title: NOAA/WDS Paleoclimatology - Gulf of California alkenone and leaf wax isotope data over the last 1300 years

description: The North American Monsoon influences the ecosystems and hydroclimate of the southwestern United States and northwestern Mexico. This is a geographically complex region, including the narrow Gulf of California adjacent to the Sierra Madre Occidental. Alongside this complexity, unreliable gridded data products, a lack of long instrumental observations, and limited high-resolution paleoclimate records from the core monsoon region prevent a complete understanding of the variability and drivers of this system on time scales from decades to millennia. Here we generate new proxy records of warm-season sea-surface temperature (SST, based on alkenone Uk'37) and terrestrial hydroclimate (based on plant wax hydrogen isotopes) from Gulf of California (GoC) sediment cores spanning 744 to 1980 CE. Although the GoC is an important source of monsoon moisture, we find no one-to-one correlation between SST and our hydroclimate reconstruction over the full time period. Spectral analyses revealed a prominent multicentennial oscillation in the SST reconstruction, as well as multidecadal modes in both records. There is a small cooling trend over the full SST reconstruction, but no clearly delineated Medieval Climate Anomaly or Little Ice Age. Colder periods in our SST reconstruction appear to be associated with periods of increased volcanism, but there is no definitive solar signal. Multidecadal climate variability in this region is likely linked to broader patterns of unforced variability in the Pacific Ocean-atmosphere system, but any coupling between monsoon strength and Gulf of California SST over the Common Era appears to be complex.

title: NOAA/WDS Paleoclimatology - Schneider - Berlin Grünanlage Britz-Süd den07 - TICO - ITRDB DEU310

description: Using dendroclimatological techniques this study investigates whether inner city tree-ring width (TRW) chronologies from eight tree species (ash, beech, fir, larch, lime, sessile and pedunculate oak, and pine) are suitable to examine the urban heat island of Berlin, Germany. Climate-growth relationships were analyzed for 18 sites along a gradient of increasing urbanization covering Berlin and surrounding rural areas. As a proxy for defining urban heat island intensities at each site, we applied urbanization parameters such as building fraction, impervious surfaces, and green areas. The response of TRW to monthly and seasonal air temperature, precipitation, aridity, and daily air-temperature ranges were used to identify climate-growth relationships. Trees from urban sites were found to be more sensitive to climate compared to trees in the surrounding hinterland. Ring width of the deciduous species, especially ash, beech, and oak, showed a high sensitivity to summer heat and drought at urban locations (summer signal), whereas conifer species were found suitable for the analysis of the urban heat island in late winter and early spring (winter signal). The summer and winter signals were strongest in tree-ring chronologies when the urban heat island intensities were based on an area of about 200 m to 3000 m centered over the tree locations, and thus reflect the urban climate at the scale of city quarters. For the summer signal, the sensitivity of deciduous tree species to climate increased with urbanity. These results indicate that urban trees can be used for climate response analyses and open new pathways to trace the evolution of urban climate change and more specifically the urban heat island, both in time and space.

description: Projected warming of global surface air temperatures will further exacerbate droughts, wildfires, and other agents of ecosystem stress. We use latewood blue intensity from high-elevation Picea engelmannii to reconstruct late-summer maximum air temperature for the Greater Yellowstone Ecoregion (GYE) spanning 770-2019 CE. Using a robust regression model (r2=0.60), the 1,250-year reconstruction reveals 2016 as the single-warmest year and the warming trend since ca. 2000 as the most intense. The Medieval Climate Anomaly contained the highest-ranking warm event (1050-1070 CE) and was characterized by substantial multi-decadal variability rather than a period of prolonged, homogeneous warming. We document regional expression of past warm and cool events, such as an anomalously warm period spanning the 15th-16th centuries, and the Maunder and Dalton minima of the Little Ice Age. Summer temperature variability across the GYE shows multi-centennial agreement with trends in solar irradiance, volcanic activity, snowpack, and other regional-to-hemispheric temperature records.

title: NOAA/WDS Paleoclimatology - North fire data from Philbrook Creek Riparian/upland - IMPD USPB_001

description: Fire is an important ecological process in many western U.S. coniferous forests, yet high fuel loads, rural home construction and other factors have encouraged the suppression of most wildfires. Using mechanical thinning and prescribed burning, land managers often try to reduce fuels in strategic areas with the highest fuel loads. Riparian forests, however, are often designated as areas where only limited management action can take place within a fixed-width zone. These highly productive forests have developed heavy fuel loads capable of supporting stand-replacing crown fires that can alter wildlife habitat and ecosystem function, and contribute to stream channel erosion. Objectives of this study were to determine whether adjacent coniferous riparian and upland forests burned historically with different frequencies and seasonalities, and whether these relationships varied by forest, site, and stream characteristics. We measured dendrochronological fire records in adjacent riparian and upland areas across a variety of forest, site and stream conditions at 36 sites in three sampling areas in the northern Sierra Nevada.  Riparian fire return intervals (FRI) ranged from 8.4 to 42.3 years under a liberal filter (mean 16.6), and 10.0 to 86.5 years under a conservative filter (mean 30.0). Upland FRI ranged from 6.1 to 58.0 years under a liberal filter (mean 16.9), and 10.0 to 56.3 years under a conservative filter (mean 27.8). Riparian and upland fire return intervals were significantly different in only one quarter of the sites we sampled. Riparian and upland areas did not burn with different seasonalities, and fire events occurred primarily during the late summer-early fall dormant season in both riparian and upland areas (88% and 79% of scars, respectively). FRI was shorter in forests with a higher proportion (>22.7-37.6%) of fire-tolerant pine(Pinus spp.), sites east of the Sierra crest, lower elevation sites (<1944 m), and riparian zones bordering narrower, more incised streams (width/depth ratio <6.2). Upland areas exhibited a greater degree of fire-climate synchrony than riparian areas. Our study suggests that Sierra Nevada coniferous riparian forests bordering many montane streams might be managed for fuel loads and fire return intervals similar to adjacent upland forests.

title: NOAA/WDS Paleoclimatology - North fire data from Bridgeport - IMPD USBRG001

description: There have been few fire history studies of eastern Sierra Nevada forests in California, USA, where a steep elevation gradient, rain shadow conditions, and forest stand isolation may produce different fire regimes than those found on the range's western slope. We investigated historic fire regimes and potential climate influences on four forest types ranging in elevation from 1700 m to 3200 m on the Sierra Nevada's eastern slope and the White Mountains' western slope. Sample areas (approximately 15 ha to 45 ha) had mean site fire return intervals ranging from 4.8 yr to 16.9 yr across ten Jeffrey pine (Pinus jeffreyi Balf.) sites, and 13.4 yr to 45.7 yr across four high elevation lodgepole (P. contorta Douglas ex Louden), foxtail (P. balfouriana Balf.) and bristlecone (P. longaeva D.K. Bailey) pine sites. At most sites (13 of 14), >50 % of fire events occurred in late or dormant season wood. Twentieth century fire return intervals increased at some sites, while other sites continued to record frequent fire events into the 1950s. Years where two or more sites recorded fire events on two or more trees were correlated with drought conditions forecast by the Palmer Drought Severity Index (PDSI) in our sample locations at and north of Mammoth Lakes. The lower Sierra Nevada crest due west of these locations may connect weather patterns with western slope conditions more than at our southern eastside sample sites, which were not significantly correlated with PDSI. Our results suggest eastern Sierra Nevada Jeffrey pine forests have similar seasonality and fire return intervals as some western slope forests, but site fire history can be influenced by stand isolation, historical use, and local rain shadow conditions.
