HOTTEST NOVEMBER IN AUSTRALIA
November 25, 2020
Australia recorded it's hottest temperature ever, reaching 41.9C (107.4F). Meteorologists attribute these high temperatures directly to climate change. These record-breaking temperatures are a cause for alarm as Australia braces for it's next wildfire season.
“Nobody on this planet is going to be untouched by the impacts of climate change.”
-Rajendra K. Pachauri, IPCC chairman (2002-2015)
Implementing global warming adaptations now will cost ~$1.8 trillion.
The world currently spends ~3x that amount subsidizing fossil fuels.
An investment now would return $7 trillion net gain to the global economy.
If we don't take immediate action, fixing global warming will cost over $20 trillion by 2030.
Climate change has been linked to a number of health impacts including:
Asthma: air pollution and smoke inhalation from wildfires
Cardiovascular failure: air pollution and extreme heat
Malnutrition: flooding and impact to water systems
Mental illness: forced migration and civil conflict due to drought/ severe weather
Viral diseases: changes in vector ecology
... and many more.
Flooding and drought decimate crops and farmland, sometimes for many years. People who depend on local agriculture are faced with famine.
Wildfires, droughts, severe weather storms, and warming oceans all impact the habitats of local wildlife.
As vertebrate, plant, and insect species struggle to adapt to the warming environment, endangered animals are pushed closer to the brink of extinction.
Global warming is accelerated by feedback loops:
Permafrost thaw: releases tons of sequestered carbon and carbon-emitting microbes
Melting ice caps: smaller ice caps reflect fewer sun rays and the dark surrounding ocean absorbs heat
Warming oceans: cold water acts as a carbon "sink", whereas warm water absorbs less carbon
De-forestation: Wildfires and drought kill trees which not only releases carbon but shrinks forests, which normally act as a natural carbon sink.
