Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the effects of climate change in Australia. [8] Rainfall in southwestern Australia has decreased by 10–20% since the 1970s, while southeastern Australia has also experienced a moderate decline since the 1990s. [5]
Climate change will accelerate the prevalence of pests and diseases and increase the occurrence of highly impactful events. [195] The impacts of climate change on agricultural production in Africa will have serious implications for food security and livelihoods. Between 2014 and 2018, Africa had the highest levels of food insecurity in the ...
As of 2021, $2.3 billion worth of commodities were produced in Australia by the organic agriculture sector, representing approximately 3% of agricultural output. [63] Australia leads the world with 35 million hectares certified organic, which is 8.8% of Australia's agricultural land [62] and Australia now accounts for more than half (51%) of ...
Climate change also has diverse implications for Australia's economy, agriculture and public health. [9] Projected impacts include more severe floods, droughts, and cyclones. [10] Furthermore, Australia's population is highly concentrated in coastal areas at risk from rising sea levels, and existing pressures on water supply will be exacerbated.
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [48] as well as in the 2024 UNEP Actions on Air Quality report. [49]
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Estimated median income loss or gain per person by 2050 due to climate change, compared to a scenario with no climate impacts (red colour indicates a loss, blue colour a gain). [1] An economic analysis of climate change uses economic tools and models to calculate the magnitude and distribution of damages caused by climate change.
Climate change has been a critical issue in Australia since the beginning of the 21st century. Australia is becoming hotter and more prone to extreme heat, bushfires, droughts, floods, and longer fire seasons because of climate change. Climate issues include wildfires, heatwaves, cyclones, rising sea levels, and erosion. [16] [17] [18] [19]
