Why 2012 was a bad year for the Arctic and all of us

by Steve Williams             August 9, 2013

During 2012, the Arctic broke several climate records, including a level of unprecedented warmth that created rapid ice loss.
The National Oceanic and Atmospheric Administration is warning in its "The State of the Climate in 2012″ report that last year was one of the 10 hottest since the beginning of recording global average temperatures.
In addition to this, Arctic sea ice melted to reach record lows during the annual summer thaw. To illustrate this, the report points out that in Greenland, around 97% of the region's ice sheet melted: this a figure that is four times the expected figure based on the melt in previous years. We're still feeling the effects of this and continued warming today, with the North Pole Environmental Agency issuing a warning that the summer ice has melted so fast and by so much that a shallow lake has formed.
Also, greenhouse gas emissions rose to worrying levels. In early May, the carbon dioxide ratio in the Earth's atmosphere exceeded 400 parts per million in readings taken at Hawaii's Mauna Loa Observatory — this is! thought to be the highest concentration in millions of years.
"Many of the events that made 2012 such an interesting year are part of the long-term trends we see in a changing and varying climate — carbon levels are climbing, sea levels are rising, Arctic sea ice is melting, and our planet as a whole is becoming a warmer place," Acting NOAA Administrator Kathryn D. Sullivan, Ph.D is quoted as saying.
This year marks the 23rd edition of the report, which is produced as part of a suite of climate services offered by NOAA for the U.S. government and wider academic research.
Other concerning observations recorded in the report include a continued rise in sea levels that reached a record high in 2012 — this even withou! t the contributing effects of the phenomena known as La Nina that saw a significant rise in 2011.
At the same time, rising ocean salinity trends have continued.
Ocean salinity (the concentration of salt water) levels were first observed changing significantly in 2004 when saltier than average readings in areas like the North Pacific were recorded, while there were fresher than average readings in high precipitation areas including the north central Indian Ocean. This trend continued in 2012. What this means in its simplest terms is that precipitation is increasing in already wet areas while evaporation is intensifying in drier locations.
For instance, Brazil saw its worst drought in the past three decades, according to the report, while the Caribbean had! an extremely wet dry season. Furthermore, the Sahel region of Africa saw record precipitation and flooding during its wet season, while nearly 87% of the American West saw drought conditions.
Sullivan is quoted as saying these findings "caution us, perhaps, to be looking at a likely future where extremes and intensity of some extremes are more frequent and more intense than what we have accounted for in the past."
However, the report did yield a small piece of encouraging news. The NOAA analysts found that the climate in Antarctica remained "relatively stable overall." Also, the warm air actually allowed a further positive in that 2012 saw the second smallest ozone hole observed in t! he past two decades.
This, of course, does not ameliorate the worrying trends observed throughout 2012 but does illustrate that when we talk about climate change, it is a complex picture.
Perhaps, to put this in perspective, the final word should go to John P. Abraham, professor of thermal sciences at the University of St. Thomas in St. Paul, Minnesota, who was not involved in this study but who says it is a firm answer to climate change deniers:
"The latest 'State of the Climate' report shows that the Earth continues to heat, the atmosphere is heating, the worldwide ice loss continues, and other symptoms of our warming planet march ! forward, without cessation. A lot of people claim that global warming has magically stopped, but the facts, and the Earth, continue to disagree."

Top 22 Benefits of Trees


Here are 22 of the best reasons to plant and care for trees or defend a tree’s standing:

Trees combat the greenhouse effect
Global warming is the result of excess greenhouse gases, created by burning fossil fuels and destroying tropical rainforests. Heat from the sun, reflected back from the earth, is trapped in this thickening layer of gases, causing global temperatures to rise. Carbon dioxide (CO2) is a major greenhouse gas. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when you drive your car 26,000 miles.

Trees clean the air
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.

Trees provide oxygen
In one year an acre of mature trees can provide enough oxygen for 18 people.

Trees cool the streets and the city
Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.

Trees conserve energy
Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50 percent. By reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.

Trees save water
Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.

Trees help prevent water pollution
Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.

Trees help prevent soil erosion
On hillsides or stream slopes, trees slow runoff and hold soil in place.

Trees shield children from ultra-violet rays
Skin cancer is the most common form of cancer in the United States. Trees reduce UV-B exposure by about 50 percent, thus providing protection to children on school campuses and playgrounds - where children spend hours outdoors.

Trees provide food
An apple tree can yield up to 15-20 bushels of fruit per year and can be planted on the tiniest urban lot. Aside from fruit for humans, trees provide food for birds and wildlife.

Trees heal
Studies have shown that patients with views of trees out their windows heal faster and with less complications. Children with ADHD show fewer symptoms when they have access to nature. Exposure to trees and nature aids concentration by reducing mental fatigue.

Trees reduce violence
Neighborhoods and homes that are barren have shown to have a greater incidence of violence in and out of the home than their greener counterparts. Trees and landscaping help to reduce the level of fear.

Trees mark the seasons
Is it winter, spring, summer or fall? Look at the trees.

Trees create economic opportunities
Fruit harvested from community orchards can be sold, thus providing income. Small business opportunities in green waste management and landscaping arise when cities value mulching and its water-saving qualities. Vocational training for youth interested in green jobs is also a great way to develop economic opportunities from trees.

Trees are teachers and playmates
Whether as houses for children or creative and spiritual inspiration for adults, trees have provided the space for human retreat throughout the ages. 

Trees bring diverse groups of people together
Tree plantings provide an opportunity for community involvement and empowerment that improves the quality of life in our neighborhoods. All cultures, ages, and genders have an important role to play at a tree planting or tree care event.

Trees add unity
Trees as landmarks can give a neighborhood a new identity and encourage civic pride.

Trees provide a canopy and habitat for wildlife
Sycamore and oak are among the many urban species that provide excellent urban homes for birds, bees, possums and squirrels.

Trees block things
Trees can mask concrete walls or parking lots, and unsightly views. They muffle sound from nearby streets and freeways, and create an eye-soothing canopy of green. Trees absorb dust and wind and reduce glare.

Trees provide wood
In suburban and rural areas, trees can be selectively harvested for fuel and craft wood.

Trees increase property values
The beauty of a well-planted property and its surrounding street and neighborhood can raise property values by as much as 15 percent.

Trees increase business traffic
Studies show that the more trees and landscaping a business district has, the more business will flow in. A tree-lined street will also slow traffic – enough to allow the drivers to look at the store fronts instead of whizzing by.

Reduce your water bill with a rain barrel!

Also help reduce harmful runoff with rain water harvesting.

If you are not ready to install a green roof yet, you can achieve some of the same benefits with a low-cost solution: a rain barrel, which captures rain water that would otherwise run off of your roof.
One of the main benefits is to reduce the amount of stormwater runoff. Typically rain water flows off roofs, driveways, parking lots and other "impervious surfaces" into storm drains, which discharge either into community sewer systems or into nearby streams. In the first case, rain over-burdens sewers, leading to overflows that can contaminate public swimming beaches. In the latter case, rushing stormwater can erode stream banks, introduce pollutants and ruin habitat for fish and other aquatic life.
A second benefit is for your wallet. You can use water captured in rain barrels to irrigate your lawn and garden, saving on utility bills. (In water-stressed regions, or during droughts, this water-conservation technique may be a necessity, given the imperative to conserve water.)
The drier the climate, the more water gets dumped outdoors, according to research by Aquacraft. In the desert Southwest, as much as 60% of home water usage occurs outdoors, whereas the figure is as low as 20% in wetter regions, like the Northeast. In summer, not surprisingly, the percentage of water used outdoors spikes, as we water lawns and gardens.
As Environmental Work Group recently pointed out, if we use tap water to irrigate, we're essentially wasting our own tax dollars, which have gone toward treating that liquid to drinking water standards.
Commercial rain barrels can be attractive, and can be built to prevent mosquito breeding and make hooking up gardening hoses easy. But you can also make your own rain barrel (The Environmental Protection Agency offers a how-to pdf. Some of the commercial options on the market include:
> Smartware's 48-gallon recycled plastic rain barrel with a classic look ($119 at amazon.com)
> Algreen's 65-gallon plastic rain barrel, clay-like appearance and space for a containter garden ($151 at amazon.com)
> Great American Rain Barrel's handsome 60-gallon barrels can be easily linked to increase storage capacity ($199 at gaiam.com)
> Grow and Make's 50-gallon barrel made from recycled olive oil bins ($150 at worldofgood.com)
> SpringSaver's 51-gallon rain barrel, in five styles ($130 at burpee.com)
> Santa Fe's 47-gallon rain barrel, in a terracotta-style finish ($149 at gardeners.com)
> Gardener Supply Co.'s faux sandstone 75-gallon rain barrel ($199 at gardeners.com)
Also, Woot.com (daily deals) often has rain barrels at good prices!

Bust Runoff with a Rain Garden

By Brian Clark Howard

Homeowners and businesses can stem the tide of polluted runoff threatening our waterways by setting up a simple "rain garden," which is beautiful as well as beneficial.
The concept of a rain garden, which mimics natural systems, was crystallized in Maryland in the 1990s. The idea is to create a depression filled with plants that collects the rainwater that runs off a building and its landscape. The plants — such as sedges, rushes, ferns, wildflowers, shrubs, trees and so on — absorb the water and release it slowly. This reduces the surge of water running off the landscape, which picks up fertilizers, pesticides, motor oil and other contaminants and carries them into waterways.
Rain gardens reduce the risk of flash floods, and they help stabilize the flow that enters waterways, both in terms of volume and temperature. That leads to healthier streams and rivers. Plus, the plants naturally filter the water, neutralizing some of the toxins that are present. They also provide valuable wildlife habitat.
No two rain gardens are exactly the same. They can be large and interconnected, with different levels and features, or very small and simple. Normally, they are placed in natural low spots, near where gutters drain. Ideally, they are populated with plants that are native to the local area. Sometimes they have swales to maximize their ability to hold water. Get tips on starting one here.

Tree Thursday - 5 Ways to Look at a Tree

5 Ways to Look at a Tree


1. Commodity   According to the Wisconsin Paper Council, an "interesting rule of thumb is that an acre of forested land may yield an average of 10-15 cords of wood when harvested at maturity—depending not only on the size of the trees, but how productively the land has been managed." One "cord" could typically yield any of the following:

  • 12 dining room table sets (seating eight)
  • 250 copies of the Sunday New York Times
  • 942 one-pound books
  • 460,000 personal checks
  • 4,384,000 postage stamps
  • 7,500,000 toothpicks
2. Oxygen Source             One estimate: Over a 50-year lifetime, a tree generates $31,250 worth of oxygen and provides $62,000 worth of air pollution control. The process is rather fundamental: During photosynthesis, a tree "inhales" CO2 from the air and then separates the carbon from the oxygen molecules. The carbon is absorbed by the tree, which then "exhales" pure oxygen back into the air for us to breathe. In the process just described, trees also serve as carbon sinks, e.g. as Wise Geek tells us, trees "naturally absorb carbon dioxide for photosynthesis, sequestering the carbon and converting it into mass while releasing the oxygen back into the atmosphere." Such carbon sinks offset carbon dioxide emissions and reduce climate change.
3. Home               From nearly microscopic insects to camouflaged reptiles to feathered friends to wily primates and beyond, each tree is a vast, thriving eco-system in and of itself. The destruction of even a single small tree not only disrupts natural cycles, it also sentences countless creatures to death. More than 1000 different species of insects have been living in just one kind of rainforest tree.
4. Flood Prevention        Deforestation negatively impacts the amount of water in the soil and groundwater and the moisture in the atmosphere. Without tree roots to hold soil in place and fight erosion, we are seeing more runoff and less sediment deposit after storms. This results in higher levels of chemicals in our water and far more flooding. Over the course of a half-century, a single tree can recycle $37,500 worth of water and controls $31,250 worth of soil erosion.
5. Beauty             As Henry David Thoreau says: "I frequently tramped eight or ten miles through the deepest snow to keep an appointment with a beech-tree, or a yellow birch, or an old acquaintance among the pines."
"The best time to plant a tree was 20 years ago. The next best time is now."
(Chinese Proverb)
