Newspaper Reports in Romania – What Do They Tell Us about Extreme Meteorological Events of the Early 19th Century?

Sources of information

Extreme meteorological events, such as droughts or floods, are expected to increase in many parts of the globe under predicted climate changes of the next decades (Fig. 1). Yet, the forecasted frequency, intensity and occurrence of extreme meteorological events include large uncertainties as they depend upon location and season. These events are of particular interest for society as they can cause important human, economic and environmental losses.





To better understand extreme meteorological events and to improve future meteorological forecasts, we rely on information extracted from natural archives such as tree rings, peat bogs, lakes and fluvial deposits (associated with rivers and streams). Natural archives provide information over hundreds and thousands of years back in time and are complemented by historical and instrumental data in the more recent past spanning few centuries. 


Historical data include chronicles, monastery documents, ship log…

Science Policy: An Approach to 'Actually Do Something' about Climate Change

by Heather Plumpton

What inspired you to apply to work on your PhD topic or current post-doc?

For me - brace yourself for a strong dose of naivety here - I wanted to do something about climate change. I wanted to make a difference, to have a positive impact on the world, to help tackle a big problem for humanity. I know that this isn’t the case for every researcher, and the importance of fundamental research should not be understated or swept aside in favour of more applied science. But there does seem to be a strong contingent of early-career researchers who went into research in the hopes of providing solutions and influencing the actions of governments.




After the initial burst of excitement about the potential application of my PhD research, I soon realised that achieving this positive impact on society was not as straightforward as I had imagined. I couldn’t just publish papers and attend conferences and hope that my research would be picked up and used by policy makers. So what s…

The Power of Networking as an ECR

I consider myself socially awkward; an introvert if you will. I best relate to the fictional character Tina Belcher from Bob’s Burgers; walking through life in my own hilarious and charismatic way while simultaneously finding myself sweating at the idea of walking up to complete strangers at conferences or workshops and introducing myself. Yet, here I am writing about my personal experiences regarding the power of networking at conferences and workshops.




But before I begin, you may be asking yourself ‘how does Vachel (pronounced like Michelle, but with a ‘V’, not Rachel with a ‘V’) break past her self-induced mental barrier of her own social awkwardness?’ Humor, my friends, and lots of it! I use humor to break the ice in almost every situation; whether it be in presentations at big conferences, organizing workshops, or in social gatherings. Nothing sets the stage better than a quick laugh. Plus, it adds a bit of character and lets your audiences know that you’re pe…

Around Antarctica in Five Years

I’m currently working on a project in which I’m trying to reconstruct changes in the circulation patterns of the Southern Ocean and their impact on past climate parameters. However, while looking at my data, pondering how water masses are transported from one spot in the ocean to another, I suddenly had to think about a big yellow buoy which crossed my path last year…


Is it an AUV? Is it an Argo Float? No! It’s a renegade buoy, casually braving the Southern Ocean.

In February of 2017, heading for the Antarctic Amundsen Sea, we had been sailing the Southern Ocean for about a week. One day before we reached the sea ice margin, we spotted a big yellow buoy, dancing in the icy waves.


From the distance, the crew of R/V Polarstern could easily identify the buoy as the detached, uppermost part of a scientific mooring. During our expeditions, we always try to collect floating garbage and dispose of it properly, back on land. Therefore, the captain and our chie…

Dig Deeper! Why Do We Care about Lake Sediments?

Summer at the lake

Many people, when asked what they think about when they hear the word "lake", immediately answer "swimming", "summer" or "fish" (especially if the person asked is a fishing enthusiast). In this post, I will try to show you that lakes have even more to offer. To be more specific, I will explain why lake sediments in particular are of high interest to many people.




Why does all of this mud matter?

The answer to this question is quite complex. Lakes are considered as one of the best natural archives to track environmental and climatic changes because they store all information available not only from their direct catchment (Fig. 1) but also from a bigger area. It might come as a surprise to some, but climatic fluctuations, fires, human activities (eg. industry, agriculture) and many other factors can be tracked with the use of lake sediments.

The biggest advantage of lake sediments is that the life cycle of a lake is rel…

A Scenario for Sustainable Energy and Water Systems Integration in Urban Areas

by Renata Mikalauskiene

Reliability and quality of energy and water is a global concern that impacts the daily life of the 21st century civilization.
Water and energy are intricately linked and should be managed as interrelated resources. The concept of the energy and water nexus refers to the relationship between the water used for energy production including both electricity and sources of fuel and the energy consumed to extract, purify, deliver, treat and dispose of water or/and wastewater.

Rising demand for energy has the potential to significantly increase water consumption. Energy producers and consumers seek to evaluate their energy options and developing policies that apply appropriate financial carrots and sticks to various technologies to encourage sustainable energy production, including cost, carbon, and security considerations. Energy and water nexus needs to be part of this debate, particularly how communities will manage the trade-offs between water and energy at the loca…

Convening a Conference Session: A Recommendation Letter

Different people benefit from conferences in different ways, with varying success and comfort levels. 



You might love public speaking or you might feel nauseous from the very thought of walking up to the podium. You might ask yourself where on earth the advice originated from that you should picture the audience without clothes; a room full of naked colleagues with their eyes fixed on you would not necessarily make you feel any less uneasy.

You might love to mingle and engage in fruitful and inspiring discussions at poster sessions. You might find yourself face-to-face with a renowned scientist from your field, your first instinct being to ask them for an autograph (or a job), but after careful consideration you settle for feeling nervous and acting like a fool instead.
If you are like me, you might develop a whole new set of insecurities when standing next to your poster, trying to figure out how to attract readers and encourage conversations, but at the same tim…

A Short Story of the Struggle to Get Long Records of Air Temperature in Toruń, Central Poland

Image
by Aleksandra Pospieszyńska


My latest paper concerns climate changes during the instrumental measurements period (1871–2010) in Toruń, which is located in Central Poland (Europe).
The climate is constantly changing. Some of these changes can be noticed over the course of a human life. Other changes are visible only on longer time scales.

In this post, we will look closely at the changes observed during the period of instrumental measurements.

Why do we need the longest and the best quality of measurement series in studies on climate history?
Longer series of measurements allow us to determine how the climate changes with greater accuracy, and to calibrate models, both for the reconstruction of the climate in the past and its predictions for the future.

The minimum period that can be considered in climatological research is 30 years. If we look at the last 30 years, we are dealing with a remarkably rapid increase in air temperature. Conversely, if we take another period, for example 1940–197…
