Will Cape Town Escape Its Water-Starved Fate?

I am sure by now many of you are aware of the major water crisis facing Cape Town, South Africa, as a result of dwindling water levels in their reservoirs and an increase in water demand. The article below by Lucas Joel, provides further details on the issue.

Monitoring for Water Quality on Farms, Reserves and Urban Creeks

This article published by David C. Richardson on July 29th 2017, as part of the Forester Daily News, highlights water quality monitoring in Millstone Watershed, waterways in Georgia and other locations throughout the United States.

Monitoring for Water Quality on Farms, Reserves and Urban Creeks

It has often been said that without water there would be no life. However, the presence of water is only one factor in the equation. It is not water alone that guarantees the presence of life; to sustain life the condition of that water must fall within a very specific range. Although life can be resilient—in the sense that for virtually any condition that can be imagined, some type of organism will thrive there—many forms of life are very sensitive, occupying one particular, narrowly bounded niche. Many of the specific organisms upon which society relies as part of the food chain or to sustain the habitability of the planet have a particularly narrow and specialized range of conditions under which they can thrive and propagate. Minor changes in salinity or temperature, for example, can drive fish like trout or salmon from a stream. And human activity can play a dramatic role in affecting these conditions.

Responding to Climate Change Deniers with Simple Facts and Logic

With many persons insisting that climate change is not actually taking place, (I’m hoping none of our staff are included in that group, but if you are this article is for you too) this article digitally published by Dork Sahagian on 30 March, 2017, provides five questions and answers that can be used to change the minds of those “climate contrarians” (Sahagian, 2017).

Global Significance of the Changing Freshwater Carbon Cycle – EOS

By Bopaiah A. Biddanda

Freshwater ecosystems constitute a small fraction of our planet but play a disproportionately large and critical role in the global carbon cycle.

As human activities continue to pump carbon into the atmosphere, the backbone of our understanding of the resulting warming is our knowledge of where that carbon is going: into the atmosphere, into the land, and into bodies of water. When it comes to accounting for the carbon absorbed and emitted by water, the role of inland freshwater may appear quite small compared to the vastness of Earth’s oceans. After all, inland lakes, rivers, streams, reservoirs, wetlands, and estuaries cover less than 4% of Earth’s surface [Downing, 2010; Verpoorter et al., 2014].But recent research shows that the roughly 200 million bodies of inland water play a much larger role in the global carbon cycle than their small footprint suggests. Inland streams and rivers move vast amounts of carbon from the land to the ocean, acting as carbon’s busy transit system.

They also play a disproportionately large role in the global carbon cycle through their high rates of carbon respiration and sequestration [Cole et al., 2007; Tranvik et al., 2009].According to recent estimates, the amount of carbon that inland waters emit is comparable to the net amount of carbon absorbed by living organisms on Earth’s land surface and in its oceans. Moreover, bodies of freshwater bury more carbon in sediments each year than the vast ocean floor [Battin et al., 2009; Aufdenkampe et al., 2011].

Nevertheless, there is great uncertainty in these figures, and scant data exist on continental and global scales. The changing climate is putting freshwater ecosystems at great risk: They are warming at an alarming rate, outpacing warming of the atmosphere and oceans. It’s crucial that scientists dedicate more resources to understanding the global impact of the freshwater continuum on the carbon cycle.

Caribbean Climate Outlook

Well folks I have been provided with the Caribbean Regional Climate Outlook Forum newsletter for January to June 2016, which provides both an overview of the climate outlook for January to June 2016, as well as, a look back on the climate impacts felt from September – November 2015.

I hope that many of you take the opportunity to view the outlook and encourage those around you to conserve water and practice water saving methods since Trinidad is expected to experience below to normal rainfall during this period.

When the Rastaman Speaks: Climate Change and Food Security

caribbeanclimate

Dizzanne Billy, 24, is President of theCaribbean Youth Environment Network (CYEN) inTrinidad and Tobago, where she works in the areas of education and public awareness on a number of environment and development issues. She is a climate tracker withAdopt-A-Negotiator and a young advocate for climate change action.

“Rastaman ah (is) the usual suspect.”– Prophet Benjamin

Discrimination is not uncommon in the Caribbean. But Carus John-Bejai is breaking the mold. At 23, this rastaman is flying through a PhD at the University of Nottingham, hoping to shed critical insight for Trinidad’s farmers in a changing climate.

Carus has always been intrigued by plants. Following the support from his parents, he began to see his love for plants as a way of “improving the living standards of not only those who rely directly on the sector but of the global population as a whole.”

Rainfall and Temperature Outlook for Trinidad and Tobago

Have you been wondering why it’s so warm during the night for the past few weeks or so? Well, wonder no more. According to the Met Office’s Rainfall and Temperature Outlook for Trinidad and Tobago, this has been a result of wetter than average rainfall being favored and more clouds being present which allows heat to be trapped near the ground during the night.

I always knew that when rain fell, the atmosphere would be more humid but I really didn’t think about it affecting night time temperatures though.

For those of you wishing to view the “Rainfall and Temperature Outlook for Trinidad and Tobago” issued May 25 2015 by the Meteorological Organization of Trinidad and Tobago, if you haven’t already, to get an idea of the impacts, responses and likely outcomes you can view it by clicking the following link Rainfall and Temperature Outlook for Trinidad and Tobago.

I do hope that the outlook enlightens you as it has me and assists you in keeping informed about such matters.
