STOP CALLING SURFACE "COOLING" GLOBAL COOLING ! ! !

Yesterday a casual google search triggered a flurry of recent stories from a spectrum of news outlets, most with breathless headlines about two years of global temperature drop - that leaves me stupefied.  Too many of these stories with all their handwringing and confused writing either ignore or bury the fact that they are discussing Earth's surface temperatures.  Why can't we get the simplest principles straight?  It's the atmospheric insulation silly!  Right, Left, malicious and well-meaning, what up?  We live upon a Global Heat and Moisture Distribution Engine!

Our Surface Temperature represents about 10% of our Global Climate Engine's total heat content.  The oceans contain the other 90% of global climate temperatures, for christ sake stop ignoring that!  Enunciate how our planet operates.  Surface temperatures fluctuate, distribution patterns of surface heat are immensely complex, so what?  The fundamental physical reality that no one cares to hammer home is that our global heat and moisture distribution engine is accumulating a known amount of extra warming 24/7/365 and the reasons are well understood, and the amounts are well known.

But don’t take my word for it, listen to a real expert Josh Willis PhD explain the deniable, but unavoidable, physical reality.   First a quickie, then another talk with a bit more details, followed by some visualizations of Earth’s temperature rise to put these fluctuations into realistic perspective.

Charting Irreversible Climate Change with Jason-3

NASA Jet Propulsion Laboratory    Streamed live on Feb 12, 2015
As humans drive Earth's climate into a new regime, it is critical to keep our fingers on the pulse of the planet. Sea level rise is both a stark reminder of our impact on the climate and its impact on us. The oceans capture over 90 percent of the heat trapped by greenhouse gases, expanding as they warm. 
They also collect water from melting glaciers and ice sheets, making sea level rise a doubly important indicator of global warming. Without adaptation, a 2-meter rise would displace 187 million people worldwide. Sea level will continue to rise, but how fast? Like its predecessors, Jason-3 will serve as our eyes on sea level rise. Measuring global sea level once every 10 days, it will chart out the global rise of the oceans--a rise that is unlikely to subside or reverse for generations. 
But Jason-3 will be more than a sentinel of climate change. It will also measure the tilt of the ocean surface providing oceanographers with information about ocean currents, measure wind and waves helping forecasters predict marine weather, and even find local warm spots that can intensify hurricanes.

Scientists rule out imminent sun induced cooling of climate
December 6, 2018, CESSI - phys.org


The sun's activity influences environmental conditions in space adversely affecting satellites and space-based technologies such as telecommunications and navigational networks. The sun is also the primary natural source of energy for the Earth's climate. The sun's activity level changes but predicting these changes has been challenging. Now a team of two scientists from the Center of Excellence in Space Sciences India at IISER Kolkata has come out with a prediction for the upcoming sunspot cycle which reveals the expected conditions in space over the next decade. Their research work appears today in the journal Nature Communications. …

… Their ensemble forecast surprisingly suggests it could even be stronger than the cycle which is just ending. They expect the next cycle to start rising in about a year following the end of the current sunspot cycle minimum and peak in 2024. Bhowmik and Nandi predict space environmental conditions over the next decade would be similar or slightly harsher compared to the last decade. They find no evidence of an impending disappearance of sunspot cycles and thus conclude that speculations of an imminent sun-induced cooling of global climate is very unlikely.
