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.

Ice sheet deglaciation and methane emissions, with the scope on Greenland’s melt season

On June 9 2016, Nuuk, the capital of Greenland, reached the warmest temperature ever recorded for the month of June anywhere on the island, 24 degrees Celsius (75 degrees Fahrenheit). An article from NSDIC, published June 22 elaborated on the broader situation: Surface melting on Greenland’s Ice Sheet proceeded at a brisk pace, with three…

Heat wave, air pollution, mortality, and adaptation, a quick look

While summer currently gears up, during exceptional continued record global warming, temperatures are set to reach the highest so far this summer in many parts of the northern hemisphere – within the next few day’s (Germany, U.S. etc). Here we look at the past 2003 heat wave and what attributed to excess deaths during that extensive heat period…

Ted Scambos on new Antarctic Ice Study insights

Ted Scambos, Lead Scientist at the National Snow and Ice Data Center, weighs in on the latest study showing increased vulnerability of the Antarctic ice sheet to collapse. Is it possible that the most recent study of ice instability in Antarctica is cracking the unstable cliff face of climate denial? (how’s that for a tortured…

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…

AGU 2015: Global impacts of the 2015 – 2016 El Niño

The unfolding 2015-16 El Niño event is already the strongest the world has seen since 1997-98, and people all over the world are feeling or are expected to feel its impact in a variety of ways. Scientists from NASA and NOAA will present findings on El Niño’s global reach as seen from the vantage point…

AGU 2015: The impacts of heat stress on densely populated regions in the 21st century

Globally, heat kills more people than any other weather-related event. With temperatures and humidity expected to increase in the coming decades, heat stress is projected to have increasingly severe impacts on many regions of the world. Here, researchers estimate the global exposure to fatal heat stress throughout the 21st century and its effects on human…

AGU 2015: Jennifer Francis recent studies on Weather Blocking Patterns

Recent Changes in Blocking Characteristics Assessed Using Self-Organizing Maps Speaker: Jennifer Ann Francis Blocking anticyclones are known to be associated with persistent weather patterns that often lead to extreme weather events. An outstanding question, however, is whether the frequency and/or intensity of these dynamical features are changing in response to human-caused climate change, and in…

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…

Climate change could suffocate life on planet Earth

EurekAlert (Release): Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to researchers from the University of Leicester. A study led by Sergei Petrovskii, Professor in Applied Mathematics from the University of Leicester’s Department of Mathematics, has shown that an increase in…

NASA: Earth potential to absorb Emissions is out of Balance

A Breathing Planet, Off Balance NASA:  Earth’s land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it’s uncertain whether the planet can keep this up in the future. NASA’s Earth science program works to improve our understanding of how carbon absorption and emission processes work…

NASA: Coolants Contribute to Ozone Depletion and are strong Greenhouse Gases

According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption. A class of widely used chemical coolants known as hydrofluorocarbons (HFC) contributes to ozone…
