Economic analysis of the greenhouse effect: optimal abatement level and strategies for mitigation
The economic analysis of global warming involves identifying and quantifying in economic terms the impacts of global warming and the abatement costs of greenhouse gas emissions. At the global level, countries will act strategically depending on their perceived costs and impacts. This is simulated through a global model of costs and damage of global warming. At the local level, the impacts of ...

Motor transport, greenhouse gases and economic instruments
Motorised transport is the generator of several forms of negative externality including the uncompensated emissions of greenhouse (global warming) gases. This paper looks at some of the underlying economic issues pertaining to policy-making designed to limit the extent of these externalities. It sets out the basic nature of the problem and outlines our knowledge of the link between the physical ...

Global Warming Causing Dwindling Food Supplies
The growth of plants but in excessive amounts they end up bringing destruction. Man-made warming will actually cause a reduction in the amount of food produced compared to if there was no global warming. The last time a similar report was given it said that it was too soon to begin speculating on what effect global warming would have on food production. That was in 2007 but since then more ...

Historical evidence for climate driven migrations in Portuguese fishing community
A multidisciplinary, multilevel methodology that cross-examines existing historical information from past climate (1st half of 20th century), with geographic information and other historical sources available about population movements (demographic census) is proposed, allowing to map climate variability in the same period and its relationship with migration in Portuguese territory. Results are ...

Global warming to result in widespread crop loss to insects
Rice, corn and wheat loss rates could rise by up to 25% with every 1˚C increase to global temperatures as insects start to eat and breed more, new research has found. Led by researchers at Washington University, the study forecasts global warming of 2˚C to push the losses of these three crops up to approximately 213 million tons every year. This could have severe implications ...

Life cycle analysis of wheat and barley crops for bioethanol production in Spain
A Life Cycle Assessment (LCA) of the agricultural production of wheat and barley grain to be used as a raw material for bioethanol production in Spain is performed. The objective of the work presented is to compare the environmental impact of the production of these two alternative raw materials for the production of bioethanol. This study is carried out in the frame of a higher scope study, a ...

Statistical evaluation of the early-stage development of Jatropha energy plantations in Northeastern Mexico
A systematic evaluation of agricultural factors affecting the adaptation of the tropical oil plant Jatropha curcas L. to the semi-arid subtropical climate in Northeastern Mexico has been conducted. The factors studied include plant density and topology, as well as fungi and virus abundances. A multiple regression analysis shows that total fruit production can be well predicted by the area per ...

Spatio-temporal variability of temperature and potential evapotranspiration over India
Worldwide, major changes in the climate are expected due to global warming, which leads to temperature variations. To assess the climate change impact on the hydrological cycle, a spatio-temporal change detection study of potential evapotranspiration (PET) along with maximum and minimum temperatures (Tmax and Tmin) over India have been performed for the second half of the 20th century ...

Efficiency of carbon sequestration by added reactive nitrogen in ocean fertilisation
Addition of limiting nutrients to the surface waters of the deep ocean will lead to increased photosynthesis and associated biological productivity. Some of carbon taken up by phytoplankton will sink to the deep ocean, providing sequestration of carbon in the deep ocean. This paper considers nitrogen as the added nutrient and determines the losses in this sequestration process, taking into ...

Climate, vulnerability and farming: a preliminary study among Australian food growers
The present study examines climate change, vulnerability to climate, and other environmental challenges from the perspective of 80 horticulture operators from different Australian states. Vulnerability in the form of storms and droughts are respondents’ main environmental concerns; in some cases, the impact of wildlife displacement is affecting their production outputs. In addition, substantial ...

Fluorinated greenhouse gases in 2017
Data reported by companies on the production, import, export and destruction of fluorinated greenhouse gases in the European Union, 2007-2016. Executive summary The 2017 edition of the European Environment Agency (EEA) report on fluorinated greenhouse gases (F-gases) confirms the good progress achieved in 2016 by the European Union (EU) in phasing down the use of hydrofluorocarbons (HFCs), ...

Sensitivity analysis of the CERES-wheat model for variations in CO2 and meteorological factors in Northwest Turkey
Plant growth is very sensitive to variations in atmospheric factors. Possible effects of climate change on plant growth can be estimated and evaluated using the crop growth simulation models. In this study, the CERES (Crop Environment Resource Synthesis)-wheat model was applied to two consequent growing seasons (1997–1998 and 1998–1999) in order to determine the model sensitivity on the changes ...

Greenhouse impact of fossil, forest residues and jatropha diesel: a static and dynamic assessment
Biofuels have been recognised as one option for mitigating climate change. However, in order to show the sustainability of biomass-based fuels, an assessment of the savings in Greenhouse Gas (GHG) emissions compared to fossil fuels needs to be clearly shown. There are two ways to measure the greenhouse impact of an activity. It can be done statically or dynamically, by using Global Warming ...

Effect of the solid content on biogas production from Jatropha curcas seed cake
Anaerobic conversion of Jatropha curcas seed cake was studied in a fivelitre working volume batch reactor at 30°C. Over a 60day operating period, a slurry of seed cake in water at a 1 : 20 seed caketowater ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The ...

Re-coupling the carbon and water cycles by Natural Sequence Farming
The techniques of Natural Sequence Farming (NSF) were developed during hands-on management of degraded farmland in the Upper Hunter Valley region of Australia. Early settlement of the continent by people with European cultural assumptions disrupted established interactions of water, soil, and plants resulting in lost fertility. Moreover, agricultural practices such as clearing, burning, ...

Interactions between water temperature and contaminant toxicity to freshwater fish
Warming of freshwaters as a result of climate change is expected to have complex interactions with the toxicity of contaminants to aquatic organisms. The present study evaluated the effects of temperature on the acute toxicity of endosulfan, chlorpyrifos, and phenol to 3 warm water species of fish—silver perch, rainbowfish, and western carp gudgeon—and 1 cold water species, rainbow trout. ...

Getting kids to eat green
Kids love food, but it's not always the tasty treats that are good for them or the earth. Fatty, sugary, salty and processed foods generally have more of an environmental impact than eats of the fresh, locally produced variety. It is therefore important to teach them what is healthy to eat, and how and where their food comes from. This will help them to understand the impact of the food they eat, ...

Habitat-specific responses in the flowering phenology and seed set of alpine plants to climate variation: implications for global-change impacts
The timing of the snowmelt is a crucial factor in determining the phenological schedule of alpine plants. A long-term monitoring of snowmelt regimes in a Japanese alpine area revealed that the onset of the snowmelt season has been accelerated during the last 17 years in early snowmelt sites but that such a trend has not been detected in late snowmelt sites. This indicates that the global warming ...
