Our greatest accomplishment has been the creation of the world’s largest network. A network of goods and services that have weaved into everyone’s life on Earth. But it seems that this very existence has produced a by-product. The increase in greenhouse gases has driven temperatures to soar. Global warming is a worldwide phenomenon and scientists are looking at environmental records. It’s hard to keep the books! If there isn’t a foundation.
When you think of all the diversity in the world, all the knowledge we’ve retained along the way. There’s been enough time for our civilization to deliver new scientific findings. Our generation is in an information age and we’re loving it! Since Global warming is threatening life on Earth it’s a relief that we have Science. Science has given us the facts that can give us the cutting edge we need to change. When we need to change. We hope.
Global warming and Science
Graphs are what scientists use to show information easily. Up until now, the media has shown only one temperature graph. The hockey stick graph is the one that has garnered attention. The only one that’s heralded as the most accurate and the truth! The one which has escalated our state of panic and increased our consciousness for the fight in global warming. We’re asked to panic, change our actions, and lower the carbon footprint!
Recently there has been a call to unite behind the Science! Greta Thunberg, a notorious Climate activist has influenced millions! She says,
“Do our own homework and then we’ll realize that we need a new way of thinking.”Greta Thunberg
So, like anyone looking to learn and do their part in the fight against global warming, I try.
I try to keep my mind open to different scientific opinions. Educated opinions that have significant value in the fight to reduce global warming. Then along the way, something surprises me! I learn about a Canadian Professor with his own Climate graph! Though, I had assumed there was only one!! Yet, it makes sense there would be more than one! There are many climatologists actively publishing historical temperatures!
Mann VS Ball
These Scientists have worked to create a larger historical picture of the Earth. Generations of painstaking hours in research and testing passed down. However, instead of coming together to study the differences and outcomes of opposing data. Scientists are dragging each other down, discrediting and even name-calling!
Two such Scientists with differing opinions in Historical Climatology have fought in the Supreme court recently. Michael Mann and Tim Ball they’ve both studied climate change and its effects on human history.
The graph below shows just how different the studies have turned out to be. Michael Mann’s graph shows that global temperatures have been fairly constant through time except for the most recent past. The telltale hockey stick graph shows how temperatures have recently soared into unchartered territory.
Tim Ball’s version shows quite a different picture where he found the past was subject to many variations in temperature both high and low. He paints the picture of Midevil times being quite a bit hotter than today`s temperatures. The “anti-alarmist” say that Mann’s graph has defied the Intergovernmental Panel (IPCC) on Climate change.
They state the IPCC’s previous assessment on historical temperatures also had warmer and cooler periods. But, as of 2001, the IPCC only supports Michael Mann’s graph. They support the graph because it shows the human-caused rise in CO2 levels. Plus, Mann was their Lead Author in the IPCC third assessment report. Did representation of temperatures ever come from a Proxy graph at the IPCC
The Proxy graph was created by different researchers and represents their efforts in different color lines. This graph shows the warming trend in Mideviel times and the little ice age that occurred directly afterward. Climate proxies are measurements gathered from the tree rings, coral, ice core samples and Stalactites. It’s another way for scientists to gain more knowledge of past temperatures. In times when no one was using thermometers!
The method of using a Climate proxy is not as accurate as using a thermometer. This is why there are always variations in climate graphs. Its the only way to gain insight into historical temperatures from thousands of years ago
Trials and consequences
The opposition between Mann and Tim Ball brought my attention to Ball’s graph. He sued Dr. Tim Ball in the British Columbian Supreme court. In 2011, the renowned Scientist sued him and a Canadian think tank called Frontier Center for Public Policy for defamation of character. What triggered the lawsuit was Tim Ball’s statement “Mann belongs in the State Pen, not Penn State.” Ball asserts that this statement was said in an attempt to get Mann to show his math.
However, throughout the eight-year trial, Mann did not release his data. The judgment was passed down as the judge felt the case was neither proved nor disproved. Mann showed bad faith, therefore the courts ruled in favor of Ball awarding him legal costs. Mann plans to appeal the decision and the court case could go on!
They’ve both worked tirelessly to map out temperatures in an effort to decipher if the world has ever been this warm. A path science blazed in order to understand our atmosphere. Not one man is 100% right in the Science of climatology but many are close. The outcome suggests humans are responsible for the increase in CO2 levels. 97-98% of Climate Scientists believe that global average surface temperatures have risen in the past century.
