Evaluation of terrestrial carbon cycle models for their response to climate variability and to CO2 trends. Reduced streamflow in water-stressed climates consistent with CO2 effects on vegetation. Climate change, deforestation, and the fate of the Amazon. A two-fold increase of carbon cycle sensitivity to tropical temperature variations. Detection and attribution of vegetation greening trend in China over the last 30 years. Global latitudinal-asymmetric vegetation growth trends and their driving mechanisms: 1982–2009. Analysis of trends in fused AVHRR and MODIS NDVI data for 1982–2006: indication for a CO2 fertilization effect in global vegetation. Temperature and vegetation seasonality diminishment over northern lands. A large and persistent carbon sink in the world’s forests. Increased plant growth in the northern high latitudes from 1981 to 1991. in Climate Change 2013: The Physical Science Basis (eds Stocker, T. The challenge to keep global warming below 2°. The regional effects of unexplained factors suggest that the next generation of ecosystem models will need to explore the impacts of forest demography, differences in regional management intensities for cropland and pastures, and other emerging productivity constraints such as phosphorus availability. LCC contributed most to the regional greening observed in southeast China and the eastern United States. CO 2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau. Factorial simulations with multiple global ecosystem models suggest that CO 2 fertilization effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate change (8%) and land cover change (LCC) (4%). We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning).

Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key drivers of LAI trends during 1982–2009. Yet how global vegetation is responding to the changing environment is not well established. Global environmental change is rapidly altering the dynamics of terrestrial vegetation, with consequences for the functioning of the Earth system and provision of ecosystem services 1, 2. Nature Climate Change volume 6, pages 791–795 ( 2016) Cite this article is a young family business founded in 2014 by father and son Klaus and Jakov Schmied, designing and producing high-tech components for the electrics and automotive industries. The guards have been designed against 250 shin scans to match as closely as possible to eliminate any pressure points.īernstein Innovation Ltd. Zweikampf shin guards weigh as little as 75 grams, are 7mm thick and styled in the sleek-looking black and yellow colours.
Jakob Schmied, founder of Bernstein Innovation Ltd. The second and third layers closest to the shin are crafted from XRD multifunctional material with the middle layer forming the protective hard layer and the 'Inlay' providing utmost comfort. A 3D-printed shell is inspired by the model of the Samurai. Three high-tech layers comprise the shin guards providing comfort and variation in the size and degree of hardness. The idea for the 'Zweikampf' was conceived two years ago and is now able to be pre-ordered exclusively on kickstarter for one month starting 18 April 2016. A world’s first in serially-produced 3D-printed shin guardsīernstein Innovation has created the first serially-produced 3D-printed football shin guards in the world.
