Climate Impacts Happening Now: Westward (?) Migration of Forests

By Central Texas, Drought, Extreme Weather, forest health, Forest Mortality, Impacts, rainfall, Shifting Ecology, short-term, The Unexpected, Vegetation Response

A recent article in Atlantic implies climate change to be wrongly viewed as something we don’t yet know much about. This article “American Trees Are Moving West, and No One Knows Why”, is half correct. The authors in the study reported upon reveal the reasons why trees are shifting west (as well as north), and…

President Trump it seems, has given us permission to backslide with our thinking about climate change. Until we have rule or law that tells us we must do something about climate pollution, “those that would rather it not be real” have won. This allows the debate to rage encouraging doubt. The Clean Power Plan and…

Climate Predictions Come True: Extreme Rainfall

By Deniers and Delayers, Extreme Weather, Impacts, rainfall, Temperature

In 1834 and 1850, two European scientists (Clausius and Clapeyron) developed scientific principles that told us that warmer air holds more water. In the 1960s and 70s the computer models that first simulated our climate showed that more atmospheric CO2 would increase Earth’s temperature, relative humidity, and total precipitation because of the Clausius–Clapeyron principles. In the…

We Can Have a Healthy Climate With Zero Warming in Our Lifetimes, by Bruce Melton

By Abrupt changes, Drought, forest health, Forest Mortality, Impacts, in-depth and Popular Press, pine beetle, Shifting Ecology, Truthout.org

  We can have a healthy climate — a climate with zero warming — in our lifetimes. The message for the last 20 years has been that we have to reduce emissions drastically to prevent dangerous climate change of more than 2 degrees C (3.6 F). This strategy would have likely worked when it was…

Rain Bombs: Increasing Precipitation Extremes

By Central Texas, Extreme Weather, flood, Impacts, rainfall

Increasing extreme storms are a big deal. Our civil infrastructure design is based on our old climate. Meteorologist across the country have been evaluating the historic record to see exactly how much change has already taken place. Climate modeling is still advancing towards being able to robustly understand exactly how much the most extreme storms will increase in the…

The Beetles: 6,000 Miles of Climate Change — Long Version

By Abrupt changes, Drought, forest health, Forest Mortality, Impacts, pine beetle, Shifting Ecology, Vegetation Response

This is the original long version with much more detail and all of the destinations and forest health descriptions along the 6,000 mile route. The abbreviated  2,000 word version was published on Truthout on February 16, 2016 is here. We were awash for 19 days in a tumultuous sea of mountains and forests, drifting a course through the heart…

More on the Shutdown of the Gulf Stream

By Abrupt changes, Greenland, Gulf Stream, ice sheet, ice sheets, Impacts, Oceans

Dansgaard Oeschger climate variability, more easily remembered as abrupt climate change, has been known from across the world through numerous lines of investigation since the early 1990s. This research greatly increases the robustness of the theory that a freshwater cap in the far North Atlantic from melting ice plays a significant role in abrupt change….

Temperature Changes: It’s Not All About the Average Global Temperature

By Extreme Weather, Forest Mortality, Impacts, pine beetle, Temperature

Earth has warmed about 0.9 degrees C on average and the Arctic on average has warmed two to three times as much as the average. Daily temperature variation and annual temperature variation make a difference. Climate scientists have been warming us for over a generation that climate change would mean greater insect infestations on a…

Early Spring Drives Butterfly Decline

By Impacts

Reposted from NSF Press Release: http://www.nsf.gov/news/news_summ.jsp?cntn_id=123520&org=NSF&from=home Early snowmelt caused by climate change in the Colorado Rocky Mountains snowballs into two chains of events: a decrease in the number of flowers, which, in turn, decreases available nectar. The result is decline in a population of the Mormon Fritillary butterfly, Speyeria mormonia. Using long-term data on date…

Thoreau’s Woodland Is No More

By Impacts

March 21, 2012: — Henry David Thoreau, Concord Massechusetts, Walden Pond. Among temperature and non temperature dependent flowering species, climate change has affected and will likely continue to shape the pattern of species loss in Thoreau’s woods. Species that have decreased greatly in abundance include anemones, buttercups, asters, campanulas, bluets, bladderworts, dogwoods, lilies, mints, orchids,…

Welcome to Climate Change Texas Part 1: What Can Be Done About Climate Change in Texas?

By Abrupt changes, Agriculture, alternatives, Austin, Central Texas, Climate Catastrophes, Deniers and Delayers, Drought, forest health, Forest Mortality, Impacts, in-depth and Popular Press, rainfall, Solutions

As I have been saying in the first two installments of this series, climate change is already much more extreme than most scientists have been predicting. This is mainly because the majority of predictions are based on the “most likely” emissions scenario and because we have not reduced our emissions like climate scientists told us…

The Blob Could Have Devastated Global Ecologies the Last Time Climate Changed Anywhere Near as Fast as it is Changing Today

By Impacts

This one is stranger than strange. scientists have long been puzzled by what looked like fungal bodies that seem to cover many fossils of different kinds from what is called the end-Permian. This “end-Permian” is how the end of the Permian Epoch is described. It’s also called Permian Triassic Extinction 251 million years ago when…

An article in Nature News, in the journal Nature, describes the prediction of this famine and it linked to climate change. Last summer, the Famine Early Warning System Network (FEWS NET) set up by the US Agency for International Development to help policy makers prevent humanitarian disasters, predicted this major and growing famine.

Non CO2 Greenhouse Gas Warming Will Persist for Longer Than 1,000 Years

By Impacts

Non CO2 Greenhouse Gas Warming Will Persist for Longer Than 1,000 Years  Abstract: Emissions of a broad range of greenhouse gases of varying lifetimes contribute to global climate change. Carbon dioxide displays exceptional persistence that renders its warming nearly irreversible for more than 1,000 years. Here we show that the warming due to non-CO2 greenhouse…
