The heat of a warming planet, like an artist’s palette knife on a canvas, etches its way across Western forests, slowly altering ecosystems that have flourished for centuries. cited: Climate change is transforming Western forests. Mark Jaffe, The Colorado Sun July 25, 2019
- “As ecosystems change, there are going to be winners and losers,” said Thomas Veblen, a biogeographer and distinguished professor at the University of Colorado. “The regulator function of the forest could diminish … leading to more runoff and flash floods. With a reduction of the forest canopy, we are going to see the potential for greater erosion. The question is how much of the forest will fail to regenerate.”
Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a new study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems. cited: Climate change may cut soil’s ability to absorb water.

- … a study published in the journal Nature last year showing that regional increases in precipitation due to climate change may lead to less water infiltration, more runoff and erosion, and greater risk of flash flooding.
The Arctic Ocean could become ice-free in the summer in the next 20 years due to a natural, long-term warming phase in the tropical Pacific that adds to human-caused warming, according to a new study: cited: Ice-free Arctic summers could happen on earlier side of predictions. American Geophysical Union, Science Daily, February 27, 2019.
- There are different climate models used by researchers to predict when the first ice-free Arctic September will occur. Most models project there will fewer than 1 million square kilometers of sea ice around the middle of this century, but projections of when that will occur vary within 20-year windows due to natural climate fluctuations.
A global study has found a paradox: our water supplies are shrinking at the same time as climate change is generating more intense rain. And the culprit is the drying of soils, say researchers, pointing to a world where drought-like conditions will become the new normal, especially in regions that are already dry. cited: The long dry: Why the world’s water supply is shrinking.

- “It’s a double whammy,” said Sharma. “Less water is ending up where we can store it for later use. At the same time, more rain is overwhelming drainage infrastructure in towns and cities, leading to more urban flooding.”

Ive been following this theme very closely and becoming even more aware of our responsibility to hold governments, businesses and ourselves, as consumers, accountable for the actions we take to destroy or stop, mitigate and adapt to climate changes. As we learn that we reached the tipping point, we do need to unite as a race, to proactively do something about it.
The more I contemplate how to take responsibility for my own behaviors, I find this concern to be extremely complex.
