Read here. What are the symptoms of a "consensus" crumbling? In a startling admission, which appears to be a subtle stab-in-the-back of NASA's Hansen's approach, an EU scientist said the following:
“To date, when trying to explain tropical climate variations, we have always looked upwards, specifically to the atmosphere. Our new data, for the first time, direct our attention towards the depths of the ocean, thereby opening new perspectives for our scientific approach,”
Over the past few decades climate research has been stuck-on-stupid with the James Hansen's CO2 hypothesis, and his CO2 driven climate models, that force every climate variation through the myopic vision of the CO2 ideology.
Unfortunately for climate science and policymakers, the trace gas CO2 has about squat to do with climate variation, which galactic sums of research money and effort have been wasted on. It now seems the atmospheric CO2-cult is being abandoned with scientists finally seeking answers from both the oceans and solar-related activity.
"Climate variability in the tropical Atlantic Ocean is determined by large-scale ocean–atmosphere interactions, which particularly affect deep atmospheric convection over the ocean and surrounding continents. Apart from influences from the Pacific El Niño/Southern Oscillation and the North Atlantic Oscillation, the tropical Atlantic variability is thought to be dominated by two distinct ocean–atmosphere coupled modes of variability that are characterized by meridional, and zonal, sea-surface-temperature gradients and are mainly active on decadal and interannual timescales...we report evidence that the intrinsic ocean dynamics of the deep equatorial Atlantic can also affect sea surface temperature, wind and rainfall in the tropical Atlantic region and constitutes a 4.5-yr climate cycle."
