According to NASA, the hottest year on record was 2005, which matched 1998. Twice in the last ten years, we’ve had the hottest temperatures on average ever recorded in our planet’s history. That is very likely more than just a coincidence.
In fact, the past nine years have all been among the 25 warmest years on record, a streak which is unprecedented in the historical record. For that to happen, it’s likely there has to be an underlying factor, and that factor seems to be global warming.
U.S. and global annual temperatures are now around 1.0 F degrees warmer than they were in 1900. The rate of warming has accelerated over the past 30 years, increasing at a rate of three times faster than the century-scale trend. It’s likely the increase in CO2 emissions has something to do with that rate increase.
According to an MIT study, there’s been a 100% increase in the intensity and duration of hurricanes and tropical storms since the 1970s, most likely due to the increased amount of CO2 emissions to our atmosphere, which has increased the Earth’s surface temperature, and warmer weather is believed to increase the intensity of tropical storms and hurricanes.
In fact, the levels of atmospheric carbon dioxide has increased by 31% between 1800 and 2000, going from 280 parts per million to 367 parts per million. Scientists predict that carbon dioxide levels could be as high as 970 parts per million by the year 2100.
According to the National Climactic Data Centre estimates, $100 billion of damage was caused by hurricanes hitting the U.S. coast in 2005 alone. The increase in severity of the hurricanes and tropical storms is most likely due to the increase of CO2 emissions, which heats up the Earth’s near-surface temperatures. In fact, the average surface temperature has increased by about 0.6 C (1.0 F) over the last 100 years. This is likely why snow cover and ice extent have decreased over the past few decades.
According to the U.S. Geological Survey predictions, Glacier National Park will have no glaciers left by the year 2030, further showing the rapidity of global warming and the impact it can have on our planet in the very near future.
According to the Arctic Climate Impact Assessment, 400,000 square miles of Arctic sea ice have melted, which is threatening polar bear habitats and further accelerating global warming worldwide. That amount of Arctic sea ice is approximately the size of the state of Texas, and we’ve lost that in just the last 30 years, further emphasizing that we need to take action now before the damage becomes too severe for our efforts to really matter.
The sea level has risen by 4?-8? (10-20 cm) over the past 100 years, which is likely due to the melting of the polar glaciers, which is likely due to the increase in the Earth’s near-surface temperature, and that’s being increased by the increase in CO2 emissions into Earth’s atmosphere. This can lead to devastating effects for coastal communities because the sea level is rising, which means that when the sea comes in-tide, more erosion can occur, and if coastal communities are present, more damage done to them. In addition, losing the glaciers reduces the amount of usable fresh water on our planet.
It is also projected that 15-37% of all plant and animal species could be wiped out by global warming by the year 2050, which could further cause considerable damage to our planet’s ecosystem.
The United States is ranked nr.1 among large nations of being a global warming polluter, contributing 25% of emissions, even though the U.S. only makes up 5% of the world’s population. This provides more evidence that the U.S. Government must do more to combat global warming. In fact, six former U.S. Environmental Protection Agency (EPA) leaders say that the U.S. is not doing enough to fight global warming. The fact that there have been NO bills passed by the U.S. Congress to cut global warming pollution further confirms what many EPA leaders are saying.
As you can see, there is statistical evidence that proves that global warming is causing changes to our planet, and changes that will do more harm than good. Governments and individuals need to pay close attention to these statistics in order to figure out ways to reverse the disturbing trends that are now occurring. The sooner we take heed of these statistics and implement changes that address global warming, the quicker we can reverse the disturbing trends and the less damage will occur to our planet and way of life.

Do you want to help the environment but find that it’s too much trouble to recycle? With these easy tips, you’ll find that recycling takes a minimal amount of time to save our resources.
1. Keep a recycling bin handy and make it easy to recycle. It takes only seconds to toss an empty bottle, plastic container or can into a bin. Keep it in a nearby closet or in the garage.
2. Recycle paper. Use paper grocery bags or cardboard boxes to hold the paper. When going through the mail toss unwanted junk mail into the recycling box. Reuse blank sides of paper for notes, or grocery lists.
3. Reuse plastic grocery bags. Many grocery stores now offer an incentive to customers who bring in their own bags, offering cents off per bag. Keep the bags in the car for easy access.
4. Old bed sheets or blankets make great drop cloths for painting, arts and crafts or household repairs.
5. Spread coffee grounds and fireplace ashes in the garden to add extra nutrients to the soil.
6. Grind lemon rinds in the garbage disposal to keep it smelling fresh.
7. Plastic fruit cups can be used for small jobs around the house such as painting, cleaning or polishing.
8. Don’t throw away clothing or household items that are in good condition. Donate them to charity. Many charities will pick up your items.
9. Use plastic containers from margarine and whipped topping for leftovers.
10. Worn cotton items such as towels, washcloths or socks make perfect cleaning, dusting or polishing rags.

With the energy crunch impacting virtually everyone worldwide today, the timing for a green building environment is just right. People have begun their own efforts to become environmentally and earth friendly, with reuse, recycle, and renew projects in the communities and on their own. It is only natural that these efforts are being extended to basics, such as building and construction activities.
Most people are familiar with green products, safe, non-toxic, recycled items such as cleaners, plastic park benches, and other conservation efforts. In buildings, you can find the green building environment at work when you see solar rooftop panels, or water barrels catching rainwater runoff for reuse in yards and gardens. Some buildings use hard packed gravel for parking lots, which will allow water absorption, instead of solid blacktop or concrete.
Some large buildings are now taking advantage of rooftop gardens and green roofs, that are planted with highly water retaining materials like moss. Or, the roofs are designed to minimize rainwater runoff. Materials for construction can be green if they include rapidly renewable plants like straw, bamboo, certified sustainable forests, recycled stone and metal. Other products used are non-toxic, or renewable or recyclable. These would include materials made from sheep wool, recycled plastic or papers, adobe brick, clay, cork, coconut or other woody fibers, sandstone, and so on. There is an effort to save on shipping and gasoline use by purchasing materials locally when possible, or nearby to the building locations.
The green building environment is seen in the manner in which buildings are constructed, as they are designed to make full use of renewable energy sources including solar and wind power. Buildings are planned for directional use of natural light and heat sources so that passive solar energy can be utilized. They are built with roofs designed to hold solar panels, with enough space facing the sunward side so that adequate amounts of panels can be installed effectively and with maximum sunlight absorption capability. Added attention is given to insulation use and special sun control on windows, as well as placement and size of windows to take advantage of passive solar heat energy.
Combinations of solar, wind and hydrogen power systems are used to get maximum benefit from naturally occurring, free, energy generating resources. Interior lighting and appliances are super efficient, using Energy Star appliances, and CFL and LED lighting, combined with automation systems. Solar heat panels for hot water can reduce water heating costs. Some buildings use solar roof tiles, to provide maximum collection of sunlight energy for generators. Indoors, the use of special filtering and air cleaners, non-smoking rules, and plants helps keep air fresher, cleaner, and less toxic.
The final component of the green building environment is to consider disposal of waste products in an environmentally friendly manner. Reduction of waste, recycling of waste, and separation facilities for reusable waste completes this earth friendly effort. With demand increasing, and prices coming down with that increased demand, this technology is a natural to spread worldwide.
