The scar high of CO2 concentration in the atmosphere is reminiscent of the great extinction at cause of the Great Extinction of the Permian where catastrophic global warming ended most life on earth.



The findings were published in the journal Geology.

The terminal effects of the weight of the industrial age of humanity has been demonstrated by the observations of the impact of COVID 19 of the human impact that is revealed in the COVID 19 lock down. It is odd that a catastrophy of a world pandemic can have a glimmer It is a lesson on how we may be able reduce and possibly turn the corner on the terminal effects of global warming.

By the evidence we could be headed for a Permian extinction style event oi to the rise in CO2 in our atmosphere and other human effect to the degradation of our environment, which is due to the over population of the world.

Most people are familiar with what are called Ice Caps as the polar Ice Capes. The definition of Ice Capes is where ice sheets begin and and radiate outward. Ice Caps form at differnt places at the poles.

Two million acres burned and still burning, likely a new record.

I saw an expedition to western Alaska I think it was. What a huge undertaking. All to drill down the ice to take the temperature of the water beneath it. I was wanting to route for the people going through such extreme conditions, but just couldn't. To me it was all so pointless.

No matter what humans do or don't do, there is no way imo that it can ever stop global warming/climate change. We can all do something as individuals and as communities and countries for the environment, but nothing we do or do not do will help or hinder climate change as a whole. As if we can somehow stop earthquakes, wildfires, tornadoes, flooding etc etc.

Worshipping at the shrine of climate change is becoming the new religion.

imo caddies no weight in science nor reality.

Trump and Climate Change pulls a Schultz as usual, "We know nothing," combined with fuzzy vague 'arguing from ignorance,' and 'passing the buck.' Trump as with FOX News they ignore the that the Carbon Dioxide content of the atmosphere has been increasing since the Industrial Revolution in proportional to the temperature increase and the increase in droughts around the world between the arid regions and the mesic regions. Much of the Western United States is changing from a mesi region to an arid region with significant rise in temperatures and drop in rainfall.

The Great Barrier Reef has lost half its corals

A new study of the Great Barrier Reef shows populations of its small, medium and large corals have all declined in the past three decades.

Lead author Dr. Andy Dietzel, from the ARC Centre of Excellence for Coral Reef Studies (CoralCoE), says while there are numerous studies over centuries on the changes in the structure of populations of humans—or, in the natural world, trees—there still isn't the equivalent information on the changes in coral populations.

"We measured changes in colony sizes because population studies are important for understanding demography and the corals' capacity to breed," Dr. Dietzel said.

He and his co-authors assessed coral communities and their colony size along the length of the Great Barrier Reef between 1995 and 2017. Their results show a depletion of coral populations.

"We found the number of small, medium and large corals on the Great Barrier Reef has declined by more than 50 percent since the 1990s," said co-author Professor Terry Hughes, also from CoralCoE.

"The decline occurred in both shallow and deeper water, and across virtually all species—but especially in branching and table-shaped corals. These were the worst affected by record-breaking temperatures that triggered mass bleaching in 2016 and 2017," Prof Hughes said.

The branching and table-shaped corals provide the structures important for reef inhabitants such as fish. The loss of these corals means a loss of habitat, which in turn diminishes fish abundance and the productivity of coral reef fisheries.

Dr. Dietzel says one of the major implications of coral size is its effect on survival and breeding.

"A vibrant coral population has millions of small, baby corals, as well as many large ones— the big mamas who produce most of the larvae," he said.

"Our results show the ability of the Great Barrier Reef to recover—its resilience—is compromised compared to the past, because there are fewer babies, and fewer large breeding adults."

The authors of the study say better data on the demographic trends of corals is urgently needed.

"If we want to understand how coral populations are changing and whether or not they can recover between disturbances, we need more detailed demographic data: on recruitment, on reproduction and on colony size structure," Dr. Dietzel said.

"We used to think the Great Barrier Reef is protected by its sheer size—but our results show that even the world's largest and relatively well-protected reef system is increasingly compromised and in decline," Prof Hughes said.

Climate change is driving an increase in the frequency of reef disturbances such as marine heatwaves. The study records steeper deteriorations of coral colonies in the Northern and Central Great Barrier Reef after the mass coral bleaching events in 2016 and 2017. And the southern part of the reef was also exposed to record-breaking temperatures in early 2020.

"There is no time to lose—we must sharply decrease greenhouse gas emissions ASAP," the authors conclude.

Oh. Is it already time to move from the covid myth back to the climate warming myth? I thought we would have several more months before that happened.

It is obvious that you are deep into conspiracy mythology, and anti-science.

Nothing changed. We we have global warming as we have for centuries since the industrial revolution as CO2 content in the atmosphere has increased. The CO2 content in the atmosphere is now higher than ever recorded in recent geologic history. The evidence has determined the rate of global warming is accelerating.

Is that right? You find that CO2 is a pollutant when it is what plants thrive upon? You have forgotten the most basic science. Get a life. Produce life. Produce CO2

Too much CO2 also insulates the atmosphere and prevents heat from escaping, basic science = global warming.
