Not at all, you idiot asshole. Why don't you do a little research instead flapping your stupid yap with zero evidence to back your bullshit.Human Impacts on Climate
The Earth's climate is now clearly out of balance and is warming. Many components of the climate system--including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons--are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6°C over the period 1956--2006.
As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.
During recent millennia of relatively stable climate, civilization became established and populations have grown rapidly. In the next 50 years, even the lower limit of impending climate change--an additional global mean warming of 1°C above the last decade--is far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2°C above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, and--if sustained over centuries--melting much of the Greenland ice sheet with ensuing rise in sea level of several meters. If this 2°C warming is to be avoided, then our net annual emissions of CO2must be reduced by more than 50 percent within this century. With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections.
American Geophysical Union Revises Position On Climate Change
The American Geophysical Society's statement on global warming. Unequivocal statement. The AGU has more climate scientists among it's members than any other Scientific Society in the world. But you ignoramouses think that you know more than these scientists. And most of your yammering is based on the rants of an obese junky on the AM radio, or the spews of a fake British Lord. LOL
We are leaving the last ice age you stupid fuck
Now a new study hopes to settle the issue by arguing that data points to the fact that Earth's climate has been warming over the past 10,000 years - long before human activity is thought to have changed the climate.

A study last year (shown by the blue lines) said that temperatures in the Holocene maximum (8000 – 9000 years ago) - cooled by 0.5°C. But climate models (yellow and black) suggest that the planet should have gradually warmed by about the same amount during that period
It argues that previous research that showed a cooling trend was wrong because it used contradictory ice core data.
The research was undertaken by University of Wisconsin-Madison's Professor Zhengyu Liu.

Note that we peaked out at about 8000 years ago, and have slowly been declining until the start of the Industrial Revolution. That is in agreement with the Milankovic Cycles.
