tpnCC | 2 years ago | on: Methane may not warm the Earth quite as much as previously thought

2nd para beneath the side heading: "Are there alternatives to the 100-year GWP for comparing GHGs?"

GWP calculations has been an active area of research for a long time.

For instance, if you look up the table beneath the VALUES side-heading in https://en.wikipedia.org/wiki/Global_warming_potential, you would notice that from 1995IPCC to the recent one, Scientists are getting more and more closer to ~80 GWP.

tpnCC | 2 years ago | on: Methane may not warm the Earth quite as much as previously thought

There is a detail missing in your Calculation.

Global Warming Potential of Methane over a 20 year Time period is a bit more than 80 times that of CO2. https://www.epa.gov/ghgemissions/understanding-global-warmin...

So, redrawing your path by your method, if we remove ALL of the Atmospheric Methane today, we would be reducing GHG concentrations by about 160ppm CO2 equivalent, which takes the overall CO2 concentrations to less than that of pre-industrial levels(280ppm), 260ppm.

This negates your conclusion that we would hardly observe ANY difference.

If we remove literally all of the Methane today, we would have solved Global warming from the perspective of concentration of Green House gases and will just have to wait and watch for the Global Temperatures to catch up (meaning they will go down).

tpnCC | 5 years ago | on: Ex-Neuralink employees describe rushed timelines clashing with science’s pace

Looks like a misunderstanding.

I think it's likely that OP was genuine and not snarky, Mr.Dang.

As in, since Musk is known to not be 'punctual' as he himself has said in his presentations, since he is known to not have these two in sync 1. Announcement of products with production dates 2. Actual product market release dates, OP may have meant he is surprised Musk seem to be rushing with Neuralink and not delaying as seem to be the case with his other companies.

tpnCC | 5 years ago | on: Coronavirus is most deadly if you are older and male – new data reveal the risks

I'm claiming the high death toll u seem to think of when talking of Flu fatalities ain't that high.

And I provided some evidence for it.

I'm hoping people will not underestimate how serious Covid19 is by drawing parallels to THE NUMBER of yearly Flu fatalities, coz the number of flu fatalities are much less compared to what gets reported every year.

Thts what the SciAm link I provided talks about.

Societies operated WITH a lot of Caution and Precautions in place before the vaccines. They still operate with caution for flu DESPITE vaccines as they do not provide complete immunity.

Look at how people celebrate elimination of Wild polio in Africa! It came AFTER several decades of human suffering and wide ranging precautions.

And the level of caution changes depending on the local medical infrastructure, dynamics of the spread, demographics, and the specific knowledge we have about the disease in question.

I also claimed that WE HAVE SOME IDEA on how to deal with blood clotting wen it comes to Flu. Your link itself shows that out right "Emperic Anticoagulation decreases VTE"

But we are not there yet, when it comes to Covid19.

We have people dying from strokes AFTER they were thought to have recovered from Covid. And these aren't necessarily 'edge cases' that arise from the tail end of large numbers of patients during a pandemic.

These are most likely due to absence of knowledge,data and insights into managing a novel disease. Just read through the NYTimes article. It's very detailed and specific about how we are falling short NOW in dealing with strokes and clots.

Which most likely is also true when it comes to predicting and managing long-term effects due to Covid, as indicated by these experiences of Covid 'long haulers' https://www.theatlantic.com/health/archive/2020/08/long-haul...

tpnCC | 5 years ago | on: Coronavirus is most deadly if you are older and male – new data reveal the risks

"The High annual death toll" is most likely not as HIGH coz the numbers your hear about FLU fatalities are Statistical estimates, unlike that of Covid fatalities. https://blogs.scientificamerican.com/observations/comparing-...

I'm not sure of Human societies operating 'just fine' with the risk of flu. We seem to operate just fine NOW because we make vaccines for the flu every year, and we have several years of experience in terms of Herd Immunity and Medical assistance.

We also do not have medical personnel dying in hundreds from flu every year as they catch it in line of service.

And the baseline of flu u refer to DID NOT HELP much with predicting or managing clots in almost every major organ when it comes to COVID. Sure, we have blood thinners etc. But when u hear from frontline workers in hospitals, the situation with clots is pretty dire. And this is a much bigger deal and the overlap with flu is very little, even in patients tht may seem to have recovered frm Covid. https://www.nytimes.com/2020/05/14/health/coronavirus-stroke...

tpnCC | 5 years ago | on: What if carbon removal becomes the new Big Oil?

The relationship between soot aerosol and warming is complex. Black Soot may dim the sunlight,but may increase the warming by warming the snow.

"A new study found that emissions of soot, or black carbon, alters the way sunlight reflects off snow and may be responsible for as much as 25 percent of observed global warming over the past century."

https://www.nasa.gov/vision/earth/lookingatearth/Black_Soot....

Ash from the volcanoes on the other hand,can cause cooling depending on,among other factors,their composition.

https://climate.nasa.gov/blog/183/

For example, the cooling observed due to Mount Pinatubo is due to Sulphuric Acid aerosol particles.

tpnCC | 5 years ago | on: 'Finally, a virus got me’: Scientist who fought Ebola and HIV reflects

The complete details on the pathophysiology of the disease are far from known yet. For instance "The death of a five-year-old boy in New York of inflammatory complications possibly linked to Covid-19 has prompted Andrew Cuomo, the state’s governor, to warn of “an entirely different chapter” of a disease that had been believed to cause only mild symptoms in children."

"Cuomo later tweeted that there have been 73 reported cases in New York of children falling severely ill with a toxic shock-like reaction that displays symptoms similar to Kawasaki disease."

tpnCC | 5 years ago | on: Coronavirus Causes Damaging Blood Clots from Brain to Toes

In India,one of the slogans of Lockdown is Stay Home,Stay Safe. I think many other countries have urged their citizens to stay at home aswell.

My concern is, if the risk of transmission is more indoors than outdoors as this study indicates(https://theprint.in/health/sharing-indoor-space-major-infect...), Is staying at home making people Vit-D deficient coz of less exposure to sunlight?

And If this is true, is it one of the factors responsible for severe Covid19 outcomes?

Is this also the reason why old folks are severely affected from Covid19, coz they may tend to stay indoors more, relative to other age groups?

tpnCC | 5 years ago | on: Scientists create antibody that defeats coronavirus in lab

"The great bulk of evidence' in this situation would mean the data on the duration of presence of Neutralizing antibodies in the blood stream of people who got rid of the virus. But this data is not there yet,as I said before.

Scientists are currently working to figure out how long the antibodies stay in the body and if they are potent enough to fight re-infections.

There is 'no great bulk of evidence' yet. Unless I'm wrong, and I hope I am.

https://www.thelancet.com/journals/lancet/article/PIIS0140-6... "For any country contemplating these issues, another crucial question is how solid is the assumption that antibodies to SARS-CoV-2 spike protein equate to functional protection?Furthermore, if presence of these antibodies is protective, how can it be decided what proportion of the population requires these antibodies to mitigate subsequent waves of cases of COVID-19?"

"Furthermore, studies in COVID-19 show that 10–20% of symptomatically infected people have little or no detectable antibody."

We need more data, which I understand scientists all over the world are working relentlessly to deliver, to believe that 'you won't reinfect once you get it'

tpnCC | 5 years ago | on: Scientists create antibody that defeats coronavirus in lab

Not exactly. Some hundreds of patients were thought to have gotten rid of the virus during hospital stay and treatment and sent home after confirming through RT-PCR tests. But they were found to be covid+ve afterwards. Studies indicated that the +ve tests were 'likely' from the genetic material that lingered from the first infection and not from re-infection. https://www.livescience.com/coronavirus-reinfections-were-fa... However, they do not declare that you cannot get re-infected two months down the line or two years down the line. We don't have that information about immunity yet.
