Neither do you understand tipping points, nor neither does climate science understand tipping points. They are hypothetical constructs without the slightest shred of actual evidence for support. They are fear mongering at its worst.
Backradition, if you think it is happening is entirely a matter of belief. Belief in the face of physical laws that state explictly that it can not happen. For me backradiation belongs in the realm of the tooth fairy, elves, and hobbits. For ther to be a greenhouse effect as claimed by climate science, one must "believe" in backradiation which clearly can not happen if you place any creedence at all in the physical laws.
Are you familiar with solar ovens? Parabolic dishes that when pointed at the sun get very hot very quickly and focus the sun to a small point which can be used to heat water rapidly? If you like, I can point you to a web site that will provide you plans to build one very cheaply (less than 25 dollars). A solar oven can provide observable, repeatable proof that backradiation is not happening. I have done the experiment numerous times with scout troops and school groups.
You place a thermometer at the focal point in your solar oven and point it at a clear sky away from the sun. Watch the thermometer. During the day, the temperature will drop between 3 and 5 degrees precisely as the second law of thermodynamics predicts. If backradiation were happening, as you believe, the backradiation would be directed to the focal point and the temperature would increase by some small degree. If you point your solar oven into a clear night sky when the ambient temperature is 45 degrees or less, but above freezing, you can, as the second law of thermodynamics predicts, cause ice to form in a cup placed at the focal point in the solar oven. ICE forming when the temperature is as high as 45 degrees. Climate science describes backradiation as a phenomenon that happens 24 hours a day. If there were backradiation sufficient to warm the surface of the earth, how might ice form in accordance with the second law of thermodynamics when the ambient temperature is more than 10 degrees above the freezing point?
The fact bob, is that there is no such thing as backradiation and the belief in it is a matter of faith, not science.
Actually, I provided you with a perfectly acceptable scientific web site, and a reproduction of an experiment which disproves the quaint 19th century experiment upon which most of modern climate science is based. And the experiment was never intended to disprove backradiation, it was intended to prove that the glass in a greenhouse is not trapping IR radiation but merely preventing convection and conduction. The laws of physics disprove backradiation, but if that isn't good enough for you, the above experiment with a solar oven will provide you with actual observable, repeatable evidence that backradiation is not happening.
Absolute malarky. How many species extinctions can you point to that are due to climate change. Do provide credible links.
Since most of the present species in the oceans evolved at a time when atmospheric CO2 was several orders of magnitude greater than the present, there is nothing to worry about. As to the upwellings from the deep oceans, acidity isn't the problem but rather a lack of oxygen which is in no way due to climate change. Your oyster example is just not valid as you are describing problems farmers are having trying to grow a non native species presumably in the northwest as that has been recently in the news. The "upwellings" you describe are having no ill effect on the native species, but are causing problems with the non native speices that are being farmed in the region.
Scaremongering is not science.
