Ways to save your planet Earth

There are some ways by which you can save your planet Earth.

• you can reduce your

carbon emissions.

• buy energy efficient appliances

+ lightbulbs.

• Change your thermostat( and use clock thermostat )

to reduce energy for heatinng

+ cooling.

• Weatherize your house,

increase insulation, get an energy audit.

• Recycle

• If you can buy a hybrid car.

• When you can, walk or ride a bicycle.

• Where you can, use light rail + mass transit.

• Switch to renewable source of energy.

• Plant trees,

lots of trees.

• reduce our dependence on foreign oil;

help farmers grow alcohol fuels.

• Raise fuel economy standards,

require lower emissions from automobiles.

This is the thing you should see!!!

This what we did to our planet.

What Will The Climate Be Like in 2100?

What Will The Climate Be Like in 2100?

Stanford University climatologist Stephen Schneider discusses what we know and don’t know about the future of the Earth’s climate, and whether it is worth spending trillions of dollars to fight climate change.

What will the Earth's climate be like at the end of this century?

What's the old joke? Prediction is hard, especially about the future. What do you have to do to predict the climate of 2100? Well, you have to know how much CO2, methane, nitrous oxide, aerosols - that's dust and smoke - are going to be there, because that changes what we call the forcing - the pressures on the climate system - to be warmer or colder. We know it's going to be warmer. That's virtually certain.

What are the possible climate scenarios for the end of this century?

Greenhouse gas concentrations double pre-industrial levels and then come down like a steep ski slope because we've invented our way out of the problem with new high technology, and we deploy it starting in 2020. By the end of the century we mearly increased carbon dioxide by, say, 80 percent of pre-industrial levels. That, I'm sorry to say, is a good scenario.

The bad scenario is business as usual. We keep getting richer as fast as we can. We do what we did in the Victorian Industrial Revolution in the rich countries: sweat shops, coal-burning internal combustion engines. Well, what do you think China and India are doing?

Which scenario is likely?

The estimate (for increased temperatures) is between 1.5 and 4.5 degrees Celsius during the next 25 years. Very recently, the IPCC narrowed it to between 2 and 4.5 degrees. They call that "likely." Well, likely means two-thirds to ninety percent. So, that still means there's a 5-7 percent chance it could be "lucky" - below two degrees - or "really unlucky" - above 4.5.

The worst of all worlds is an increase of more than seven degrees. That's an astronomically large number, because an ice age is about six degrees cooler than an interglacial that we're now in. And we're talking about a ten-percent chance it's as large a temperature difference as an ice age to an interglacial cycle, but happening in a century; not in five thousand years.

Global Warming...

What is Global Warming?

Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.

Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years, though, say scientists.

Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years, even.

Earth should be in cool-down-period

But it is not only about how much the Earth is warming, it is also about how fast it is warming. There have always been natural climate changes – Ice Ages and the warm intermediate times between them – but those evolved over periods of 50,000 to 100,000 years.

A temperature rise as fast as the one we have seen over the last 30 years has never happened before, as far as scientists can ascertain. Moreover, normally the Earth should now be in a cool-down-period, according to natural effects like solar cycles and volcano activity, not in a heating-up phase.

Effect of CO2

Greenhouse Gases: Lifegivers and Lifetakers

In what seems like nature’s brutal irony, the gases that make life on Earth possible now threaten our very existence. Read our greenhouse gas profiles and find out why CO2, methane, and nitrous oxide might become benevolent climate killers — and how we can react.

Greenhouse gases heat up our planet. Thy are part of Earth's atmosphere and trap warmth emitted by the sun, thus heating Earth. It is this process – the greenhouse effect – that makes life on the planet possible.

Natural greenhouse gases like carbon dioxide, methane, and nitrous oxide have always been in the atmosphere. Without them, the world’s average surface temperature would be a chilly -18 degrees Celsius. Thanks to the greenhouse effect, however, we enjoy an average temperature of 14 degrees.

Throughout Earth’s history, temperatures have varied greatly, mostly depending on the concentration of greenhouses gases in the atmosphere. All signs now suggest that a major temperature change is happening again, but this time humanity is the cause. Read our gas profiles and learn more about the causes of climate change and how we can reduce them.

Carbon Dioxide - Endless Warming

Carbon dioxide is the number-one reason for man-made climate change. But what is carbon dioxide, actually? Where does it come from? And why are governments and businesses now scrambling to reduce their carbon dioxide emissions?

Carbon dioxide has always been with us. Scientists say Earth’s earliest atmosphere was made up mostly of steam, carbon dioxide, and ammonia from volcanic eruptions. Today, carbon dioxide is mostly produced by the combustion of organic matter like coal, oil, and wood, the fermentation, and the respiration processes of living organisms.

Most CO2 is produced by energy production and transport. Cement production, among many other chemical processes, also releases the gas. Rotting materials release CO2, so landfills are contributors too. People are another source. The air we exhale is made up of about 4.5 percent CO2. Bacteria in the soil release CO2 when they digest leafs and carcasses. Even plants that usually absorb CO2 “exhale” it at night.
