The surface temperature of the earth averages about 0. There were two eras of twentieth-century warming, with a slight cooling in between. The first had virtually nothing to do with human activity because incremental increases in atmospheric greenhouse gases, such as carbon dioxide, were exceedingly small.
Instead, the sun got hotter. For unknown reasons the surface then cooled about 0. There is clearly a human component to the latter warming, because it is accentuated in cold, dry regions in the Northern Hemisphere, as is projected by greenhouse-effect theory.
In the Northern Hemisphere, where we have decent temperature histories, central Asia Siberia and northern North America should be prime places to find greenhouse warming. All well and good. But what does it mean?
First, define the threat. Much of this expense has been in the development of models of climate behavior under conditions of increasing greenhouse effect.
There are now dozens of these models. One of the papers that Oreskes must have come across is a landmark meta-analysis of climate models by Gerry Meehl, published in in the Bulletin of the American Meteorological Society. Soon after warming begins it takes place at a constant rate.
The models use the same increase in atmospheric carbon dioxide: But this number is dead wrong and has been known to be wrong for years. The total increase is an effective change in carbon dioxide around 0. Another wonderful aspect of our climate models that Oreskes does not appreciate is that their warming is also very linear with carbon dioxide.
In other words, doubling the rate of carbon-dioxide increase doubles the warming rate. So we have to chop the mean tendency given in the CMIP results approximately 2.
That gives a year warming closer to 1. But why go through all this rigmarole? The CMIP also shows the observed surface temperatures since when the planet began the second warming phase of the twentieth century ; the record is from the IPCC.
Any attempt to explain the warming trend as an upwards curve an exponential warming or a flattening curve fails to add any statistical significance. This is the way science works: Flimsy Straw Person Indeed, Oreskes has set up a profoundly flimsy straw person straw men being politically incorrect.
What does it matter if the planet warms? What is much more important is how and how much, meaning its distribution through the seasons and its rate.
And when one appreciates that the rate is small and the seasonality is disproportionately in the cold time of the year, the impact is lessened even further.
The same process repeats itself in the Arctic that shows up in global and hemispheric temperatures:Annual Report , Ministry of Environment & Forests - Naresh Kadyan - Free ebook download as PDF File .pdf), Text File .txt) or read book online for free.

Pushpa Gujral Science City celebrated World Environment Day in collaboration with the Punjab Pollution Control Board on June 5, involving participation by large number of students in different competitions with an objective to raise awareness amongst students and different segments of the society to protect our environment.
Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer.
The changes are small, so far, but they are expected to grow and speed up. Within the next fifty to one hundred years, the earth may be hotter than it 3/5(7).
