The mainstream and long-held view of clouds in relation to climate change is that clouds are acting as a feedback in response to temperature changes caused by human activity. Some sceptics however argue that it is the other way around … Continue reading
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
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
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.
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
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
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
