land converted to bio-agriculture - then the percentages for 2020 and 2050 will alter accordingly. If any of the three results cells change in colour from green to red, as in the example below, this means IPCC conditions for a 2 degree maximum temperature rise have not been met.

Once the desired emission reduction targets have been achieved, ie all three cells being green, one can explore other graphs and tables in the calculator for more detailed information.


    3. Budget Tables

Below the Emission Reduction Summary table is a budget table. This shows budget figures for Government, bio- agriculture and farmers. Below is an example of the farmer's budget for Australia. This shows for example that with the above input figures (default settings) in 2020 Australian farmers will have a net yearly benefit of $158 per hectare of land that is converted to bio-agriculture.

    4. Special Budget Table

Below the budget tables is a special budget table showing budgets up till 2050 with results at five yearly intervals. The selection below shows that with the above input figures, Australia would have a net loss of $32billion by 2020. By including a conversion to bio-agriculture this loss is transformed to a benefit of $349billion.



     5. Results Tables

Below the budget table are four Results Summary tables. The first two tables compare the figures for the particular country with those of the world. The table below shows various emission reduction figures for Australia and the world. It can be seen that even though Australia has such a high level of emissions per capita, because of its large area of agricultural land it still has the capacity to reduce emissions by 200%.



       6. Graphs

At the bottom section of the page are six graphs. The first three show information relating to different aspects of CO2 emission reductions. The second three graphs show information relating to land degradation and water usage.


The graph shown below illusrates emission reductions as a percentage of 2000 levels for the world as a whole.


      This graph shows that by 2050 there will have been :

  • an 84% increase of emissions with BAU (business as usual)
  • a 15% decrease of emissions with government emission reduction measures.
  • a 76% decrease of emissions by adding a 2.5% per year increase of land farmed with bio-agricultural methods to government emission measures.
