Surprisingly, agriculture is the biggest contributor to climate change.

The next big issue, deforestation.

In doing so, we'll be removing a large part of our greatest carbon sink and replacing it with the most high greenhouse gas emission oil in the future.

The air was polluted by exhaust gas.

Inhaling diesel exhaust is bad for our health.

Industrial emissions cause air pollution.

Lows tonight, in the upper forties.

We have the reckless burning of fossil fuels along with other greenhouse gasses, so called,

Let me start with the aspect of comfort, because many people are confusing ambient temperature with thermal comfort.

Then hear this, please.

The control of exhaust gas is especially needed in big cities.

The second pressure on the planet is, of course the climate agenda the big issue where the policy interpretation of science is that it would be enough to stabilize greenhouse gases at 450 ppm to avoid average temperatures exceeding two degrees, to avoid the risk that we may be destabilizing the West Antarctic Ice Sheet, holding six meters level rising, the risk of destabilizing the Greenland Ice Sheet, holding another seven meters sea level rising.

It's six degrees below zero.

Los Angeles weather is clear. Temperature is 72.

Increasing temperature to 480 Kelvin.

Seventyfive degrees.

And I think this is what we've done with climate change.

JOLANKA NlCKERMAN Methane is actually a very potent greenhouse gas.

The temperature fell several degrees.

Yet, the ice of Antarctica is a calendar of climate change.

And they constructed a thermometer of the temperature.

Exhaust gases of a car are noxious.

It's six degrees below zero.

And a weather station is on the structure.

And yet, a bowling ball will always follow the same path.

Los Angeles International Airport in the City of the Angels.

Forecasters are predicting temperatures in the mid90s.

Why do we need to study this anymore?

And that is now what we're trying to do, and working with this large cities group to fight climate change, to negotiate huge, big, volume deals that will enable cities which generate 75 percent of the world's greenhouse gases, to drastically and quickly reduce greenhouse gas emissions in a way that is good economics.

Now, many of the people who participate in Earth Witness would focus on ecological problems, human caused or otherwise, especially environmental crimes and significant sources of greenhouse gases and emissions.

The first way, which is the most important way, is through reducing the emissions from our own operations.

It was a model made before catalytic converters so it'll run good on regular gas.

The exact temperature is 22.68 degrees Celsius.

Our high will get to about 30 today, teens tonight.

The world is buzzing at the moment with plans to force reductions in gas emissions at all costs.

Car exhaust causes serious pollution in towns.
