This seems to be the new trend now a days…lets blame everything on Global warming….

Everything from the heat wave in Paris to heavy snows in Buffalo has been blamed on people burning gasoline to fuel their cars, and coal and natural gas to heat, cool and electrify.

BJP lost election…..blame it on global warming

I mean come on… you guys are reasonable intellectual people.. aren’t you..

Ice age…remember ice age? well even the movie will help

Earth has been hit by 4 ice ages

There have been at least four major ice ages in the Earth’s past.

The earliest hypothesized ice age, called the Huronian, was around 2.7 to 2.3 billion years ago during the early Proterozoic Eon.

The earliest well-documented ice age, and probably the most severe of the last 1 billion years, occurred from 850 to 630 million years ago (the Cryogenian period) and may have produced a Snowball Earth in which glacial ice sheets reached the equator^[26], possibly being ended by the accumulation of greenhouse gases such as CO₂ produced by volcanoes. “The presence of ice on the continents and pack ice on the oceans would inhibit both silicate weathering and photosynthesis, which are the two major sinks for CO₂ at present.”^[27] It has been suggested that the end of this ice age was responsible for the subsequent Ediacaran and Cambrian Explosion, though this theory is recent and controversial.

Causes of ice ages

The causes of ice ages remain controversial for both the large-scale ice age periods and the smaller ebb and flow of glacial–interglacial periods within an ice age. The consensus is that several factors are important: atmospheric composition (the concentrations of carbon dioxide, methane); changes in the Earth’s orbit around the Sun known as Milankovitch cycles (and possibly the Sun’s orbit around the galaxy); the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on the Earth’s surface, which affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth-Moon system; and the impact of relatively large meteorites, and volcanism including eruptions of supervolcanoes.

Some of these factors influence each other. For example, changes in Earth’s atmospheric composition (especially the concentrations of greenhouse gases) may alter the climate, while climate change itself can change the atmospheric composition (for example by changing the rate at which weathering removes CO₂).

Maureen Raymo, William Ruddiman and others propose that the Tibetan and Colorado Plateaus are immense CO₂ “scrubbers” with a capacity to remove enough CO₂ from the global atmosphere to be a significant causal factor of the 40 million year Cenozoic Cooling trend. They further claim that approximately half of their uplift (and CO₂ “scrubbing” capacity) occurred in the past 10 million years.^[33][34]

So what we learn from this is that there have been 4 ice eages in the past and NONE of them have been caused by human beings…

So I am pretty sure that the next ice age will not be a fault of Human beings either.

See there is not enough data to predict global warming.Think about it for a second.Human beings have been on earth for only 200,000 years

Mitochondrial DNA and fossil evidence indicates that modern humans originated in Africa about 200,000 years ago.^[4] Humans now inhabit every

Now the Industrial revolution started some where in 18th century and has gone on till now,approximately  200 years.

So lets get somethings straight right away

Humans in their 200,000 years of existence on earth have ruined the atmosphere of the earth?

The age of earth is accepted to be around 5 billion years, so

200,000/5000000000

So Humans have only inhabited 1/25000th of the total life span of the earth.

Hmm…okay …. the Industrial revolution started only in 200 years…so that reduces it to 1/25000000 the of the earths total life span.

And this in this fraction to the time spent by human beings on earth…we manged to trigger a global warming ?

Well that is an achievement by the human race.If true we should be proud of it.

let me draw this number game a little further

Do we have data for all the 200,000 years that we have survived on this planet. Well no… Okay SO what data do we have….We only have data for last 30 years at the best.

30/2500000000 of the data we have and we are off predicting global warming and Ice age.

I keep telling people that we do not have enough data to predict if we are warming up for good or warming for bad,if at all if it is caused by humans.

Human beings as a race will come to extinction, just like the dinosaurs , Did dinosaurs die of global warming ? No.

May be we will be hit by a meteorite or some zombie like dieseas, but for sure it will not be global warming.

The glaciers in the artic ocean are melting at an alarming rate….we should worry ….. I ask why…not very long ago  they were plain grass lands where mamoths would graze peace fully, they froze to death in a sudden instance where

Why would the woolly mammoth, bison, woolly rhinoceros, and horse be attracted to Siberia? Today, Siberia is a barren, blizzard-scourged wilderness. How could the animals have endured the extremely cold winters? What would they eat? Where would the beasts locate the prodigious quantities of water they require when the land is imprisoned in snow and ice? Even the rivers are covered with several feet of ice every winter. Most puzzling of all is how did the mammoths and their companions die en masse and how could they have become encased in the permafrost?Over time, various clues about the environment at the time of their death have been discovered and studied. Scientists found partially preserved stomach vegetation in some of the carcasses and so could identify the woolly mammoth’s last meal. Solving one mystery just leads to another. They wondered how the stomach contents remained half decayed while the animals froze? This is a problem since it takes a long time to freeze an animal as large as an elephant. A quick freeze came to mind. Birds Eye Frozen Foods Company ran the calculations and came up with a staggering –150°F (–100°C). Once again, the scientists were puzzled. How could such temperatures be reached on earth, especially when apparently they were in a fairly temperate environment before the quick freeze?

Many theories have been postulated. One of the most popular is that the hairy elephants were peacefully grazing on grass and buttercups and were suddenly struck by a huge freezing storm blowing from the Arctic Ocean. Millions of them froze instantly. This kind of quick freeze has never been observed, so some special and imaginative ideas have been proposed

So What ever hit the poor grazing mammoth killed it instantly, it was actually chewing the grass when the cold breeze hit it and froze it.It wasn’t global warming which killed it.

To be continued.
