translation: 'i can't stand it when you debunk my denier cult bs with clear, easily readable scientific facts so i'm going to quibble about your use of fonts even though it makes me look very stupid'.
that is what you got out of that?
of course. You ignore the information presented and go off topic on a rant about my use of larger fonts.
That's a pretty idiotic misunderstanding of what was said. Have you already forgotten how this interaction started?
orbital changes? What orbital changes are you talking about? Are you just spouting nonsense because you think everyone is as stupid as you?
i was responding to another denier cult twit when you hopped in with your ignorant disbelief that the climate had ever been influenced by "orbital cycles" so i posted some info on the milankovitch cycles for your edification, not to debunk your denialist position. Doubting the influence of orbital cycles just reflects stupid ignorance, not a specific "
denialist position".
i have actually said on multiple occasions that climate change is real, and that humans are contributing to it. I just see no reason to go apeshit over something just because it is happening now instead of a few thousand years in the future, and absolutely scoff at the idea that it will result in a massive extinction event.
the climate patterns are changing because the earth is getting hotter and the earth is getting hotter because humans have pumped hundreds of billions of tons of fossil carbon into the atmosphere, raising co2 levels 40% over the pre-industrial levels that had stayed within a very limited range for several million years. Humans aren't just
contributing to global warming and its consequent climate changes, we are
causing it. You are a denier.
You again show your complete ignorance of this topic with your assertion that what is happening now would happen anyway in "
a few thousand years. Utter nonsense and completely backwards. The earth was on a long, very slow pattern of declining temperatures that would have eventually, in thousands of years, taken the planet into another period of heavy glaciation, or ice age, similar to the one that ended about ten thousand years ago. Our co2 emissions have reversed that course and the world is now headed for conditions not seen on this planet for tens of millions of years.
last time carbon dioxide levels were this high: 15 million years ago, scientists report

you would have to go back at least 15 million years to find carbon dioxide levels on earth as high as they are today, a ucla scientist and colleagues report oct. 8 in the online edition of the journal science. "the last time carbon dioxide levels were apparently as high as they are today and were sustained at those levels global temperatures were 5 to 10 degrees fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the arctic and very little ice on antarctica and greenland," said the paper's lead author, aradhna tripati, a ucla assistant professor in the department of earth and space sciences and the department of atmospheric and oceanic sciences.
you can "
scoff all you want (that's what deniers do, after all) at the fact that agw is going to cause extinction events but the science is very clear and the extinctions have already begun.
mass extinctions linked to climate change are already underway.

maclean, imd and rj wilson, 2011. Recent ecological responses to climate change support predictions of high extinction risk. proceedings of the national association of sciences http://dx.doi.org/10.1073/pnas.1017352108.
new evidence confirms what scientists have long suspected: That climate change is already having major effects on many of the world's species. Researchers report for the first time that the documented species responses migration to a higher or cooler climate or changes in population suggest actual extinction risks linked to climate change are almost double those that were predicted. Just as grim are future outlooks almost one-third of species will be threatened by 2100. Temperature, ocean acidity and other climate-related changes can set the stage for widespread extinctions by adding even more pressure to ecosystems already stressed by habitat loss, pollution, disease and other human-related impacts.
