A selection of new climate related research articles is shown below...
1. Modelling past, present and future peatland carbon accumulation across the pan-Arctic region
"We found that peatlands in Scandinavia, Europe, Russia and central and eastern Canada will become C sources, while Siberia, far eastern Russia, Alaska and western and northern Canada will increase their sink capacity by the end of the 21st century."
2. Annual and seasonal tornado trends in the contiguous United States and its regions
"The annual analyses indicate that the number of tornadoes per year declined in the West, North Great Plains, South Great Plains, and Midwest regions, but increased in the Southeast." ... "Seasonal analyses suggest that the proportion of tornadoes occurring in the contiguous United States in summer is decreasing whereas the proportion occurring in fall is increasing. This is especially apparent in the Southeast."
3. Beyond equilibrium climate sensitivity
"Newer metrics relating global warming directly to the total emitted CO2 show that in order to keep warming to within 2 °C, future CO2 emissions have to remain strongly limited, irrespective of climate sensitivity being at the high or low end."
4. Dynamic response of an Arctic epishelf lake to seasonal and long-term forcing: implications for ice shelf thickness
"We show that the Milne Ice Shelf, Ellesmere Island, was stable before 2004, after which time the ice shelf thinned rapidly."
5. Future changes in tropical cyclone activity in high-resolution large-ensemble simulations
"The global number of TCs decreases by 33% in the future projection. Although geographical TC occurrences decrease generally, they increase in the central and eastern parts of the extratropical North Pacific. Meanwhile, very intense (category 4 and 5) TC occurrences increase over a broader area including the south of Japan and south of Madagascar. The global number of category 4 and 5 TCs significantly decreases, contrary to the increase seen in several previous studies. Lifetime maximum surface wind speeds and precipitation rate are amplified globally. "
6. Response of Tropical Cyclone Activity and Structure to Global Warming in a High-Resolution Global Nonhydrostatic Model
"The model projected that the global frequency of TCs is reduced by 22.7%, the ratio of intense TCs is increased by 6.6%, and the precipitation rate within 100 km of the TC center increased by 11.8% under warmer climate conditions. These tendencies are consistent with previous studies using hydrostatic global model with cumulus parameterization." ... "Hence, this study shows that the horizontal scale of TCs defined by the radius of 12 m s-1 surface wind is projected to increase compared with the same intensity categories for SLP less than 980 hPa."
7. Air-Sea CO2 Exchange in the Ross Sea, Antarctica
"We find that the Ross Sea is a lesser atmospheric CO2 sink (-7.5±0.5 Tg C yr−1, -1.3±0.1 mol C m−2 yr−1) than previously reported (-13 Tg C yr−1, -1.7 to -4.2 mol C m−2 yr−1)."

36. Glacier shrinkage driving global changes in downstream systems
"Here, we synthesize current evidence of how glacier shrinkage will alter hydrological regimes, sediment transport, and biogeochemical and contaminant fluxes from rivers to oceans. This will profoundly influence the natural environment, including many facets of biodiversity, and the ecosystem services that glacier-fed rivers provide to humans, particularly provision of water for agriculture, hydropower, and consumption."
37. Analysis of climate signals in the crop yield record of Sub-Saharan Africa
"We found that improved agricultural technology and country fixed effects are three times more important than climate variables for explaining changes in crop yields in SSA. We also found that increasing temperatures reduced yields for all three crops in the temperature range observed in SSA, while precipitation increased yields up to a level roughly matching crop evapotranspiration."
38. Behavioral responses to annual temperature variation alter the dominant energy pathway, growth, and condition of a cold-water predator
"In cooler years, fish ate more large prey from shallow nearshore regions, resulting in higher growth and condition than in warmer years, when fish ate more small prey from deep offshore regions. This suggests that the impacts of warming on aquatic ecosystems can scale from the individual to the food web level."
39. Carbon dioxide fertilization offsets negative impacts of climate change on Arabica coffee yield in Brazil
"The model projects that yield losses due to high air temperatures and water deficit will increase, while losses due to frost will decrease. Nevertheless, extra losses are offset by the CO2 fertilization effect, resulting in a small net increase of the average Brazilian Arabica coffee yield of 0.8% to 1.48 t ha−1 in 2040–2070, assuming growing locations and irrigation remain unchanged. Simulations further indicate that future yields can reach up to 1.81 t ha−1 provided that irrigation use is expanded."

55. Consideration of carbon dioxide release during shell production in LCA of bivalves
"When we recalculated the total kg CO2 released in past studies including CO2 release from shell production, the additional CO2 release increased the total global warming impact category (CO2equivalents) in cradle-to-gate studies by approximately 250% of the original reported value."
56. Estimation and uncertainty of recent carbon accumulation and vertical accretion in drained and undrained forested peatlands of the southeastern USA
"In the drained (GDS) vs. intact (AR) CDR sites, carbon accumulation rates were similar with 137Cs (87GDS vs. 92AR g C m-2 yr-1) and somewhat less at the GDS than AR as determined with 210Pb (111GDS vs. 159AR g C m-2 yr-1)."
57. Was it worthwhile? Where have the benefits of rooftop solar photovoltaic generation exceeded the cost?
"We find that, after accounting for federal subsidies and local rebates and assuming a discount rate of 7%, the private benefits of new installations will exceed private costs only in seven of the 19 states for which we have data and only if customers can sell excess power to the electric grid at the retail price. These states are characterized by abundant sunshine (California, Texas and Nevada) or by high electricity prices (New York)."

"Thanks to the 1987 Montreal Protocol and its amendments, ozone-depleting chlorine (and bromine) in the stratosphere has declined slowly since the late 1990s. Improved and extended long-term ozone profile observations from satellites and ground-based stations confirm that ozone is responding as expected and has increased by about 2 % per decade since 2000 in the upper stratosphere, around 40 km altitude. At lower altitudes, however, ozone has not changed significantly since 2000."
66. Biotic impacts of temperature before, during, and after the end-Permian extinction: A multi-metric and multi-scale approach to modeling extinction and recovery dynamics
"These results suggest that global ocean temperatures best predict patterns of extinction and recovery across several ecological metrics, and that thermal episodes during the initial extinction event and subsequently in the Early Triassic recovery period significantly suppressed benthic marine community health."
