Sea level rises far greater for coastal communities, scientists find

Study is first to analyse global sea-level rise combined with measurements of sinking land

Coastal populations are experiencing relative sea-level rise “up to four times faster than the global average”, which threatens many megacities located on deltas, according to research led by the University of East Anglia (UEA).

The research is the first to analyse global sea-level rise combined with measurements of sinking land. The impact of subsidence combined with sea-level rise caused by climate change “has until now been considered a local issue rather than a global one”, it concludes.

The study published on Monday in Nature Climate Change found coastal inhabitants are living with an average sea level rise of 7.8mm to 9.9mm per year over the past 20 years, compared with a global average rise of 2.6mm a year.

The impacts are far larger than the global indications previously reported by the Intergovernmental Panel on Climate Change (IPCC) – the UN body whose research is undertaken by leading climate scientists.

Global heating pushes tropical regions towards limits of human livability

Rising heat and humidity threatening to plunge much of the world’s population into potentially lethal conditions, study finds

Should governments fail to curb global heating to 1.5C above the pre-industrial era, areas in the tropical band that stretches either side of the equator risk changing into a new environment that will hit “the limit of human adaptation”, the study warns.

Humans’ ability to regulate their body heat is dependent upon the temperature and humidity of the surrounding air. We have a core body temperature that stays relatively stable at 37C (98.6F), while our skin is cooler to allow heat to flow away from the inner body. But should the wet-bulb temperature – a measure of air temperature and humidity – pass 35C, high skin temperature means the body is unable to cool itself, with potentially deadly consequences.

“If it is too humid our bodies can’t cool off by evaporating sweat – this is why humidity is important when we consider livability in a hot place,” said Yi Zhang, a Princeton University researcher who led the new study, published in Nature Geoscience. “High body core temperatures are dangerous or even lethal.”

"Should governments fail to curb global heating to 1.5C ...".
They're well past failing - waiting on the lag. There's easily another 1.5 C baked in & we ain't finished.

I don't blame governments for emissions, since all life operates by the dictates of the MPP. Where they've failed is not preparing & protecting tax paying citizens. We have no choice in using all available energy, but there's no law that says how we must use all of it.

The only thing I've seen federally in N America is the Canadian & American governments move a handful of home owners to a new & safer locals because they were repeatably getting flooded out (AGW Jacked).

Can't realistically expect sensible action from declining nations with ever more dysfunctional & corrupt law makers & bureaucrats. Look to yourself.

The standard expectation is that the wet bulb temperature hitting levels which mammals can't survive will be the onset of the problem. This is not correct since even short lived spikes into this regime will do heavy damage and such transients will grow in intensity and duration long before any full transition into the non-habitability regime.

There is clearly not going to be any serious action on global warming in the next 10 years. By the 2030s we should start to see the occurrence of serious agricultural damage on a sporadic basis. By the 2050s there will be terminal failure of prime agricultural zones on the planet. The research for this already exists. Given the overly optimistic view of global warming progression and consequences from such research in the recent past, these conclusions cannot be fobbed off as alarmist and are likely wrong on the optimistic side.

Figure 11 (corrected at the end) for the sc_PDSI_pm (self-calibrated Palmer Drought Severity Index and Penman-Montieth) blended metric. Values under -3 are sever droughts. The period 2060-69 is shown but it is already dominated by severe drought regimes on an annual mean basis. Severe droughts every three years would already do in agriculture so severe problems will arrive before 2050.

The key detail that escapes a lot of people is that we are seeing a lagged response. The warming today is not all there is to the current greenhouse gas burden. It takes several decades for the full effect to kick in. At the rate of CO2 increase we are seeing now, we are guaranteed to see over 500 ppmv by 2050. That is simply catastrophic.

Extremes

142-year-old record broken by massive temperature turnaround in Minnesota

Within the span of just a few weeks, the city of Minneapolis has experienced low temperatures that challenged a daily record low set 146 years ago, and now, has broken a daily temperature record that stood for 142 years.

On Feb. 14, temperatures dipped all the way down to 19 degrees below zero Fahrenheit at Minneapolis-St. Paul International Airport, just missing a record low temperature for the date originally set in 1875.

But now just three weeks later, city residents are dressing for a very different record. On March 9, the city reached a high temperature of 62 F, shattering the previous high-temperature record of 61 F for the date in the city last reached in 1879.

Locust outbreaks in the Horn of Africa are linked to the changing climate

As rainfall increases, plagues expected to rise in frequency

Since 2018, swarms of desert locusts have devoured vital crops and vegetation in the Horn of Africa, and scientists are drawing ominous links between this new reality, the warming climate and increasingly extreme weather.

“Unusually heavy and widespread rainfall has made this plague more serious, impacting countries that had previously been hardly affected, such as Kenya, South Sudan and Uganda,” says Christiaan Kooyman, a scientific advisor and biopesticide expert in Kenya. “It is fairly certain that climate change has contributed.”

The locust plagues are linked to powerful recent cyclones in the fast-warming western Indian Ocean, with the heavy rains, strong winds and soaked land creating ideal conditions for desert locusts to breed and spread.

The frequency and intensity of these cyclones are increasing. A recent commentary in the journal Nature Climate Change noted that 2019 was a record-setting year for the number of tropical cyclones in the Indian Ocean, with eight making landfall. As part of this, the capital of Djibouti received the equivalent of two normal years’ worth of rain in four days. Across the Red Sea, desert lakes formed in a barren, uninhabited region of Saudi Arabia known as the “Empty Quarter.”

Siberia's warming shows climate change has no winners

In the Republic of Sakha in far eastern Siberia, the temperature is minus 50 C, yet white smoke rises from the snow-covered ground. In January, local media released an amazing image of a peat fire in the ground under the snow.

Roughly 140,000 sq. km of Russia, about the size of Greece, was lost to fire in 2020. Most of that was in once-frozen areas. When covered with snow in winter, the fires seem to be extinguished. However, the peat in the ground continues to smolder, and in summer it ignites on the surface. They're being called zombie fires and are believed to be caused by global warming.

There are concerns that the zombies will rage again this year.

Peat fires emit large amounts of carbon dioxide. A record 244 million tons of CO2 equivalents were released by fires near the Arctic Circle, mainly in Russia, in the 12 months through last August, according to the British journal Nature. That is 35% more than a year earlier and equal to 21% of Japan's total emissions in 2017.

In Siberia, plants and other organisms that have been decomposing for more than 10,000 years are trapped in the soil as CO2 and methane gas. These gases are released by fires and other events, further accelerating global warming. The world's permafrost zones are thought to contain twice the amount of carbon that is in the atmosphere.

There is another phenomenon that illustrates the seriousness of the situation.

Last summer a craterlike hole with a diameter of 20 meters and depth of 30 meters was discovered in the permafrost zone of northwestern Siberia. It is the 17th such hole to be discovered since 2014. The working hypothesis is that the craters are the result of explosions of accumulated methane gas in the thawing permafrost. The blasts are able to blow away frozen soil that had been contained by ice.

This might be fine so long as no one is living in these locations. But in May 2020, a fuel tank at a power plant on the outskirts of the city of Norilsk in central Siberia collapsed, spilling diesel fuel into a nearby river. It caused such serious environmental damage that Putin declared a state of emergency.

The operating company concluded that the collapse occurred because the ground loosened as the permafrost thawed. It has been reported that one-fifth of the infrastructure in the frozen zone, including oil and gas facilities as well as railroads, will be affected by 2050.

In 2016, western Siberia experienced a different kind of crisis, an anthrax outbreak. One boy and over 2,000 reindeer died. The source of the bacterial infections was the melted corpse of a reindeer that had been frozen for more than 75 years. Some scientists have warned of the possibility of more dormant pathogens reactivating.

Russia ratified the Paris Agreement in September 2019. The base year for reducing greenhouse gas emissions is 1990, just before the collapse of the Soviet Union. Since its emissions have declined rapidly since then, Russia has already met its short-term target.

Although it was supposed to be a global warming "winner," Russia has become an unexpected climate change victim.

244 Mt/0.21 = 1.162 Gt

Global emissions in 2017 of CO2 alone were 37.1 billion tons according to

https://ec.europa.eu/jrc/en/news/global ... eased-2017

According to

https://stats.oecd.org/Index.aspx?DataSetCode=AIR_GHG

Japan released 1.289 Gt in 2017 and not 1.162 Gt. But the real issue is that Japan has offshored its CO2 emissions via manufacturing in China and other countries.

Humans remain the primary source of CO2 emissions by far. This article tries to spin Siberian peat fires as if they are super important. No they are not.

[JuanP]

I both want and expect all the permafrost in the world to melt and all the peat in the world to burn, and, hopefully, make the planet uninhabitable for the human species along the way.

These are not new problems. We've known this shit would happen since forever. Russia will be just fine, it has a stable population, it is the biggest civilization nation state in the world by far, it is mostly virgin land, it has more natural and mineral resources than any other country in the world, it has enough weapons to defend itself from anyone in the world, including the USA, it produces more food than it consumes, and it produces more energy than it consumes. If there is one country in the world that is in a good position to confront the predicaments facing humanity, that country is Russia. They will very likely last longer than anyone else.

JuanP, I think our purpose is to live the good life longer than anyone else. After that, sure let the Russians have it

There will be a lot of desperate immigrants from the Caucasus / Middle East, Central Asia and China coming to have their share of those abundant resources.

There already are. Russia is second only to the USA on the number of immigrants it receives, but the populations of Russia's neighbor's are mostly already declining or beginning to decline.

That is really old news! Is that the best you can do? A nine months old article on one oil spill from an anti fossil fuels Western website that promotes clean energy and EVs? That is essentially a propaganda article against Russia and fossil fuels!

Everybody here knows that Russia will pay a heavier price from melting permafrost than any other country in the world. That hasn't been news for decades. I have no doubt that the Russians will adapt and survive, just like they've been doing for over a thousand years.

You remind me of someone from the Ozarks who was always digging negative stuff about Russia and China for one reason or another. Anyway, thanks for the link; it had some nice drawings.

[dissident]

Typical western hate spew. As if the melting of permafrost exists only in Russia and is 100% Russia's responsibility. Western haters are some of the most demented imbeciles on the planet. Melting of Canadian and US (Alaska) permafrost must be emitting negative CO2 and helping to fight global warming. LOL.

2017 CO2 emissions from Russia were 2.155 Gt. The CO2 emissions from the USA were 6.488 Gt.

It is primarily US and foreign CO2 emissions that are responsible for Siberian permafrost melt.
