The unknown costs with afforestation

The March episode of the Bjerknes centre podcast is about afforestation. There are several benefits related both to climate and to wildlife by planting forest and especially letting forest reclaim the landscape, but there are hidden costs. One example is the afforestation project i China were they have over 30 years planted an area on the size of Belgium. In this project they have discovered that the trees are using much more water than the landscape it replaced, so there are problems with the water level downstream. Another example is how the forest alters the albedo of the high latitudes in the northern hemisphere.

Priscilla Mooney, a NORCE researcher and a member of the Bjerknes centre got interviewed by Stephen Outten and me. As normal it is Stephen that bears the brunt of our side.

The conclusion is that the best we can do is to leave the current forests as they are and be very careful in helping the forests reclaim the area that we have stolen from them the last 100 or more years.

Einar Ólason om neXtSIM – The next generation of ice forecast

Jeg har glemt å poste denne, en podcast med Einar Ólason og Stephen Outten om neXtSIM, den neste generasjons ismodell. Denne skal hjelpe oss med å forutsi hva som skjer med de store isdekkene, ikke minst i Arktis.

Are we melting Antarctica irreversibly?

The great ice-sheets in Antarctica and Greenland holds many mysteries. David Chandler, a postdoctoral fellow at the Bjerknes Centre and NORCE, are trying together with his colleagues to unravel these mysteries. In this episode David Chandler takes Stephen Outten and Ingjald Pilskog to the Antarctica where we are discussing how global warming are melting the ice-sheet, in some places irreversibly, leading to sea level rise and life altering climate changes to people all over the globe.

David Chandler is a postdoctoral fellow at NORCE and Bjerknes Centre for Climate Research.

Stephen Outten is a researcher at Nansen Environmental and Remote Sensing Center and Bjerknes Centre for Climate Research.

Ingjald Pilskog is an associated professor at Western Norway University of Applied Sciences and connected to the Bjerknes Centre for Climate Research.

Blir klimaet bedre om vi snakker norsk?

Språkforsker Kjersti Fløttum og klimaforsker Lea Svendsen diskuterer språkets betydning for klimadebatten og vår forståelse av verden. Kjersti Fløttum er professor ved Institutt for fremmedspråk ved UiB og leder av LINGCLIM, mens Lea Svendsen er postdoktor ved Bjerknessenteret og Geofysisk institutt ved UiB.

Programleder er Ellen Viste, rådgiver ved Bjerknessenteret for klimaforskning. Hun jobber med formidling i senteret og har bakgrunn som forsker med nedbør som spesialfelt.

Episoden er tatt opp hos UiB i Media City Bergen.

Den er redigert av Ingjald Pilskog, førsteamanuensis i naturfag ved lærerutdanningen ved Høgskulen på Vestlandet og formidler ved Bjerknessenteret for klimaforskning.
