Now Live · Open to All
Synthesis by Berkeley Earth is now open
From observation to decision.

Synthesis by
Berkeley Earth is now live and open to
everyone at synthesis.berkeleyearth.org.
For those who
joined our launch preview earlier this month
with C40 Cities, thank you. The platform you
saw is now public, with the final pieces in
place.
Synthesis brings
together 250+ years of Berkeley Earth's
observational record with bias-corrected,
downscaled temperature projections to answer a
direct question for any city on Earth: what
has the climate done here, and what is it
likely to do next. No one lives at the global
average, and Synthesis is built to meet
decisions where they are actually made, at the
local scale.

|
What is new since the preview
|
| • |
Monthly updates
are live. The observational
record on the platform is current through
May 2026, and observations will refresh on
a monthly cadence going forwards. |
| • |
Decision-ready
metrics are available. TAVG and
TMAX projections are available now for
more than 8,000 cities. Cooling and
heating degree-day series, projected TMAX,
and days >35°C are now loaded for an
initial set of cities, with others
available on request. |
| • |
Custom applied
metrics. Beyond the standard
series, we can generate custom applied
metrics for specific research, planning,
and investment questions, from growing
degree days and overnight highs, to frost
days and expanded city and regional
coverage. Reach out to
discuss what would be most useful
for your work. |
| • |
Licensing.
Synthesis is available to academic,
public, media, and nonprofit users under a
CC BY-NC license. For commercial licensing
and other institutional applications,
reach out to ad...@berkeleyearth.org. |

Of Note
Extreme heat, in focus
|
|
Europe's record-smashing heatwave last week
pushed June temperatures past long-standing
marks in several major cities, just as forecasts
call for a significant extreme-heat event across
the Eastern United States over the July 4th
holiday weekend. For more on these and other
recent extreme events, see the resources and
reporting below.

The March 2026
Western U.S. Heatwave
The
largest March temperature anomaly in the
170-year record, with roughly 30 percent
of U.S. weather stations setting new
monthly records. The event was driven by
a blocking-ridge "heat dome," the same
class of pattern now parked over Europe.

Why temperature
records are being not only broken but
smashed
By
Mark Poynting, Climate Researcher, BBC
News
On
why recent records are being exceeded by
such large margins. Berkeley Earth Chief
Scientist Robert Rohde is quoted,
calling the margin of records across the
western U.S. “utterly absurd.”

Europe’s record
heatwave: does the continent have a new
climate?
By
Edward Chen, Nature
Berkeley
Earth Research Scientist Zeke Hausfather
is quoted on Europe's warming rate
outpacing the global average, a trend he
says is “pretty glaringly obvious in the
data.”
