Orbits of Jupiter and Venus Affect Earth's Climate, Says Study (usatoday.com)
According to a new study published in the journal Proceedings of the National Academy of Sciences, gravitational tugs from the planets Jupiter and Venus gradually affect Earth's climate and life forms. The phenomenon occurs every 405,000 years and has been going on for at least 215 million years. USA Today reports: Jupiter and Venus are such strong influences because of their size and proximity. Venus is the nearest planet to us -- at its farthest, only about 162 million miles -- and roughly similar in mass. Jupiter is much farther away, but is the Solar System's largest planet. The study says that every 405,000 years, due to wobbles in our orbit caused by the gravitational pulls of the two planets, seasonal differences here on Earth become more intense. Summers are hotter and winters colder; dry times drier, wet times wetter. At the height of the cycle, more rain falls in the tropics, allowing lakes there to fill up. This compares to the other end of the cycle, when seasonal rains in the tropics "are less and lakes have much less of a tendency to become as full," [study lead author Dennis] Kent said. The results showed that the 405,000-year cycle is the most regular astronomical pattern linked to the Earth's annual turn around the sun, he said. Right now, we are in the middle of the cycle, as the most recent peak was around 200,000 years ago.
No, it doesn't. What it does is show amazingly well how desperately some people will cling to anything in order to explain away things they don't want to take responsibility for with some ridiculously irrelevant theory rather than deal with the facts which demands a change in behaviour.
The mere idea that these planets would have greater influence than us pumping the atmosphere full of known greenhouse gasses is outright moronic. But of course people like you jump for it, because you get to say "the dog ate my homework!", or in this case "it was all the planets fault, we can't do anything about it so let's party and forget about the whole thing." Because that's the kind of retard you are.
Of course it doesn't. But it helps to explain why, *hundreds of years ago when science barely existed*, intelligent people could take astrology seriously.
The sun has a massive effect on us, the moon too (light, tides). So why couldn't the other heavenly bodies effect us?
And they do effect us. But since then, science has managed to quantify that effect. And that effect, it turns out, consists of gravity and pretty much nothing else. Very occasionally, like in this study, that gravity has noticeable effects on our lives.
Challenge to your assertion: have, in the past, been periods with much higher concentrations of CO2 and simultaneously a thriving ecosystem?
(The answer is 'yes')
Challenge to your assertion: did that ecosystem have 10 billion humans in it, largely living in the places which were flooded back then but not now?
(The answer is 'no')
Natural climate changes takes hundreds of thousands of years, about the amount of time it took for humans to become distinctly humans.
They do? Ice covered most of the Northern US just 12,000 years ago, during the last glacial period. Oceans were ~100 meters lower back then, too... Now we're being warned about maybe a meter over 100 years (about the same rate of change as we've seen since the last glacial period) and that it's doomsday!
