After several false starts for 2021 due to the COVID-19 pandemic, the Sydney Film Festival has managed to return to live screenings at multiple venues with strict COVID safe planning. This is good news for both cinema enthusiasts and the wider film industry which has had to operate under severe disruptions as the pandemic has moved across the world. The impact and efficacy of vaccines has been the game changer for all large gatherings of people particularly for indoor settings.

Sydney Film Festival 2021 - screening in a COVID world
After several false starts for 2021 due to the COVID-19 pandemic, the Sydney Film Festival has managed to return to live screenings at multiple venues with strict COVID safe planning. This is good news for both cinema enthusiasts and the wider film industry which has had to operate under severe disruptions as the pandemic has moved across the world. The impact and efficacy of vaccines has been the game changer for all large gatherings of people particularly for indoor settings.

IPCC 6th Assessment Report - the magnitude of the crisis defined
- Human induced climate change is already affecting many weather and climate extremes in every region across the globe. Evidence of observed changes in extremes such as heatwaves, heavy precipitation, droughts, and tropical cyclones has strengthened since the 5th Assessment Report.
- Global surface temperatures will continue to increase until at least mid-century under all emission scenarios considered. Global warming of 1.5C and 2C will be exceeded during the 21st century unless deep reduction in carbon dioxide (CO2) and other greenhouse gas emissions occur in the coming decades.
- Under scenarios with increasing CO2 emissions, the ocean and land carbon sinks are projected to be less effective at slowing the accumulation of CO2 in the atmosphere.
- Continued global warming is projected to further intensify the global water cycle including its variability, global monsoon precipitation and the severity of wet and dry events.
- With further global warming, every region is projected to increasingly experience concurrent and multiple changes in climatic impact-drivers.
- Low-likelihood outcomes such as ice sheet collapse, abrupt ocean circulation changes, some compound extreme events and warming substantially larger than the assessed 'very likely' range cannot be ruled out.
- Strong rapid and sustained reduction in CH4 (methane) would also limit the warming effect resulting from declining aerosol pollution and would improve air quality.

COP26 Glasgow - reigning in climate change - can it be done ?
COP26 commences on 31 October 2021 in Glasgow, Scotland and concludes on Friday 12 November. But will it achieve the necessary agreement from all the members of the Conference of the Parties (COP) to reduce carbon emissions? This is the 26th meeting and while some progress has been achieved over the years, the target date of zero emissions by 2050 will be too little, too late. Significant reduction is needed much earlier than 29 years into the future and more likely by as early as 2030.

Climate change - Australian business continues action where the Australian Government fears to tread

"The links between climate change and business are becoming
increasingly evident and inextricable. Business decisions and actions will slow
or accelerate climate change, and climate change will drive risks and
opportunities for business. Increasingly, board directors are expected to
ensure that climate-related risks and opportunities are appropriately
addressed. However, limited practical guidance is available to help board
directors understand their role in addressing these risks and opportunities... good governance should intrinsically include effective climate
governance'

Chocolate - food of the Gods - the basic facts
- chocolate is derived from the cocoa bean grown on the cocoa tree.
- the cocoa tree requires intense heat and moisture found in climates located around 20 degrees North and South of the Equator. Too much direct sunlight and wind however is detrimental hence a level of shade is also needed for the tree to thrive. This is usually achieved through the use of an umbrella tree or mother tree that is used to provide such cover (Note climate change with increased temperatures may well effect this essential human food luxury).
- there are two basic beans that are cultivated and from which various hybrids are derived: Criollos and Forasteros.
- Criollos are recognised for their concentrated flavour, are thinner skinned and grow predominantly in Java,Samoa, Venezuela, Sri Lanka and Madagascar.
- Forasteros are often used as a base bean mix, have less flavour, grow in thick walled pods and are mainly found in West Africa and Brazil.
- Cocoa trees produce a waxy pinkish-white blossom which in turn produces pods. During harvesting the pods are cracked open to extract twenty to thirty seeds in a bed of white pulp.
- A period of fermentation around slightly more than a week, is used to remove the bitter acid taste and the white pulp, followed by drying either through the natural sun or through large scale hot air blowers.
- the beans are then transported for commencement of the manufacturing process -in short order: careful roasting of beans, thence the nibbing machine (breaking the husk off to reveal the 'nib' or raw chocolate), grinding the nib to produce cocoa butter and the a brown powder which is pure cocoa. It is the pure cocoa powder which is the base of chocolate.
- the cocoa butter is then reintroduced in varying levels depending on the product being developed. Cocoa butter is only used in small amounts for baking chocolate and larger amounts for chocolate for direct human consumption.

A rise of 3 Degrees Celsius - the impact on Australia
In March this year, the Australian Academy of Science issued a stark warning on the future of this country if global warming is not actively slowed and ultimately stopped. The Academy's report charts both proven existing impacts and the effects of modelled temperature increases. The situation could not be more starkly or clearly demonstrated by the findings of the Academy which included -
Temperature rising
- the total emission reduction current pledged by the Australian and international government through the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement, even if implemented on time will translate as an average global surface temperatures of 3 degrees Celsius (C) or more.
- the planet is well on its way to devastating climate change with average surface temperatures being at 1.1 degrees C above the pre-industrial period. Australia has had a worse outcome with warming on average by 1.4 degrees C.
- limiting climate change to 1.5 degrees Celsius in now virtually impossible.
Ecosystems
- land-based environments have been affected by drought, fire, extreme heatwaves, invasive species and disease, large scale mortality of trees, birds and tree-dwelling mammals
- rising sea levels are amplifying storm impacts damaging coastal ecosystems such as coral reefs and mangrove forests.
Australian agriculture, forestry, fisheries and food security
- reduced water availability and heat stress have contributed to reductions in profitability for broadacre crops such as wheat and barley in the magnitude of up to 22% since 2000.
- heat stress is a significant issue for livestock systems due to impacts on animal welfare, reproduction and production. Projected temperature and humidity changes suggest an increased number of heat stress days per year.
- forestry is facing growing pressure from a warming and drying climate with increased fire risks, changes in rainfall patterns and species-specific pest impacts.
Australian cities and towns
- with close to 90% of Australians living in cities and towns, climate change experience will be manifested in various ways.
- extreme heat wave conditions, bushfires and storms already place pressure on power stations and infrastructure while simultaneously increasing demand for energy supply for air conditioning.
- global sea level rises are already occuring and pose a severe risk to properties infrastructure and ecosystems with coastal flooding becoming a more regular feature. 160,000 to 250,000 coastal properties will be at risk with a rise of 1 metre in sea levels.
- climate sensitive infectious diseases such as Ross River fever and other vector borne diseases shift their geographical distribution and intensity of transmission. This will only increase as climate change increases to above 2 degrees C.
