The World’s First Climate Tipping Point Has Been Crossed, Scientists Say
The exact moment when Earth will reach its tipping points—moments at which human-induced climate change will trigger irreversible planetary changes—has long been a source of debate for scientists. But they might be closer than we think. A report published today says that the Earth has passed its first climate tipping point.
The second “Global Tipping Points” report published by the University of Exeter found that warm-water coral reefs are passing their tipping point. Rising ocean temperatures, acidification, overfishing, and pollution are combining to cause coral bleaching and mortality, meaning that a large number of coral reefs will be lost unless the global temperature returns towards 1°C warming or below.
“We’re in a new climate reality,” said Tim Lenton, founding director at the Global Systems Institute at the University of Exeter, who led the report. “We’ve crossed a tipping point in the climate system, and we’re now sure we’re going to carry on through 1.5°C of global warming above the prior industrial level, and that’s going to put us in the danger zone for crossing more climate tipping points.” The planet is predicted to cross the 1.5°C threshold within the next 5 years, according to a report from the World Meteorological Organization. Once that threshold is reached, the planet will see more frequent and intense extreme weather and strains on food production and water access—impacts many nations vulnerable to climate change are already seeing.
First off, those last three have nothing to do with global warming, natural, anthropogenic, or a mixture. And, if the cultists and politicians and activists weren’t so caught up their alarmism we could spend time dealing with real problems. Ad for warming ocean temps, well, that has happened many times throughout the Holocene. Further, many corals created islands and atolls when the oceans were much higher.
There are other measures of the environment’s health that scientists are also watching. A September report found that we’ve already passed seven of the nine “planetary boundaries” (including the ocean becoming more acidic and the transformation of natural landscapes)—these are thresholds that keep Earth’s systems hospitable to life and protect against breaching a tipping point.
Always doom with these people. Surprised they haven’t gone complete psycho due to getting no sleep and their anger.

But, but, but, I thought the first climate tipping point had been passed in 2007? or was in 2012? Or January 20, 2017?
It’s just so hard to keep track of these things!
“The planet is predicted to cross the 1.5°C threshold…”
Because we’re still coming out of the coldest period of the last 1,000 years… This prediction could have been made in 1700 if we had the prior historical data we have now.
from the article…
++++Scientists have found as many as 25 major tipping points, including the Amazon rain forest transforming from a lush forest that stores carbon emissions to a dry savannah, and the permanent melting of polar sea ice whereby the dark open water absorbs more heat compared to white snow, encouraging further melting.++++
The Earth continues to warm from the atmospheric CO2 that we’re adding by burning fossil fuels.
And J continues to claim CO2 is the cause of the warming absent any verifiable cause-effect evidence.
On top of that, these so called “climate tipping points” are arbitrary values, not scientifically derived values.
