Higher ed must lead climate change adaptations

Higher Education institutions play a key role and must be leaders in preparing society to adapt to the needs of a changing climate, according to a new report evaluating education, research, campus sustainability and public outreach.

It boils down to leading by example in working to mitigate the challenges posed to society by a and creating opportunities in new and more sustainable technologies, said the University of Arizona's Jonathan Overpeck, a member of the national committee that produced the report and one of world's leading experts on and policy.

"So often our society is reactive; we're trying to make it as proactive as we can and position our state and country in the lead in what will become a much bigger driver the world's economy, meeting the climate change challenge," said Overpeck, co-director of the Institute of the Environment and a professor of and atmospheric sciences.

Published by the American College and University Presidents' Climate Commitment, the report calls on higher to create campuses that are safe and secure in the face of change, more actively engaged in solving real-world problems and reorganized to better provide the education and research needed to create and maintain a .

The UA is cited in the report for its "varied and extensive research in adaptation to climate change," with specifics projects including "developing adaptation-planning frameworks, understanding consumer choices and their collective impact on the adaptive capacities of communities, and conducting experiments on the resilience of forest and rangeland ecosystems to climate changes to help inform adaptive management of natural resources."

Beyond this expansive and interdisciplinary world-class research are efforts at green initiatives and on campus, a wide range of course offerings to educate the next generation of citizens and leaders on scientific and policy issues related to climate change and solutions, and active, ongoing partnerships with society at large, including lawmakers, community leaders and business sectors.

"We're certainly laying down a challenge to everybody, particularly our peers in universities, to do this," Overpeck said. "It's amazing that there are some strong universities around the country still not paying much attention to climate and creating sustainable campuses. A large member of many communities across the county, universities can not only set an example, but they can help others achieve higher levels of sustainable practice."

Overpeck hasn't slowed down his research and advocacy, even on sabbatical. A recent visit to a Chinese university highlights the urgency in forging a new path ahead.

"The genie is out of the bottle in China. The universities are now encouraged to talk about environmental issues, to talk about climate change and to push themselves and their communities to do what needs to be done.

"That's good news because it means China will rapidly become a partner in solving the global climate challenge we have, but it's also a challenge in economic terms because China knows so well that it can be the world leader in economic gains from providing solutions.

"I see it positioning itself to become a major competitor to provide knowledge and technological solutions for the future, and I worry that in America, with the political polarization that exists around the issue, we will falter. This is a matter of economic strength and national security in becoming leaders in solving the climate change challenges."

The more that I watch the "debunking collective" try to have its way, the more that I have come to think of it as a gestative stage of intellectual development which only a small fraction of the population eventually emerges from. We all come from this same place, due to the way in which we've all been educated through rote memorization. It's easy to see through for many of us, because the debunkers rarely have much of use to say about differentiating authentic from pseudo controversies. That's because they have largely abandoned philosophy of science -- which is not only the very tool they need to make that distinction, but also the tool which generated the textbook theories which they now profess allegiance to.

The debunkers offer the world a faith-based approach to science, because their faith in scientific consensus -- by necessity -- far exceeds their actual knowledge. It is a form of obscurantism, because they would have us decide controversies without exploring them.

I wonder who is BSing the most. If Denver is any kind of city they very well could have protected their trees with some program to stop the insect attack; either actively with insecticides or by thinning. A problem like what is shown in the picture doesn't happen unless there are two factors are involved, an invasive insect (some beetle I'll bet), and weather conditions supportive of the insect's reproduction. Regardless, if the weather (or climate) has tended towards drought conditions over a period of time, that makes for a good forest fire candidate.

The earth absorbs sunlight, warms then reradiates heat (infrared or longwave radiation). The outgoing longwave radiation is absorbed by greenhouse gases in the atmosphere. This heats the atmosphere which in turn re-radiates longwave radiation in all directions.
and a small portion comes back to reheat the surface. As @Deep says, "underlying Physics".

How much energy in in the 15um CO2 notch at 300K? I have performed the calculations and it is not much energy to begin with and even if ALL is absorbed, it is still not very significant.

The absorptivity of CO2 is not so limited as you make it out to be.

More importantly, it peaks very close to the peak of Earth's outgoing thermal radiation, where the absorptivity of H2O is much lower by comparison.

lamda(max)*T = 2898(um * K)
2898/15um = 193K = -80 C.
15 um is the only CO2 peak anywhere near the range of terestrial temps, and the 15um is at -80C.
The peak at 300K is 9.66 um.
Between 9.9 and 14um there is a large atm window to space.
Put that curve on a linear wavelength scale and look a bit more closely at the transmittance.

None of which negates the fact that absorptivity of CO2 peaks very close to the peak of Earth's outgoing thermal radiation, where the absorptivity of H2O is much lower by comparison.

The graph cited by you is of atmospheric transmittance, which is of no material relevance to either the absorptivity of CO2 or H20 or to Earth's radiation spectra

And, you continue to ignore the fact that H2O content is quite stable, whereas that of CO2 continues to rise sharply.

the fact that absorptivity of CO2 peaks very close to the peak of Earth's outgoing thermal radiation,


How much energy absorbed in the 15um band? Not much. A BB at -80C peaks at 15 um.
A BB at 300K peaks at 9.9 um. The earth is treated as a BB at ~15C (287K) with peak ~10um. So there is a LARGE IR window AT typical earth temperatures to radiate energy into space. Which is why dry deserts have daily 20C temp swings from high to low. But if a few clouds roll in at night, that heat is blocked. Tropical daily swings are just a few degs C due to H2O.

How much energy absorbed in the 15um band? Not much. A BB at -80C peaks at 15 um.
A BB at 300K peaks at 9.9 um. The earth is treated as a BB at ~15C (287K) with peak ~10um. So there is a LARGE IR window AT typical earth temperatures to radiate energy into space. Which is why dry deserts have daily 20C temp swings from high to low. But if a few clouds roll in at night, that heat is blocked. Tropical daily swings are just a few degs C due to H2O.

Immaterial, for reasons already stated and more..

It's immaterial how much energy is absorbed by water vapor, the MOST significant greenhouse gas according to NASA?

With respect to the role of CO2 and other gases, YES, it's IMMATERIAL.

But, that's only one of several reasons why your blathering is of no material relevance. And, no, I am not going to repeat any of those reasons, as you've done nothing in this and other threads but continue to evade them.
