Thinking Globally: ‘How Much Water is on Earth’

From The US Geological Survey:

The largest sphere represents all of Earth’s water, and its diameter is about 860 miles (the distance from Salt Lake City, Utah, to Topeka, Kansas). It would have a volume of about 332,500,000 cubic miles (mi³) (1,386,000,000 cubic kilometers (km³)). The sphere includes all the water in the oceans, ice caps, lakes, and rivers, as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant.

…

The blue sphere over Kentucky represents the world’s liquid fresh water (groundwater, lakes, swamp water, and rivers). The volume comes to about 2,551,100 mi³ (10,633,450 km³), of which 99 percent is groundwater, much of which is not accessible to humans. The diameter of this sphere is about 169.5 miles (272.8 kilometers).

…

Do you notice that “tiny” bubble over Atlanta, Georgia? That one represents fresh water in all the lakes and rivers on the planet, and most of the water people and life of earth need every day comes from these surface-water sources. The volume of this sphere is about 22,339 mi³ (93,113 km³). The diameter of this sphere is about 34.9 miles (56.2 kilometers). Yes, Lake Michigan looks way bigger than this sphere, but you have to try to imagine a bubble almost 35 miles high—whereas the average depth of Lake Michigan is less than 300 feet (91 meters).

1 out of 11: The IEA’s New Report Card on Climate Change and Clean Energy

From The IEA:

While progress is being made on renewable energy, most clean energy technologies are not being deployed quickly enough, the International Energy Agency (IEA) said today in an annual progress report presented to ministers and representatives of nations that together account for four-fifths of global energy demand.

The report, Tracking Clean Energy Progress, highlighted the rapid progress made in some renewable technologies, notably the solar panels easily installed by households and businesses (solar PV) and in onshore wind technologies. In fact, onshore wind has seen 27% average annual growth over the past decade, and solar PV has grown at 42%, albeit from a small base. Even more impressive is the 75% reduction in system costs for solar PV in as little as three years in some countries. This serves as evidence that rapid technology change is possible. Unfortunately, however, the report concludes that most clean energy technologies are not on track to make their required contribution to reducing carbon dioxide (CO2) emissions and thereby provide a more secure energy system.

“We have a responsibility and a golden opportunity to act,” said IEA Deputy Executive Director Ambassador Richard H Jones. “Energy-related CO2 emissions are at historic highs; under current policies, we estimate that energy use and CO2 emissions would increase by a third by 2020, and almost double by 2050. This would likely send global temperatures at least 6°C higher. Such an outcome would confront future generations with significant economic, environmental and energy security hardships – a legacy that I know none of us wishes to leave behind.”

…

The report offers three over-arching policy recommendations for changing this status quo and moving clean-energy technologies to the mainstream market:

• First, level the playing field for clean energy technologies. This means ensuring that energy prices reflect the “true cost” of energy – accounting for the positive and negative impacts of energy production and consumption;
• Second, unlock the potential of energy efficiency, the “hidden fuel” of the future. Making sure that energy is not wasted and that it is used in the best possible way is the most cost-effective action and must be the first step of any policy aimed at building a sustainable energy mix’
• Finally, accelerate energy innovation and public support for research, development and demonstration. This will help lay the groundwork for private sector innovation, and speed technologies to market.

Thinking Globally: ‘Living Planet Report 2012’

From WWF:

The Living Planet Report is the world’s leading, science-based analysis on the health of our only planet and the impact of human activity. Its key finding? Humanity’s demands exceed our planet’s capacity to sustain us. That is, we ask for more than what we have.

A prophetic ad from 1962: “Each Day Humble Supplies Enough Energy to Melt 7 Million Tons of Glacier!”  

The ad, which appeared in Life Magazine, reads:

“This giant glacier has remained unmelted for centuries. Yet, the petroleum energy Humble supplies — if converted into heat — could melt it at the rate of 80 tons each second! To meet the nation’s growing needs for energy, Humble has supplied science to nature’s resources to become America’s Leading Energy Company. Working wonders with oil through research, Humble provides energy in many forms — to help heat our homes, power our transportation, and to furnish industry with a great variety of versatile chemicals. Stop at a Humble station for new Enco Extra gasoline, and see why the “Happy Motoring” Sign is the World’s First Choice!”

Panel: Confronting the Climate Disinformation Campaign

from Sustainability Now Radio:

Here is the video for the free presentation given on April 30, 2012 on Penn State’s University Park Campus. Penn State professors Michael Mann, Donald Brown, Janet Swim and Rick Schuhmann, and graduate student Peter Buckland spoke Monday evening at “Changing the Moral Climate on Climate Change,” a talk that focused on climate change denial. Mann is director of Penn State’s Earth System Science Center and part of the 2007 Nobel Prize-winning Intergovernmental Panel on Climate Change. Susannah Barsom, with the university’s Center for Sustainability, moderated the event, which included a question and answer session.

Canada, Our Changing Climate & ‘The Winter That Wasn’t’

Canada’s environmental agency recently released a weather bulletin reporting that:

The national average temperature for the winter of 2011/2012 was 3.6°C above normal (1961-1990 average), based on preliminary data, which makes this the third warmest winter on record since nationwide records began in 1948.

It also noted that Canada’s:

winter temperatures have been at or above normal since 1997.

The infographic above summarizes some of regional impacts of the winter of 2011/2, a.k.a. ‘The Winter That Wasn’t’.

From The Guardian:

Countries must take urgent steps to value their natural capital – such as forests, peatlands and coastal areas – as part of their economic development, the World Bank has urged.

Placing a monetary value on natural ecosystems is a key step on the road to “green” economic growth, according to the World Bank, which published a report on green growth on Wednesday at a conference in Seoul, Korea.

By making such estimates, countries can develop policies that ensure the pursuit of economic growth does not occur at the expense of future growth potential, by destroying natural assets such as water sources or polluting air, rivers and soil.

Rachel Kyte, vice president for sustainable development at the bank, said that the patterns on which economic growth had been achieved in recent decades were unsustainable, because of the amount of environmental degradation involved.

She said: “At current rates, we are in danger of undermining the basis on which growth has been achieved in the last decades. We do not believe that current growth patterns are sustainable.”

She gave the example of the government of Thailand, which has moved towards more environmentally sustainable growth by attempting to place a value on its mangrove swamps. The exercise has been illuminating – chopping down mangrove for wood gives a return of less than $1,000 per hectare; removing the mangroves to make room for a shrimp farm might generate nearly $10,000 per hectare; but if the mangrove swamps were retained and their importance in providing a barrier against floods was taken into account, they could be valued at more than $16,000 per hectare.

Kyte acknowledged that few countries had so far taken steps to evaluate their natural systems in this way, and said the failure to do so had contributed to countries allowing their environment to be degraded in the pursuit of short term economic growth.
