Bushfires have been blazing in Australia since September, and they’ve intensified this week to “apocalyptic” levels, as more than 15.6 million acres have burned so far.
The fires have killed at least 25 people and destroyed 2,000 homes. Experts also estimate that over 1 billion animals have died since the fires began in September.
If you’re having trouble visualizing the scope of these fires, here’s a comparison using a map of the US. Officials say that the fires may burn for months.

As climate changes, Sydney is at greater risk to bushfire events. In an extreme bushfire events Sydney would not be able to cope due to our management hierarchy system. The solution will be to reconstruct our emergency management system. The new system will be more efficient in response time, true coordinated government hierarchy, accountability for each level of government involved and better allocated and multi skilled resources.
The managing director of Sydney, Australia-based Pegasus Research, Dr. Nick Catsaras, possesses more than three decades of experience in information technology and finance. Outside of his career, Dr. Nick Catsaras’ interests include environmental issues.
An article published on March 12, 2021, in Science journal illustrates the environmental crisis that Australia is facing. In the past decade, three Australian species have become extinct, and since 2020, over 7.7 million hectares of land inhabited by threatened species have been destroyed. In February, the Australian government published a report offering recommendations on the failed effort to halt species extinction.
There is skepticism about whether the recommendations will be implemented. The article notes that the most urgent initiative is for the Federal Government to create legally binding National Environmental Standards, strongly enforced and grounded by Indigenous participation. Australia is home to approximately 600,000 species that face mass extinction if reforms are not carried out.

The document summarizes three natural disasters: the 2018 Kerala floods in India, the 2019-2020 Australian bushfires, and the 2020 Taal Volcano eruption in the Philippines. The Kerala floods were caused by heavy rainfall and resulted in over 480 deaths. The Australian bushfires started in late 2019 and burned over 18 million hectares, killing 34 people directly and over 400 from smoke inhalation. The Taal Volcano erupted in January 2020 in the Philippines, forcing over 200,000 people to evacuate and raising health concerns from volcanic ash.
Wildfires can occur anytime, anywhere, and are frequently brought on by human action or a natural occurrence like lightning. It is unknown how 50% of the wildfires dataset that has been reported got started.

A number of studies indicate that tropical arthropods should be
particularly vulnerable to climate warming. If these predictions are
realized, climate warming may have a more profound impact on
the functioning and diversity of tropical forests than currently
anticipated. Although arthropods comprise over two-thirds of terres-
trial species, information on their abundance and extinction rates
in tropical habitats is severely limited. Here we analyze data on
arthropod and insectivore abundances taken between 1976 and
2012 at two midelevation habitats in Puerto Rico’s Luquillo rainforest.
During this time, mean maximum temperatures have risen by 2.0 °C.
Using the same study area and methods employed by Lister in the
1970s, we discovered that the dry weight biomass of arthropods
captured in sweep samples had declined 4 to 8 times, and 30 to
60 times in sticky traps. Analysis of long-term data on canopy arthro-
pods and walking sticks taken as part of the Luquillo Long-Term
Ecological Research program revealed sustained declines in abun-
dance over two decades, as well as negative regressions of abun-
dance on mean maximum temperatures. We also document parallel
decreases in Luquillo’s insectivorous lizards, frogs, and birds. While El
Niño/Southern Oscillation influences the abundance of forest arthro-
pods, climate warming is the major driver of reductions in arthropod
abundance, indirectly precipitating a bottom-up trophic cascade and
consequent collapse of the forest food web.

From pole to pole, climate warming is disrupting the biosphereat an accelerating pace. Despite generally lower rates of
warming in tropical habitats (1), a growing body of theory and data
suggests that tropical ectotherms may be particularly vulnerable to
climate change (2). As Janzen (3) pointed out, tropical species that
evolved in comparatively aseasonal environments should have nar-
rower thermal niches, reduced acclimation to temperature fluctu-
ations, and exist at or near their thermal optima. Consequently,
even small increments in temperature can precipitate sharp de-
creases in fitness and abundance. These predictions have been
verified in a variety of tropical reptiles, amphibians, and inverte-
brates (4–8).
Given their abundance, diversity, and central roles as herbi-
vores, pollinators, predators, and prey, the response of arthro-
pods to climate change is of particular concern. Deutsch et al. (5)
predicted that, .

Climate change: the livestock connectionAndrew Knight
The human-caused (anthropogenic) rate of species extinction is already 1,000 times more rapid than the ‘natural’ rate of extinction typical of Earth’s long-term history, with the result that we are currently living through one of the very few mass extinctions to date. It is clear that climate change represents the greatest threat to life on Earth for many millennia.
Given the urgency with which we must reduce the size of our collective ecological footprint, it is remarkable that so little attention has been afforded to livestock production. The inconvenient truth is that the emissions resulting from clearing land to graze livestock and grow feed, from the livestock themselves, and from processing and transporting livestock products, are greater than those resulting from any other sector. These factors are explored, as are the profound impacts of climate change on global food security.
Strategies for mitigating the environmental damage created by livestock production are reviewed. It is clear that replacing livestock products with alternatives would be the best strategy for reversing climate change, and would have far more rapid effects on green house gas emissions and their atmospheric concentrations, than actions to replace fossil fuels with renewable energy sources.
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

4. About half a billion animals have been affected by the
fires across NSW, with millions likely dead -- and
that's a conservative estimate. That number of total
animals affected could be as high as one billion
nationwide, according to ecologists from the
University of Sydney.
The figures for NSW include birds, reptiles, and
mammals, except bats. It also excludes insects and
frogs, so the real sum is almost certain to be higher,
the ecologists said.
Almost a third of koalas in NSW may have been killed
in the fires, and a third of their habitat has been
destroyed, said Federal Environment Minister Sussan
Ley.
