Analyses of Cassini imaging data with this model reveals that the moons Aegaeon, Methone and Pallene are darker than one would expect given trends previously observed among the nearby mid-sized satellites. On the other hand, the trojan moons Calypso and Helene have substantially brighter surfaces than their co-orbital companions Tethys and Dione. These observations are inconsistent with the moons' surface brightnesses being entirely controlled by the local flux of E-ring par- ticles, and therefore strongly imply that other phenomena are affecting their surface properties. The darkness of Aegaeon, Methone and Pallene is correlated with the fluxes of high-energy protons, implying that high-energy radiation is responsible for darkening these small moons. Meanwhile, Prometheus and Pandora appear to be brightened by their interactions with nearby dusty F ring, implying that enhanced dust fluxes are most likely responsible for Calypso's and Helene's excess brightness. -

The presence of water has long been seen as a key condition for life in planetary environments. The Cassini spacecraft discovered water vapour in the Saturnian system by detecting absorption of UV emission from a background star. Investigating other possible manifestations of water is essential, one of which, provided physical conditions are suitable, is maser emission. -
'Zero Carbon': the Wrong Problem Diagnosis, the Wrong 2050 Metric of Success, for New Zealand and the World
‘Zero Carbon’: The Wrong Problem Diagnosis, The Wrong 2050 Metric of Success, for New Zealand and The World. The government surely must agree?: Climate Change is 'merely' one symptom' of ‘The Real Problem’? ‘The Real Problem’ is that Humanity is living well beyond the bioregenerative capacity of the Planet's Ecosystem. (>70% Beyond!) 1970 was the last time the world was in balance, and ever since then the deficit has been steadily increasing without any sign of abating! (This with all the ‘amazing’ ‘Sustainability’ work going on around the world!) The ‘Issue’ is about ‘real’ 'Sustainable Living' and what ‘that’ really means for ‘The World’, a ‘Nation’, and right down to each, and every individual? I'm sure every New Zealander would agree: 'Sustainable Living', and being a 'Sustainable Nation', means: 'We' as a collective, should all be living within our 'fair share' of less than One Planet's, Ecological Regenerative Biocapacity limits? This surely must be, '‘The Ultimate Goal’' of humanity? It's well accepted that anthropogenic Carbon Emissions are a huge contributor to ‘The Real Problem’, but due to the inter-relationship between the Earth's bioregenerative resources, the solution, and particularly when looking to 2050, requires more than a simple, Carbon Emissions, or a ‘Zero Carbon’ focus. (This particularly for nation’s like NZ with strong and diverse Biocapacity Balance Sheets.) At an ‘enclosed system’, global level, a ‘Zero Carbon’ goal may have real relevance in solving ‘The Real Problem’, however, given the huge demographic, and biodiversity diversity between the nations of the world, setting ‘Zero Carbon’ goals at a nation level has the potential to delay, deceive, and confuse efforts to solve ‘The Real Problem’. -

The Ecological Footprint Emerged As a Response to the Challenge of Sustainable Development, Which Aims at Securing Everybody's Well-Being Within Planetary Constraints
16 Ecological Footprint accounts The Ecological Footprint emerged as a response to the challenge of sustainable development, which aims at securing everybody's well-being within planetary constraints. It sharpens sustainable development efforts by offering a metric for this challenge’s core condition: keeping the human metabolism within the means of what the planet can renew. Therefore, Ecological Footprint accounting seeks to answer one particular question: How much of the biosphere’s (or any region’s) regenerative capacity does any human activity demand? The condition of keeping humanity’s material demands within the amount the planet can renew is a minimum requirement for sustainability. While human demands can exceed what the planet renew s for some time, exceeding it leads inevitably to (unsustainable) depletion of nature’s stocks. Such depletion can only be maintained temporarily. In this chapter we outline the underlying principles that are the foundation of Ecological Footprint accounting. 16 Ecological Footprint accounts Runninghead Right-hand pages: 16 Ecological Footprint accounts Runninghead Left-hand pages: Mathis Wackernagel et al. 16 Ecological Footprint accounts Principles 1 Mathis Wackernagel, Alessandro Galli, Laurel Hanscom, David Lin, Laetitia Mailhes, and Tony Drummond 1. Introduction – addressing all demands on nature, from carbon emissions to food and fibres Through the Paris Climate Agreement, nearly 200 countries agreed to keep global temperature rise to less than 2°C above the pre-industrial level. This goal implies ending fossil fuel use globally well before 2050 ( Anderson, 2015 ; Figueres et al., 2017 ; Rockström et al., 2017 ). The term “net carbon” in the agreement further suggests humanity needs far more than just a transition to clean energy; managing land to support many competing needs also will be crucial. -
The Water, Land, and Carbon Footprints of Different Human Diets in China

Box 217 7500 AE Enschede The Netherlands THE WATER, LAND, AND CARBON FOOTPRINTS OF DIFFERENT HUMAN DIETS IN CHINA THE WATER, LAND, AND CARBON FOOTPRINTS OF DIFFERENT HUMAN DIETS IN CHINA Summary The demand for agricultural production is increasing significantly due to the growth of economic and population worldwide. The agricultural products have huge impact on water use, land use, and greenhouse gas emissions. This can be quantitatively expressed by three indicators: water footprint (WF), land footprint (LF), and land footprint (CF). While China is the most populated country in the world, the impact of the human food consumed in China is not only within the country but also in other parts of the world where food is imported. In this research, the water, land, and carbon footprints of consumption (퐹푐표푛푠) in China are analyzed for five different diets: the current diet (REF) from the statistics of FAO; a healthy diet (CDG) based on the recommendations by Chinese Nutrition Society; a pesco- vegetarian diet (PES), which includes fish, eggs, and dairy; an ovo-lacto vegetarian diet (OLV), which includes eggs and dairy; and a vegan diet (VEG), which excludes all animal products. While REF has a higher intake of kcal and protein per day than CDG, the other three diets are chosen such that the kcal and protein intake per day equals that of CDG. -

This paper systematically applies land, waterand Biofuel carbon footprint accounting methods to calculate resource appropriation and CO2eq GHG emissions of two Energy scenario energy scenarios. The ‘100% scenario’ is meant as a thinking exercise and assumes a complete transition towards Carbon footprint bioenergy, mostly as bioelectricity and some first-generation biofuel. The ‘SDS-bio scenario’ is inspired byIEA's Land footprint sustainable development scenario and assumes a 9.8% share of bioenergy in the final mix, with a high share of Sustainable development Water footprint first-generation biofuel. Energy inputs into production are calculated by differentiating inputs into fuelversus electricity and exclude fossil fuels used for non-energy purposes. Results suggest that both scenarios can lead to emission savings, but at a high cost of land and water resources. A 100% shift to bioenergy is not possible from water and land perspectives. -
Geoengineering in the Anthropocene Through Regenerative Urbanism
geosciences Review Geoengineering in the Anthropocene through Regenerative Urbanism Giles Thomson * and Peter Newman Curtin University Sustainability Policy Institute, Curtin University, Perth 6102, WA, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-8-9266-9030 Academic Editors: Carlos Alves and Jesus Martinez-Frias Received: 26 June 2016; Accepted: 13 October 2016; Published: 25 October 2016 Abstract: Human consumption patterns exceed planetary boundaries and stress on the biosphere can be expected to worsen. The recent “Paris Agreement” (COP21) represents a major international attempt to address risk associated with climate change through rapid decarbonisation. The mechanisms for implementation are yet to be determined and, while various large-scale geoengineering projects have been proposed, we argue a better solution may lie in cities. Large-scale green urbanism in cities and their bioregions would offer benefits commensurate to alternative geoengineering proposals, but this integrated approach carries less risk and has additional, multiple, social and economic benefits in addition to a reduction of urban ecological footprint. However, the key to success will require policy writers and city makers to deliver at scale and to high urban sustainability performance benchmarks. To better define urban sustainability performance, we describe three horizons of green urbanism: green design, that seeks to improve upon conventional development; sustainable development, that is the first step toward a net zero impact; and the emerging concept of regenerative urbanism, that enables biosphere repair. Examples of green urbanism exist that utilize technology and design to optimize urban metabolism and deliver net positive sustainability performance. If mainstreamed, regenerative approaches can make urban development a major urban geoengineering force, while simultaneously introducing life-affirming co-benefits to burgeoning cities. -
Population Growth & Resource Capacity
Population Growth & Resource Capacity Part 1 Population Projections Between 1950 and 2005, population growth in the U.S. has been nearly linear, as shown in figure 1. Figure 1 U.S. Population in Billions 0.4 0.3 0.2 Actual Growth 0.1 Linear Approximation - - - H L Year 1950 1960 1970 1980 1990 2000 2010 Source: Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. World Population Prospects: The 2010 Revision. If you looked at population growth over a longer period of time, you would see that it is not actually linear. However, over the relatively short period of time above, the growth looks nearly linear. A statistical technique called linear regression can create a linear function that approximates the actual population growth over this period very well. It turns out that this function is P = 0.0024444t + 0.15914 where t represents the time variable measured in years since 1950 and P represents the (approximate) population of the U.S. measured in billions of people. (If you take statistics, you’ll probably learn how to obtain this function.) The graph of this linear function is shown in the figure above. (1) Just to make sure that you understand how to work with this function, use it to complete the following table. The actual population values are given. If you are working with the function correctly, the values you obtain should be close to the actual population values!

An Exploration of Human Population Demographic Data
Tested Studies for Laboratory Teaching Proceedings of the Association for Biology Laboratory Education Vol. 32, 406–421, 2011 Behind the Numbers: An Exploration of Human Population Demographic Data Teresa C. Weglarz Department of Biological Sciences, University of Wisconsin – Fox Valley, 1478 Midway Rd, Menasha WI 54952 USA ([email protected]) Increasingly global population size has been a cause for alarm among scientists. Currently, global population size is 6.9 billion and estimates for 2050 range from 8-12 billion. It is estimated that the majority of population growth in the next 50 years will be in developing countries. This computer-based lab activity explores some of the social, economic, and political factors that influence population growth. Understanding the role of these factors in popula- tion growth is critical to the study of population demography. Population demographic data provides a glimpse into the population characteristics that are associated with rapid growth. The International Data Base provides popula- tion pyramids and demography data, on infant mortality rates, fertility rates, and life expectancy of populations in over 200 countries. This population demographic data provides a glimpse into the population characteristics that are associated with population growth and may provide clues on how to address population growth. Keywords: Population growth, demography, population pyramids Introduction Introduction Human demography is the study of population charac- tion data contains estimates and projections for more than teristics. The purpose of this computer investigation is to 200 countries, which includes population size, fertility, analyze the demographic relationships between different mortality and migration rates.
