” Positive feedback loops may release ever increasing amount of greenhouse gases” says a recent study by the UK met office released in oxford.
This is the same met department which had earlier predicted ‘a barbecue summer’ for 2009, “warmest year ever” for 2007 and “milder and drier than average winters” for last year for UK. All these “little” predictions proved to be way off-target. The summers in UK were not even closest to an averagely warm summer in UK, the begining of 2007 witnessed a plunge in global temperatures by 0.7 degree C and the last winters were one of the chilliest observed in few years.
Now feedback loops can be the reason which may lead to a 4 degree C rise in global temperatures by 2055, if the emissions are not reduced reveals the study.
The study comes at a time when the internet media is abuzz with talks of a ‘pause’ in the global warming phenomenon. The ‘pause’ has been accepted by the scientists but reasons are being given for the sudden lull in the phenomenon. Hundreds of anti-global warming blogs have become active and the reduced warming is being celebrated by anti-anthropogenic warming proponents and the counterparts have gone into what appears to be a hibernation to strike back with more “unprecedented” reasons.
With this little post I start writing some concrete stuff down here. What I will not write is about the common scare being forecasted but i will try and find out reasons for theories being put forth.
It has come to my notice that far away from our so called ‘Milkyway galaxy’, large and small bursts of matter are taking place. Each large burst is equivalent to ‘one cosmic life’ while the small ones are equivalent to 61yrs. Small bursts are not a new or unkown phenomenon for earthoids but seldom had any one imagined large bursts.
After the first few tests of the little available data about these bursts, scientists are trying to figure out whether ‘positivity elephants’ are the reason behind it.
This simple tool from SPPI (Science and public policy Institute) helps you find out the manmade warming at anytime in future. The excerpt below has been taken from july report on co2 by SPPI.
“‘Here is a step-by-step, do-it-yourself ready-reckoner which will let you use a pocket calculator to make your own
instant estimate of global temperature change in response to increases in atmospheric CO2 concentration.
STEP 1: Decide how far into the future you want your forecast to go, and estimate how much CO2 will be in the atmosphere at
that date. Example: Let us do a forecast to 2100. The Monthly CO2 Report charts show CO2 rising to C = 575 parts per
million by the end of the century, compared with B = 385 parts per million in late 2008.
STEP 2: Next, work out the proportionate increase C/B in CO2 concentration. In our example, C/B = 575/385 = 1.49.
STEP 3: Take the natural logarithm ln(C/B) of the proportionate increase. If you have a scientific calculator, find the natural
logarithm directly using the “ln” button. If not, look up the logarithm in the table below. In our example, ln 1.49 = 0.40.
STEP 4: Choose a climate sensitivity coefficient c from the table here
STEP 5: Find the temperature change ΔT by multiplying the natural logarithm of the proportionate increase in CO2
concentration by your climate sensitivity coefficient. In our example, we’ll chose the SPPI central estimate c = 2.50 F. Then –
ΔT = c ln(C/B) = 2.50 x 0.40 = 1.0 F°, your predicted manmade warming to 2100. It’s as simple as that!”
