However, given that the overall warming or
heating of the planet continues at a rate equivalent to 4 Hiroshima atomic bomb detonations per second, this framing of the issue is clearly inaccurate and misleading.
Not exact matches
While the
planet's surface didn't warm as fast, vast amounts
of heat energy
continued to accumulate in the oceans and with the switch in the PDO, some
of this energy could now spill back into the atmosphere.
So, overall, the
heating of the entire
planet continues unabated.
But over the long term, as the
planet continues to warm from the increase in greenhouse gases, extended streaks
of heat are
Given that there is continual
heating of the
planet, referred to as radiative forcing, by accelerating increases
of carbon dioxide (Figure 1) and other greenhouses due to human activities, why is the temperature not
continuing to go up?
First, the recent paper describing the threat
of the «aridification»
of a quarter
of the
planet's land area under
continued global
heating implies a critical loss
of agricultural capacity.
If not, might not we want to assume, for the sake
of risk assessment, that this will drive faster break down in the system and faster
heating of the
planet as the ability
of the ocean to support life is diminished, and likely it's ability to
continue to act as a carbon sink?
The basics
of global warming science remain robust — more greenhouse gases will
continue to
heat the
planet, erode ice, raise seas and present challenges to many human and ecological communities.
The fact that you don't understand the mechanisms
of how increased CO2 warms the oceans is irrelevant, since the
heat content
of the oceans is increasing (and, thus, the
planet, as a whole has
continued warming despite your «hiatus»).
After the later, amended version
of the backgrounder was published, the coalition
continued to question the scientific evidence that greenhouse gas emissions could
heat the
planet enough to justify sharp cuts in emissions.
Equilibrium is not reached for many, many hundreds
of years — during which the
planet heats up, and
continues to
heat up for a long while after the extra carbon stops being added.
As the forests burn, and the crops fail, the dangerous buildup
of greenhouse gases will
continue to fuel the
planet towards record
heating, catastrophic sea level rise, and mass methane release.
«Our research revealed warming
of the
planet can be clearly detected since 1873 and that our oceans
continue to absorb the great majority
of this
heat,» said researcher and lead author Will Hobbs
of the University
of Tasmania's Institute for Marine and Antarctic Studies and the Australian Research Council's Centre
of Excellence for Climate System Science.
For instance, there is some hope after Sandy that the press will no longer ignore the monumental scale
of the potential damages to the United States as our
planet continues to
heat up.
That lack
of immediate concern may in part stem from a lack
of understanding that today's pollution will
heat the
planet for centuries to come, as explained in this Denial101x lecture: So far humans have caused about 1 °C warming
of global surface temperatures, but if we were to freeze the level
of atmospheric carbon dioxide at today's levels, the
planet would
continue warming.
Hence, climate engineering is the big temptation
of our times: If there's too much
heat on the
planet, let's block some sunlight and
continue business as usual.
Either the world will
continue to
heat up, or a complex series
of climate changes could tip us over into a sudden new ice age - one so severe, suggests Peter Schwartz, co-founder
of the Global Business Network consultancy, that the
planet's remaining arable land would only be able to support a mere two billion people.
During the talk, I showed the following graph
of the Earth's total
heat content, demonstrating that even over the last decade when surface temperature warming has slowed somewhat, the
planet continues to build up
heat at a rate
of 4 Hiroshima bomb detonations worth
of heat every second.
That a cherry - picked region
of the globe (land exclusive
of the poles) shows little change over a cherry - picked time interval (since 1997 - 1998, strongest El Nino event
of 20th century) does not, in fact, mean the
planet is not merrily
continuing to absorb
heat.
The rapid
heating of the polar regions
continues to accelerate (as is the overall
heating of the
planet), but key western power population centers are miraculously cool.
«Coauthor Felix Landerer
of JPL noted that during the same period, warming in the top half
of the ocean
continued unabated, an unequivocal sign that our
planet is
heating up.»
