There are 5 comments on the Erie Times News story from Apr 7, 2013, titled Guest Voice: Northwest Pa. needs to fight climate change. In it, Erie Times News reports that:

Since the dawn of the industrial revolution and the advent of the fossil-fuel-based energy economy, mankind has dramatically changed the chemical composition of the atmosphere.

Climate change is not an abstract concept.

It is here.

It is now.

And most of all, it requires action.

.
.....
........
..........

Here are some of the scientific questions at the core of this issue:

Is the climate changing? Of course.

The climate always has changed and always will.

Is the earth getting warmer? We should hope so for at least two reasons:

First, the world emerged from the Little Ice Age in the 19th century, so it would be worrisome if it weren’t getting warmer.

Second, all the history indicates that humans thrive more during warmer periods than colder ones.

It is likely, though, that earth has warmed less than many official temperature records indicate for a variety of reasons,

including:

few long-term records from either the southern hemisphere or the 71 percent of the planet that is covered by water;

distortions from the urban heat-island effect and other faulty siting (e.g.,

temperature sensors next to asphalt parking lots, etc.; the decline in weather station reports from Siberia after the fall of the Soviet government; the arbitrarily ceasing to include measurements from northern latitudes and high elevations, etc.)

.
.

The most accurate measures of temperature come from satellites.

Since the start of these measurements in 1979, they show minor fluctuations and an insignificant net change in global temperature.

Is the earth getting dangerously warm?

Probably not, since the earth was warmer than it is now in 7000 of the last 10,000 years.

By the way,

does anybody know what the

“right”

amount of global heat is?

Some governments, and skeptics that man-made climate change is a big problem, argue that the slowdown in the rising trend shows less urgency to act.

Governments have agreed to work out, by the end of 2015, a global deal to combat climate change.

Last year was ninth warmest since records began in the 1850s, according to the U.N.'s World Meteorological Organization, and 2010 was the warmest, just ahead of 1998.

Apart from 1998, the 10 hottest years have all been since 2000.

Guemas's study, twinning observations and computer models, showed that natural La Nina weather events in the Pacific around the year 2000 brought cool waters to the surface that absorbed more heat from the air.

In another set of natural variations, the Atlantic also soaked up more heat.

"Global warming is continuing but it's being manifested in somewhat different ways," said Kevin Trenberth, of the U.S. National Center for Atmospheric Research.

Warming can go, for instance, to the air, water, land or to melting ice and snow.

Warmth is spreading to ever deeper ocean levels, he said, adding that pauses in surface warming could last 15-20 years.

"Recent warming rates of the waters below 700 meters appear to be unprecedented," he and colleagues wrote in a study last month in the journal Geophysical Research Letters.

The U.N. panel of climate scientists says it is at least 90 percent certain that human activities - rather than natural variations in the climate - are the main cause of warming in recent decades.

While less dramatic in Erie, we are already experiencing the effects of a changing climate.

Erie Mayor Joe Sinnott has taken an important first step by signing the U.S. Conference of Mayor's Climate Protection Pledge.

The McAbee Fossil Beds (Tranquil Shale, Cache Creek) are some 50 million years old (Eocene).

These shales are sediments of a shallow lake that existed at a time when the Northern hemisphere had a warm temperate climate.

The fossil record shows that this was a time when palm trees grew as far north as Alaska.

Some five dozen plant species have been described from the Tranquil shale,

including more than 40 Broadleaves

and some 17 Conifer species.

Sassafras,

katsura

and both Ginkgo plant fossils have been found,

as well as a diversity of insects,

fish fossils,

and even some feathers.

One of the most climate change alarmist-supportive media outlets in the world is having second thoughts, based on reality. http://www.telegraph.co.uk/earth/environment/...
