New California Climate Report Warns of ‘Climate Whiplash’, Extreme Heat, Longer Summers, Eroded Beaches
We’ve just had two of the mildest summers in recent memory

Assessment)
By 2100, California will have longer summers and more extreme heat, deadlier wildfires, diminishing snowpack, 3.3 feet of sea level rise, eroded beaches and “climate whiplash”, according to California’s Fifth Climate Change Assessment.
What is this doomsday report? Taxpayers unwittingly paid for this drivel, mandated by legislation passed during the statewide Covid lockdowns:
California’s Climate Change Assessments are a cornerstone of the state’s efforts to understand and prepare for a changing climate. Since 2006, California has published four statewide assessments, each building the scientific foundation needed to understand climate risks and inform policies, investments, and resilience actions. California’s Fifth Climate Change Assessment builds on this foundation while responding to new direction from Senate Bill 1320 (Stern, 2020), which requires the State to report the projected impacts and risks of climate change across California at least every five years.
Who knew?
Senate Bill 1320 by Sen. Henry Stern (D-Los Angeles), passed in 2020, requires the state to develop the California Climate Change Assessment at least every five years. It was approved by Governor Gavin Newsom in September 2020, and took effect January 1, 2021.
Up to $11 million was made available to implement California’s Fifth Climate Change Assessment. Separate provisions allocated $6 million related to the Fifth Climate Assessment under the Natural Resources Agency. So we’re up to $17 million for this climate hysteria.
The former Office of Planning and Research, now the Office of Land Use and Climate Innovation, through the Integrated Climate Adaptation and Resiliency Program (ICARP), must develop the assessment in coordination with the Natural Resources Agency, the California Energy Commission (State Energy Resources Conservation and Development Commission), and the Strategic Growth Council, and in consultation with partner public agencies.
“Climate Innovation?” Really?
California’s Fifth Climate Change Assessment, released October 19, 2026, projects rising temperatures, declining snowpack, more extreme heat and wildfire smoke, greater sea-level rise risks, and disproportionate impacts on vulnerable communities and tribes, while emphasizing that the future is not predetermined and that adaptation actions can reduce risks.
This sounds ominous.
California’s Fifth Assessment primarily uses international climate models, greenhouse gas (GHG) emissions scenarios, and time periods, and is the most recent version of a “global collaboration” that standardizes and combines the most advanced climate models to project how Earth’s systems will react to our changing atmosphere. “With CMIP6, we can see the most likely climate trends and the less likely, but still possible, extremes.”
Hold that thought: “most likely climate trends” and “less likely extremes.” $17 million taxpayers paid for this report only to have the authors admit extremes are less likely.
Whew. I’m relieved.
According to broadcast meteorologist Anthony Watts, “California has always been a land of meteorological extremes. Its Mediterranean climate naturally produces long dry periods punctuated by episodes of tremendous precipitation. Atmospheric rivers carrying Pacific moisture into the state are not a recent creation of climate change. They are fundamental to California’s hydrology.”
He highlights California’s Great Flood of 1861-1862, in which “powerful storms battered California for weeks. Rivers overflowed, levees failed, Sacramento flooded, and enormous portions of the Central Valley disappeared beneath water. The USGS describes the event as remaining ‘unparalleled in its magnitude.’”
“The storm sequence lasted approximately 45 days. The Sacramento Valley became an inland sea.”
As for climate whiplash, “California does not alternate between drought and deluge because its climate has suddenly become unstable. Alternating between drought and deluge is normal for California’s climate,” according to Watts.
As for California’s atmospheric rivers, Watts says the USGS calls them California’s primary storm mechanism and notes that just a few large atmospheric river events can determine whether a particular year is wet or dry.
Remember 2021? 2022? Big atmospheric rivers, and we are going to see more this year as well.
Gird your loins… or pour a cocktail… this is from the doomsday report – California’s Fifth Climate Change Assessment:
■ California will experience rising temperatures across the century. Average temperatures in California are increasing at an unprecedented rate, projected to rise by 3.5–4.3°F (1.9–2.4°C) by 2050 relative to the 1981–2010 baseline. By 2100, projected temperature increases range between 5.7°F (3.2°C) under an intermediate emission scenario to 8°F (4.4°C) under a high emission scenario.
By 2100 we’ll all be dead. How convenient. Al Gore only predicted 10 years out; these climate hysterics won’t make that mistake.
■ California will experience greater precipitation variability and more “climate whiplash,” – swings between wet and dry extremes.
■ California’s snowpack will decline substantially, affecting downstream water systems, local economies, and ecosystems.
■ Climate change is reshaping California’s seasons, altering the timing, duration, and intensity of seasonal conditions.
Weather changes. Seasons change. Climate is about change.
■ Wildfire smoke exposure and associated health risks are increasing. Models project that California will experience the highest increase in annual excess deaths from wildfire smoke of any US state by 2050, reaching over 5,000 excess deaths per year compared to 2011–2020.
24 years from now, if California’s out-migration declines, there will likely be more people in the state, thus more deaths. But they can’t really quantify this claim.
Farmworkers alone are projected to experience a 190% increase in smoke exposure days considered “unhealthy for sensitive groups” by mid-century.
There is the basis for outlawing California’s agriculture industry.
■ Extreme heat events are growing longer and more frequent, resulting in prolonged heat waves and more days above important temperature thresholds. By end-of-century, the average longest heat wave of the year is projected to lengthen across all regions of the state, with durations ranging from six days in the Bay Area to as long as 19 days across the Sierra Nevada under a high emissions scenario.
“By the end of the century” means 2099… who will be around to prove or disprove this absurd theory?
■ Climate risks are not distributed equally across California communities. For example, people living unsheltered (0.5% of California’s population) make up 13% of all hospitalizations for heat-related illness.
It stands to reason that people living on the streets (unsheltered) are going to be more impacted from heat and rain.
■ Marine and coastal ecosystems are being reshaped by marine heat waves, ocean acidification, and hypoxia. Ocean acidification along the California coast is occurring at twice the global rate due to upwelling.
Upwelling is a natural feature of the California Current System – an eastern boundary upwelling zone.
■ With 3.3 feet of sea level rise $78 billion worth of property and 201,000 people could be exposed to coastal flooding by 2100. This means five times the exposure expected in 2050. A 100-year storm could raise these estimates to 310,000 people and $122 billion in property exposed by 2100.
People COULD be exposed to coastal flooding. A 100-year storm COULD raise these estimates. Not that anyone knows if they absolutely will.
■ California Native American tribes face disproportionate impacts from climate change yet are leading effective climate adaptation solutions. Historical land dispossession and criminalization of traditional practices have heightened tribal vulnerability to shifting seasons and climate-related hazards. Nonetheless, California Native American tribes are implementing strategies such as ecocultural restoration and cultural burning which can reduce the likelihood of catastrophic wildfires by up to 92% for a decade post-treatment. These practices strengthen ecosystems, communities, and California’s overall adaptive capacity.
So tribal communities are allowed to “culturally” burn “to reduce the likelihood of catastrophic wildfires?” Curious.
■ Climate hazards are increasingly interconnected, creating cascading and compounding risks. Major climate hazards in California are most destructive when they occur sequentially or simultaneously. For example, an exceptionally hot summer and fall in 2024 exacerbated fire conditions leading into the 2025 Los Angeles Fires, one of the most expensive natural disasters in US history.
The 2025 Los Angeles fires were man-made, but the rapid, destructive spread was enabled by severe Santa Ana winds, and critically dry vegetation that had not been cleared.
■ Climate change will have significant economic impacts across California, particularly through the effects on health and labor. For example, recent extreme heat events have led to billions of dollars in losses through premature death, lost work hours, and more, while rising global temperatures are increasing the pace of inflation.
Where have recent significant economic impacts happened? In Europe, and particularly the EU and western/southern European countries Italy, Germany, France, and Spain, according to Bloomberg.
■ The future is not predetermined. The decisions made today can help California adapt to a changing climate and strengthen resilience for generations to come.
This bombast is epic and manipulative. You need to know what the climate hysterics are saying to justify California Democrats’ ongoing, destructive and very expensive climate legislation.
But, in the long run, you are much better off arming yourself with climate facts at Watts Up With That?
Did I do a proper job of mocking this $17 million buffoonery?

How can they predict what is going to happen by 2100 and they can’t tell us if it is going to rain in two weeks.
Katy, Awesome Job in addressing this buffoonery!! My only comment would be to add a quote or 2 from this riveting peer reviewed 2008 USGS Study — First Clear Climate Link. The paper “Principal hydrologic responses to climatic and geologic variability in the Sierra Nevada, California” by David H. Peterson, Iris Stewart, and Fred Murphy as it was the first to document, in a peer‑reviewed scientific context, that warming mountain winters and springs were causing a shift from snowfall to rain, earlier snowmelt, and a reduced water supply from snowpack. It’s amazing that people can keep on producing this type of snake oil and that some people still actrually but it.
