A Geological Perspective of Polar Bears

By David Middleton – Re-Blogged From WUWT

A Popular Narrative

Polar bears (Ursus maritimus) are the poster child for the impacts of climate change on species, and justifiably so. To date, global warming has been most pronounced in the Arctic, and this trend is projected to continue. There are suggestions that before mid-century we could have a nearly ice-free Arctic in the summer. This increases the urgency with which we must act to reduce our greenhouse gas emissions to delay or avoid some of the worst consequences of climate change.

Modern Warming – Climate Variability or Climate Change?

By Renee Hannon – Re-Blogged From http://www.WattsUpWithThat.com

Introduction

In the mid-1900’s many scientists were suggesting the Earth was cooling. Now scientists are forecasting global warming. Indeed, instrumental data shows global temperatures warmed by approximately 1-degree C during the past 165+ years. With warming rates of 0.5 to over 1.3 degrees C per century this has caused considerable alarm for many. This recent warming is commonly attributed to increasing greenhouse gases, primarily CO2.

This post examines natural paleoclimate trends and simple characteristics of past and present climate cycles at different time scales. Data suggests distinct differences between short-term climate variability and longer-term climate change. This is important because short-term climate variability can be misinterpreted as underlying climate change resulting in poor science and potentially worse policy decisions. This post compares modern instrumental trends to paleoclimate trends. This comparison reveals modern warming has characteristics of natural short-term climate variability and not long-term climate change.

Lindzen, Soon and Spencer debunked?

By Andy May – Re-Blogged From http://www.WattsUpWithThat.com

On Bret Stephens facebook page, I [complimented] Mr. Stephens on what I thought was a very good column. I also noted that the eminent climate scientist Dr. Richard Lindzen had said similar things. To this a George Smith replied, in part, as follows:

“Few “skeptics” have been debunked as much as Lindzen and Spencer.”

Link to comment here.

If you follow the link you will see it is followed with a google search for “Lindzen debunked.” No support, no data, no peer reviewed references, just anything that says “Lindzen debunked.” This is “internet slime” at its worst. We see a lot of this sort of reprehensible behavior around climate science, often by people who have no scientific background at all. But, I am a scientist with 42 years’ experience and have been studying and writing about climate science for years, so I do want to address some of the scurrilous attacks found in this google search.

First Peoples: The Warming Alarm-Dog That Didn’t Bark

By Alec Rawls – Re-Blogged From http://www.WattsUpWithThat.com

Beneficial climate change allowed modern humans to emigrate out of Africa and spread around the globe says the new PBS documentary “First Peoples,” but it fails to mention that the era it designates as “good times” was several degrees warmer than today.

A critical moment in human history is intoned with intense drama (21:08-21:52 here):

The movement of prehistoric people was affected by the climate, which fluctuated over thousands of years.

I turned up the volume, knowing that if there was anything a warming alarm-dog could find to bark about, it was about to be featured front and center.

In bad times the Sahara was an un-crossable barrier, but in good times, when the climate was wet, the desert disappeared. Any adaption that emerged in one part of Africa could spread to other parts of the continent….

In the Climate Debate, Hear Both Sides

By Christopher Monckton of Brenchley – Re-Blogged From http://www.WattsUpWithThat.com

In May 2015, the Pennant, a biannual magazine for retired UK armed forces personnel, carried an article entitled The Earth’s Climate by Rob Varley, chief executive of the Met Office, the world’s oldest national weather bureau.

The Met Office article does not represent a fair or balanced summary of the science on the climate question. This detailed response, prepared at the suggestion of a reader of the Pennant, is illustrated with some 50 well-sourced graphs that are intended to be clear at a glance. The key facts that restore balance to the discussion may be gained from these graphs in five minutes.

Why Current Climate is Anomaly, and Ice Age Climate is Normal Earth’s Climate

Re-Blogged from TheWatchers.Adorraeli.com

The Ice Age isn’t coming, because it is already here. According to author and researcher Rolf Witzsche the Ice Age Climate is the normal climate for the Earth and it has been for more than 85% of the last million years. Because glaciation has been the normal state of the climate, the glacial epoch has been named Pleistocene Epoch. Our present, nicely warm period is the anomaly in this epic icy landscape. The entire development of what we call civilization has occurred in this climate anomaly.
