‘No, climate sensitivity is not smaller, it is higher than we thought’ – because organic aerosol feedbacks mask warming

Says an international research group led by Gothenburg University. It serves to show individual climate sensitivity studies are never conclusive but add up bits of fresh understanding to an already enormous pile of data and knowledge.

World average land temperatures have risen by almost 1 degree since 1955 – says 4th consecutive study

Whom would you rather believe? The world’s three best-established atmospheric research institutes – or a Berkeley dream team with the current Physics Nobel Prize laureate, backed up by the largest collection of land temperature measurements ever? So sorry to confuse … Continue reading →

New evidence for bipolar seesaw link between Greenland and Antarctica – and abrupt climate variability

Glacials and interglacials on the northern and southern hemisphere somehow do not seem to correspond. This has led to a ‘thermal bipolar seesaw theory,’ whereby an off-mode in the thermohaline circulation leads to an ice age in Europe, but excess … Continue reading →

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 →

Ongoing paleo study may help tune CO2 climate sensitivity

Here on Bitsofscience.org we’ve discussed the Paleocene-Eocene Thermal Maximum (PETM) – that sudden CO2 and methane-induced peak climate warming (or ‘hyperthermal’) 55.8 million years ago of around 6 degrees over 20,000 years – on several occasions, because it offers an … Continue reading →

NOAA’s analysis of climate records 2010: trend consistent with climate change

Here on Bitsofscience.org we hope to be your climate records reference point, so we try not to miss any of the major reports on temperature trends or Arctic melting records. That means we definitely could not ignore yesterday’s release by … Continue reading →
