The International Day of Trees

Maybe you have heard about the international Day of Water or Day of Happiness or Day of Friendship?! There is also a Day of Trees! There is a World Tree Day, an international Day of Forests and an Arbor Day.
Whereas the date of the Arbor Day can be defined by every country itself and was suggested by the United Nations in 1951, the German Tree Day is the 25th of April. It was first celebrated in 1952. Federal President Theodor Heuss and the President of the German Forest Protection Association, Federal Minister Robert Lehr, planted a maple tree in Bonn’s court garden (Bonner Hofgarten). Since then the Day of the Tree is celebrated every year in April. The idea behind the Day of the Tree is to remind us of the importance forests have for the people and the economy.
The children of Plant-for-the-Planet have pledged the goal to plant 1,000 Billion new trees by 2020 and since 2007 they have been taking over the responsibility together. They organize planting parties where they plant tree together and collect promises and plans to plant new trees by other people. Download our step-by-step guide and find out how best to plan your planting.
You can register your planted tree to contribute to the tree counter. It is very important that every single tree is registered, as it is the only way to know how many trees are missing to reach the 1,000 Billion goal!

Arctic calling Augsburg

Last night the major of Augsburg Dr. Gribl and the two Plant-for-the-Planet ambassadors for climate justice, Clara and Alexandra, got a phone call live from the Arctic.
In the presence of local media Bernice reported to them the daily challenges on the ice; dragging the heavy sleds, fighting the freezing temperatures and walking against strong winds. Two ski sticks already broke, because of the extreme cold. With these conditions the three adventurers are only covering 15 km distance per day. “It’s exhausting but we will make it!” is the message she is sending to everyone, also in the wider context of fighting the climate crisis.

Dr. Gribl was proud to report to Bernice what the people of Augsburg are achieving while the three polar adventurers are continuing with the expedition.
Students, teachers, work colleagues, friends and whole families are planting 15.000 trees. Since last week, more than 500 people have already participated, planting almost 5.000 new trees so far and helping to reforest an area, which has been destroyed by a hailstorm last summer.

As you might know; Plant-for-the-Planet’s goal is to plant 1.000 billion trees till 2020 because that’s the amount we still have enough space for in the world. This means every global citizen has to plant 150 trees each! If everybody plants 150 trees, these will absorb one fourth of the human-made CO₂ -emission.

Augsburg is the kick-off event and prototype for all global tree-planting actions to come. Thereby, the major takes over the patronage and promises to plant one tree for every citizen. The remaining 149 trees can be donated by the citizens and regional companies themselves.
Plant-for-the-Planet is planting trees on our own forest area in the state of Campeche, Mexico. There, trees grow faster and help even faster against the climate crisis. In 10 years, these currently still clear-cut grounds will be planted densely with trees that will bind 100.000 tons of CO₂ every year. Our plan is to sell the timber as furniture wood and thus save carbon for many decades. If we then plant new trees right away, we can save new CO₂. We plant upscale hardwood such as Mahogany as a way to store CO₂ on a long-term basis.

Share this idea with your major and make your city follow the example of Augsburg!


Mayors get involved

Get the mayor of your city involved and help us reach our goal of planting 1.000 billion trees all over the world. This means in effect an amount of 150 trees per citizen which could bind one quarter of the carbon dioxide emissions we emit. Ask your mayor to plant 150 trees for every citizen of your city! Is there not enough room in your area to plant such a vast amount of trees at the same time? Well, ask him to plant trees where there is more space and go South! That is also advantageous for the local population who can make profit from the trees we plant by selling the wood and also, trees can grow four times faster in those areas like Africa, Asia or South America as a result of the favorable environmental conditions.
Follow the example of Clara and Alexandra from Augsburg who cooperated with the mayor of their city, their forest administration as well as with local companies to get an annual tree pledge, have planting parties and plant trees in many different continents.
In doing so, it does not matter how many pledges you get, every planted tree will help us create a greener future!

What is the Albedo?

A scientific term which has become more present and important in the last years when talking about the Arctic is ‘Albedo’. But what does it mean? You know how your parents tell you to wear white T-shirts when it is sunny outside because with a black T-shirt you feel way too hot!? That’s actually what is behind word Albedo.
Albedo has its origin in the Latin language meaning ‘whiteness’ because it explains the level of light reflection of a surface. It is always expressed as a number between 0 and 1. 0 stands for 0% reflection and 1 for 100% reflection. So, surfaces which reflect less sunlight for example will have a smaller number whereas surfaces which reflect a lot light will have a higher Albedo value. It means that dark surfaces as dark blue ocean water or your black T-shirt absorb that sunlight – they keep the light and warmth. That is also an explanation for why it would get too hot in that black T-shirt on a sunny day. However, bright surfaces like snow, ice, white clouds and also the white T-shirt have a higher Albedo number because they reflect the light. It means that the sunlight which is coming down to earth is again going back into the atmosphere – it is being reflected. The picture at the bottom shows how the Albedo effect works. You can already start wondering what that means for the Arctic. Which impact the Albedo effect has on the global climate you will learn here tomorrow!
