Previous reports from laboratory-controlled experiments and models considered that a shorter reproductive period could be the main reason for wheat yield reduction in the warmer world. However, this conclusion needs to be proved carefully by field-scale experiments. In this study, a field-scale continuous open-warming experiment was conducted to quantify the adjustment of winter wheat growth an...
The Arctic sea ice cover is in decline. The areal extent of the ice cover has been decreasing for the past few decades at an accelerating rate. Evidence also points to a decrease in sea ice thickness and a reduction in the amount of thicker perennial sea ice. A general global warming trend has made the ice cover more vulnerable to natural fluctuations in atmospheric and oceanic forcing. The obs...
———————————————————————————————Abstract Given the emphasis of saving the Earth against the effect of global warming, green technology has become mandatory in every aspect of life today. Green computing is the study and practice of using computing resources efficiently so as to reduce CO2 emission. This paper is an attempt to comprehend the awareness of green computing among the students of Univ...
While several thousand square kilometers of land area have been subject to surface mining in the Central Appalachians, no reliable estimate exists for how much coal is produced per unit landscape disturbance. We provide this estimate using regional satellite-derived mine delineations and historical county-level coal production data for the period 1985-2005, and further relate the aerial extent ...
Sensitivity experiments using a coupled model initialized from analysed atmospheric and oceanic observations are used to investigate the potential for interannual-to-decadal predictability. The potential for extending seasonal predictions to longer time scales is explored using the same coupled model configuration and initialization procedure as used for seasonal prediction. It is found that, d...
Prior research has found that affect and affective imagery strongly influence public support for global warming. This article extends this literature by exploring the separate influence of discrete emotions. Utilizing a nationally representative survey in the United States, this study found that discrete emotions were stronger predictors of global warming policy support than cultural worldviews...
waste is a by-product of our daily activities, which poses a serious threat to societies all over the world. in this study, life cycle assessment (lca) methodology was used to determine municipal solid waste (msw) management strategy for minna, niger state, nigeria. three scenarios were modelled as alternatives to the current waste management system in minna. the baseline scenario was the exist...
I treat the dynamics of interorganizational collaboration from a dialogue perspective. This extends the âexploitativeâ and âexplorativeâ approaches that currently define scholarship on interorganizational collaboration. A dialogue perspective is argued to be particularly useful in understanding interorganizational efforts to tackle systemic issues that are technically as well as behavio...
Plant phenological records are crucial for predicting plant responses to global warming. However, many historical records are either short or replete with data gaps, which pose limitations and may lead to erroneous conclusions about the direction and magnitude of change. In addition to uninterrupted monitoring, missing observations may be substituted via modeling, experimentation, or gradient a...
Precipitation over India is driven by the Indian monsoon. Although changes in this atmospheric circulation are caused by the differential seasonal diabatic heating of Asia and the Indo-Pacific Ocean, it is so far unknown how global warming influences the monsoon rainfalls regionally. Herein, we present a Miocene pollen flora as the first direct proxy for monsoon over southern India during the M...
