The full
effects of the greenhouse gases emitted in 2016 will only be felt in 2030.

The livestock industry notes that if some or most
of the methane could be incorporated into the animal's nutrition processes, rather than being
emitted, this would increase productive weight gain at the same time as cutting
greenhouse gas emissions, for a double bonus
effect.
But the reactive
gases emitted by trees can also increase the amounts
of ozone and methane, both
greenhouse gases which have warming
effects on the climate.
Even allowing for the relative strength
of the
effects, CO2 is still responsible for two - thirds
of the additional warming caused by all the
greenhouse gases emitted as a result
of human activity.
# 102 Kevin: SA claims that «observed
effects of the warming that has already occurred as a result
of the
greenhouse gases we have already
emitted... are already causing massive and costly harm.»
The actual observed
effects of the warming that has already occurred, as a result
of the
greenhouse gases we have already
emitted, are self - evidently already «dangerous» since they are already causing massive and costly harm.
I'd like to stick to facts: * CO2 levels are rising because we
emit CO2 (so we can do something about it) * CO2 is a
greenhouse gas * CO2 thus contributes to warming
of the surface * Other
effects compensate or amplify these changes * Those other
effects haven't reversed / stopped the warming trend yet
Greenhouse Effect: The heating
of the surface
of the earth due to the presence
of an atmosphere containing
gases that absorb and
emit infrared radiation.
While the
greenhouse gas footprint
of the production
of other foods, compared to sources such as livestock, is highly dependent on a number
of factors, production
of livestock currently accounts for about 30 %
of the U.S. total emissions
of methane.316, 320,325,326 This amount
of methane can be reduced somewhat by recovery methods such as the use
of biogas digesters, but future changes in dietary practices, including those motivated by considerations other than climate change mitigation, could also have an
effect on the amount
of methane
emitted to the atmosphere.327
«Notwithstanding any provision
of title III or V, no stationary source shall be required to apply for, or operate pursuant to, a permit under title V, solely because the source
emits any
greenhouse gases that are regulated solely because
of their
effect on global climate change.».
GREENHOUSE EFFECT Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower a
GREENHOUSE EFFECT Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower a
Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most
of the Earth's
emitted longwave infrared radiation, which heats the lower atmosphere.
I believe what is missing from this article and perhaps much
of the work
of many in this field is an equal focus on the cooling
effect of Earthshine
emitting and absorbing (i.e.
greenhouse)
gases.
This figure indicates 3 things: (1) the time lag between
emitting greenhouse gases and when we see the principle
effect is about 30 years, due mostly to the time required to heat the oceans, (2) the rate
of temperature increase predicted by a climate sensitivity
of 3 °C tracks well with the observed rate
of temperature increase, and (3) we have already locked in more than 1.5 °C warming.
More than half
of the global warming observed since 1950 has a human cause, largely from the
greenhouse gas effects of gases such as carbon dioxide
emitted from burning fossil fuels.
When referring to
greenhouse gas emissions, «carbon dioxide equivalent» refers to the amount
of carbon dioxide that would give the same warming
effect as the
effect of the
greenhouse gas or
greenhouse gases being
emitted.
This is because some
of the
gases absorb and
emit radiation at the same frequencies as others, so that the total
greenhouse effect is not simply the sum
of the influence
of each
gas.
