Famine is a likely result if global warming not stopped

Our food system isn’t ready for the climate crisis: The world’s farms produce only a handful of varieties of bananas, avocados, coffee and other foods – leaving them more vulnerable to the climate breakdown

The climate breakdown is already threatening many of our favorite foods. In Asia, rice fields are being flooded with saltwater; cyclones have wiped out vanilla crops in Madagascar; in Central America higher temperatures ripen coffee too quickly; drought in sub–Saharan Africa is withering chickpea crops; and rising ocean acidity is killing oysters and scallops in American waters.
All our food systems – agriculture, forestry, fisheries and aquaculture – are buckling under the stress of rising temperatures, wildfires, droughts, and floods.
Even in the best-case scenario, global heating is expected to make the earth less suitable for the crops that provide most of our calories. If no action is taken to curtail the climate crisis, crop losses will be devastating.

As bad as it is, IPCC Report likely understates reality

Climate News Links on April 10, 2022

Saudi Arabia, India, China, (Australia) and a few other countries have sought to make changes that would weaken the final warnings.

Dire warning on climate change ‘is being ignored’ amid war and economic turmoil: The third segment of the Intergovernmental Panel on Climate Change report is being overshadowed, just like the previous one

…
Saudi Arabia, India, China and a few other countries have sought to make changes that would weaken the final warnings, the Observer understands. Some governments are anxious to avoid policy advice such as cutting subsidies to fossil fuels, even though these are widely espoused by leading authorities.This process of refinement – which has also been a complaint in the previous chapters of the IPCC assessment – is defended by some, as producing a document that all governments must “own”, as they have all had input. But many scientists are growing increasingly f
rustrated, as it produces a conservative and sometimes watered down document that many feel does not reflect the urgency and shocking nature of the threat.

IPCC: Summary of importance of 3 part AR6 Report

Climate News Links on April 10, 2022

Following up on my comprehensive post, The Guardian succinctly explains why the 3 parts of the complete AR6 need to be considered by everyone.

Why are the three IPCC working group reports significant? Explainer: The IPCC has now published all parts of its landmark review of climate science.

The Intergovernmental Panel on Climate Change (IPCC), made up of the world’s leading climate scientists, has now published all three sections of its landmark comprehensive review of climate science.
…
Yet the picture could already be even worse than the IPCC has presented. The IPCC data took in research papers published from 2014 up to last year, but since then the world has experienced even more extreme weather. The IPCC reports are regarded as cautious and conservative by many scientists, and the summary for policymakers that sets out the key messages of each working group are subject to inputs from governments that some regard as watering down.

We ignore those who know most about land we occupy

Climate News Links on March 31, 2022

The world’s first nations people have been surviving since the ice ages on lands we occupy. We ignore their knowledge at our perils.

Indigenous peoples across the globe are uniquely equipped to deal with the climate crisis – so why are we being left out of these conversations?

The urgency of tackling climate change is even greater for Aboriginal and Torres Strait Islander people, and other First Nation peoples across the globe. First Nations people will be disproportionately affected and are already experiencing existential threats from climate change.
The unfolding disaster in the Northern Rivers regions of New South Wales is no exception, with Aboriginal communities completely inundated or cut off from essential supplies.
Aboriginal and Torres Strait Islander peoples have protected Country for millennia and have survived dramatic climatic shifts. We are intimately connected to Country, and our knowledge and cultural practices hold solutions to the climate crisis….

Last Horseman: warming & near-term mass extinction

Climate News Links on March 29, 2022

A 2016 article lays out where we were then compared to past extinctions. We are now closer to point of no return. Warming must be stopped!

Mass extinctions and climate change: why the speed of rising greenhouse gases matters

[G]reenhouse gases are rising faster than at any time since the demise of dinosaurs, and possibly even earlier. According to research published in Nature Geoscience this week, carbon dioxide (CO₂) is being added to the atmosphere at least ten times faster than during a major warming event about 50 million years ago.
We have emitted almost 600 billion tonnes of carbon since the beginning of the Industrial Revolution, and atmospheric CO₂ concentrations are now increasing at a rate of 3 parts per million (ppm) per year.
With increasing CO₂ levels, temperatures and ocean acidification also rise, and it is an open question how ecosystems are going to cope under such rapid change.

Following today’s Apocalyptic topic back to last year

Considers the grim Apocalyptic Horsemen of too many people and too much consumption in a world approaching runaway global warming

by Corey J. A. Bradshaw, et al., 13/01/2021 in The Conversation

Worried about Earth’s future? Well, the outlook is worse than even scientists can grasp

Anyone with even a passing interest in the global environment knows all is not well. But just how bad is the situation? Our new paper shows the outlook for life on Earth is more dire than is generally understood.
The research published today reviews more than 150 studies to produce a stark summary of the state of the natural world. We outline the likely future trends in biodiversity decline, mass extinction, climate disruption and planetary toxification. We clarify the gravity of the human predicament and provide a timely snapshot of the crises that must be addressed now.
The problems, all tied to human consumption and population growth, will almost certainly worsen over coming decades. The damage will be felt for centuries and threatens the survival of all species, including our own.
