Ancient clams disprove permanent El Niño theory

The prevailing theory and fear that rising global temperatures could result in permanent El Niño conditions have been called into question by an international research team on the basis of growth rings of prehistoric clams. A transition to a permanent … Continue reading

NASA climate model study: Arctic melting linear with temperature

Here’s another climate model study that challenges the Arctic tipping point idea. Arctic melting is still sensitive to temperature rise though and any further increase in atmospheric CO2 will keep translating to further ice loss. According to the new NASA … Continue reading

Climate model shows possibility of multiple years of Arctic sea ice growth – or faster decline

Computer simulations of the US National Center for Atmospheric Research indicate that the natural Arctic climate variability, like seasonal and annual variations in pressure systems, wind patterns and precipitation or cloud cover, could be larger than previously thought.

Lull in upper ocean warming explained through ENSO – warming trend continues

Shortly after an El Niño event there is elevated heat exchange from the upper ocean layers to the cosmos over the tropical Pacific Ocean. In the North Atlantic Ocean, variations in the ocean circulation affect the heat exchange to the … Continue reading

Eemian sea level rise of 8m was 95% meltwater – another paleo warning?

Sounds like there’s new food to calibrate our oceans’ sea level sensitivity. In red the image shows inundations around the Gulf of Mexico under Eemian sea levels. That’s ‘bye bye Houston, New Orleans, Miami.’ Two days ago we looked at … Continue reading

If solar minimum caused Little Ice Age we would have big freeze now

It is often suggested that lower total solar irradiance (TSI) due to a decline in solar activity (less sunspots) was responsible for the Little Ice Age, a period of colder weather conditions from the end of the Middle Ages to … Continue reading
