Well, rain is good for the plants which are growing faster and healthier than they were 100 years ago due to the higher level of CO2 in the atmosphere, so as far as the flora of the planet is concerned, things are getting better.
We are in a relatively low level of atmospheric CO2, historically speaking, so as we return to what might be considered a "normal" level, we can anticipate a much more fertile planet. The increased rate of growth, as well as healthier plant growth, should go a long way toward feeding all the herbivores on Earth, including us.
As far as the "R & R" regarding "global warming" -
yes, we have been warming since the end of the Little Ice Age (around the 1700), so it is reasonable to expect us to continue to do so until we reach whatever is the natural "high", at which time we'll continue in some sort of cool/warm cycle. As far back as scientists can evaluate, this is what has been happening. While it is true that we haven't warmed since a recent high in 1998, and have cooled slightly, from what I've read I expect we will resume warming, perhaps in 2015 or 2030 (there is not agreement on how long this slight cooling will last). We had short cooling periods in the early 1900's, again in the '50's, and the "beware of the coming new Ice Age" scare in the '70's. It appears we may be in another one of those.
When will we stop warming? Well, let's look at this chart:
and we can see that we haven't reached previous, recent (in geological terms) high levels, so we may have a way to go.
When you read that we are currently having "all time" highs, you'll notice they say something along the line of "in recorded history". It should be noted that "recorded history" relates to when we started actually measuring temps using instruments and keeping track of these temperatures. This "record" only goes back to early 1800's, I believe, so, yes, since we've been in the recovery from the Little Ice Age this entire time, it is not surprising that we keep having "all time record highs".
As you look at that chart, you'll see some periods of very rapid temperature drops or rises. Look at the period around 900-1000 AD. Doesn't make our recent warming seem anything near "unprecedented", does it?
The main discussion regarding "global warming" shouldn't center around any of these: (as I've said before)
-Arctic Ice disappearing
-Coral reef bleaching
-Mt Kilimanjaro losing snow
-Polar bears doing anything anywhere
-Some creature or plant facing extinction
-A change in cyclones/hurricanes/typhoons
-Computer models or simulations
-Al Gore's movie
-Etc. causing etc. by etc. reported by etc., etc.
because as we continue to recover from the Little Ice Age the best we can do is prepare ourselves for the natural changes that will occur as the planet warms.
The argument regarding "global warming" really centers around what part in the warming we, humanity, plays or effects. In this area the primary area of concern, at least by those supporting the "Global Warming is being caused by man's CO2 emissions into the atmosphere", centers on the CO2 in the atmosphere and whether it causes the atmosphere to warm on a global level and, if so, exactly how much warming does it cause. On this topic the science is no where near settled with some saying it is the dominant cause of recent warming to others saying the amount of warming caused by CO2 is negligible and barely recordable by today's instruments.
This is where the "world's greatest scientists", so to speak, should be debating without any external (political, for example) influence. Remember, increasing CO2 levels are having a positive influence on the planets plant life, so we should be positive that decreasing CO2 levels are something we must do. While one might think that this has already happened, it has not. The media, politicians, certain businesses which will profit heavily, and others have made a concerted effort to make it appear that this has happened, but the truth is that it is not even close to being "settled". Recent disclosures by what is being termed "Climategate" add to this unsettledness by implying that there has been manipulated data and a restriction to the scientific peer review process (among other things) which have both prevented the necessary debate while providing a steady stream of information supporting the Global Warming is being caused by man's CO2 position.
We need honest scientists discussing these things in an open atmosphere.
Then the "R & R" won't stand for "Rants and Raves", it will stand for "Rational and Reasonable".
I'm for that, whatever the outcome.
