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…

Worldwide Extreme Floods (Sep-December 2015 – Japan/Brazil/India/UK/USA South Florida)

Footage of recent flooding in Japan, India, Brazil, UK (Northern England / Wales / Scotland / Cumbria), Florida United States. There have been more floods, i.e. in Portugal, Singapore, and other parts of the world, and it is projected to get worse with increased temperatures due to global warming. New York Times: A 2015 study…

Doubling times of 10, 20 or 40 years yield sea level rise of several meters

According to a new study, sea level rise of several meters might happen faster then previously thought. Based on data from past climate changes, when sea level rose to +5–9 m, including the occurrence of extreme storms – during a time when temperatures were less than 1 ◦C warmer than today, experts warn of similar…

The dangerous silence on climate change and extreme weather

We know that CO2 emissions are bad for climate and subsequently the weather. We know that we have to do something about it, because if not things will turn really ugly with large scale carbon releases (i.e. permafrost melt). However, the current projected changes are bad for many, and because of irreversible changes. So why then is…

We need to really begin the phase out of CO2 emissions

Think of climate change as a cancer. Your doctor told you that he spotted what appears to be likely a melanoma skin cancer, but he is not 100% sure. Do you wait till the signs become more apparent? The cancer might spread in your body, by that diminishing the chance for survival, or do you ask the…

Epic flooding in Texas, during El Nino year and locked Jet Stream configuration

Tornadoes, flooding, and stormy weather currently affects large parts of central Texas. There is also live coverage, for example IBT, The WeatherChannel, or AccuWeather. The situation is still developing, because of possible dam breaches, downed power lines and trees, and black outs. Further precipitation is likely at the end of the week. Governor Greg Abbott called the deadly flooding…

Over 500 dead across India as heat wave sets in, Telangana’s Khammam sizzles at 48 degrees

Allahabad was the second hottest at 47.7°C, six degrees above normal; Nandigama in…

The impacts of sea level rise on nuclear power plants

United States During the 1970s and 1980s, when many nuclear reactors were first built, most operators estimated that seas would rise at a slow, constant rate.  During Superstorm Sandy waves came close to reaching the Salem 1 nuclear reactor at Lower Alloways Creek, New Jersey. While it’s not clear how many current plants will still…

A world with this much CO²: lessons from 4 million years ago

With Dr Chris Brierley, UCL Geography In Spring last year, carbon dioxide concentrations passed 400 parts per million in the atmosphere — a level not seen since the Pliocene era (3-5 million years ago), and perhaps not even then. We know that the Pliocene was a warm world without glacial cycles, and that the climate…
