The sun is the closest star to earth and is the center of solar system. A very hot gas in form of giant ball. It is fueled by nuclear fusion reactions. The light from it heats our planet and that is what makes life possible. It displays sunspots, solar flares, erupting prominences and coronal mass ejections. These factors are related to sun’s magnetic field, which impact our near earth space environment and determine space weather
What is climate?- It is a warming heat as a result of heat trapping greenhouse gases which are increasing dramatically in the atmosphere.
- It is a measure of the average pattern variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over a periods of time. (Wikipedia- the Free encyclopedia}
Causes of Climate-
- Earth’s temperature is a balancing act-between energy entering and leaving the planet system.
Changes in solar energy, volcanic eruptions and natural changes in greenhouse concentrations.
- Greenhouse effect changes affects earth atmosphere.
When sunlight reaches earth’s surface, it can either be reflected back into space or absorbed by earth, and if absorbed, it releases some of the energy back into the atmosphere as heat (infrared radiation).
- Sun’s energy variations reaching the earth.
How much energy reaches the earth, includes changes of sun orbit in the earth. The intensity of sunlight can either warming in periods of stronger solar intensity or cooling in times of weaker solar intensity.
- Reflectivity of earth’s atmosphere and surface.
Melting of sea ice or increases in cloud cover are contributing factors too. So as volcanic eruptions also, due to dust and particles it emits, but for a period of time only. Vegetation absorb carbon dioxide, much illegal logging, and replacing it with industrial buildings, ocean currents carry heat around the earth. These are among which contributes climate change in our planet.
Climate change is the biggest environmental and humanitarian crisis of our time. With above overloaded heat trapping carbon dioxide, really threatens a large disastrous in climate.
What Are The Effects Of Climate Changes On Planet Earth?
It will include more frequent wildfires, longer periods of drought in some regions and increase in number and duration of tropical storms resulting to floods.
Shrunk of glaciers, ice on rivers and lakes breaks up earlier, plants and animal ranges have shifted and early blooms of trees flowers. Rise of sea level accelerated and intense heat waves.
Evidence indicates that the net damage and costs of this climate change is likely to increase more and more as time goes on.
In Latin America-gradual replacement of tropical forest in eastern Amazon putting significant risk of biodiversity loss through species extinction. Changes in availability of water for human consumption, agriculture and energy generation.
Europe- inland flash floods risk, more frequent coastal flooding, erosion due to storms and sea level rise, glacial retreat in mountain areas, snow cover will reduce in winter, much loss of species and productivity of crop will have reductions.
Africa-by 2020, between 75 and 250 million people are projected to be exposed to stress due to increase in water level, a 50 percent yield reduction in agriculture production which include also to food access would be severe.
Asia-Central, South, East and Southeast Asia by 2050, fresh water availability to decrease. Coastal areas will be at risk due to increased flooding, death rate from related to floods and drought is expected to some regions.
What Are The Possible Solutions For Fast Climate Changes?
Forgo Fossils Fuels-eliminating the burning of coals, oils and natural gas. This is the most intimidating challenges worldwide for businesses who are residents in rich countries. It is their very lives, sustaining them a vast wealth, enjoyment in life. Even passing it thru out their generations. So as the nations they are occupying, the benefits they derived out of their business. Sacrificing the worst results from it or totally ignores it.
There is no perfect solution for these, according to them and scientist. There are some alternatives being given and trying out if effective as possible solutions.
Plant derived plastics, windmills and biodiesel are some being introduced.
Infrastructure upgrade-buildings structure all over the world are contributors, one third contributors. But energy sufficient and improved cement making processes could reduce green gas emissions.
Move Closer To Work-burning a single gallon of gasoline produces a 20 pounds of CO2. Bicycle is a form of transportation with human energy only. Weekly transport for workers to cut cost of fuel transportation or move closer to work and take a walk.
Consume Less-lessen transport time such as weekly or monthly going to groceries or outings. Plastic recycling or avoiding using it if possible.
Be Efficient-cutting off electricity if not needed as in home and office lights, ventilated windows for home and offices and industries. Weatherproof of windows for countries having cold season. Efficient cars which consume less fuel.
Eat Smart- eat green and leafy vegetables, fruits. Corn, meats, consumes large amount of oil for fertilizers and chemicals.
Cutting down Of Large Trees-33 millions acres of trees are cut down, 1.5 billion tons of carbon dioxide are emitted and represents 20 percent human made greenhouse gas emissions.
Improving agricultural productions, strict implementations of laws regarding forest protections, full control of logging or right forest management. Paper recycling. Planting new trees for every trees that had been cut.
Unplug Chords Connectors- for all electronic devices if not in use. It consume more electricity even gadgets are off as long as it is attached to plug.
One Child Policy-population today is 6.6 billion now and expected to rise for 9 billion more this coming decades. It would take 54 acres to sustain human being from place to dwell, food clothing, medicines, water, fuel energies. Having a one child policy is impossible.
Future Fuels-replacing fossils fuels is a great challenge to face by this generations and scientist. Fuel derives from plants such as Ethanol, electrolyzed out of water, solar energy panels and others.
That of such derived from plants, would cause high costs of foods. So many feasible things are still being studied.
Experiment Earth-there is this so called Geoengineering radical interventions to either block sunlight or reduce greenhouse gases.
It needs human full cooperation to all of these laid up possible control. But the truth facts, many don’t care and just mind their own pleasure, life.
Well, when things comes to its peak, just wrap around our arms to our waist and stare.
