The Alternative View to Global Warming – What is Your Opinion?

Glen Luckman Alternative View to Global Warming By Ettaariane Wilson

Scientific evidence behind Global warming is being seriously challenged.

In sharp contrast to the theory that we face unprecedented disasters across the planet, some scientists dispute that global warming is caused by mankind.

They believe Global warming is a natural occurring event that follows this process every few hundred years. They also believe the predicted disasters will not be as severe as we have been led to believe.

Neither party is in the position to refute the fact that Global warming is increasing.

We are therefore in the horns of a dilemma. Do we ignore the increase of carbon dioxide and other gases in our atmosphere because it is a ‘natural occurrence’ or, do we do our best to reduce our carbon footprint all over the planet. If we take the latter path then our carbon footprint needs to be reduced by 80% and quickly.

However, this cannot happen without total Government co-operation world wide. It also needs the full co-operation of the people of this planet: recycle, recycle, recycle.

Lets open our own Court and look at the evidence of both parties.

We will begin with the theory that the Greenhouse effect is the end result of the burning of fossil fuels since the beginning of the Industrial revolution. Firstly, we need to have a clear idea of exactly what the Global warming effects are and how they are affected by the burning of fossil fuels, if,indeed,they are.

Global warming is caused by the increase of average temperature of Earths air and oceans. This began in the mid-20th century and is mainly believed to be caused by a concentration of greenhouse gases,(carbon dioxide, nitrous oxide and methane), in turn, caused by de-forestation and the burning of coal and other fossil fuels.

The heat from the sun is trapped in the Earths atmosphere and can’t get out. This greenhouse effect is good if it is controlled. However, if there are too many gases in the atmosphere then plants, animals and people will die.

Global warming is affecting the planets ecological system and causing breaks in the food chain. Other effects are wild weather systems: floods, typhoons, hurricanes, tsunamis, earthquakes. Etc. It also causes acid rain which, in turn, gradually destroys everything it touches.

Greenhouse gases are caused mainly through our need for electricity and transportation sending chemicals to pollute air, water and land, into the atmosphere. This ties in with the start of global warming commencing in the mid-20th century with new factories and transport around the globe.

Other causes of greenhouse gases are burning rubbish at landfill tips, and cutting down trees that would otherwise remove the carbon dioxide from the atmosphere, using electrical equipment in our homes and driving our cars when we could walk.

This is a tiny simplistic list of manmade causes of global warming, yet, this tiny list makes a significant difference to the amount of greenhouse gases in our atmosphere.

If you believe that mankind is the cause of global warming then you can help to reverse the effects in many ways. There are numerous websites on the internet and books in the local library plus advice from councils and agencies to help you decide how you can help the Earth by reducing your carbon footprint.

Let us take a look now at the evidence provided by the scientists who believe Global warming isn’t caused by mankind but is a natural occurrence, happening every so many hundred years.

In the other camp, scientists state, among other things, that this episode of global warming is just taking the temperature of the Earths atmosphere back to what it was in Medieval times. They also argue that the magnitude of the gas emissions involved is inadequate to answer to the magnitude of the Earths temperature increase.

They state: the climate change is controlled by cyclical eccentricities, which run in 100,000, 21,000, 11 year and 206 year cycles, in Earths orbit and rotation plus differences in the heat output of the Sun. Greenhouse gases just contribute in a very minor way.

Also attributable are atmospheric causes due to clouds, polar ice caps and volcanic dust. Tectonic causes-landmass movement, oceanic currents and sea floor spreading also contribute.

During the last hundred years two cycles of warming and cooling have occurred and we are in the second warming cycle. A fact that is seemingly well hidden from us.

The Important Differences Between “Climate Change” and “Global Warming”

By: James Nash

Many people in the media (and elsewhere) use the terms “climate change” and “global warming” interchangeably, as if they were the same thing. But there are differences between the meanings of the two terms.

Getting a better handle on the definitions of and differences between “global warming” and “climate change” will help us understand why the threat caused by continued warming of the planet is so serious.
Planet Earth’s current warming trend is based largely on natural warming and cooling cycles that have been happening for eons; as well as human-caused additions to greenhouse gases, which are boosting the atmosphere’s ability to trap heat in the biosphere. Minor factors like an overall increase in the sun’s solar intensity play a smaller role.

While greenhouse gases are an essential component of a livable planet – they’re what keep Earth from being a lifeless ball of ice – humans are causing greenhouse gas levels to increase so quickly that it’s causing the average global temperature to rise much faster than it would naturally. This warming is predicted to lead to a variety of negative effects, including:

1) Melting (and possible disappearance) of glaciers and mountain snow caps that feed the world’s rivers and supply a large portion of the fresh water used for drinking and irrigation.

2) A rise in sea levels due to the melting of the land-based ice sheets in Greenland and Antarctica, with many islands and coastal areas ending up more exposed to storm damage or even underwater.

3) Increasingly costly “bad weather” events such as heat waves, droughts, floods, and severe storms.

4) Lowered agricultural productivity due to less favorable weather conditions, less available irrigation water, increased heat stress to plants, and an increase in pest activity due to warmer temperatures.

5) Increases in vector-borne infectious diseases like malaria and Lyme Disease.

6) Large numbers of extinctions of higher-level species due to their inability to adapt to rapidly changing climate and habitat conditions.

The first two of these effects are mostly related to increasing average temperatures. Items 3-6 are related to heat too, but also playing a role are non-temperature factors – i.e. “climate-change factors.”

Climate change is about much more than how warm or cool our temperatures are. Whereas “global warming” refers to increasing global temperatures, “climate change” refers to regional conditions. Climate is defined by a number of factors, including:

1) Average regional temperature as well as day/night temperature patterns and seasonal temperature patterns.

2) Humidity.

3) Precipitation (average amounts and seasonal patterns).

4) Average amount of sunshine and level of cloudiness.

5) Air pressure and winds.

6) Storm events (type, average number per year, and seasonal patterns).

To a great extent, this is what we think of as “weather.” Indeed, weather patterns are predicted to change in response to global warming:

1) Some areas will become drier, some will become wetter.

2) Many areas will experience an increase in severe weather events like killer heat waves, hurricanes, flood-level rains, and hail storms.

It’s tempting to think that all of these changes to the world’s climate regions will average out over time and geography and things will be fine. In fact, colder climates like Canada may even see improved agricultural yields as their seasonal temperatures rise. But overall, humanity has made a huge investment in “things as they are now, where they are now.”
