Climate Concerns

The "CLIMATE CONCERNS" group is dedicated to discussion regarding the topic of the ever present and serious issue of changes to our climate due to the introduction into the atmosphere of human induced effects which prove harmful to the environment and which eventually may prove destructive to our planet.

Donald, I reviewed your chart and accompanying posts.

You say now, "I posted a chart showing 420,000 years of climate history.  It shows that we are coming out of the last of 5 warming periods.  And while we are nearing the temperature peaks attained by the previous four warming periods.  We aren't there yet. "

It's difficult to see current temperature change in right side of your chart, given the scale.

Here's a similar chart which expands the last part, and adds the expected changes in temperature due to greenhouse gases.

The Medieval Warm Period temperature reconstruction varies according to the location sampled.

A number of studies that have attempted to produce very large spatial-scale reconstructions have come to the same conclusion: that medieval warmth was heterogeneous in terms of its precise timing and regional expression ...

The evidence currently available indicates that NH mean temperatures during medieval times (950–1100) were indeed warm in a 2-kyr context and even warmer in relation to the less sparse but still limited evidence of widespread average cool conditions in the 17th century (Osborn and Briffa, 2006). However, the evidence is not sufficient to support a conclusion that hemispheric mean temperatures were as warm, or the extent of warm regions as expansive, as those in the 20th century as a whole, during any period in medieval times… [emphasis mine]

Northern Hemisphere Temperature Variability

Ok, Joan.  We can use your chart.  It shows exactly the same as the chart I posted on page 10 of this thread (Vostok Ice Core Data).  The period between each of the four previous peaks is about 120,000 years.  Since man was not on this earth during those previous  peak periods , what caused them?  And why is it man's fault this time?

And those precipitous drops are entries into the next ice age.  Sooo....Maybe we better hope global warming is man's fault.  The earth cannot grow enough food to feed the world's population during an ice age.

Donald, you can't expect us to get off the climate change topic when the issue is not settled. As long as you and others deny humans play a part in changes taking place in the climate we will continue to supply you with new information. All the top temperatures that I see have a precipitous drop. 

Want to wait around and see who wins this dispute?

I would be more proactive observer, skilled

Ruth, on page 10 of this thread, I posted a chart showing 420,000 years of climate history.  It shows that we are coming out of the last of 5 warming periods.  And while we are nearing the temperature peaks attained by the previous four warming periods.  We aren't there yet.  Mankind was not on this earth duiring the previous four warming periods, and yet they warmed along the same general trend as what we are experiencing today.  How can you possibly blame mankind for the warming cycle this time?  Our Industrial Revolution would be about the width of a hair at the end of that chart.  Can we please get off the "Climate Change" routine?  Mankind has nothing to do with it.

I am for clean air.  I am against acid rain, smog, and all the other atmospheric problems that are bothering our cities.  And we are working toward electric cars which will help tremendously in this regard.  If you look up the ingredients of smog, you will see that CO2 isn't even mentioned.  From Wikipedia:

Smog is a type of air pollutant. The word "smog" was coined in the early 20th century as a portmanteau of the words smoke and fog to refer to smoky fog, its opacity, and odour.[1] The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid 20th century. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxides, ozone, smoke or particulates among others (less visible pollutants include carbon monoxide, CFCs and radioactive sources).[citation needed] Human-made smog is derived from coal emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.

That is the stuff I want the EPA to clean up.

Comment by Ruth Anthony-Gardner on December 10, 2016 at 7:47pm

I'm a bit confused, Donald. You're for the EPA protecting clean air and water, unless it's a global scale threat from climate change? Is that because one country alone can't completely combat global threats? Are you in favor of an international effort to counter such threats, like the Paris Accord? But EPA actions directly impact our ability to do our part in cooperative actions.

Comment by Donald L. Engel on December 10, 2016 at 4:24pm

No, Ruth.  Just that part that concerns "man-made" global warming.  I'm sure you're not surprised at that, since it is what I've been saying for the last year, or two.

I'm all for keeping the air clean.

Comment by Ruth Anthony-Gardner on December 10, 2016 at 1:40pm

So you're in favor of eliminating the EPA, Donald?

Comment by Donald L. Engel on December 10, 2016 at 12:54pm

I think it's the first thing Trump has done right.  He had Al Gore in to give his spiel on "Man-made" global warming, and then confirmed his choice was Pruitt.

The apparent decision to put Oklahoma state attorney general Scott Pruitt in charge of the EPA is “like putting an arsonist in charge of fighting fires”.    Sierra Club
