Day 15
SWBAT:
-Define conservation and make a personal connection
-Define natural resources and make a personal connection
-prepare to discuss how the ocean, our most important natural resource is
influenced by human activity, and what could that mean to the future of life as we
know it (Monday)
W-UPS-
humans have an interesting ability to ignore things that area not in their daily routine or personal bubble.
1. What is N.I.M.B.Y.? Defend or destroy the concept.
2. out of sight out of mind (apply it to defend or destroy the concept)
Part of being a good environmental citizen of this world means being aware of
current events and news. We will frequently consult news articles either because I
provide them or you choose your own.
Choose an article and read it, take notes on it and make a miniposter- with a title,
illustration, brief description, 5 bulletized facts and a personal connection.
Due date window today through 9am Monday morning
(take a photo and turn in to canvas),
Monday: we will do three peer reviews and present them.
Ocean’s wildlife populations down by half
Earth's oceans show decline in microscopic plant life
Date: September 17, 2015
Source: World Wildlife Fund
Summary: A new report reveals an alarming decline in marine biodiversity over the
last few decades. According to the report, populations of marine vertebrates have
declined by 49% between 1970 and 2012, with some fish species declining by
almost 75%.
Date: September 23, 2015
Source: NASA/Goddard Space Flight Center
Summary: The world's oceans have seen significant declines in certain types of
microscopic plant-life at the base of the marine food chain, according to a new
NASA study. The research is the first to look at global, long-term phytoplankton
community trends based on a model driven by NASA satellite data.

Embrace the chaos: Predictable ecosystems may be more fragile

Summary: Tiny zooplankton animals, each no bigger than a grain of rice, may be
playing a huge part in regulating climate change, research has found.

Summary: Managing our environment for predictable outcomes is risky, say
researchers. In fact, more often than not, it backfires, they say.

A more acidic ocean will bend the mermaid's wineglass
Melting Arctic sea ice accelerates methane emissions
Date: September 15, 2015
Source: University of Washington
Summary: New research shows that a more acidic ocean can weaken the protective
shell of a delicate alga. The findings come at a time when global climate change may
increase ocean acidification.

Summary:Methane emissions from Arctic tundra increase when sea ice melts,
according to a new study. This connection has been suspected before, but has
lacked strong evidence until now.

Global warming can alter shape of the planet, as melting glaciers erode the land
Fish getting smaller as the oceans warm

Summary: Climate change is causing more than just warmer oceans and erratic
weather. According to scientists, it also has the capacity to alter the shape of the
planet.

Reforestation's cooling influence is a result of farmers' past choices
Date: September 30, 2012
Source: University of British Columbia
Summary: Changes in ocean and climate systems could lead to smaller fish,
according to a new study.
http://www.sciencedaily.com/releases/2012/09/120930142058.htm
Date: July 26, 2011
Source: Carnegie Institution
Summary: Decisions by farmers to plant on productive land with little snow
enhances the potential for reforestation to counteract global warming, concludes
new research. Previous research has led scientists and politicians to believe that
regrowing forests on Northern lands that were cleared in order to grow crops
would not decrease global warming. But these studies did not consider the
importance of the choices made by farmers in the historical past.
Unexpected interaction between ocean currents and bacteria may weaken
ocean's ability to absorb carbon dioxide
Date: September 13, 2013
Source: University of Southern Denmark
Summary: For the first time, researchers have successfully demonstrated an
interaction between ocean currents and bacteria: The unexpected interaction
leads to the production of vast amounts of nitrogen gas in the Pacific Ocean. This
takes place in one of the largest oxygen free water masses in the world -- and
these zones are expanding. This can ultimately weaken the ocean's ability to
absorb CO2.

Climate change: Ocean acidification amplifies global warming
Seafood supply altered by climate change
Date: August 26, 2013
Source: Max Planck Institute for Meteorology
Summary: Scientists have demonstrated that ocean acidification may amplify
global warming through the biogenic production of the marine sulfur component
dimethylsulphide (DMS). Ocean acidification has the potential to speed up global
warming considerably, according to new research.
Date: July 1, 2015
Source: University of Faculty of Science British Columbia
Summary: The global supply of seafood is set to change substantially and many
people will not be able to enjoy the same quantity and dishes in the future due to
climate change and ocean acidification, according to scientists.

Nearly half of U.S. seafood supply is wasted, study shows
Waste adds to other problems threatening global seafood resources such as
overfishing, pollution and climate change
Date: September 23, 2015
Source: Johns Hopkins University Bloomberg School of Public Health
Summary:
As much as 47 percent of the edible US seafood supply is lost each year, mainly
from consumer waste, new research suggests. The findings come as food waste in
general has been in the spotlight and concerns have been raised about the
sustainability of the world's seafood resources. In the U.S. and around the world,
people are being advised to eat more seafood, but overfishing, climate change,
pollution, habitat destruction and the use of fish for other purposes besides human
consumption threaten the global seafood supply.
Restoring ocean health- Analysis of 10 years of monitoring data from marine
protected areas in the Channel Islands finds positive results
Date:September 16, 2015
Source:University of California - Santa Barbara
Summary: More than a decade ago, California established marine protected areas
(MPAs) in state waters around the northern Channel Islands off the coast of Santa
Barbara. Several years later, the National Oceanic and Atmospheric
Administration extended these MPAs into the federal waters of the Channel
Islands National Marine Sanctuary.

'Fish thermometer' reveals long-standing, global impact of climate change
Date: October 10, 2014
Source: University of Faculty of Science British Columbia
Summary: Large numbers of fish will disappear from the tropics by 2050, finds a
new study that examined the impact of climate change on fish stocks. The study
identified ocean hotspots for local fish extinction but also found that changing
temperatures will drive more fish into the Arctic and Antarctic waters.
Date: May 15, 2013
Source: University of British Columbia
Summary: Climate change has been impacting global fisheries for the past four
decades by driving species towards cooler, deeper waters, according to scientists.

Greenhouse gas likely altering ocean foodchain: Atmospheric CO2 has big
consequences for tiny bacteria

Ocean currents disturb methane-eating bacteria
Date: May 4, 2015
Source: CAGE - Center for Arctic Gas Hydrate, Climate and Environment
Source: University of Southern California
Summary: Climate change may be weeding out the bacteria that form the base of
the ocean's food chain, selecting certain strains for survival, according to a new
study.
http://www.sciencedaily.com/releases/2013/07/130702141506.htm
Summary: Bacteria that feed on methane can control its concentration once it is
released from the ocean floor. This can potentially stop the greenhouse gas from
entering the atmosphere. But ocean currents can easily disturb dinner, according
to a new study.

Global warming not just a blanket: In the long run, it's more like tanning oil
Date: November 10, 2014
Source: University of Washington
Summary: Instead of carbon dioxide being like a blanket that slowly warms the
planet, after about a decade most warming comes from melting ice and snow and
a more moist atmosphere, which both cause Earth to absorb more shortwave
radiation from the sun.
