El Niño Development Looking More Likely Now

By Anthony Watts – Re-Blogged From WUWT

ENSO-neutral conditions still reign as of the beginning of the month, but we’re starting to see some clearer signs of the development of El Niño.

Forecasters estimate that El Niño conditions will develop in the next few months, and there’s a 70-75% chance El Niño will be present through the winter.  Most computer models are currently predicting a weak El Niño event.

Solar Cycle Wave Frequency Linked to Jet Stream Changes

By Francis Tucker Manns, PhD – Re-Blogged From WUWT

It’s not the heat It’s the humidity 

Abstract: The sun controls climate change. Not industry. Not you. Not me. It is the sun.

Solar cycle 24, the weakest in 100 years, is stumbling to an end. The sunspot cycle averages about 11 (± 1.5) years. There may not be any sunspots this week. In the spring of 2017 the sunspot number was low or zero and Canada was plagued with spring floods from melting snow and heavy rainfall.

Weather and Climate in the Real World

By Dr. Tim Ball – Re-Blogged From WUWT

My overall career interest is the impact of weather and climate on human history and the human condition. Much of this involved the impact on primary industries like agriculture, forestry, and fisheries. For 17 years I produced monthly columns titled Weather Talk in the largest circulation farm magazine in Canada, Country Guide. Despite the popularity with the farmers and agribusiness, I was fired because I wrote about what was wrong with the science of the global warming issue. Shortly after ending with Country Guide I began a similar column in a magazine called The Landowner and have produced monthly columns for several years now. Beyond the sin of disagreeing with the official government position on anthropogenic global warming (AGW), I spoke out about the failure of Environment Canada to improve forecasting for farmers or even consider their specific needs. While they were doing that, the Auditor General of Canada identified they spent $6.8 billion in a seven-year period (1998-2005) on climate change that produced nothing. It produced worse than nothing because a portion of the money was spent on the Canadian climate model that contributed to the IPCC amalgam of models; as Ken Gregory showed, its projection was the worst of all of them (Figure 1).

405 Thousand Year Climate Cycle Discovered Related to Earth’s Orbit Around the Sun

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

In ancient rocks, scientists see a climate cycle working across deep time.

A repeating shift in Earth’s orbit spans hundreds of millions of years

From THE EARTH INSTITUTE AT COLUMBIA UNIVERSITY

Scientists drilling deep into ancient rocks in the Arizona desert say they have documented a gradual shift in Earth’s orbit that repeats regularly every 405,000 years, playing a role in natural climate swings. Astrophysicists have long hypothesized that the cycle exists based on calculations of celestial mechanics, but the authors of the new research have found the first verifiable physical evidence. They showed that the cycle has been stable for hundreds of millions of years, from before the rise of dinosaurs, and is still active today. The research may have implications not only for climate studies, but our understanding of the evolution of life on Earth, and the evolution of the Solar System. It appears this week in the Proceedings of the National Academy of Sciences.

Plateau in Ocean Air Temps

– Re-Blogged From Science Matters

Years ago, Dr. Roger Pielke Sr. explained why sea surface temperatures (SST) were the best indicator of heat content gained or lost from earth’s climate system.  Enthalpy is the thermodynamic term for total heat content in a system, and humidity differences in air parcels affect enthalpy.  Measuring water temperature directly avoids distorted impressions from air measurements.  In addition, ocean covers 71% of the planet surface and thus dominates surface temperature estimates.
