During the process of photosynthesis, trees naturally absorb carbon dioxide from the atmosphere. Rainforests act as important 'carbon sinks' stemming global heating.
that. the intensity and speed and severity of climate change is, should be frightening to everybody when you connect the dots and make the observations that the media is making for us. so thanks for that. absolutely. and even more troubling, what we are seeing now, this is just the tip of the iceberg, right? it is. unfortunately we are in this disaster throughout the century, throughout the entire 21st century we are going to be dealing with this. and, here we are in 2020, two things are going to get much worse over the next 20 to 30 years before, even if you do everything right, that is not a foregone conclusion. but even if we do everything right, co2 concentrations in the atmosphere will continue to rise from 4:20, maybe 4:50 parts per million by mid century. then, start to decline, temperature will lacked behind
andrew leaky from his home country of scotland to the university of illinois. this is why i moved here actually. but the climate is changing this most fundamental way of life as well. it s what louis ziska has been sounding the alarm about. the carbon in the air is now changing the food coming from the ground. so we are essentially going into your time machine, as you say? absolutely. you ve stepped from 2019 into the mid century in terms of co2 concentrations. within this outlined space, these plants are getting gassed with 25% more carbon dioxide. why? that s the level scientists project our atmosphere will have in the year 2050. i just heard that the hissing sound. we re now on the upwind side of the plot. if you reach out, you can probably feel some of the co2 coming out the backside of the
