"By the end of this century, Earth may be home to 11 billion people, the United Nations has estimated, earlier than previously expected. As part of a week-long series, LiveScience is exploring what reaching this population milestone might mean for our planet, from our ability to feed that many people to our impact on the other species that call Earth home to our efforts to land on other planets. Check back here each day for the next installment."

"More than 32 million people fled their homes last year because of disasters such as floods, storms and earthquakes - 98% of displacement related to climate change. Asia and west and central Africa bore the brunt. Some 1.3 million people were displaced in rich countries, with the US particularly affected. Floods in India and Nigeria accounted for 41% of displacement, according to the International Displacement Monitoring Centre and Norwegian Refugee Council"

"A paper published in Nature Climate Change earlier this year challenged a long-standing assumption in both science education and science communication: that increasing science literacy will increase public "acceptance" of the scientific consensus on the risks posed by climate change. The authors surveyed a representative sample of about 1,500 U.S. adults and found that people with an egalitarian-communitarian worldview (roughly liberal) were more likely to perceive climate change to be higher risk with higher levels of science literacy, while for people with a hierarchical-individualist worldview (roughly conservative), higher science literacy scores meant they were more likely to underestimate the risks associated with climate change. If the assumption that science literacy is the solution had held, both groups would have moved toward rating climate change as higher risk as they increased in science knowledge, to line up with current scientific consensus. Instead, increasing science knowledge correlated with increasingly polarized views."

"CREATING AUSTRALIA'S MOST EDIBLE CURB COMPETITION We are people that like our food fresh, local and free. We like social gatherings, designing and building useful things and getting to know neighbours. We empower people like you to RECLAIM THE CURB."

Welcome to the Anthropocene is a website which is designed to improve our collective understanding of the Earth system. The site aims to inspire, educate and engage people about humanity's impact on Earth. Its unique combination of high-level scientific data and powerful imagery will help people visualize and better understand humanity's geographic imprint in recent time. Watch a 3-minute journey through the last 250 years of our history, from the start of the Industrial Revolution to the Rio+20 Summit. The film charts the growth of humanity into a global force on an equivalent scale to major geological processes.

"The interactive maps allow you to zoom in or out, to select a specific mode of transit to examine, and provides a color-coded key as well as roll-over notes that will give you an idea of the percentages of people using that method of travel. Play with the maps of these cities to learn about the transit habits of people in your area. Or, if you're planning on relocating, see if one of these cities accommodates walking and biking to work or if cars rule the roads. There are many ways these interactive maps offer information: we hope they give you some interesting insights!"

"Green Cross Australia helps people adapt to our changing climate, in ways that embrace sustainability and community resilience. We are motivated by our understanding of a resource-constrained, warming planet and our belief that this challenge presents opportunities for a bright future. Our mantra, Think + Act + Share = Change, is key to every project we deliver. We believe the power of our projects is empowering Australians to take practical, informed action. So we don't just focus on awareness, we encourage people to take action, and then give them the tools via social and digital media to share their actions with their friends."

"For the first time ever, environmental groups have staged a mass walkout of a U.N. climate summit. Citing immense frustration with the lack of productive action in the COP19 climate talks, which have been dogged by a persistent rift between rich and poor countries on the responsibility of paying for climate damages, hundreds of people from dozens of environmental groups and movements from all corners of the Earth have voluntarily withdrawn from the talks. According to a spokesperson for Oxfam, around 800 civil society members (which is the label applied to all advocate and activist types at these meetings) have walked out. In a joint statement, group leaders offered that "the best use of their time" was to now focus "on mobilizing people to push our governments to take leadership for serious climate action.""

"People never seem to question science when it underlies something easily valued - like iPhones and other handheld devices. We either take it for granted or celebrate science-based products like G.P.S., Global Positioning Systems, which guide drivers and pilots and allow heavy machinery or a farmer's tractor to be operated with a precision that approaches ballet. And people are always eager to take advantage of the latest advances in medicine."

"There is growing evidence that public opinion about climate change is shifting over time. In many countries, surveys reveal that people are becoming less worried, and in some cases more sceptical about climate change, even while awareness of climate change is increasing."

This report describes the outcomes from a CSIRO global foresight project. It presents six megatrends that will redefine how the world's people live.

It's a youth climate summit. This July, 2,000 young people will come together to shift Australia away from fossil fuels towards renewable energy. Together we can change the game on climate. WHEN, WHERE? Melbourne.  July 13-15th. 

"When people think about green buildings, what generally comes to mind is solar panels, geothermal energy, improved insulation, green roofs, high-performance windows, rain-water recuperation, and so forth. However, the milieu in which the building is rooted also ought to be considered. Although we often forget it, being green also includes what lies beyond the walls! Landscaping, for instance, plays a major role in energy consumption. Trees, plants and the way you take care of them can have a significant impact on GHG emissions, and consequently, on your energy bills."

"The Lucky Country has experienced a major spike in extreme weather in the past few years, with a string of devastating incidents just since January. That has people wondering if the island continent is somehow a perfect bellwether for the Earth's changing climate. So scientists are bearing down on the problem with intensity, investigating Australia's increasingly violent weather patterns and trying to figure out what they might portend for the rest of the world as our climate changes."

"Bryan Welch, author of Beautiful and Abundant, tells Oliver Balch that the way to engage people on sustainability is to be optimistic, hopeful and joyful"

Green has become the common term for people who care about the environment or for practices promoted as better for the environment than some other practices. When used for marketing, "green" can become downright misleading. In fact, there's a term "greenwashing" to describe advertising that makes something look greener than it really is. Sustainable, on the other hand, refers to practices designed to have the least impact on the environment, create the least waste, and capable of being carried out indefinitely. That is, something sustainable can't waste resources, can't pollute, can't be dangerous over the long term to life, can't cost so much that it causes social or financial disruption, etc.

"The majority of the 9 billion people on Earth will live with severe pressure on fresh water within the space of two generations as climate change, pollution and over-use of resources take their toll, 500 scientists have warned."

"Shining a Light on Sustainability is an introductory video from the Australian Research Institute for Environment and Sustainability at Macquarie University, Sydney.  This video introduces the concept of sustainability and explains our current situation even before any potential challenges from climate change are involved.
