Global warming :: is it just a 'chinese hoax' like trump told us or is it serious?

IPCC report continued...

Just operating the existing fossil fuel infrastructure — the oil and gas wells and pipelines, the coal mines and the coal- or gas-fired power plants for the rest of their natural lives — puts 1.5°C limit out of reach! 

And if every currently planned fossil fuel project is completed, it would only guarantee that the world warms more than 2°C.  

To stay below 1.5°C, the use of coal around the world must be virtually eliminated by 2050, according to the IPCC, and oil use must decrease by at least 60% and gas by 45%.

and replaced with what?

@KellyM_1964

There you have it, CNN.  Oh well.

even on a good day   that is bad news for us

The IPCC states that

fast, deep cuts to methane emissions are essential
to getting warming mitigation on target.

     Methane is a long-overlooked but powerful greenhouse gas,
and emissions of it are rapidly rising as natural gas displaces coal
and demand for meat grows.

(Methane is emitted when natural gas leaks instead of being burned,
and it is a byproduct of the digestive process of farm animals.)

Methane much more than gas leaks and farm animals. Micro organisms known as Methane formers produce much of the world's methane.

We're doomed!!!!

Interesting fact rarely mentioned; Methane is only flammable from 5% to 15% by volume in air. Less than 5% it will not burn, over 15% it will not burn.

To stay below the critical mark of just +1.5°C rise,

carbon dioxide emissions must fall by 48% by 2030
and by 80% by 2040;

methane emissions must fall by 34% by 2030 and 44% by 2040.

China says go ahead and get going, we'll make sure we PEAK carbon emissions around 2030 and the end carbon emissions by 2060.

Insert "Ostrich with head in sand" emoji.

the world isnt moving on this with any urgency at all

in fact some argue that we r already past the point of being able to keep it under 1.5c unless we start a very aggressive program using technology to remove co2 from the atmosphere      

I wish it would but it won't. Not until it's far too late to reverse most of the damage.

Special presidential envoy for climate John Kerry hailed the IPCC report as a call to action.

“The stakes are clear,” Kerry said in a statement.
“Complacency will be met by irreversible and unthinkable impacts
from climate change. Every country must move further and FASTER.

He's absolutely right but I still don't think we will get anywhere close.   The economic calamity as a result will be enormous, and right here in USA.

IPCC report continued...

" Faster means rapidly upscaling deployment of renewable energy.
Faster means targeting methane emissions.
Faster means reducing demand and focusing on efficiency.
Faster means halting and reversing global deforestation.
Faster means demanding more sustainable transit.
The IPCC report is a reminder that mitigation is NOT about cost,”
Kerry argued.

“It is about investment — in our future,
our children’s future, and our planet’s future. ”

I hate to be forced to agree on this but actually it's all going to get a lot worse.    This is some very serious shite.

“This report tells us we are not doing enough to cut greenhouse gas emissions,” said United Nations Environment Program Executive Director Inger Andersen at a press conference on Monday morning.
“The solution has to be to kick-start the transition to renewable and cleaner sources of energy. Increased action must begin this year, not next year, this month, not next month, not tomorrow. Otherwise, we will continue, as the secretary-general warned, to sleepwalk into catastrophe.”

kerry is 100% correct     but its not likely we will achieve that goal

Odds of extreme Atlantic hurricane seasons
DOUBLED by climate change, study says

Scientists say that the influence human-induced climate change
is having on the Atlantic tropical cyclone season is becoming
increasingly clearer and a new peer-reviewed study published
in Weather and Climate Dynamics reports that sea surface
temperatures have doubled the chances of extremely active
Atlantic tropical cyclone seasons.

Data collected from 1982-2020 revealed that an extremely active
Atlantic tropical cyclone season was made 200 per cent more likely
in 2020 due to warming ocean temperatures.

Warmer oceans result in a greater amount of water vapor in the
atmosphere, which feeds tropical cyclones and hurricanes and
can result in heavier and more destructive rainfall.
Over 90 per cent of excess heat created by greenhouse gases
have been absorbed by the world’s oceans since the 1970s.

NOAA states that many studies indicate that in a scenario where
the planet is 2°C warmer than pre-industrial temperatures, there
will be up to a 15 per cent increase in rainfall rates averaged
within 100 km of a tropical cyclone.

Lake Mead plummets to unprecedented low,
exposing original 1971 water intake valve

(CNN)

  The West is in the grips of a climate change-fueled
megadrought, and Lake Mead -- the largest manmade
reservoir in the country and a source of water for millions
of people -- has fallen to an unprecedented low.

The lake's plummeting water level has exposed one of the
reservoir's original water intake valves for the first time, officials say.

Science journal Nature reveals that climate change can increase the risk of more pandemics in the future.  At least 10,000 virus species have the potential to infect humans.  Currently, the vast majority circulate silently in animals.  However climate change could force animals to flee habitats, increasing the risk of virus spread from animals to humans.  Some animals end up in food markets.  Investigations found natural origin of covid pandemic to be more plausible than virus leak from Chinese lab.  Reality tends to be less diabolic.

Lake Mead has three "straws" (intake pipes) that draw water. The now exposed 1971 first straw sits 173' below the high water mark at 1,050' above sea level. Straw #2 built in 2002 is 50' deeper at 1000'. Straw #3 is an 24' tunnel bored under the lake and sits at 890' above sea level or now at 150' below the surface. Cost was over 800 million dollars.

The whole problem with the Coloado Basin is too much water allocation. From its headwaters in the Rockies, the Colorado River meanders 1,400 miles through five states and into Mexico, nourishing 40 million people and irrigating 5.5 million acres of farmland along the way. Despite decades of subsequent development, the water rights first established by the Colorado River Compact in 1922 remain essentially unchanged today. The agreement allocates 15 million acre-feet each year (picture an acre of land covered with a foot-high layer of water) among the seven Colorado River Basin states: Wyoming, Utah, Colorado, New Mexico, Nevada, Arizona, and California. The compact also acknowledged Mexico’s right to water, and in 1944, the nation was guaranteed 1.5 million acre-feet, bringing the total to 16.5 million. For many years, states rarely took all they were owed; currently, the river can’t come close to meeting demand.

Interesting that this isn't the first time the Basin has seen drought. Tree ring analysis reveals a six decade drought in the 1100's.

So what caused the dead carp and brown foam back in early June of 2013???

I was there and I solved this puzzle. 

The human-caused climate crisis is supercharging rainfall in hurricanes, scientists report

(CNN)
The rainfall from hurricanes during the deadly, record-breaking 2020 season was as much as 11% higher because of the human-caused climate crisis, scientists reported Tuesday.

The study, published in the journal Nature Communications, found global warming supercharged hourly rainfall rates in tropical storms and hurricanes by 5 to 10%.

When they looked at only hurricanes the increase was 8 to 11%.

very intresting
