Coccolithophores — tiny calcifying plants that are part of the foundation of the marine food web — have been increasing in relative abundance in the North Atlantic over the last 45 years, as carbon input into ocean waters has increased. Their relative abundance has increased 10 times, or by an order of magnitude, during this […]

Wild weather swings from the phenomenon known as El Nino have rocked commodities and countries from Australia to Paraguay. Now, analysts are tipping renewed jitters spurred by La Nina, El Nino’s little sister. While El Nino is characterized by rising sea surface temperatures in the Pacific Ocean, La Nina represents periods of below-average temperatures, which […]

El Nino’s effect on global temperatures and weather systems has been dramatic in the past few months, achieving records for individual months and, with a significant contribution from the Pacific “Blob,” is bound to make 2015 globally the warmest year of the instrumental era. Many were expecting the current El Nino to start in 2014. […]

Arctic ice declined in the decade prior to 2007, but has not declined since. What we have seen in the last decade is a plateau in Arctic ice extent, analogous to the plateau in surface temperatures. This year end report shows there is no reason to worry about Arctic ice melting. Against the odds, 2015 […]

Global warming is happening at around 1.2C per century, according to the 37 year old satellite dataset maintained by the University of Alabama in Huntsville Global warming is within the 2oC goal set by the United Nations (UN), according to scientists from the University of Alabama in Huntsville (UAH). An analysis of satellite data stretching […]

A new paper forecasts that overall winter sea ice extent will remain steady in the near future. This research underlines the significance of satellite data showing that Arctic sea ice extent now is broadly similar to that reported a decade ago. Climate scientists at the US National Center for Atmospheric Research (NCAR) present evidence in […]

Way back in June, John Christy and I called 2015 as being the warmest year on record…in the surface thermometer data. Given the strong El Nino in progress, on top of the official thermometer data warming trend, this seemed pretty obvious. Of course, everyone has their opinions regarding how good the thermometer temperature trends are, […]

The hiatus in annual average surface temperature does not exist and never has and is a myth created by climate sceptics. That’s what a new paper claims. What’s more its very description as a “hiatus” or a “pause” is dangerous because it misleads both scientists and the public. The paper in question is published in […]
