The Madden-Julian Oscillation: a weather system Wikipedia lists under Climate Change

by Robert W. Endlich

A significant weather system which affects the globe was not even discovered until the 1970s, perhaps because it is stronger in the Southern Hemisphere than the Northern. This system, the Madden-Julian Oscillation, is an area of enhanced rainfall with these characteristics:

The enhanced precipitation anomaly starts in the Indian Ocean; it always moves eastward, and usually moves from Indian Ocean into mid-Pacific at speeds of 9-19 Miles/Hour. In addition to the enhanced precipitation area itself, there is an associated area of suppressed precipitation, an out-of-phase area ahead of it, usually way out ahead of it. The disturbed weather areas usually last 30 to sometimes 90 days.

The convective precipitation signature of this system is strongest within 15 degrees north and south of the Equator. Continue reading “The Madden-Julian Oscillation: a weather system Wikipedia lists under Climate Change”

Climate F-Words

by Roy W. Spencer, Ph. D.

[Ed.  Dr. Roy Spencer wrote a post (22 March 2018) disagreeing with Lord Monckton’s theory that climate scientists have over-estimated feedback by a factor of 2, because they have been using the feedback  equations incorrectly.  Dr. Spencer agrees with the factor of 2 error, but he disagrees with the reason given by Lord Monckton.  In response, Lord Monckton has countered Dr. Spencer’s argument with a post of his own on Spencer’s blog.  The original Spencer post can be found here with Lord Monckton’s counter argument  here.]

recent article by Lord Christopher Monckton over at WUWT argues that there has been an “elementary error of physics” that has led to climate sensitivity being overestimated by about a factor of 2.

I agree with the conclusion but not the reason why. It is already known from the work of Otto et a (2013), Lewis & Curry (2015) and others that the climate system (including the deep oceans) has warmed by an amount that suggests a climate sensitivity only about half of what the models produce (AR5 models warm by an average of 3.4 deg. C in response to a doubling of CO2).

But the potential reasons why are many, and as far as I can tell not dependent upon Christopher’s arguments. For those who don’t know, Lord Monckton is a pretty talented mathematician. However, like others I have encountered over the years, I believe he errs in his assumptions about how the climate research community uses — and does or does not depend upon — the concept of feedback in climate modeling.

A 1D Model Of Global Temperature Changes, 1880-2017

Dr. Roy Spencer

[Dr. Spencer’s post originally appeared on his blog on February 22nd, 2018.  The link to his 2/23/18 update of the post is here.]

UPDATE(2/23/18): The previous version of this post had improper latitude bounds for the HadCRUT4 Tsfc data. I’ve rerun the results… the conclusions remain the same. I have also added proof that ENSO is accompanied by its own radiative forcing, a controversial claim, which allows it to cause multi-decadal climate change. In simple terms, this is clear evidence the climate system can cause its own, natural, internally-generated climate changes. This is partly what has caused recent warming, and the climate modelling community has assumed it was all human-caused. Continue reading “A 1D Model Of Global Temperature Changes, 1880-2017”

More rational policies in our future?

Trump’s Paris decision challenges bad science, economics and energy politics behind treaty

Paul Driessen

In the wake of President Trump’s exit from the Paris climate treaty, reactions from other quarters were predictably swift, nasty, sanctimonious and hypocritical.

Al Gore paused near one of the private jets he takes to hector lesser mortals to say the action will bring “a global weather apocalypse.” Billionaire Tom Steyer got rich selling coal but called the President’s action “a traitorous act of war.” Actor-activist Mark Ruffalo railed that Trump has “the death of whole nations on his hands.” Michael Moore said the action was “a crime Continue reading “More rational policies in our future?”

A Brief Look at Climate Models Developed by Skeptics

Skeptical modelers show a more realistic view of past, present, and future climate change that follows mostly natural temperature patterns. These models indicate a more benign climate outcome than do the IPCC models. Since they are able to bound the problem of cause and effect, they dramatically reduce the wide uncertainty range of expected global temperature increase due to atmospheric CO2 concentration.

Bernie McCune

When Alarmists say “climate change is real!” I think yes it is, but “real . . . what?” My perhaps flippant answer to that question is real normal, real natural . . . among a few.  I think human caused climate change is real small.  These are some of the real issues that I want to explore here.

The first point is that the Intergovernmental Panel on Climate Change (UN IPCC) climate models are actually not real at all.  In fact based on the real data, they are turning out to be fairy tales.  Based on the real data, more realistic models are now being developed by very qualified groups and individuals. The improvement in modeling results over those by the IPCC appear Continue reading “A Brief Look at Climate Models Developed by Skeptics”
