Impacts of a warming Europe

The European continent has a very rich culture and unique landscapes and climate. The climate is driven by the Gulf Stream, which makes it milder and wetter in comparison to other regions at similar latitudes. Everyone, who has traveled through Europe knows that landscape and culture change greatly even over small distances. Climate change is likely to impact the economies of European countries, both in positive and negative ways. How will warming affect tourism in summer and winter? Will some of the warming reduce demand for electricity?

Tornadoes in the United States are increasing in power

Tornadoes are the most violent of atmospheric storms with wind speeds exceeding 120 m/s. A tornado consists of a rotating column of air reaching from a thunderstorm cloud all the way to the ground. When a tornado develops a condensation funnel of water droplets and debris it becomes visible to the human eye like in the photo below. As opposed to hurricanes, tornadoes are occurring on a much smaller scale with shorter lifetimes and travel distances. Yet, they can be very destructive.

Green GB Week

The Intergovernmental Panel on Climate Change (IPCC) opened a meeting on October 1st 2018 in Incheon, South Korea to discuss the Special Report on Global Warming of 1.5°C. Governments requested a report from the IPCC on the effects warming by 1.5°C would have in order to help them address climate change. 195 IPCC members governments and IPCC scientists will meet this week to finalise the Summary for Policymakers of the report.

Unprecedented weakening of North Atlantic circulation theWeather Club Fri, 13/04/2018 - 10:36

The warm, saline waters of the Gulf Stream meander northeasterly across the Atlantic Ocean, eventually forming the North Atlantic Current.  During winter, these salty waters cool and descend – it is this deep convection that is a key part of the Atlantic meridional overturning circulation (AMOC), the ocean conveyor belt. This conveyor belt is essential for heat exchange between the ocean and the atmosphere - it releases heat into the atmosphere above the North Atlantic Ocean then travels through the ocean, resurfacing in other areas of the world.

Climate change to increase clear-air turbulence threefold

Climate change is not just occurring at ground level, but also high up in the atmosphere – and it will have significant impacts on air travel. One of the ways in which it can impact air travel is by increasing the strength and incidence of clean-air turbulence (CAT), one of the leading causes of weather-related aviation incidents.  

Drizzle riddle solved

A recent study by NASA scientists at the Jet Propulsion Laboratory in California and University of Toronto indicates that updrafts are more important than previously thought in determining whether clouds produce drizzle rather than larger-sized raindrops. Such findings will help improve the accuracy of model predictions of rainfall, a challenge for both short-term weather forecasting and longer-term climate projections.

Extreme storms triple in Sahel due to Global Warming theWeather Club Mon, 21/08/2017 - 15:41

Over the past 35 years extreme storms in the Sahel have tripled and it’s down to global warming, according to research conducted by NERC scientists at the Centre for Ecology and Hydrology. In such storms, clouds can grow to heights of 16 km and can produce substantial volumes of rainfall. Indeed, in 2009 one downpour deposited 263 mm of rainfall in several hours and forced 150,000 residents of Burkina Faso to leave their homes.
