The mistake in T16 shouldn’t have cost him that much time. It was on the approach to T18, where OCO slowed down to let him past to almost a standstill, causing a yellow to come out and Lando backing off.

Generally yes, but I believe it is best done on a case by case (meaning type of sports, level and skillset) basis.

Generally on the recreational level, the differences between the sexes are much smaller than the differences within one sex. The best example that comes to mind is Tennis. Although it is physical in that it requires a lot of high-speed strength, which theoretically should be an advantage (on average) for young men, the skill difference between a man and another is far greater than that between an average man and an average woman. Go to a public court and you’ll see a non-ignorable amount of women outplaying men (if they even dare to play each other) and what’s even more baffling, older people beating younger people. On the absolute elite level though, they seem to almost play a totally different sport. Ball speed, running speed, ball spin and variety in spin on average are very different on the WTA compared to the ATP and therefore similar but different tactics and even technical styles are employed in the two. The difference within the Top 100 ATP or Top 100 WTA is much smaller than the average Top 100 WTA and average Top 100 ATP. So on that level, imho the segregation is merited.

As some others have already suggested, there might be better criteria to judge this separation on, like with weight class for martial arts. It is not always clear where that divider should be, though. As for tennis: Is it body weight or height? Maybe your fastest or average first serve? Maybe your fastest or average ground stroke? 30m Sprint time? Wherever you put that line might change the nature of the game played in that group and not even eliminate the de facto separation on sex or age, but in turn make it unattractive for some people to engage in a competition in the first place.

Which comes back to my initial statement of judging it case by case depending on the average difference between sexes and the difference within sexes.

edit: replaced gender with sex. Didn’t think of it because in my native language this distinction isn’t made.

Ah ja, dies ist ein weiteres Kapitel des internationalen Rechts - insbesondere Menschenrechte - als Wahlbuffet. Man bedient sich wann und wo es gerade passt und lässt links liegen, worauf man gerade keine Lust hat. Nennt sich Rechtsstaat. \s

Note, that in writing down this post, you haven’t brought forth any objective argument to justify your skepticism. Your argument that because people have agendas, you should be skeptical could be ok if the goal is to get objective information, not form a reactionary opinions.

A strong scientific consensus over this topic is not the result of some political agenda but of the scientific method. One of the central parts of it, is that any claim must be falsifiable through experiment. When anyone comes with a claim, others will try to reproduce or falsify it. Depending on the results the claim is either rejected or used in further research. With vasts of experiments explaining the effect or verifying the effect to better explain what was previously known, a consensus is formed. Politicians are only involved when it comes to appropriating public funding for research. That doesn’t corrupt the research itself, but hinders it if research can’t be done. When industry funds it though, then it does degrade the research very often (see tobacco industry in the 1920s-1980s, the food industry until today, or oil&gas industry which have known about the effects for at least the 1970s through their own research and have not published it).

For some more factual things you can read up on:

That CO2 gets warmer when subjected to light is known since the 1850s when Eunice Foote did experiments with water vapor and CO2 and made this observation and roughly quantified it.

John Tyndall did incorporate this effect into a first, very rudimentary, climate model of the atmosphere in 1862. The global temperature projections of that model for 1950 aren’t perfect, but still astonishingly precise.

Planck in 1900 formulated the Planck Postulate as part of his work concerning black body radiation. Quantization he thought of as a mathematical quirk. Einstein a few years later proposed that the energy of light or photons to be more precise is itself quantized. Einstein got his Nobel Prize in 1923 adopting this to not only explain the Plack Postulate (radiation) but also the photoelectric effect, i.e. that a molecule such as CO2 can absorb energy from the electromagnetic radiation interacting with it.

The scientific community was not convinced of the anthropogenic nature of the warming of the climate until in 1957 Roger Revelle and Hans Suess use the C14-method to show that the ratio of C-isotopes in the atmosphere is shifting towards those of fossil fuels. Since then more measurements have been done using this method to date things and reconstruct atmospheric composition (e.g. through ice-coring).

Since then technology such as satellites have improved the overall quality of measurements. And all of them show a clear tendency. With more computational power climate models have become more powerful and the projections are very good. The differences to measurements, when they happen are usually underestimating because the models are conservatively developed. You can refer to the IPCC reports which show you the data pretty clearly. If you want, then look at data from your local weather station, if it existed over 100 years ago, but even if only 50 years and you’ll probably see a difference even locally. Do that for all stations in the world and you can see a clear trend.

These are only a fraction of topics which anybody can read up on to form an informed decision, rather than opposing something just because it is consensus.

edit: A word.
