Scripps Oceanography and NOAA announced this week that average levels of carbon dioxide in the atmosphere exceeded 411 parts per million in May. That’s a new record. And their studies show that the rate of CO2 increase is accelerating. To read more visit here.

It would have been far simpler if they just said "You Die!" as reason enough. Far too late anyway.

I think this whole issue of social justice re: CC is ridiculous. It is not India or the US or whatever country that is warming it is the entire planet and we do not get to chose which areas will be most affected. Nature will do that. We lost the chance to enact any social justice when we passed 2 billion or so and now that we have destabilized the PLANETS climate. As for attempts to adapt, well I do not expect anybody to come to the rescue of anybody else. At best people sharing local areas will help each other. When finally WE emerge from the bottleneck, things may begin to be better for the survivors but the going through it will be analgous to a woman giving child birth quite quite painful.

More Persistent Weather Patterns in US Linked to Arctic Warming

Jennifer A. Francis et al, North American weather regimes are becoming more persistent: Is Arctic amplification a factor?, Geophysical Research Letters (2018)

Abstract
Rapid Arctic warming is hypothesized to favor an increased persistence of regional weather patterns in the northern hemisphere [Francis and Vavrus 2012]. Persistent conditions can lead to drought, heatwaves, prolonged cold spells, and storminess that can cost millions of dollars in damage and disrupt societal and ecosystem norms. This study defines a new metric called long‐duration events (LDEs) ‐‐ conditions that endure at least 4 consecutive days ‐‐ and takes two independent approaches to assessing seasonal changes in weather‐pattern persistence over North America. One applies precipitation measurements at weather stations across the United States; the other is based on a cluster analysis of large‐scale, upper‐level atmospheric patterns. Both methods indicate an overall increase in LDEs. We also find that large‐scale patterns consistent with a warm Arctic exhibit an increased frequency of LDEs, suggesting that further Arctic warming may favor persistent weather patterns that can lead to weather extremes.

Plain Language Summary
Rapid Arctic warming and sea‐ice loss are expected to affect weather patterns around the northern hemisphere. An increased persistent of weather regimes is one hypothesized impact. Long‐lasting weather conditions can lead to destructive extreme events, such as droughts, prolonged cold spells, heatwaves, and flooding. This study uses daily precipitation measurements across the United States, as well as daily large‐scale atmospheric patterns over the eastern Pacific and North America, to assess changes in weather‐regime persistence, and whether any changes are associated with a rapidly warming Arctic. We find an increased frequency in long‐lived patterns in recent decades, especially those with abnormally warm high latitudes, suggesting that further Arctic warming may favor an increase in extreme events caused by prolonged weather conditions.

Scientists at Rutgers University-New Brunswick and the University of Wisconsin-Madison examined daily precipitation data at 17 stations across the U.S., along with large upper-level circulation patterns over the eastern Pacific Ocean and North America.

Overall, dry and wet spells lasting four or more days occurred more frequently in recent decades, according to the study published online today in Geophysical Research Letters. The frequency of persistent large-scale circulation patterns over North America also increased when the Arctic was abnormally warm.

"While we cannot say for sure that Arctic warming is the cause, we found that large-scale patterns with Arctic warming are becoming more frequent, and the frequency of long-duration weather conditions increases most for those patterns," said Francis, who works in the School of Environmental and Biological Sciences.

The results suggest that as the Arctic continues to warm and melt, it's likely that long-duration events will continue to occur more often, meaning that weather patterns—heat waves, droughts, cold spells and stormy conditions—will likely become more persistent, she said.

"When these conditions last a long time, they can become extreme events, as we've seen so often in recent years," she said. "Knowing which types of events will occur more often in which regions and under what background conditions—such as certain ocean temperature patterns—will help decision-makers plan for the future in terms of infrastructure improvements, agricultural practices, emergency preparedness and managed retreat from hazardous areas."


Researchers Find Precipitation Thresholds Regulate Carbon Exchange

... Ecosystems either soak up carbon through photosynthesis—a negative feedback that could reduce future warming—or release it through respiration—a positive feedback that could enhance future warming. Understanding how climate change might impact ecosystem photosynthesis and respiration is critical for predicting future carbon dynamics.
"This study suggests we know more about the negative feedback loop and less about the positive one."

Liu's team discovered that whether ecosystems across the U.S. uptake carbon or release it is dependent on water availability. The primary control switches from production to respiration at an annual precipitation threshold between 30 and 35 inches in the contiguous United States. The carbon balance of ecosystems in the dry West is very sensitive to photosynthesis. In contrast, the carbon balance of more mesic Eastern U.S. ecosystems is more sensitive to carbon lost through respiration.

However, climate models do not reflect this precipitation threshold. Liu and his co-authors determined that these models are far too sensitive to photosynthesis and not sensitive enough to respiration, suggesting the Earth's ecosystems may lose more carbon to the atmosphere in the future as surface temperatures continue to warm.

Alterations To Seabed Raise Fears for Future

The ocean floor as we know it is dissolving rapidly as a result of human activity.

Normally the deep sea bottom is a chalky white. It's composed, to a large extent, of the mineral calcite (CaCO3) formed from the skeletons and shells of many planktonic organisms and corals. The seafloor plays a crucial role in controlling the degree of ocean acidification. The dissolution of calcite neutralizes the acidity of the CO2, and in the process prevents seawater from becoming too acidic.

But these days, at least in certain hotspots such as the Northern Atlantic and the southern Oceans, the ocean's chalky bed is becoming more of a murky brown. As a result of human activities the level of CO2 in the water is so high, and the water is so acidic, that the calcite is simply being dissolved.

The McGill-led research team who published their results this week in a study in PNAS believe that what they are seeing today is only a foretaste of the way that the ocean floor will most likely be affected in future.

Jet stream dipping way south...check out the map at the link below.

Of course the jet stream has dipped way south before, but what I find notable is the erratic behavior of the jet stream, one week drawing hot air north, creating a heat wave in the US, and then the next week drawing record-breaking cold air south in the US. Not to mention the 2nd record-breaking heatwave to hit Europe this summer.


Record Cold in July: Unusually Strong Midsummer Cold Front Refreshes Plains, South

https://weather.com/forecast/regional/n ... ains-south



  • A cold front has taken an unusually far southward plunge by late-July standards.
  • This has brought cooler, less-humid air as far south as parts of the Gulf Coast and Texas.
  • Daily record-low temperatures may be set through Friday morning.

Or even daily forecasts are imperfect. 20% chance of rain is NOT 0% chance of rain. (I used to assume 20% chance meant it wouldn't rain, and that generally worked. But the occasional isolated shower would give you a good soaking on your bike.)

That says NOTHING at all about the reality of global warming. The persistent global warming we're seeing decade after decade isn't just "chaotic", it's a clear trend which science can tell us a lot about, re the overall cause.
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.

KJ thinks that because forecasters can't always predict exactly when and whether it's going to rain all the time, therefore no one can be at all sure whether the months of December, January and February are likely to be colder or warmer than the months of June, July and August in the mid latitudes of the Northern Hemisphere.

It would be laughable, if it weren't clear that the guy is clearly capable of thinking more clearly than that, so much be assumed to be intentionally trying to delude the unwary.

The education system never introduced them to the energetics of climate. They have no clue that the geophysical fluid system (atmosphere including ocean and land water) is subject to energy constraints. All they know about is what they can feel on their skin, the particular weather state realizations. It is beyond them, that these weather states are constrained by the global energetics of the system.

They are utterly clueless about the massive energy uptake by the system over the last 60 years with 90% going into the oceans. Until the only thing that they are aware of, the instantaneous weather state behaviour, becomes wildly different from what they experienced before, they will not understand that the system is changing on a massive scale and in a long duration persistent way.

Such clueless people are always fixated on variability. The energetics exhibit vastly less variability than the weather states they experience.
