Anyone who doesn't believe in climate change is stupid. Anyone who thinks man does not play an important role in climate change is also stupid.

Study blames global warming for 75 percent of very hot days
BY SETH BORENSTEIN AP SCIENCE WRITER
04/27/2015 8:08 AM
Lead author Erich Fischer, a climate scientist at ETH Zurich, a Swiss university, and colleague Reto Knutti examined just the hottest of hot days, the hottest one-tenth of one percent. Using 25 different computer models. Fischer and Knutti simulated a world without human-caused greenhouse gas emissions and found those hot days happened once every three years.
Then they calculated how many times they happen with the current level of heat-trapping gases and the number increases to four days. So three of the four are human caused, the team said.
And when the scientists dialed up the greenhouse gases — using current pollution trends — to simulate a world about mid-century, they got 26 of those super-hot days, "almost a whole month," Fischer said.
The figures that Fischer and Knutti calculated are global estimates. The margins of error, plus or minus about 13 percent with current hot days, grow larger when smaller regions are considered. However, they found Africa and South America now have the highest percentages of unusual hot days that could be blamed on human influence, 89 percent and 88 percent respectively. Europe, at 63 percent, and North America, with 67 percent, come in at the lowest. By mid-century, if emissions continue at current pace, all continents will be able to blame at least 93 percent of super hot days on humans.
"This new study helps get the actual probability or odds of human influence," said University of Arizona climate scientist Jonathan Overpeck, who wasn't part of the research. "This is key: If you don't like hot temperature extremes that we're getting, you now know how you can reduce the odds of such events by reducing greenhouse gas emissions."
Aircraft are far more efficient than automobiles, and there are a lot fewer of them as well.then why is your leader flying around on a big ass jet?
why is your other leader, Al Gore flying around on a G5?
why do you support double standards?
why are you a dumbass?
http://swh.schoolworkhelper.netdna-cdn.com/wp-content/uploads/2011/12/carbon-dioxide-levels.jpg?c71720Global carbon dioxide (CO2) concentrations have reached a new monthly record of 400 parts per million, according to scientists.
The milestone was announced by the US National Oceanic and Atmospheric Administration (Noaa).
They said it was the first month that the entire globe broke 400ppm, reaching levels that haven't been seen for about two million years.
Noaa's Pieter Tans said that reaching the mark was "a significant milestone".
Scientists announced that CO2 had passed the 400 ppm level for the first time in the Arctic in 2012, and then at Mauna Loa in Hawaii in 2013.
"It was only a matter of time that we would average 400 parts per million globally," said Mr Tans, lead scientist at Noaa's Global Greenhouse Gas Reference Network.
He added that CO2 has risen more than 120 parts per million since pre-industrial times.
"Half of that rise has occurred since 1980," he said.
But that's just the weather, right? It's going to change any day now.The last intact section of one of Antarctica’s mammoth ice shelves is weakening fast and will likely disintegrate completely in the next few years, contributing further to rising sea levels, according to a NASA study released on Thursday.
The research focused on a remnant of the so-called Larsen B Ice Shelf, which has existed for at least 10,000 years but partially collapsed in 2002. What is left covers about 625 square miles (1,600 square km), about half the size of Rhode Island.
Larsen B is located in the Antarctic Peninsula, which extends toward the southern tip of South America and is one of two principal areas of the continent where scientists have documented the thinning of such ice formations.
“This study of the Antarctic Peninsula glaciers provides insights about how ice shelves farther south, which hold much more land ice, will react to a warming climate,” said Eric Rignot, co-author of the study and a glaciologist at NASA’s Jet Propulsion Laboratory in Pasadena, California.
The study, published online in the journal Earth and Planetary Science Letters, was based on airborne surveys and radar data.
The study’s lead scientist, Ala Khazendar, said analysis of the data reveals that a widening rift in Larsen B will eventually break it apart completely, probably around the year 2020.
Once that happens, glaciers held in place by the ice shelf will slip into the ocean at a faster rate and contribute to rising sea levels, scientists say.
The study also found Leppard and Flask, two main tributary glaciers of the ice shelf, have thinned by between 65 and 72 feet (20 to 22 meters) in recent years, and the pace of their shrinking has accelerated since the immediate aftermath of the 2002 partial collapse of the ice shelf.

EDIT: Wait, comments were posted while that was being written... I'm torn on the issue, we're coming out of an ice age, sure, but we still might have a significant effect on the CO2 density of the atmosphere, conclusive experiments can't be run, since things like this don't scale in size perfectly, and we don't have a lifesize 'earth" to test on.
Sorry but that is a logical fallacy. Correlation does not imply causation and the fact is there is not 100% correlation here. Populations have increased even through mini ice ages.
