Inside Global Warming

Over the last 15 years, much attention has been given to global warming, and whether the increase in the Earth\u27s temperature in recent decades threatens the survival of life on Earth. Release of the films The Day After Tomorrow (2004), where North America is rapidly plunged into a new ice age, and An Inconvenient Truth (2006), where Al Gore focuses on the future impacts of global warming, has raised much public and media attention on the subject. As such, it\u27s important that science teachers understand the basics behind the scientific phenomenon, the controversy surrounding the topic, and how to discuss and explore global warming with their students

An Overview Study on Awareness of Global Warming Among the Graduate Teacher Trainees

Nowadays global warming is considered as a burning problem and it is being a challenge to the entire world and its scientific society. Global warming is a worldwide environmental problem by which there is an abnormal increase to the level of temperature, particularly in a natural environment. Global warming is not only affecting the nature, but it affects the life and homes of millions of people. The changes of global warming is visible from the highest mountains to deep in the oceans and it extinguished different parts of the earth and it's also creates rich bio-diversity. To identify the level of awareness global warming and to enhance the same among future secondary school teachers, the Authors decided to conduct the present research study of awareness on global warming among graduate Teacher trainees of college of education. Further, the study may also help the student teachers of secondary schools to create awareness on global warming among students studying in secondary schools in future. Keywords: global warming, climatic Change, green house effect, environmental refugees, and 3R

Investigating the importance of methane for future climate change: wetland methane emissions, the permafrost carbon feedback, and methane mitigation

Methane (CH4) is a major greenhouse gas (GHG), second only to carbon dioxide (CO2) in the contribution to historical climate forcing. Yet, the level of understanding of how CH4 will influence the future climate remains low because CH4 processes are generally not represented in Earth system models used for future climate projections. The objective of this thesis is to investigate the importance of CH4 for future climate change with a focus on CH4 mitigation as well as wetland CH4 emissions from thawing permafrost soils, and their respective impact on global warming. The thesis includes a description of a new model for wetland CH4 emissions implemented in an Earth system model of intermediate complexity (EMIC) and applications of the EMIC (including a simplified representation of the CH4 cycle) to: (i) investigate the importance of CH4 mitigation to comply with stringent global warming limits, and (ii) project the additional warming due to wetland CH4 emissions from previously frozen carbon following gradual permafrost thaw over the next three centuries. Salient results of this thesis are: (i) immediate cuts in anthropogenic CH4 emissions, alongside CO2 mitigation, are needed to increase the likelihood of limiting global warming to 2°C above pre-industrial levels; (ii) the warming due to wetland CH4 emissions from thawing permafrost soils is projected to be small (<0.05°C) throughout the 21st century independent of the future anthropogenic emission scenario, (iii) the warming due to such permafrost CH4 emissions has the potential to increase substantially beyond the 21st century, reaching 0.09 (0.01-0.24) °C in the year 2300 under a scenario of high anthropogenic emissions. Overall, by incorporating a simplified representation of the CH4 cycle in Earth system model simulations, this thesis suggests that (i) delaying CH4 mitigation to after the year 2040 will constitute a challenge for limiting global warming to 2°C even if anthropogenic CO2 emissions were reduced aggressively, (ii) reducing anthropogenic GHG emissions will allow to limit the warming due to wetland CH4 emissions from thawing permafrost soils to well below 0.1°C over the next three centuries

Is Global Warming likely to cause an increased incidence of Malaria?

The rise in the average temperature of earth has been described as global warming which is mainly attributed to the increasing phenomenon of the greenhouse effect. It is believed that global warming can have several harmful effects on human health, both directly and indirectly. Since malaria is greatly influenced by climatic conditions because of its direct relationship with the mosquito population, it is widely assumed that its incidence is likely to increase in a future warmer world

Awareness And Perception of Global Warming Among Undergraduate Medical Students in A Nigerian University.

BACKGROUND: Increase in the emission of green house gases and the attendant climatic changes have led to the phenomenon of global warming with all its catastrophic consequences.OBJECTIVE: To assess knowledge and perception of the concept of global warming among undergraduate medical studentsMETHODOLOGY: A cross sectional descriptive study was carried out among 380 undergraduate medical students who were selected by a systematic sampling method. A semi-structured, self-administered questionnaire was used to collect data on their demographic attributes and their knowledge and perception of global warming after a verbal informed consent was obtained from them.RESULTS: All the respondents had heard of global warming with 7.1% having excellent knowledge, 45% good knowledge, 43.7% fair knowledge and 13.2% poor knowledge of global warming. Most (82.1%) had the misconception that ozone layer depletion was responsible for global warming. A majority (94%) believed the earth was actually warming up, with 73% believed they contributed to global warming. Only 16.1% perceived that global warming will affect the future generations. Though 198(52%) felt they were already taking actions to conserve energy, only 34(9.0%) would rather use public transport than buy a car in order to conserve energy.CONCLUSION The knowledge and perception of the concept of global warming among the respondents were good. However, most confused the concept of global warming with ozone layer depletion. Continuous education on issues of global warming especially the misconceived aspects is advocated

Threat by marine heatwaves to adaptive large marine ecosystems in an eddy-resolving model.

Marine heatwaves (MHWs), episodic periods of abnormally high sea surface temperature (SST), severely affect marine ecosystems. Large Marine Ecosystems (LMEs) cover ~22% of the global ocean but account for 95% of global fisheries catches. Yet how climate change affects MHWs over LMEs remains unknown, because such LMEs are confined to the coast where low-resolution climate models are known to have biases. Here, using a high-resolution Earth system model and applying a "future threshold" that considers MHWs as anomalous warming above the long-term mean warming of SSTs, we find that future intensity and annual days of MHWs over majority of the LMEs remain higher than in the present-day climate. Better resolution of ocean mesoscale eddies enables simulation of more realistic MHWs than low-resolution models. These increases in MHWs under global warming poses a serious threat to LMEs, even if resident organisms could adapt fully to the long-term mean warming

Education Software Design of Faculty Room for Energy Efficiency

Nowadays, Global Warming has become a new issue whom impact can be very devastating and can threat the earth and human existence in the future. Since the impact can be very dangerous, many efforts have been done and many ideas have been proposed to prevent and reduce the effect of Global Warming. One of them is to introduce the importance of energy saving. This paper reports on the process of design and development of the prototype of an alternative solution which implement serious game to introduce to the user the importance of buying appliances which can consume energy efficientl

Arctic system on trajectory to new state

The Arctic system is moving toward a new state that falls outside the envelope of glacial-interglacial fluctuations that prevailed during recent Earth history. This future Arctic is likely to have dramatically less permanent ice than exists at present. At the present rate of change, a summer ice-free Arctic Ocean within a century is a real possibility, a state not witnessed for at least a million years. The change appears to be driven largely by feedback-enhanced global climate warming, and there seem to be few, if any processes or feedbacks within the Arctic system that are capable of altering the trajectory toward this “super interglacial” state
