Sentences with phrase «known effects of greenhouse gases»

Some of these forcings are well known and understood (such as the well - mixed greenhouse gases, or recent volcanic effects), while others have an uncertain magnitude (solar), and / or uncertain distributions in space and time (aerosols, tropospheric ozone etc.), or uncertain physics (land use change, aerosol indirect effects etc.).

Of these gases, known as greenhouse gases, water vapour has the largest effect.

Due to the fact that much of the Earth is covered in oceans, and it takes a long time to heat water, there is a lag before we see the full warming effects of an increase in atmospheric greenhouse gases (this is also known as «thermal inertia»).

Your expperiment measures the heat capacity of greenhouse gases and not the greenhouse effect, sorry no sale.

Even if the earth's temperature had stayed the same or even decreased slighty over this time, ask yourself this: given what we know about the greenhouse effect and the levels of CO2 gases the world is creating, would you not be concerned that if we continue at the current rate, things are gonna get a hotter, eventually?

If we include reasoned deductions from what we know of the Sun and climate in the past, we must allow that solar changes could potentially alter the anticipated effects of carbon dioxide and other greenhouse gases on the surface temperature of the Earth.

The rapid warming since 1970 is several times larger than that expected from any known or suspected effects of the Sun, and may already indicate the growing influence of atmospheric greenhouse gases on the Earth's climate.
