A selection of new climate related research articles is shown below.

Climate change

1. Continuously Amplified Warming in the Alaskan Arctic: Implications for Estimating Global Warming Hiatus

"Focusing on the "hiatus" period 1998-2012 as identified by the Intergovernmental Panel on Climate Change (IPCC) report, the SAT has increased at 0.45 °C/decade, which captures more than 90% of the regional trend for 1951-2012. We suggest that sparse in-situ measurements are responsible for underestimation of the SAT change in the gridded datasets."

2. Extreme warming in the Kara Sea and Barents Sea during the winter period 2000 to 2016

"The maximum warming occurs north of Novaya Zemlya in the Kara Sea and Barents Sea between March 2003-2012 and is responsible for up to 20°C increase. Land-based observations confirm the increase but do not cover the maximum regions that are located over the ocean and sea-ice."

3. Tropical semi-arid regions expanding over temperate latitudes under climate change

"We show that a global expansion of this climatic domain has already started according to climate observations in the twentieth century (about + 13% of surface increase, i.e. from 6 to 7% of the global land surface). Models project that this expansion will continue throughout the twenty-first century, whatever the scenario..."

4. Representation of mid-latitude North American coastal storm activity by six global reanalyses

"All reanalyses are found to successfully represent most aspects of mid-latitude North American coastal strong storm activity, annually and seasonally, along both coasts. Nevertheless, ERA-Interim, MERRA, and CFSR provide the better representations of mid-latitude North American coastal strong storm activity, with ERA-Interim performing best overall."

5. Is Nitrogen the Next Carbon?

"The increased use of nitrogen has been critical for increased crop yields and protein production needed to keep pace with the growing world population. However, similar to carbon, the release of fixed nitrogen into the natural environment is linked to adverse consequences at local, regional, and global scales. Anthropogenic contributions of fixed nitrogen continue to grow relative to the natural budget, with uncertain consequences."

6. Annual and seasonal tornado activity in the United States and the global wind oscillation

"Combined, these analyses suggest that seasons with more low atmospheric angular momentum days, or phase 2, 3, and 4 days, tend to have greater tornado activity than those with fewer days, and that this relationship is most evident in winter and spring."

7. Assessing climate change impacts on extreme weather events: the case for an alternative (Bayesian) approach

"Using a simple conceptual model for the occurrence of extreme weather events, we show that if the objective is to minimize forecast error, an alternative approach wherein likelihoods of impact are continually updated as data become available is preferable. Using a simple “proof-of-concept,” we show that such an approach will, under rather general assumptions, yield more accurate forecasts."

22. Seasonal temperature is associated with Parkinson’s disease prescriptions: an ecological study

"The prescribed LED was 4.2% greater in January and 4.5% lower in July. Statistical analysis showed that temperature was associated with the prescription of Parkinson medications. Our results suggest seasonality exists in Parkinson’s disease symptoms and this may be related to temperature."

23. The effects of hot nights on mortality in Barcelona, Spain

"The estimated associations for both exposure variables and mortality shows a relationship with high and medium values that persist significantly up to a lag of 1–2 days. In mortality due to natural causes, an increase of 1.1% per 10% (CI95% 0.6–1.5) for hot night hours and 5.8% per each 10° (CI95% 3.5–8.2%) for hot night degrees is observed."

24. Leap-frog in slow-motion: divergent responses of tree species and life stages to climatic warming in Great Basin sub-alpine forests

"Bristlecone pine juveniles establishing above treeline share some environmental associations with bristlecone adults. Limber pine above-treeline juveniles, in contrast, are prevalent across environmental conditions and share few environmental associations with limber pine adults. Strikingly, limber pine is establishing above treeline throughout the region without regard to site characteristic such as soil type, slope, aspect, or soil texture. Though limber pine is often rare at treeline where it coexists with bristlecone pine, limber pine juveniles dominate above treeline even on calcareous soils that are core bristlecone pine habitat. Limber pine is successfully “leap-frogging” over bristlecone pine, probably because of its strong dispersal advantage and broader tolerances for establishment."

25. Ocean acidification alters zooplankton communities and increases top-down pressure of a cubozoan predator

"Specifically, we show that in the combined presence of OA and a cubozoan predator, populations of the most abundant member of the zooplankton community (calanoid copepods) were reduced 27% more than it would be predicted based on the effects of these stressors in isolation, suggesting that OA increases the susceptibility of plankton to predation. Our results indicate that the ecological consequences of OA may be greater than predicted from single-species experiments, and highlight the need to understand future marine global change from a community perspective."

26. Future reef growth can mitigate physical impacts of sea-level rise on atoll islands

"Comparatively, vertical reef accretion in response to SLR will prevent any significant increase in shoreline wave energy and mitigate wave driven flooding volume by 72%."

41. Does the world have low-carbon bioenergy potential from the dedicated use of land?

ABSTRACT: "While some studies find no room for the dedicated use of land for bioenergy because of growing food needs, other studies estimate large bioenergy potentials, even at levels greater than total existing human plant harvest. Analyzing this second category of studies, we find they have in various ways counted the carbon benefits of using land for biofuels but ignored the costs. Basic carbon opportunity cost calculations per hectare explain why alternative uses of any available land are likely to do more to hold down climate change. Because we find that solar power can provide at least 100 times more useable energy per hectare on three quarters of the world's land, any “surplus” land could also provide the same energy and mitigate climate ~ 100 times more if 1% were devoted to solar and the rest to carbon storage. Review of large bioenergy potential estimates from recent IAMs shows that they depend on many contingencies for carbon benefits, can impose many biodiversity and food costs, and are more predictions of what bioenergy might be in idealized than plausible, future scenarios. At least at this time, policy should not support bioenergy from energy crops and other dedicated uses of land."

42. Who Wins from Emissions Trading? Evidence from California

"Importantly, conditional on race and ethnicity, we find that higher income areas receive larger reductions in pollution under cap-and-trade. Furthermore, conditional on income (or poverty rates), we find that Blacks benefit while Hispanics lose relative to whites under RECLAIM."

43. Climate change and the re-evaluation of cost-benefit analysis

"In this essay, I discuss the shortcomings of CBA framed by its historical development and argue that its relatively recent application to climate change has contributed to growth in the literature re-evaluating its normative foundations."

48. On the impacts of computing daily temperatures as the average of the daily minimum and maximum temperatures

"Our results show that the calculation of daily temperature based on the average of minimum and maximum daily readings leads to an overestimation of the daily values of ~ 10+ % when focusing on extremes and values above (below) high (low) thresholds. Moreover, the effects of the data processing method on trend estimation are generally small, even though the use of the daily minimum and maximum readings reduces the power of trend detection (~ 5–10% fewer trends detected in comparison with the reference data)."

  1. From #3 above: "...Models project that this expansion will continue throughout the twenty-first century, whatever the scenario..."

    Well...that sounds kinda...bad...

  2. Is Nitrogen the new Carbon.  Probably, but it doesn't have to be so.  Read David R Mongomery's book Growing a Revolution.  Not only could we stop this trend but the farmers could be the hero's of the age while actually increasing their profits.  What is needed is demonstration farms spread far and wide.  Farmers are incredible conservative (dad did it and so did grandad) so only an example is likely to sway them.  Research at an agricultural institution won't hack it.  What dean of agriculture will allow research on his patch which will cause his main contributors to stop their funding . (fertilizer manufacturers for instance)

  3. #5. Is Nitrogen the Next Carbon?

    One of the consequences of human added nitrate in soils is that nitrogen fixing plants cannot thrive in this enriched environment. This is especially true of leguminous plants.   With a long time interest in photographing bees, especially bumble bees, I have noted a decided decline in the numbers of these animals in my local environment, Southern Hampshire, England this century.  Bees of all species prefer leguminous plants e.g. clover for the pollen from these is richer in protein, much richer than many plants chosen for flower beds and borders.

    Scientist and author Dave Goulson  has explored this intensively by purchasing a run down farm in France and stripping off the over fertilised soil and then working several crops over years to further deplete the nitrates restoring clover and other similar species.  This, and much more is described in his book 'A Sting in the Tail' of which more can be found here:
