The world, as we know, is getting warmer and warmer. Weather across the globe is changing significantly, and it’s all down to climate change. From increasing sea levels, the melting of polar ice caps and not forgetting constant reports on hurricanes and heatwaves, the world is going through a climate crisis, and there isn’t long left to attempt to reverse the changes that have been made to our environment.
Evan following the huge European heatwave recently, and mass historical data showing that there’s ‘no doubt left’ regarding global warming, one place, in particular, is expected to be hit harder than any other.
That place is Australia.
Due to Australia being located within the southern hemispheres, the seasons are opposite of North America and Europe and feature an abundance of diversity. This includes everything from golden sandy beaches and tropical rainforests to a rich coral reef, filled with diverse marine life, huge, sparse deserts and equally as vast grazing lands.
As you may know, the majority of the population in Australia is confined to the edges of the country, with most people living within the cities and larger towns.
While Australia is warm, and known to be an extremely hot country, 2018 was the third-warmest since records began, with the mean temperature sitting and 1.14°C above average.
While this may not seem much considering the already warm nature of Australia, it’s quite an alarming statistic. Alongside this, the warmth was persistent throughout the year with many of the months recording temperatures within each month’s top ten.
Rainfall was also down, standing at 11% below the average when compared to 1961 – 1990. You can find the rest of the stats here.
These shocking figures have continued into 2019.
During May, Sydney, Darwin, Melbourne and Brisbane were all facing water restrictions. This was due to dams only being 50% full, or lower, as a result of higher temperatures and low rainfall.
The statistics for Sydney are considerably alarming. As the lowest dam percentage since 1940, the 11 dams were at a combined capacity of 55%, which itself was down by 18% in the year from May 2018.
Measured through high tech devices, similar to ones available from RS Components, Sydney went on to receive its first water restrictions in more than a decade as drought gripped New South Wales.
Meanwhile, high temperatures and low rainfall are expected to continue according to The Bureau of Meteorology.
As you can guess from the warnings issued to the population of the world as a whole, climate change is only going to get worse unless something is done, and this applies greatly to Australia.
Back in 2015, it was reported that by 2090 it was predicted that the temperatures would rise by up to 5.1 degrees Celsius in Australia alone. As you can see, this is already happening, with significant rises just three to four years after the comprehensive report was put together.
Alongside this, sea level rises were also expected to increase significantly too. This was projected to be between 26 – 55 cm under low emission scenarios, whereas high emissions scenarios could see rises between 45 – 86 cm. This was estimated based on relative data between 1986 and 2005. If scenarios were worse, then sea level rises could be between one and three metres after 2100.
With the majority of the population living in built-up areas on the edge of the country, which is where much of its tourism comes from too, things could get worse for Australia in more ways than first imagined. With a climate crisis dangling above us, the time to act on it is now to prevent these scenarios from happening or worse, happening quicker than first thought.
