The truth about Global warming
For every study you find explaining the realities of global warming you can find an equal amount of studies that discredit this claim. What are we to believe? Most people will turn to the cold hard facts which means they will analyse cold hard data that point to an obvious increase in the annual mean temperatures over that last fifty or one hundred years.
The human factor
Can we rely on this data to tell us the truth regarding global warming? This depends of many factors as well as ones point of view of the impact that humans have had on this planet during their very brief time on earth. The typical human being tends to overestimate our impact on the planet if you consider our very brief existence in the complete timeline of our planet that is literally measured in billions of years.
What is the real impact of our existence on the planet knowing that human industrialization has only been active for a few hundred years? The truth about global warming can also to point in a different direction if you consider that the human race has only been producing green house gases for a few hundred years.
Are Humans causing global warming?
Over 2000 scientists would say yes. Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapour, carbon dioxide, methane, and nitrous oxide, all greenhouse gases that help trap heat near earth's surface.
What are the consequences of global warming?
The evidence is quite compelling and the “fear factor” will hopefully influence people to take action. The truth about global warming can be seen in its impact on the environment. Arctic ice is quickly disappearing and the possibility of an ice free summer in the Arctic by 2040 is becoming a reality.
• Indigenous cultures and wildlife such as polar bears are already being affected.
• Glaciers and mountain snows are rapidly melting. In the northern hemisphere, thaws come a week earlier in the spring and freezes begin up to a week later.
• Coral reefs, which are highly sensitive to temperature change, recorded the worst die-off due to stress since 1998.
• An upsurge in the amount of extreme weather events, such as wildfires heat waves and strong tropical storms is also attributed in part to climate change by some experts.
What’s going to happen?
Many reports have indicated that global warming could lead to large- scale food and water shortages and have catastrophic effects on wildlife. Rising sea levels will affect many coastal regions and displace human populations. The effect will be measured on a humanitarian and financial scale.
What do you believe?
Many other studies point to a different cause for global warming. Global warming is seen as a natural part of the earth’s system. An ebb and flow of warming and cooling that happens every 100 000 years or so. There is plenty of evidence to support both claims but in the end it’s up to you to decide what the real truth is about global warming.
