“What do you mean, the world is listening?”

I ask the young man.

“That’s what you’re saying,” he replies, referring to the growing concern among scientists that carbon dioxide is making Earth more habitable.

I ask him if he’d ever heard of the phenomenon of the Greenhouse Effect.

“Never,” he says.

The man pauses for a moment.

“I think we should listen to our own voice.”

His comments echo a common refrain from scientists who have been sounding alarms about the impact of CO 2 on the climate.

In a 2013 study published in Nature Climate Change, scientists concluded that the effects of CO-2 emissions on the planet were more than likely the result of climate change, not manmade.

“There’s a growing consensus among scientists and policy makers that climate change is real and that it will have severe impacts on people’s lives,” said Stephen F. Hayes, director of the Center for the Study of Carbon Dioxide and Global Change at Yale University.

“But there’s still an active debate among climate scientists as to what exactly it is that is happening.

We don’t have the data to know.”

The study found that in recent decades, the planet’s climate has warmed about 0.5 degrees Celsius (1.7 degrees Fahrenheit) relative to preindustrial levels.

It also found that CO2 emissions have had no discernible effect on the global climate.

“We have some of the strongest greenhouse gas emissions ever recorded,” said F. Thomas Karl, a climate scientist at the National Oceanic and Atmospheric Administration (NOAA).

“If we continue on that trajectory, we will be warming by a factor of two to three degrees in the next 100 years.”

That’s a lot of CO, even without the Greening effect.

“When CO2 hits the atmosphere, it causes a slight increase in the temperature of the air,” said Hayes.

The CO2 effect has been well documented by scientists in other parts of the world. “

The Northern Hemisphere has a lot more CO2, and that’s where the greatest temperature increase occurs.”

The CO2 effect has been well documented by scientists in other parts of the world.

In the United States, the Green-House Effect has been found to be greater in the Arctic than anywhere else.

In Canada, CO2 concentrations have increased by almost 50 percent over the past two decades.

In Britain, a study found a Greenhouse-Effect of about a degree in the southern U.K. The CO 2 effect is especially pronounced in the Pacific, where CO2 levels are higher than in the equator, where it can take more time for the air to warm.

And the effects are particularly pronounced in regions that experience frequent volcanic eruptions.

The effects can also be felt across the globe.

In Europe, the CO 2 level in the atmosphere is rising faster than it has in the past.

The increase is so dramatic, in fact, that a new report from the United Nations Environment Programme found that the average temperature in Europe is 1.7°F (1°C) warmer than it was in 1951.

“For example, in England, the UK, it is 0.8°F [1.4°C],” said Thomas Karl.

“In Denmark, it’s 0.9°F.”

The climate impact has been seen throughout the world, with the average increase in average global temperatures between 1951 and 2010 occurring 0.4 degrees Celsius above preindustrial averages.

“It’s quite remarkable that we’re seeing this kind of warming and this magnitude of CO effect in the northern hemisphere, when there are so many other effects,” said Andrew Freedman, a professor of earth system science at the University of Arizona.

The effect on food security The CO-H2 effects have also been felt across many other areas of life, including farming and the food supply chain.

A study released in 2015 found that greenhouse gases like CO2 have had a direct effect on crop yields, water use, and soil carbon, and have led to a “greenhouse effect” of increased crop yields.

And while the effects on agricultural yields have been well-documented, the impacts on food safety and the health of food animals have been less well studied.

“Some people are really worried about food security,” said Freedman.

“You can’t make a case for the Green House Effect because it’s not a perfect model for human behavior, but it certainly has a role to play.”

In the years since the Greenhouses Effect became widely known, the United Kingdom has banned the importation of any fruit from countries that do not adhere to the country’s strict organic and local food rules.

In 2015, the European Union introduced its own CO2 labeling system that requires food to be labeled when it’s grown with greenhouse gases, as well as when it comes from the U.S. and Canada.
