"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."

"There's currently a very big difference between what the major parties contesting the election are planning to do for our environment. And hopefully there are still plenty of big announcements to come over the course of the election campaign! But if you want to be spared all the somersaults and politicking and just get the facts when they matter, sign up to Envirotracker below for an election-eve update on what the major parties are promising for our environment."

"There's currently a very big difference between what the major parties contesting the election are planning to do for our environment. Here's where the major parties stand as at 12 August 2013. We'll update this snapshot over the course of the election campaign. Hopefully there are some big, positive announcements to come!"

"Monsanto, whose name is synonymous with GM crops, confirmed that it is withdrawing all of its EU applications for approval for new crops. The decision is understood to affect as many as 10 applications for approval for new GM crops. It is understood that Monsanto is pulling all of its applications for crops in frustration at delays over clearing existing crops at EU level."

"Australia's solar landmark Australian solar is celebrating a major milestone, with one million households now equipped with solar PV systems. By the end of 2008 we had less than 20,000 systems installed, illustrating the rapid proliferation of solar across the country. Since then the number of systems installed by year has surged ahead, with 63,378 installations in 2009, 196,308 in 2010, 335,067 in 2011 and 322,447 last year."

Last week the world's atmosphere took a giant leap backward. For the first time in more than 3 million years, the atmospheric concentration of carbon dioxide (CO2) reached 400 parts per million. This was recorded at the National Oceanic & Atmospheric Administration's Earth System Research Laboratory located on Mauna Loa in Hawaii right out in the middle of the Pacific Ocean, a long way from major sources of CO2 in Asia and North America. What this means for the environment is uncertain but it's likely that, if no measures are taken to reduce this level of greenhouse gas, we could be headed for 3-4 degrees C warming globally by the end of this century

"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 world's biggest greenhouse gas emitter, China, has proposed to install a cap on emissions by 2016. The proposal is being hailed as major breakthrough in the push to address global climate change."

"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."

"A research team from the University of Wollongong has declared what it says is a major breakthrough in boosting the potential range of EV batteries."

"The world's biggest wind turbine manufacturer is joining forces with environmental groups in a global campaign to rouse the "silent majority" of people who support renewable energy to fight back against what it claims is "misinformation" spread by some anti-wind activists that is threatening the industry."

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.

Twenty-one coherent major initiatives could together stimulate sufficient reductions by 2020 to bridge the global greenhouse-gas emissions gap.

Finding creative solutions to energy issues has become a major priority for Google co-founder and CEO Larry Page in recent years. For the obvious reasons -- a growing population, increasingly scarce resources, and climate change -- he believes that the corporate world needs to operate more sustainably, and he is determined to build the nation's first zero-carbon company. This means a business that ultimately is so energy efficient and uses so much clean power that it emits no greenhouse gas -- a very tall order indeed. Experts aren't sure whether it's even possible for a company to emit no carbon, but Google is trying to come as close to that goal as possible. "As we became a bigger user of energy, we wanted to make sure we were not just part of the problem, but part of the solution," says Urs Hölzle, Google's employee No. 8 and a senior vice president who oversees the company's green initiatives.

"We've been witnessing a quiet revolution in the wind turbine field with the unveiling at Geelong, in Victoria, of the first Eco Whisper wind turbine, developed by Queensland based company, Renewable Energy Solutions Australia (RESA). The unveiling in Geelong, yesterday, was particularly significant as the major Victorian regional city is making a big play to become a centre for renewable energy in Australia."

"Contrary to many claims, the costs of renewable energy are minor. In 2015, probably the earliest any major changes to the policy could be made, the RET would cost the average household around $1 a week."

"While the news about climate change seems to get worse every day, the rapidly improving technology, declining costs, and increasing accessibility of clean energy is the true bright spot in the march toward a zero-carbon future. 2013 had more clean energy milestones than we could fit on one page, but here are 13 of the key breakthroughs that happened this year."

"The Federal Government has sparked significant debate with the confirmation it intends to move from a fixed carbon price to an emissions trading scheme next year. But where is the description of the long term, low carbon future for Australia? Aside from the 90% renewable energy target proposed by the Greens, the major parties are slim on long-term vision."

"Based on guidance I put together to assist interested laymen, journalists and others trying to understand the knotty problem of wind energy and its health impacts, I've done a very rough application to most of the major pieces of evidence referenced in the discussions. This material will be updated periodically as I assess more material and as new evidence is presented."

"Australia's two major parties have promised to reduce the country's emissions by 5% by 2020, with two different approaches. Labor has used carbon farming as part of its approach; the Coalition is making it a centrepiece. But analysis of Labor's approach shows it is likely to fail, whoever pursues it."
