the numbers on shark attacks

Leave a reply

This article in Grid says there are about 70 shark attacks on humans per year, worldwide. That’s attacks, not deaths. This article doesn’t have the death numbers, but I recall seeing elsewhere that it is typically single digits. And it’s not because sharks are not around where people are swimming – they are.

Humans are pathetic in the water. If sharks wanted to eat them, it would be so easy for them. If they tasted good and a shark were like, “Oh, my goodness, there is a human, let me have a bite,” there would be between 10,000 and 50,000 bites a day. There’s a lot of sharks in the ocean and a lot of people that are recreating there.

We don’t see that. We see very few, about 70 a year. And although there are 70, more than half of them are in poor visibility water where the shark makes a mistake. So the fact that the bites that we do see are where conditions are turbid and where people happen to be intersecting with where there are sharks sort of underscores the notion that sharks do not eat people — we aren’t on the menu.

So if we are trying to be rational, we shouldn’t even worry about sharks, even compared to other things that can and do go wrong in the water, most obviously drowning.

linking climate change to inflation?

Leave a reply

This book review in the Guardian tries to link climate change to inflation. It talks about the costs of storms, fires, and insurance, and impacts of heat on worker productivity. I’m not convinced it is exactly on the mark. Cleaning up from storms can actually stimulate the economy, if they have only local impacts and don’t happen too often. One area’s cost of cleanup creates business and jobs for another area of the economy. The larger economy should be able to absorb these costs if it is healthy. Maybe this is the issue – are the impacts of storms, fires, and floods become geographically widespread and frequent enough that they are taking up a significant amount of our economy’s productive capacity that could be better spent elsewhere? Maybe that is the case, but this article doesn’t address it. I can certainly imagine this being the case if and when major population centers (and economic drivers of our economy) start to be impacted on a regular basis by a combination of severe storms and sea level rise. A major earthquake or volcano could have similar impacts, and while it would have nothing to do with climate change directly, it would happen on top of climate change and we need to be ready for the known risks let alone the unknown ones.

The article doesn’t talk much about food, but along with impacts on coastal cities, a tightening of the food supply relative to population seems like the most obvious and immediate impact of climate change on people. While climate change didn’t cause the Russia-Ukraine war, removing food exports from those two countries from the system has taught us something about how tight the food supply is. Climate change could add up to a similar tightening over a period of time, and remove that slack that we currently have in the system. And then shocks can and will happen on top of the long term trend. It really does not seem like the world is ready.

Project Syndicate Predictions for 2022

Leave a reply

Wow, a dozen or more famous people asked to weigh in and it is almost 100% doom and gloom. To grossly summarize:

  • Carbon emissions will just keep getting worse, and not much will be done. About the most positive thing anyone can say is that pressure for change will increase and the “corporate and financial sectors” will get more serious about it. We are the corporate and financial sectors, and we are here to help!
  • Political dysfunction and polarization in the US and EU. Republicans will retake the US Congress (and both sides will say they knew it all along).
  • US vs. Russia, China vs. US, Iran vs. the US and/or Israel. Several commentators predict one more attempt to revive the Obama nuclear deal, which will fail, which will be followed by more uranium enrichment, which will be followed by a military strike by the US and/or Israel.
  • Bees will continue to decline. Does this seem less important than the other things? Bees pollinate around a third of crops, and even if we find other ways to pollinate crops or grow crops that don’t need pollination, we can look forward to:

Given that heatwaves, droughts, floods, and other extreme weather events prevent people from engaging in agricultural work, and that bees and other pollinators affect 35% of the world’s agricultural land and support the production of 87 of the leading food crops, we will see an increase of global insecurity, even in developed economies. Unable to sustain the production of the food they need, many of the world’s poor will be pushed into extreme poverty, suffer malnutrition, and migrate.

  • Several point to mass migration as a big issue for 2022. Not a long term issue, but an issue that will come to a head in the next year.
  • On the Covid front, most people think it will just become another disease that kills us some times but we will get used to that.
  • Many commentators think inflation will tone down, and that the bigger risk is governments overreacting to it. Some predict a sharp decline in the US dollar (is this bad for the average Joe? hard to say), and there is already a real estate crash happening in China.
  • A few are optimistic that social safety nets may improve here and there.
  • On the technology front? “One hopes for more demonstrations of the power of recent biomedical and genetic research, amply validated by the rapid development of safe and effective COVID-19 vaccines. There also may be new leaps in additive manufacturing and machine learning.” (Diane Coyle) There may be some progress on “green hydrogen and an overhaul of mobility and transportation systems”.

I’m not known for unbridled optimism, but let me think of a few positive things that could happen in 2022. Electric vehicles could finally emerge in the public consciousness in the US. We will all be surprised if that happens, and then one day later we will all have known it all along. The US could make some progress on the childcare crisis that is holding our country back (see this Fresh Air interview if you don’t believe me). Covid will be annoying and disruptive, but I am predicting it will be less annoying and disruptive on December 31, 2022 than on January 1.

In a way, a good year at this point will be one in which nothing really catastrophic happens and we have some breathing room to chip away at the many challenges already on our plates. We have to hope there will not be a major war, nuclear detonation, epic new plague, major food crisis, catastrophic meltdown of the internet or financial system. Hoping is about all us average citizens can do about the latter list, but if you are one of the movers and shakers out there with the power to help manage these risks, WHAT ARE YOU DOING???

I tried to talk myself into being optimistic just now, and failed, oh well.

clean up that air and get those fat asses moving!

Max Roser has one of his nice data-based articles focused on air pollution. There are a variety of estimates, but they fall within a fairly narrow range (considering the population of the world) of about 7-9 million people per year. Something like 2-4 million of this is estimated to be due to indoor air pollution, which is a big problem in the developing world. The biggest source of the problem is…wait for it…particulates from burning fossil fuels.

He compares these numbers to around 75,000 deaths per year from terrorism and war combined, 500,000 from homicide (I’m rounding to the nearest 100,000, and he doesn’t provide numbers for suicide which I would guess could be similar or higher), 1.3 million for road accidents, and 2.8 million for obesity.

So if you were a politician (or emperor) who wanted to help the most people, you would make this a big priority, along with reducing deaths in and around motor vehicles and deaths from all the sitting around we do. What do these all have in common? We need to work toward electrification and clean energy, sure – but using 100% existing knowledge and technology, we can design safer streets and roads using the designs we (okay, a few Europeans, at least) already know work, and encourage people to live near work and shopping where they can mostly get around by their own muscle power, supplemented by good public transportation. Or to be much more crude, get those fat asses moving and those lungs out in the healthy, fresh air! Every dollar transferred from the defense/security budget to these things would pay off something like 8:1. And that is in the short term, if a thing called global warming caused by burning fossil fuels did not even exist.

October 2021 in Review

Most frightening and/or depressing story: The technology (sometimes called “gain of function“) to make something like Covid-19 or something much worse in a laboratory clearly exists right now, and barriers to doing that are much lower than other types of weapons. Also, because I just couldn’t choose this month, asteroids can sneak up on us.

Most hopeful story: The situation with fish and overfishing is actually much better than I thought.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: I thought about how to accelerate scientific progress: “[F]irst a round of automated numerical/computational experiments on a huge number of permutations, then a round of automated physical experiments on a subset of promising alternatives, then rounds of human-guided and/or human-performed experiments on additional subsets until you hone in on a new solution… [C]ommit resources and brains to making additional passes through the dustbin of rejected results periodically…” and finally “educating the next generation of brains now so they are online 20 years from now when you need them to take over.” Easy, right?

gain-of-function research

According to Vanity Fair, a lab in New York collaborated with the Wuhan Institute of Virology to “enhance a bat coronavirus to become potentially more infectious to humans”. I personally don’t care about the “lab leak hypothesis” at this point. It is clear that this type of research is common now and probably happening all over the world. It needs to be tightly monitored and controlled or we may be in for a bleak future.

“Disease X”

Are you worried that nobody is prepared for the next big pandemic? Have no fear, there is a group preparing to “advise the WHO on developing a framework to define comprehensive studies” about that. And after that, the WHO is going to be “developing policies and enhancing preparedness” about it. I am sure this will not take very long!

It seems like the UN and the WHO should be the organization to lead this effort globally, and creating new bodies in parallel would be redundant and counter-productive. But the UN approach did not seem to work very well this last time around. There are also the intertwined risks of natural pandemics, biological warfare and biological terrorism that need to be dealt with, and the WHO does not seem to be the agency to deal with these as existential threats. It seems to be more about representing the world’s under-represented people and countries at the table where these things are discussed.

In the U.S., our existing agencies (CDC, customs, FEMA, etc.) did not deal with this threat effectively. Again, nobody wants to just make new redundant agencies, and nobody wants to just turn the thing over to the military industrial complex. But it seems like we need to do something. Maybe this is why Obama created the “white house office of pandemic whatever” to try to coordinate or at least understand all this. Not a new parallel agency, but a new layer of oversight or at least a watchdog. The government grows this way, and the new growth may be healthy, but we never prune out the dead underbrush.

asteroids can sneak up on us

Leave a reply

I have been putting asteroid strikes in the category of potentially catastrophic but so rare as to not worry about. I have also assumed we would see a really big one coming for decades if not centuries and would at least have a chance to get organized and do something about it (a big if, given the lack of coordinated international response to climate change and the pandemic.) But according to this Jerusalem Post article, a fairly sizable asteroid could sneak up on us by passing close to the sun on its way to us. This happened on September 16, 2021 with an asteroid somewhere in the 50-100 m diameter range. The article doesn’t do the math on what size conventional or nuclear weapon this would be the equivalent of if it hit. I thought that was pretty standard…

The article has an interesting (and chilling) photo of the 2013 Chelyabinsk asteroid streaking in, which was about 17 m wide. The article says that on April 13, 2029, a 340 m asteroid is supposed to “safely pass by” the earth at a distance of “under 32,000 km”. Assuming the article has the number right, that is only about one-tenth the distance from the Earth to the moon. This sounds like one to watch.

Covid-19 probably wasn’t made in a lab, but something like it could be at any time

This Atlantic article is about a grant proposal to artificially create something very close to Covid-19 in a laboratory. Not to worry, it was not funded and it does not prove or disprove the “lab leak hypothesis”. Wait a minute, regardless of the lab leak hypothesis, what is chilling here is that the technology exists to create a Covid-like bioweapon or something even worse in a laboratory right now. This does not particularly surprise me, but it is scary. Even if we assume scientists in leading countries like the U.S. and China are relatively well regulated and have relatively high ethical standards, somewhere in the world there will be experts who are not as ethical and people willing to fund them. And over time, the technology will become more accessible to more people. And garage biotechnology will be harder to monitor and control than nuclear technology.

If I were spinning conspiracy theories here, I would say isn’t it an interesting coincidence that U.S. laboratories are set up to genetically engineer a Covid-19 if they want to, and U.S. laboratories also happened to have the vaccine for Covid-19 pretty much developed and ready to commercialize when needed. Hmm…I have no evidence of this and am not saying it is likely, I am just saying it is a story that would not be inconsistent with reality.
