Climate change involves natural and man-made changes to weather
patterns that occur over millions of years or over decades.
In the past 150 years, human industrial activity has accelerated
the rate of change in the climate due to the increase in
greenhouse gases (carbon dioxide, methane, and nitrous oxide).
Scientific studies describing this climate change continue to be
produced and its expected impacts continue to be assessed.
In California, the California Environmental Protection Agency has
found temperatures have risen by about 1.5 degrees since 1895.
Looking ahead, temperatures could rise by 2.7 degrees and its sea
levels by 55 inches in the next 40 years, according to the
California Energy Commission and the California Natural Resources
Agency. These are among the ongoing issues the state faces as it
grapples with climate change.
Already, California is confronting rising demand for water and
diminishing supplies. At the same time, the state’s water
infrastructure such as levees is increasingly aging and in
disrepair—conditions expected to be made worse by climate change.
How low can the Colorado go? When will we get back to “normal”
winters? Can we blame it all on climate change? To address
some of these questions, the Colorado River Research Group
recently released a concise four-page paper explaining how
climate change is affecting the river.
In a ruling that has ramifications for land-use and water
policy across the United States and California, a federal
appeals court ruled Monday that scientists can draw on
long-range climate projections to determine whether a species

Climate change from human activity nearly doubled the area that
burned in forest fires in the American West over the past 30
years, a major new scientific study has found, and larger, more
intense fires are all but guaranteed in the years ahead.
Wildfires in California and across the West have become twice
as destructive over the past three decades due to climate
change, taking a toll that will only continue to escalate,
according to research published Monday.

Released today, the study in Scientific Reports — part of the
Nature Publishing Group — found that carbon dioxide and methane
emitted from the burning of fossil fuels may be mimicing the
effects of some catastrophic environmental phenomena the planet
has previously experienced.
As Southern California firefighters battled the Blue Cut Fire
last month, there was nothing they could do to fend off an
unfortunate reality: Global warming is already lengthening
wildfire season and increasing the likelihood of extreme
fires across the West.
So far this 4,636 wildfires in California have burned more than
200,000 acres. That’s more fires than this time last year and
more fires than the five-year average. … California has an
added challenge of dealing with a five-year drought.
President Barack Obama, fixed against a pristine backdrop of
the Sierra Nevada, issued a forceful defense Wednesday of his
administration’s policies to address climate change, warning

Tropical Storm Colin ripped across the Gulf of Mexico in June
and hit the coast of southwest Florida with 60-mile-an-hour
winds. Before it arrived, a team from the U.S. Geological
Survey used a new computer model to predict how far inland the
waves would invade.
California’s iconic natural features, from salmon runs to
Joshua trees, could dwindle or disappear, as climate change
rearranges the state’s weather patterns and landscape, leaving
much of the state hotter and drier, scientists warn.

global warming, according to a study published Monday that used
satellite data to track cloud patterns across about two
decades, starting in the 1980s.
California’s Rim Fire in 2013 was the third largest in the
state’s history, and the 2012 Rush Fire, the second largest.
And last year’s Butte and Valley fires were some of the most
destructive in state history. These grim statistics are part of
an alarming trend in western states: The number of large fires
is growing, and so is the area burned and the length of the
annual fire season.
A speeding wildfire in California that turned hundreds of homes
near Lake Isabella to piles of twisted rubble has forced a
conversation about how to minimize destruction in the most
populous state experiencing the effects of climate change.
California has been diligently trying to reduce use of fossil
fuels and cut greenhouse gas emissions. Last year, Gov. Jerry
Brown signed Senate Bill 350, which requires 50 percent of the
electricity from utilities to come from renewable sources by
2030. But it’s not just energy utilities that can add more
renewables to their portfolios – water suppliers can, as well,
although they aren’t mandated to do so.
To understand what the future holds, sometimes we have to look
at the past, Bruce Daniels has learned. Daniels is trying to
help Californians understand future water availability by
examining 85 years of daily precipitation records. His analysis
has shown that water managers (and the rest of us) have some
reason to be concerned.
Experts say the results of a two-year, $10 million experiment

We often associate climate change with too much water — the
melting ice caps triggering a rise in sea levels. But a new
World Bank report says that it’s too little water — the potable
sort — that we also need to think about.
A mix of rising global temperatures, mysteriously warmed waters
off Baja California and unusually far-reaching storms in
the western Pacific Ocean conspired to block this year’s
El Niño storms from hitting Southern California, the National
Weather Service said this week.
With California entering its fifth year of a statewide drought,
Gov. Jerry Brown moved on Monday to impose permanent water
conservation measures and called on water suppliers to prepare
for a future made drier by climate change.
Global warming has mostly made the weather more pleasant for
Americans over the last 40 years, which may explain why much of
the public doesn’t rank climate change as big a threat as do
scientists and the rest of the world, a new study suggests.
Interior Secretary Sally Jewell on Tuesday called for “a major
course correction” in the way the nation conserves its public
lands, waters and wildlife, saying climate change and other
trends threaten natural areas “in existential ways.”

ranging from climate change to the old, leaky pipes that waste
billions of gallons across the country every day.
President Barack Obama on Monday directed the federal
government to come up with a less reactionary and more
long-term strategy for dealing with drought. … The White
House is hosting a “water summit” on Tuesday, which is World

sufficient and reliable water resources.
California had its warmest winter on record in 2014-2015, with
the average Sierra Nevada temperature hovering above 32 degrees
Fahrenheit – the highest in 120 years. Thus, where California
relies on snow to fall in the mountains and create a snowpack
that can slowly melt into reservoirs, it was instead raining.
That left the state’s snowpack at its lowest ever – 5 percent on
April 1, 2015.
Because he relays stats like these, climate scientist Brad Udall
says he doesn’t often get invited back to speak before the same
audience about climate change.

For years scientists have warned that climate change will cause
melting ice caps, rising sea levels and severe droughts and
floods. But global warming’s effects can also be far more
personal, seriously harming human health.
The worsening of tidal flooding in American coastal communities
is largely a consequence of greenhouse gases from human
activity, and the problem will grow far worse in coming
decades, scientists reported Monday.
After the costliest of wildfire seasons ravaged the West last

The Paris conference brought cheers not only from renewable
energy advocates but from water groups. For years,
organizations that focus on the world’s freshwater resources
felt marginalized in the climate change debate. A warmer planet
means nastier droughts, bigger floods, and unsettling
perturbations in the water cycle, but the question of
adaptation was mostly ignored by diplomats.
