The radiative forcing from these changes in concentrations can be easily calculated using standard formulas (from Etminan et al, 2016 which supersede the slightly simpler ones from IPCC TAR), as about 2 W/m 2 for the CO 2 change and 0.65 W/m 2 for CH 4. W/m<sup>2</sup> (to about 60% of the CO 2 effect since 1750).

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,

The data, available for free online, can help track air quality indicators, heavy metals in air, dust, and other atmospheric components which can affect human health.

The district court ruled that EPA was required to conduct such evaluations in October 2016 and set an expedited schedule for EPA’s compliance. 451962/2016 (N.Y. The standards and guidelines were published on August 29, 2016. The magistrate judge’s order also set the trial to begin on February 5, 2018. June 16, 2017).

The developing science of climatology with its understanding of the need for chemistry made scientists concerned for the future on seeing masses amounts of carbon released into the atmosphere (8) , but also (as it was previously) regarding trees as a resource and the potential for depletion.
