Paris Records Its Hottest Day, 108.6 Fahrenheit, as Heat Wave Scorches Europe

https://www.nytimes.com/2019/07/25/worl ... tures.html
Never in recorded history has Paris been hotter than it was on Thursday.

The same was true of Belgium, Germany and the Netherlands, as temperatures rose and records tumbled one by one across Western Europe, scorching the continent and sending residents scrambling to seek relief from a dangerous heat wave.

In Paris, the temperature soared to 42.6 degrees Celsius (108.6 Fahrenheit), breaking a record set in 1947, 40.4 degrees Celsius, according to the French national weather service, which said the temperatures could rise further. Some 20 million people in northern France were expected to be affected by the heat.

In the Netherlands, temperatures topped 40 degrees Celsius (104 Fahrenheit), shattering the record high set only a day earlier, the Royal Netherlands Meteorological Institute said. In Germany, the northwestern town of Lingen hit 41.5 Celsius (106.7 Fahrenheit).

Of course the Swiss weather follows along with high temperatures, but more in the mid 30Cs. We used to ohave a couple of days with 33-35C per summer, but that norm has gone down the draint (assuming we get some rain ;) ). A study of our nightly top summer temperatures has shown a steady rise since the mid 1980s as measured by the number of so called "tropical nights", eg where the temperature does not drop below 20C.

Lost Cities and Climate Change
Some people say “the climate has changed before,” as though that should be reassuring. It’s not

By Kate Marvel on July 29, 2019

Remnants of the ancient city of Cahokia, in what's now southern Illinois.

Not far from my grandmother’s house is a ghost city. At Angel Mounds on the Ohio river about eight miles southeast of Evansville, there are a few visible earthworks and a reconstructed wattle-and-daub barrier. There is almost nothing left of the people who build these mounds; in a final insulting erasure, the site is now named after the white settler family who most recently farmed the land.

There are traces of other dead villages along the Ohio and Mississippi rivers, mounds scattered from present-day Indiana to Arkansas and Alabama. In southern Illinois, a few miles from the Missouri border, hidden among empty corn and soy fields, is the center of that dead civilization’s gravity: the lost city of Cahokia.

Cahokia was larger than London, centrally planned, the Manhattan of its day. Most people there would have come from somewhere else. There were defensive foundations, playing fields, and a magnificent temple. There would have been sacred ceremonies and salacious gossip. It must have been a very exciting place to live.

And then, relatively abruptly, it ceased to exist. We know of the city only because of the physical traces left behind. Few stories of Cahokia have survived; it disappeared from oral tradition, as if whatever happened to it is best forgotten. The archaeological record shows traces of the desperation and bloodshed that almost always accompany great upheavals: skeletons with bound hands, pits full of strangled young women.

Fascinating article. Also terrifying.
“The climate has changed before,” say people who want to minimize the scale of the current challenge. I have never understood how anyone could find this comforting. The natural climate changes that have shaped human history have almost always been smaller and more regionally contained than the large-scale human-caused change we are currently experiencing. And even these changes have provoked suffering, scapegoating, and the collapse of civilizations.

I am often asked what frightens me most about climate change, whether I lie awake at night thinking about ocean hypoxia or arctic permafrost or other feedback processes that could turn a bad thing into a catastrophe. I am scared of the physical changes that await us on a warming planet, but the most important feedback process is the least well understood. The scariest thing about climate change is what it will make us do to each other.

There's a lot more information in the Wikipedia article. https://en.wikipedia.org/wiki/Cahokia While the climate change that occurred caused populations to relocate, more notably abandoning the southwest and places like the area Phoenix occupies today. It doesn't seem like climate change applies to Cahokia. Phoenix was abandoned by the Hohokam after two thousand years of occupation. I have been to the Cahokia Mounds awhile back and was told it collapsed and was thought to be abandoned due to lack of food and sanitation. It did take a few centuries for the area to become too depleted to live. The human sacrifices don't seem to be related to the collapse either. They look like a grand burial of a great chief. Another thing that I find interesting is that the city had 120 mounds, only a few of which were burial mounds.

Off Topic
Even the name is a mistake, the Cahokia people had occupied the city location after the Mississippians had abandoned it.

Collinsville, where the mounds are, is a suburb of St. Louis. During Prohibition, the neighborhood was where St. Louis hit men would dump bodies. The mounds were in a built-up neighborhood which had to be demolished when the site was designated.

Great Barrier Reef health outlook downgraded to "very poor" due to ocean warming https://cbsn.ws/2NGuCHt
The government agency that manages Australia's Great Barrier Reef has downgraded its outlook for the corals' condition from "poor" to "very poor" due to warming oceans. The Great Barrier Reef Marine Park Authority's condition report, which is updated every five years, is the latest bad news for the 133,360-square-mile colorful coral network off the northeast Australian coast as climate change and coral bleaching take their toll.

The report issued Friday finds the greatest threat to the reef remains climate change. The other threats are associated with coastal development, land-based water runoff and human activity such as illegal fishing.

"Significant global action to address climate change is critical to slowing the deterioration of the reef's ecosystem and heritage values and supporting recovery," the report said. "Such actions will complement and greatly increase the effectiveness of local management actions in the Reef and its catchment."

Ever notice that there is never any good climate news? :eek2:

New Global Warming Report Finds ‘We’re All in Big Trouble’

https://www.courthousenews.com/new-glob ... g-trouble/
Climate change is making the world’s oceans warm, rise, lose oxygen and get more acidic at an ever-faster pace, while melting even more ice and snow, a grim international science assessment concludes.

But that’s nothing compared to what Wednesday’s special United Nations-affiliated oceans and ice report says is coming if global warming doesn’t slow down: three feet of sea rise by the end of the century, much fewer fish, weakening ocean currents, even less snow and ice, stronger and wetter hurricanes, and nastier El Niños.

“The oceans and the icy parts of the world are in big trouble and that means we’re all in big trouble, too,” said one of the report’s lead authors, Michael Oppenheimer, professor of geosciences and international affairs at Princeton University. “The changes are accelerating.”

These changes will not hurt just the 71% of the world covered in oceans or the 10% covered in ice and snow, but will harm people, plants, animals, food, societies, infrastructure and the global economy, according to the report by the Intergovernmental Panel on Climate Change.

This popped up in my news feed. UChicago scientists model how cooling atmosphere can tip climate into glacial periods I don't think this is anything new. It's seems to be about the actual mechanics of how small changes in climate would "snowball" into an ice age hundreds of thousands / millions of years ago. I find it interesting because of the increasingly click-bait-ish/inaccurate headlines you can find. It's a study from University of Chicago. Uchicago itself doesn't help with the headline "Antarctic sea ice is key to triggering ice ages, study finds". Cnet has Increase in Antarctic sea ice could trigger an ice age, study finds" which shifts the whole thing into the future tense. Fox puts a cherry on with "Explosion in Antarctic sea ice levels may cause another ice age". That last is the story Google decided to pop up in my feed. Exploding ice. I'm expecting to see another round of youtube videos on this.

Carbon dioxide in Earth's atmosphere reaches record high, researchers say

https://www.nbcnews.com/science/environ ... d_nn_tw_ma
In 2018, global average concentrations of the greenhouse gas, which is a byproduct of burning fossil fuels, reached 407.8 parts per million, which means for every 1 million molecules of gas in the atmosphere, nearly 408 were carbon dioxide. This level is up from the global average of 405.5 parts per million in 2017. The findings follow a trend that shows the planet is continuing to warm at an alarming pace.

“There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris Agreement on Climate Change,” WMO Secretary-General Petteri Taalas said in a statement.

Carbon dioxide traps heat from the sun and can linger in the atmosphere for centuries. High levels of the greenhouse gas are associated with higher global temperatures and other effects of climate change, such as melting polar ice and rising seas.

The level of carbon dioxide in the atmosphere has risen sharply as a result of human activities, with the 2018 global average representing a 147 percent increase over the pre-industrial level in 1750, according to the WMO.

It's sizzling: Australia experiences hottest day on record

https://abcnews.go.com/International/wi ... itter_abcn
The Australian Bureau of Meteorology said the average temperature across the country of 40.9 degrees Celsius (105 Fahrenheit) Tuesday beat the record of 40.3 Celsius (104 Fahrenheit) from Jan. 7, 2013.

“This hot air mass is so extensive, the preliminary figures show that yesterday was the hottest day on record in Australia, beating out the previous record from 2013 and this heat will only intensify,” bureau meteorologist Diana Eadie said in a video statement on Wednesday.

The weather bureau said temperatures in southern and central Australia on Thursday may reach between 8 and 16 degrees higher than normal.

On Wednesday temperatures soared to 47.7 Celsius (118 Fahrenheit) in Birdsville, Queensland, 46.9 Celsius (116 Fahrenheit) in Mandora, Western Australia and similar levels in southern and central Australia.

Fake snow brought to Moscow during warmest December since 1886
Moscow recorded a temperature of 5.6 degrees Celsius (42 Fahrenheit) on Dec.18, breaking a record set all the way in 1886.


https://www.nbcnews.com/news/world/fake ... d_nn_tw_ma
Russia in December is not typically known for its lack of snow. But this winter, the weather is so mild Moscow officials have resorted to bringing in fake snow to put its residents in a festive mood as Russians prepare to ring in the new year.

As the Russian capital experiences the warmest December since 1886, Muscovites have been looking up to the skies with one question on their minds — what happened to traditional Russian winter?

Over the weekend, Moscow authorities said they trucked snow from local ice rinks into the capital, dumping heaps of it in Red Square and landmark streets surrounding it, where thousands of people are expected to gather for the New Year festivities Tuesday.

Some residents expressed their disbelief and amazement at the sight of the artificial snow.

Ocean temperatures hit record high as rate of heating accelerates

https://www.theguardian.com/environment ... ccelerates
The world’s oceans are the clearest measure of the climate emergency because they absorb more than 90% of the heat trapped by the greenhouse gases emitted by fossil fuel burning, forest destruction and other human activities.

The new analysis shows the past five years are the top five warmest years recorded in the ocean and the past 10 years are also the top 10 years on record. The amount of heat being added to the oceans is equivalent to every person on the planet running 100 microwave ovens all day and all night.

Hotter oceans lead to more severe storms and disrupt the water cycle, meaning more floods, droughts and wildfires, as well as an inexorable rise in sea level. Higher temperatures are also harming life in the seas, with the number of marine heatwaves increasing sharply.

The most common measure of global heating is the average surface air temperature, as this is where people live. But natural climate phenomena such as El Niño events mean this can be quite variable from year to year.

2019 Was the Second-Hottest Year Ever, Closing Out the Warmest Decade
By Henry Fountain and Nadja PopovichJan. 15, 2020

Analyses by the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration showed that global average surface temperatures last year were nearly 1 degree Celsius (1.8 degrees Fahrenheit) higher than the average from the middle of last century, caused in large part by emissions of carbon dioxide and other heat-trapping gases from the burning of fossil fuels. That much warming means the world is far from meeting goals set to combat climate change.

“These trends are the footprints of human activity stomping on the atmosphere,” said Gavin A. Schmidt, director of the Goddard Institute for Space Studies, which conducted the NASA analysis. “We know that this has been driven by human activities.”

The average for 2019 was only a small fraction of a degree lower than in 2016, a year with a strong El Niño, when changes in the ocean and air in the equatorial Pacific Ocean led to shifting weather patterns worldwide and pumped a lot of heat from the Pacific into the atmosphere.

Since the 1960s, each decade has been warmer than the previous one, by significant amounts. While the 2010s continued this trend, the second half of the decade was especially warm. The five hottest years ever have occurred during that time span.

World needs to prepare for millions of climate displaced, UN says
Refugees whose lives are threatened by climate change can't be sent back, ruling said

https://www.cbc.ca/news/technology/clim ... -1.5435843
The world needs to prepare for millions of people being driven from their homes by the impact of climate change, the United Nations High Commissioner for Refugees said on Tuesday.

Speaking to Reuters at the World Economic Forum, Filippo Grandi said a UN ruling this week meant those fleeing as a result of climate change deserved international protection, and that it had broad implications for governments.

"The ruling says if you have an immediate threat to your life due to climate change, due to the climate emergency, and if you cross the border and go to another country, you should not be sent back, because you would be at risk of your life, just like in a war or in a situation of persecution," Grandi said.

[highlight=]"We must be prepared for a large surge of people moving against their will," he said. "I wouldn't venture to talk about specific numbers, it's too speculative, but certainly we're talking about millions here."[/highlight]
This is the major issue behind a couple of think tanks' forecast of the coming collapse of society. They postulate that the disruptions caused by climate change (including the flood of refugees) will lead to conflict and countries taking desperate measures to stop the ingress, including closing their borders completely, leading to a siloing of resources. Those with fresh water won't share their water, those will oil won't share their oil. As global trade stops/shrinks and nations are overrun by refugees needing resources, society and governments will break down under the burdens placed on them.
I've heard this bull before.

AP Explains: How climate change feeds Africa locust invasion

https://apnews.com/c89d01fd28ab067ef9bf ... ce=Twitter
Locusts by the millions are nibbling their way across a large part of Africa in the worst outbreak some places have seen in 70 years. Is this another effect of a changing climate? Yes, researchers say. An unprecedented food security crisis may be the result.

The locusts “reproduce rapidly and, if left unchecked, their current numbers could grow 500 times by June,” the United Nations says.

:snippity:

Heavy rains in East Africa made 2019 one of the region’s wettest years on record, said Nairobi-based climate scientist Abubakr Salih Babiker. He blamed rapidly warming waters in the Indian Ocean off Africa’s eastern coast, which also spawned an unusual number of strong tropical cyclones off Africa last year.

Heavy rainfall and warmer temperatures are favorable conditions for locust breeding and in this case the conditions have become “exceptional,” he said.

Ocean Heat Waves Linked to Rise in Whale Entanglements
Whales searching for food near California during recent marine heat events became ensnared in fishing gear

By Bev Banks, ClimateWire on January 28, 2020

Ocean warming has led to more whales being entangled in fishing gear off the California coast, according to research published yesterday in Nature Communications.

The study found connections among changes in forage species from heat waves, a recovery of whale populations and an increased number of whales being entangled in fishing nets.

And the paper proposes an index for assessing the risks to marine life and fisheries' economic stability.

"Warming of the ocean is impacting the ecosystem shift, and so we've had to come up with a new index to better monitor it," said Jarrod Santora, the study's lead author, an ecosystem oceanographer with NOAA Fisheries and an associate researcher at the University of California, Santa Cruz.

Major marine heat waves from 2014 to 2016 reduced offshore krill populations, which left migrating humpback whales hungry and searching for anchovies along the coast near active fisheries.
