Could Spruce Forests Offset Global Warming?

Researchers from the University of Lund in Sweden,  are measuring terpene particles emitted by spruce/fir forests, which are believed to have a cooling effect on the climate. They believe that planting more of this type of forest could help offset global warmingPlanting spruce forests could increase the carbon uptake. They would release aerosol particles which have a cooling effect on the earth.

We saw that in the 1990s there was a big eruption of a volcano called Mount Pinatubo. It released an enormous amount of atmospheric particles into the air. Then the global climate was cooled for two years. And that’s how the atmospheric particles are acting on the climate. That’s one example of how the terpenes can cool the climate via atmospheric particles,” says Adam Kristensson, Nuclear physicist at the Lund University. Various of air samples  are being tested through solution reacting with carbon to find out if carbon comes from natural sources or fossil fuel burning.

Climate Change: How To Forecast Changes In Weather More Accurately

Europe is launching  a satellite this week that will use new laser technology to measure the winds sweeping across Earth and help scientists forecast changes in weather more accurately.

The Aeolus mission will provide scientists with data on winds in remote areas, such as over oceans, that they have not been able to get from weather balloons, ground stations and airplanes but which are crucial to predicting changes in weather.

Forecasting is of course still limited, but then we will certainly be able to understand the processes better that lead to extreme weather phenomena,” Paolo Ferri, the European Space Agency’s (ESA) head of mission operations, told  ahead of the launch.

Many scientists warn that global warming will result in more frequent and intense heatwaves, precipitation and storms, causing billions of euros in damage and costing thousands of human lives every year.

Better weather forecasts will allow scientists to warn the population when hurricanes are heading their way and predict weather patterns such as El Niño, which can cause crop damage, fires and flash floods.

The Aeolus mission – named after a character of Greek mythology who was appointed keeper of the winds – is scheduled to blast off from Europe’s space port in Kourou, French Guiana
