Thousands of scientists have repeated calls for urgent action to tackle the climate emergency, warning that several tipping points are now imminent.
The researchers, part of a group of more than 14,000 scientists who have signed on to an initiative declaring a worldwide climate emergency, said in an article published in the journal BioScience on Wednesday that governments had consistently failed to address “the overexploitation of the Earth”, which they described as the root cause of the crisis.
Since a similar assessment in 2019, they noted an “unprecedented surge” in climate-related disasters, including flooding in South America and Southeast Asia, record-shattering heatwaves and wildfires in Australia and the US, and devastating cyclones in Africa and South Asia.
For the study, scientists relied on “vital signs” to measure the health of the planet, including deforestation, greenhouse gas emissions, glacier thickness and sea-ice extent and deforestation. Out of 31 signs, they found that 18 hit record highs or lows.
For example, despite a dip in pollution linked to the COVID-19 pandemic, levels of atmospheric CO2 and methane hit all-time highs in 2021.
Greenland and Antarctica recently showed all-time low levels of ice mass and glaciers are melting 31-percent faster than they did just 15 years ago, the authors said.
Ocean heat and global sea levels set new records since 2019, and the annual loss rate of the Brazilian Amazon reached a 12-year high in 2020.
Echoing previous research, the researchers said forest degradation linked to fire, drought and logging was causing parts of the Brazilian Amazon to now act as a source of carbon, rather than absorb the gas from the atmosphere.
Livestock such as cows and sheep are now at record levels, numbering more than four billion and with a mass exceeding that of all humans and wild land mammals combined, they said.
‘Address the root cause’ Tim Lenton, the director of the University of Exeter’s Global Systems Institute and study co-author, said the recent record-breaking heat waves in western United States and Canada showed that the climate had already begun to “behave in shocking, unexpected ways”.
“We need to respond to the evidence that we are hitting climate tipping points with equally urgent action to decarbonise the global economy and start restoring instead of destroying nature,” he said.
The researchers said there was “mounting evidence that we are nearing or have already crossed” a number of climate tipping points.

The researchers said there was “mounting evidence that we are nearing or have already crossed” a number of climate tipping points.
These include melting of the Greenland and West Antarctic ice sheets, which may now be irreversible on a centuries-long time scale, regardless of how or if the human race slashes its emissions.
They said increasing ocean deoxygenation and warming waters were threatening warm-water coral reefs, upon which half a billion people rely for food, income and storm protection.
“Given these alarming developments, we need short, frequent, and easily accessible updates on the climate emergency,” said the study.

“Given these alarming developments, we need short, frequent, and easily accessible updates on the climate emergency,” said the study.
The authors repeated previous calls for transformative change in six areas: eliminating fossil fuels, slashing pollutants, restoring ecosystems, switching to plant-based diets, moving away from indefinite growth models and stabilising the human population.
They also called for climate-change education to be included in school core curriculums globally in order to raise awareness of the issue.
In the immediate term, they proposed a trio of emergency responses to the climate emergency.
These consisted of “a significant carbon price”, a global phase-out and ban of fossil fuels, and the development of strategic climate reserves such as restoring and maintaining carbon sinks and biodiversity hot spots.
“We need to stop treating the climate emergency as a stand-alone issue – global heating is not the sole symptom of our stressed Earth system,” said William Ripple, a distinguished professor of ecology at Oregon State University’s College of Forestry.
“Policies to combat the climate crisis or any other symptoms should address their root cause: human overexploitation of the planet,” Ripple said.
He added: “We need to quickly change how we’re doing things, and new climate policies should be part of COVID-19 recovery plans wherever possible.”
I'm gonna need a bigger grill.
Convocation of fools and liars. Normal people understand that with respect to the climate, “tipping points” is a fake concept. And talking about the weather is no substitute for actual research.
” World tipping ... will it really matter?”
The tip if there is one might be toward a better world. Most people, and also plants, prefer warmer weather.
I teach people to ride motorcycles. As such I am outside on a big parking lot for several hours each day. I have done this for years. This year the sunlight feels hotter than other years. Usually the sun shining on me would seem to be about the same temperature as the surrounding air. This summer however when the sun shines and I am in it the radiant energy feels uncomfortably hot to the point where I have to shield my body and eyes. I have not felt that much radiant energy in the past 15 years.
14,000 scientists! Not so hard to get signatories when they know those that decline to sign will have their careers ruined.
I forget, is the the 8th, 10th, or 11th or so time we’ve hit “the” so-called irreversible “tipping point?” I thought by now we were all supposed to be huddling in misery, either freezing, baking, or swimming. It’s so hard to remember which climate disaster is in favor.
Thousands of scientists warn climate tipping points ‘imminent.
🐂💩
🐄💩
And how many bison were there before they were almost exterminated.
Oh noes the ozone layer is gone!!!!!/s
Ask Dr. Willie Soon about the next thirty years of cold.
What a difference today from the FEAR PORN of fifty years ago!

Coming again!
Follow the money. Most scientists that I have met in my 57 years are nothing more than prostitutes. They will provide skewed and twisted data to support whatever conclusions the government and big business want for right amount of money.
Lack of sunspots. Thus the sun puts out more energy. I believe the sun is at the point in some cycle where this happens.
Assuming same parking lot, time of day and time of year?
It’s possible you’ve changed. I notice the cold more lately. Top of my balding head sweats more. Hot sauce now makes me sweat.
Maybe virus or vaccine affects us?
The scientific paper I would enjoy reading is the correlation/causation of government funded climate scientists and their support for governmental economic regulations.
It’s amazing how these supposedly educated folks can sometimes be so wrong. How did we ever manage to get this far & largely without the help of the “climate change experts”? Who do they think made this planet for us with the things we needed for life so long ago? It wasn’t them & I’d suggest they leave things alone that they shouldn’t monkey with.
Well, okay then. We is all gonna die!
Is there some Peer Studied Scientific proof that something Mankind can do or stop doing (besides existing) will change the Climate of the Planet?
Can Mankind create Glaciers?
Can Mankind stop Volcanic Eruptions?
Can Mankind change Ocean Currents or the Jet Stream?
Apparently Mankind can’t tell what Sex someone is or accurately count Election Ballots, so I just don’t see it.
