Global Average Temperature vs Temperature Extremes

In his March 2017 talk “The Brutal Logic of Climate Change”, at the University of Sheffield, Aaron Thierry outlined many of the aspects of climate change. This video here is the excerpt on temperature anomalies. Watch the full lecture at https://www.youtube.com/watch?v=r7TL_BbAd-s The emissions pledge pathway negotiated at the Paris conference has a probability of over…

Climate Data Mysteries, Wonders, and Reality (April 2017)

Dan Lunt: Past climates and climate sensitivity #DeepTime #Reconstruction #3DEdition

To curiosity-driven scientist Dan Lunt, understanding the past climate of our Earth (from the scorching greenhouse of the mid-Cretaceous, to the frozen wastes of the last ice age) is of fundamental interest.

Global temperatures are unstable because of increased greenhouse gases

A study by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, and Duke University in Durham, North Carolina, shows, in detail, the reason why global temperatures remain stable in the long run unless they are pushed by outside forces, such as increased greenhouse gases due to human impacts.

A potential future world scenario, driven by rapid regional changes

As someone who follows the climate topic for several years, I’ve to conclude that we are still far away from taking climate change seriously. Around 10 years ago there were rather minor groups of concerned scientists and bloggers, while the media was giving “a balanced view” to the so called deniersphere. This went on for…

Why is the Weather in the Northern Hemisphere so unusual mild? #JetStream #ElNino #PolarVortex

Here we look at the current weather configuration in the Northern Hemisphere, with the scope on the mild 2015 winter weather in what seems to affect many regions in northern latitudes this winter. The atmosphere in many northern regions like Canada (Northern America) or Europe is currently dominated by westerly jet stream winds. This configuration has…

NASA, NOAA Find 2014 Warmest Year in Modern Record

The year 2014 ranks as Earth’s warmest since 1880, according to two separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA) scientists. The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000. This trend continues a long-term warming of the planet, according to an analysis…

NASA | 2014 Warmest Year On Record

The year 2014 now ranks as the warmest on record since 1880, according to an analysis by NASA scientists. Nine of the 10 warmest years since modern records began have now occurred since 2000, according to a global temperature analysis by scientists at NASA’s Goddard Institute for Space Studies in New York. 2014’s record-breaking warmth…

Exceptionally mild temperatures in large parts of Europe and stormy UK weather with 100mph winds

2015 takes off with temperatures for parts of Europe hovering around 17C. And The Guardian warned of 100mph gale-force winds and snow to batter the UK. Temperatures in Germany spring like with meteorologists forecasting 17C in Germany Salzburg or in Wien Austria, for tomorrow the 10th of January 2015. Ironically, the ski resort Allgäu tries to…

New mechanism uncovered, causing potentially rapid Antarctic Glacier melt

An Australian-led research team found that sea levels may rise much faster than previously predicted by models, because changes by disruptive westerly winds, weren’t taken into account. Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase. Related Each degree of global warming might ultimately raise…

With further Arctic Amplification, How fast will Greenhouse Gas emissions accelerate in the Arctic Circle?

Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere.       CH4 Release The following studies explore the release of CH4 emissions in the Arctic region. OBSERVATION…

2013 was the second-hottest year without an El Niño since before 1850

The Guardian: According to the global surface temperate data set compiled by Kevin Cowtan and Robert Way, which achieves the best coverage of the rapidly-warming Arctic by filling in data gaps between temperature stations using a statistical method called kriging, 2013 was the 5th-hottest year on record (since 1850). The top three hottest years (2010, 2005,…

If There’s Global Warming … Why Is It So Cold?

It’s that time of year, the perennial “It’s snowing so it can’t be warming” season – or, as scientists call it, “winter”. Depends on where you’re standing, actually — I stood on a frozen lake with Dr. Jeff Masters to discuss the current planetary changes, but at the same time, in Alaska, historic warm temperatures…

2013 Is the Fourth Hottest Year on Record

By Phil Plait (Slate):  It’s official: 2013 is the fourth hottest year since records started being kept in 1880. It ties with 2003 for that dubious honor. This result was just announced by the National Oceanic and Atmospheric Administration. It uses global annual land and sea surface temperatures to make the call, and in 2013 these two measures combined…
