There is no "biology" behind homosexuality. They don't know why people are gay, nor have they found any credible biological links. Still, they have the right to live however they want, even if I do find the stereotypical "flaming homo" annoying.
This depends on what you define "Credible" as. There has not yet been a gene or series of metabolic processes identified that could conceivably result in homosexuality.
However, humans are not the only species who are homosexual. Homosexual (or at least bisexual) behaviors have been observed in plenty of mammals and non-mammals (about 1500 identified, with 500 well studied cases if you want to believe Wikipedia).
If homosexuality were purely a social or psychological construct, then you'd expect not to find it beyond social or psychologically complex animals, but you do.
I'd say there's a credible biological link, but without a mechanism of action the amount of influence is nebulous.
As for climate change, I still call bullshit on this. Scientist are not infallible, 2000 years ago, the science of the day said the Earth was flat, and if you even DARED challenge this notion, you were a laughing stock.
2000 years ago the Scientific Method had not yet become standard. You are correct: Scientists are not infallible, but Science is by far the most effective method we have developed for describing the Universe thus far.
As someone who's actually taken a look at the raw data, and read some open letters from credible scientists (no, not just crackpot wackos)...
I'm going to take a brief moment: Global Warming (or Global Climate Change) is a fact. There is absolutely no doubt about this. Whether or not humans are significantly altering the natural cycles of Warming is what the debate is about.
That said, the vast majority of scientists working in the myriad fields dealing with GCC believe humans have instigated an early cycle. I would be interested to see who your credible scientists are, as there is a Conservative enclave of research scientists under a rather benign title that make good a show of denying APGCC (anthropocentric GCC).
...on top of "Climate Gate", global warming is a sham IMO.
Climate Gate's data was deemed reliable by several unaffiliated scientists. More so, since the study a larger, much more intensive experiment was undertaken that showed the same results and did not succumb to the human errors that Climate Gate did.
This isn't to say we shouldn't START looking after the planet, and that we should put the interests of big oil corporations ahead of the environment, but the biggest problem I have with the whole global warming scare is the fact that food prices have risen substantially as a result of it, starving millions across 3rd world nations.
Again, Global Warming is a fact. The Earth is getting hotter. Every record we know how to accurately read shows this.
The extent of humanity's involvement is what's debated at this point, and what our role is from here on out.
If we do nothing, the Earth will continue to warm at an accelerated rate, and food prices will continue to rise as droughts (like this year's) and more extreme weather events (tornadoes, hurricanes, tsunamis, wildfires) become much more common.
We do not know the full extent or capacity of the Earth's self-regulating mechanisms, but we do have fossil records of mass extinctions which align well with periods of extreme warming - which we're currently on track for.
