- ... The Fifth National Communication Under the Framework Convention on Climate Change covered the policies and activities in Estonia of the period 2006–2009. Climate change and air pollution cause significant damage, especially to various materials. Worldwide, 387 objects belong to the United Nations Educational, Scientific and Cultural Organization (UNESCO) World heritage list, including the Old Town ...

- Abstract:
- ... Research in phenology change has been one heated topic of current ecological and climate change study. In this study, we use satellite derived NDVI (Normalized Difference Vegetation Index) data to explore the spatio-temporal changes in the timing of spring vegetation green-up in the Qinghai-Xizang (Tibetan) Plateau from 1982 to 2006 and to characterize their relationship with elevation and tempera ...

- Abstract:
- ... In the recent debate on climate change economics triggered by the Stern Review and his opponents, fundamental methodological issues emerge. It becomes obvious that different choices for some variables in the models applied lead to vastly different conclusions. Specifically, the choice of the pure time discount rate δ decides on whether immediate strong action (in the Stern Review) or a more modera ...

- Abstract:
- ... The threat of climate change is now recognized as an imminent issue at the forefront of the forest sector. Incorporating adaptation to climate change into forest management will be vital in the continual and sustainable provision of forest ecosystem services. The objective of this study is to investigate climate change adaptation in forest management using the landscape disturbance model LANDIS-II ...

- Abstract:

Using thermal infrared satellite data, a recent study found that a global set of inland water bodies showed significant warming in seasonal nighttime Lake Surface Water Temperatures (LSWTs) between 1985 and 2009. Split-window land surface temperature (LST) retrievals are typi ...

- Abstract:
- ... Across the Pacific Northwest, the climate between 1950 and 1975 was exceptionally cool and wet compared with more recent conditions (1995–2005). We reasoned that the changes in climate could result in expanded outbreaks of insects, diseases, and fire. To test this premise, we first modeled monthly variation in photosynthesis and growth of the most widely distributed species, Douglas-fir (Pseudotsu ...

- Abstract:
- ... Soils are the biggest carbon store in the world (1500Gt, e.g. 1.5×10²¹g). The European Commission indicates the accounting of soil organic carbon (SOC) variations in space and time as the first step in the strategy for soil protection. It is indeed necessary in evaluating the risk of soil organic matter decline and soil biodiversity decline, and when evaluating the role played by soils in global C ...

- Abstract:

Climate change is set to increase the variability and uncertainty of inter-annual rainfall. Farmers who depend on rainfed maize production for their livelihoods would therefore benefit from improved climate based forecasting of production likelihood. In this study we developed a simple ma ...

In this study we conducted correlation and regression analyses of climate records of seventy-two meteorological stations and records of corn yield over the period 1965â2008 in Northeast China. It was found that over these forty-four years, the di ...

Previous studies suggest 3 kelvin (K) as the best estimate, 2 to 4.5 K as the 66% probability range, and nonzero probabilities for much higher values, the latter implying a small chance of high-impact climate ...

Investigation was made on the hydrological extremes of the upper Blue Nile basin in Ethiopia through the use of high and low flow probability distributions and flow-duration-frequency (QDF) relations. The dependence of QDF predictions on the period used for the analysis was investigated considering the possibility that short historical records might cover periods with a cluster of wet/dry years or ...

Earth’s modern climate, characterized by polar ice sheets and large equator-to-pole temperature gradients, is rooted in environmental changes that promoted Antarctic glaciation approximately 33.7 million years ago. Onset of Antarctic glaciation reflects a critical tipping point for Earth’s climate and provides a framework for investigating the role of atmospheric carbon dioxide (CO2) during major ...

Both conferences of the parties (COP) at Copenhagen (termed “Hopenhagen”) and Cancun were a disappointment as they failed to deliver a legally binding agreement that will ensure global temperature rise remains well below agreed on targets. Achieving this agreement would be the ultimate expression of climate justice. Arriving at this agreement may be facilitated by exploring a deeper definition of ...

To understand its effects on Australia's avifauna, we need to evaluate the effects of annual climatic variability and geographical climate gradients.

- Abstract:

To date, these constraints have focused on simplistic factors such as limited resources and lack of information. In this paper we argue that this focus has obscured a wider set of constraints which need to be acknowledged and addressed if adaptation is likely to advance through municipal plan ...

These studies generally make simplistic assumptions about the response of an individual to variations in climate. However, empirical evidence of environmentally induced migration does not support such a structural approach and r ...

This is not always true in large basins, where aggregation and buffering effects have dampen the ability to determine the driving forces of sedimentation. Even though there are significant responses to sedimentation in large river basins, it is difficul ...
