Changes in Earth's orbit triggered ancient climate change and megadroughts

An international research team has found a strong link between megadroughts and a subtle but powerful force - changes in Earth’s orbit.

We used a morphological approach to identify #megadroughts globally over the past 40 years and applied plant-greenness indices to determine the impacts on vegetation. Megadroughts are increasing in frequency, area and intensity on the global scale. https://www.science.org/doi/10.1126/science.ado4245

[Short film]: #Megadroughts and #IndigenousVoices

"The Southwestern United States is experiencing a megadrought, but this isn’t the first time people have survived one in the region. By highlighting ideas and practices from #Navajo tradition, this story by Native Outdoors of Colorado Plateau re-centers our relationship to water."

#ClimateChange is a #humanrights issue
Well documented that runaway #carbondioxide, #deforestation, resource depletion and the acidification of the #oceans have contributed to increased #heatwaves and #megadroughts, more frequent and violent storms and unseasonable precipitation.
Simply put climate change poses clear threats to human life by exacerbating “existing medical conditions such as cardiovascular, respiratory and kidney conditions or mental illnesses and stress.”

Climate change is a human rights issue

Climate change poses clear risks to human rights around the world. It is essential that people hold governments and decision-makers to account.

New #climate modelling suggests Australians should be preparing for the possibility of #megadroughts lasting more than 20 years.

Scientists warn Australians to prepare for megadroughts lasting more than 20 years

Australian research shows naturally occurring megadroughts will be more severe and last longer due to climate change.

"#Australia could soon see #megadroughts that last for more than 20 years, according to new modelling from The Australian National University (ANU) and the ARC Centre of Excellence for Climate Extremes."

But wait, there's more:

"The researchers' bleak findings are before factoring in human impact on the climate since the Industrial Revolution."

#Megadroughts in the Common Era and the Anthropocene:

"Exceptional drought events, known as megadroughts, have occurred on every continent outside Antarctica over the past ~2,000 years, causing major ecological and societal disturbances" 👇

Megadroughts in the Common Era and the Anthropocene - Nature Reviews Earth & Environment

Megadroughts can be defined as persistent, multi-year droughts that are exceptional compared with other regional events during the Common Era. This Review discusses palaeo reconstructions of megadroughts over the past 2,000 years, and outlines the impact of anthropogenic forcing on the severity and frequency of observed and projected events.
