The Arctic is full of toxic mercury, and climate change is going to release it
We already knew that thawing Arctic permafrost would release powerful greenhouse gases. On Monday, scientists revealed it could also release massive amounts of mercury -
a potent neurotoxin and serious threat to human health.
Permafrost Stores a Globally Significant Amount of Mercury
Changing climate in northern regions is causing permafrost to thaw with major implications for the global mercury (Hg) cycle.
2017 Was the Hottest Year Yet In the World's Ocean
Warming ocean waters can have harmful impacts on habitats like coral reefs and sea ice, to name a few.
Global Warming Will Increase Risks of Desertification
A new study shows that a global temperature increase of more than 1.5 degrees celsius will mean that dry air will increase significantly,
which can intensify desertification and crop failures. Conversation with Prof. Manoj Joshi, one of the study's authors.
Climate change is turning 99 percent of these baby sea turtles female
Green sea turtles do not develop into males or females due to sex chromosomes, like humans and most other mammals do. Instead, the
temperature outside a turtle egg influences the sex of the growing embryo. And this unusual biological quirk, scientists say, endangers
their future in a warmer world.
Environmental Warming and Feminization of One of the Largest Sea Turtle Populations in the World
Climate change affects species and ecosystems around the globe. The impacts of rising temperature are particularly pertinent in species
with temperature-dependent sex determination (TSD), where the sex of an individual is determined by incubation temperature during embryonic
development. In sea turtles, the proportion of female hatchlings increases with the incubation temperature.
Some like it hot: Scientists figure out why female turtles are born at higher temperatures
Climate Change and Crops
North Americans get most of their protein from animal-sourced foods, but most of the world relies on a handful of staple crops like wheat,
rice, and corn. Climate change may alter the nutritional value of those crops, creating significant health risks, particularly in places
where protein deficiency is already a problem (about 660 million people worldwide are affected).

The most accurate climate change models predict the most alarming consequences, study finds
The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming, according to a recent statistical study released in the journal Nature.
Vanishing Arctic ice could drive future California droughts
California's recent 5-year drought was brutal: Houseboats sat on lakebeds, groundwater supplies dwindled, and thousands of fish literally baked to death. Scientists consider it the worst such event the Golden State has seen in 1000 years.
Now, a new study identifies an unexpected suspect, thousands of kilometers to the north: an iceless Arctic Ocean.
These are the melting glaciers that might someday drown your city, according to NASA
New York City has plenty to worry about from sea level rise. But according to a new study by NASA researchers,
it should worry specifically about two major glacier systems in Greenland's northeast and northwest - but not so
much about other parts of the vast northern ice sheet.
These close-up images from NASA show one of the largest icebergs to ever split off from Antarctica
NASA scientists have captured close-up images of a behemoth iceberg that in July detached from one of the largest floating ice shelves in Antarctica.
Climate Change and Crops
North Americans get most of their protein from animal-sourced foods, but most of the world relies on a handful of staple crops like wheat, rice, and corn.
Climate change may alter the nutritional value of those crops, creating significant health risks, particularly in places where protein deficiency is already a problem
(about 660 million people worldwide are affected). By 2050, a new study projects, 148 million more people, equivalent to 1.6 percent of the world’s projected population,
will be at risk due solely to the impact of carbon dioxide on nutrients. More than a third of them live in India, where the population depends heavily on rice for protein;
nations in sub-Saharan Africa and South America would also be seriously affected. The study, says senior author Samuel Myers, a principal research scientist at the
Harvard T.H. Chan School of Public Health (HSPH), exemplifies an emerging field—planetary health—which has grown from the observation that “human activity is disrupting
our planet to such a degree that it’s coming to be a primary driver of global health.”

Estimates of Sea Level Rise by 2100 Have Tripled in the Past Few Years
In 2013, the Intergovernmental Panel on Climate Change opined that if greenhouse gas emissions continued on current trends,
the likely maximum of sea level rise by 2100 was about one meter. In May 2016, only three years later, a study in the prestigious
scientific journal Nature concluded that if high levels of greenhouse gas emissions continued, oceans could rise by close to two
meters by the end of the century. In less than three years, scientists essentially doubled the IPC's 2013 estimate of maximum sea
level rise by 2100.

What was "unprecedented" about Paris climate agreement?
In December 2015, more than 190 countries, representing the source of more than 95 percent of global greenhouse gas
emissions, met in France for the United Nations Climate Change Conference. Together, they crafted the Paris Agreement
on Climate Change. "It's the first time essentially all the countries of the world have agreed to a common framework
for addressing the problem of climate change," says Andrew Light, University Professor of Philosophy and Public Policy
and director of the Institute for Philosophy and Public Policy at George Mason University.
Polar vortex shifting due to climate change, extending winter, study finds
Global warming could be making winters in eastern North America even longer, according to a new study. The study finds that, because
of sea ice loss in the Arctic, the polar vortex is shifting and temperatures are turning colder during March.
The Plastic Earth
Jerry Mitrovica connects the planet's dynamic history to climate change. The weight of ice sheets in polar
regions can actually flatten the earth's rocky mantle, altering the speed of the planet's rotation and
changing sea levels.
Spatial and temporal distribution of mass loss from the Greenland Ice Sheet since AD 1900
The Greenland Ice Sheet (GIS) is losing mass at an accelerating rate, contributing to global sea level rise.
But are the present rates unusual, compared to twentieth-century variability? It has been difficult to answer this
question because of the shortage of observations before the late twentieth century. Kurt Kjaer and colleagues address
this data gap by analysing a collection of aerial photographs taken in the 1980s.
Assessing the Global Climate in May 2016
The globally averaged temperature over land and ocean surfaces for May 2016 was the highest for the month of May in the NOAA

- CLIMATE ACTION 2016
Climate change is the defining issue of our age. The landmark Paris Agreement reached last December commits all countries
to holding global temperature rise to "well below 2 degrees Celsius". This feat will require economy-wide global and national
transformations. A robust, multi-sector response will be a key component of this solution to pivot societies toward a more
sustainable future for all - the future we want.

"Of the nearly 100 quadrillion British thermal units of energy (BTUs) used each year in the United States,

failing to turn off lights when they leave a room). It is, as Mara Prentiss notes, predominantly fundamental physics: the fuel is burned,
but less than 50 percent performs useful work."

- Modeling the impact of climate change on tropical moist forest dynamics: a hierarchical Bayesian approach
There will be a Colloquium at Georgetown University in Washington DC on climate change.
SPEAKER: Romain Gaspard, CNRS, Université Antilles-Guyane
Identifying, quantifying and predicting the impact of climate change on tropical moist forest dynamics is becoming a matter of urgency. Growth and mortality are the two main processes driving population dynamics. Although these processes are not independent, they are generally modeled separately. In this work we develop a joint growth and mortality model for tropical moist forests that incorporates a set of climatic variables, functional traits and interactions. A Bayesian method is used to select relevant covariates and to estimate the model parameters. This modeling approach formalizes a complex ecological problem and offers a mathematical framework for tropical ecologists to deal with uncertainties at the community level, especially for earlier data with incomplete botanical determinations. The model is applied to a 30-year dynamic data obtained at the Paracou experimental site in French Guiana. We identified three major climatic drivers and found differential species responses according to their functional traits.
