    South Western Michigan

I'm not sure if observations from my area are valid due to the substantial influence Lake Michigan has on our local weather.  That being said, this spring has been unusually cool and rainy.  The weather here tends to be extremely localized.  Every one who lives here has a story about driving from blue skies and sunshine, into some brutal extreme weather event (torrential rain, hail, gale force winds, total white out blizzard like snow) and back into blue skies in 15 minutes, through a weather system that was only 10 miles wide.  It is not uncommon to get blasts of straight line winds in thunderstorms that flatten crops, uproot trees and damage buildings that may only last for a minute or so and be only several hundred yards wide. 

What is more concerning is the apparently increasing range of the swings in temperature and precipitation, (it is currently 65 F, 15 degrees below normal for July with yet more rain) the seemingly randomness of it, on agriculture. 

For what it's worth, this winters unusually cold temps and heavy snow fall seem to be just the thing for the local climax mixed deciduous forest.   Maples were coming up almost literally as thick as the grass in my lawn this spring and I am still pulling walnut, cherry and elm seedlings out of my garden.

    It’s good to re-check older conclusions

There has already been a lot of discussion on this forum on Guy McPhersons blog, and his conclusions are pretty much discounted here – but is that wise? Do we take a reading from a dynamic system just once?

One thing I will say for Guy, is that he updates his sources regularly, and if you are paying attention, almost weekly yet another piece of compelling evidence is added.

If you haven't read the climate change update blog in a while, I strongly encourage you to take a look again and specifically check the newer sources which align with his theory.

Possibly something to bring back into the discussion? Specifically the Calthrate gun aspect?

I don’t think he adds “compelling” evidence, Rudy. He adds evidence but, from some of the criticisms I’ve read, and from my own research, he doesn’t always interpret the evidence correctly, nor does he show how his hypothesis (it isn’t a “theory”) follows from the evidence; he basically just says it does.

As far as I can tell, there is no conclusive evidence that the clathrate gun has fired (and McPherson claimed it fired 7 years ago). There are a few worried scientists, but not conclusive, or even compelling, evidence so far. It just doesn’t seem to have happened, from the methane readings we’ve been seeing over the last 7 years.

    California getting drier

California drought takes significant step drier:

[quote]Increasingly, drought indicators point to the fact that conditions are not appreciably better in northern California than in central and southern sections of the state. In addition, mounting evidence from reservoir levels, river gauges, ground water observations, and socio-economic impacts warrant a further expansion of exceptional drought (D4) into northern California. For California’s 154 intrastate reservoirs, storage at the end of June stood at 60% of the historical average. Although this is not a record for this time of year—the standard remains 41% of average on June 30, 1977—storage has fallen to 17.3 million acre-feet. As a result, California is short more than one year’s worth of reservoir water, or 11.6 million acre-feet, for this time of year. The historical average warm-season drawdown of California’s 154 reservoirs totals 8.2 million acre-feet, but usage during the first 2 years of the drought, in 2012 and 2013, averaged 11.5 million acre-feet.

Given the 3-year duration of the drought, California’s topsoil moisture (80% very short to short) and subsoil moisture (85%) reserves are nearly depleted. The state’s rangeland and pastures were rated 70% very poor to poor on July 27. USDA reported that “range and non-irrigated pasture conditions continued to deteriorate” and that “supplemental feeding of hay and nutrients continued as range quality declined.” In recent days, new wildfires have collectively charred several thousand acres of vegetation in northern and central California. The destructive Sand fire, north of Plymouth, California—now largely contained—burned more than 4,000 acres and consumed 66 structures, including 19 residences.[/quote]

Given the rest of the nation's dependence on California's agricultural products, how soon do our food prices rise more strongly than they already have?

    AGW sending normal patterns haywire

Have you seen this one yet Doug?

http://m.dailykos.com/story/2014/07/30/1317666/-Megadrought-Huge-Surge-of-Pacific-Heat-Fails-to-Start-El-Nino-Heats-Planet-to-3-Warmest-Months

Heat from the largest Kelvin wave ever seen along the equator in the Pacific ocean has moved poleward, heating the subtropical and temperate Pacific waters.

It's starting to look like Climate Change is affecting the way El Nino works……  good for us in Australia if it means we avoid a drought, but terrible for you guys.

Also, I recently saw another story where winds had gone from the Pacific Equatorial region, through the Bering Straight, over the N Pole, and into the Atlantic, which goes completely against everything I've ever learned about wind patterns before.

Of course, AGW sending normal patterns haywire is exactly what has been predicted.

    Smokey Greenland Sees Another Summer of Substantial Melt

According to our best understanding of paleoclimate, at current greenhouse gas levels of 402 parts per million CO2 and 481 parts per million CO2e, the Greenland Ice Sheet eventually melts out entirely. It’s a level of atmospheric heat forcing we’ve already set in place, a level that keeps rising at a rate of about 2.2 parts per million CO2 and 3 parts per million CO2e each and every year due to our ongoing and reckless carbon emissions. And it’s a level that is already starting to receive substantial additions from destabilizing permafrost carbon together with likely increasing releases from sea bed methane stores.

Greenland Cumulative Mass Loss Through Late 2013

(Greenland cumulative mass loss through mid 2013. Data provided by the GRACE satellite gravity sensor. Image source: NOAA.)

It is this ongoing overall mass loss that tells the ice sheet’s full tale. One that now includes an ever-increasing number of destabilized glaciers speeding more and more rapidly seaward.

    Oops. New Science Paints (Very) Different Picture.

Just when you thought that you had it all figured out-guess what happens?

I am going to upset everyone. But that is just your Ego. Control it.

In this series of videos a simple assumption is made and experimented on to reveal a totally different Universe. Actually it is only a little TOE (Theory of Everything) as it does not cover Quantum Erasure.

Tom Campbell covers the big TOE in these Spanish Lectures.

Let me get back on track. There is no way to break this to you gently. So I will hit you with it right between the eyes. The sun's energy is not nuclear. It is electric. And it can turn down at any moment.

Let us begin at the beginning of our story.

    New farms

Let us know when the ice is gone from those Viking farms and maybe they will come back.
