Scientist predicts new “Maunder minimum” that could herald a new mini ice age

Professor Valentina Zharkova of Northumbria University is predicting that from 2030-2040 the magnetic conditions on the sun will mimic the ‘Maunder minimum’ that occurred from 1645-1715 and produced the Little Ice Age. Read more about her presentation at the Royal Astronomical Society National Astronomy Meeting 2015 here.


Dialing back the 10 foot hype – NOAA Tide Gauge Data shows no coastal sea level rise acceleration

NOAA has just updated its coastal sea level rise tide gauge data including actual measurements through year 2016 which continues to show no evidence of coastal sea level rise acceleration.

Watts Up With That?

… meanwhile California sea level rise “model study” claims 10 foot rise by 2100

Guest essay by Larry Hamlin

NOAA has just updated its coastal sea level rise tide gauge data including actual measurements through year 2016 which continues to show no evidence of coastal sea level rise acceleration.

These measurements include tide gauge data coastal locations for 25 West Coast, Gulf Coast and East Coast states along the Pacific Ocean, Gulf of Mexico and Atlantic Ocean, 7 Pacific island groups and 6 Atlantic island groups comprising more than 200 measurement stations.

The longest NOAA tide gauge data coastal sea level rise measurement record is at The Battery in New York with its 160 year long data record showing a steady rate of sea level rise of about 11 inches per century.


NOAA data provides assessments of the 95% confidence intervals at all measured locations which demonstrate the consistent behavior…

Global temperatures plunge in April – “the pause” returns

Watts Up With That?

Global temperatures have dropped 0.5° Celsius in April according to Dr. Ryan Maue. In the Northern Hemisphere they plunged a massive 1°C . As the record 2015/16 El Nino levels off, the global warming hiatus aka “the pause” is back with a vengeance. He writes:

Some good news to end April, global temperature anomaly has fallen to only +0.1°C today (snapshot) … graphic is like stock market trace

Global Ocean Temperatures Drop To Pre-El Nino Levels

Despite NOAA’s Denial, A Growing Number Of Studies Confirm the Global Warming Hiatus

Despite widespread denial among climate activists, a growing number of scientific research papers in recent months have confirmed the global warming hiatus, trying to explain its possible reasons (for the latest studies see herehere and here).  The latest study claims that the Southern Ocean played a critical role in the global warming slowdown.

I Love Neil deGrasse Tyson, but He is Wrong on Climate

Watts Up With That?

My response to Neil deGrasse Tyson about denial of science.

Guest essay by Donna Hedley

I love Neil deGrasse Tyson. He has done so much to make science interesting and understandable. He is wise and humble. His love for science is infectious. However, I think he is wrong when he talks about the denial of science, especially when it is about climate change.

I agree with him when he says we need to become scientifically literate and that is something I have endeavoured to do over the last few years. I have come to be better understanding of what science is, and how it works. I am not a scientist, but I do have a brain and believe I have come to some intelligent conclusions. Not only that, I am open minded enough to listen to alternative ideas. I want to know the truth, even if it means that someday…
