PREDICTIONS BY CLIMATE CHANGE DENIALISTS:
(who inaccurately call themselves sceptics.)

(Sources: e.g. Potholer54, @AtomsksSanakan, @priscian)





2001:


DON EASTERBROOK:
"If the cycles continue as in the past, the current warm cycle should end in the next few years, and global warming should abate, rather than increase, in the coming decades. The beginning of global cooling by 2007 (+/- 3-5 years)"




ROBERT H. ESSENHIGH:
“If the ocean is opening right now, we could possibly start to see the temperature reversal under way in about 10 years.”



2003:


NILS-AXEL MÖRNER:
“global mean temperature... falling by 0.05C 2003-2018.”




2005:


GALINA MASHNICH & VLADIMIR BASHKIRTSEV (Solar physicists):
Bet James Annan 10 000 US Dollars that the planet will cool over the next decade.




2006:

DON EASTERBROOK:
"The current warm cycle should end soon and global temperatures should cool."




2007:


DAVID ARCHIBALD (Geologist):
“The sun drives climate change and it will be colder next decade by 2C"




2008:


SCOTT ARMSTRONG:
Predicted a flat trend from 2008-2017.




TIM BALL:
“We are preparing for warming when it is looking like we are cooling"




PIERS CORBYN:
"Our prediction is world temperatures will continue to decline until 2014 and probably to decline after that."




DON EASTERBROOK:
Predicted cooling seems to have already begun (approx. 2020 temp would be -0.3 - +0.4 C)




WILLIAM GRAY:
"In 10 years I expect the globe to be somewhat cooler than it is now"




GWPF ADVISORS (e.g. Ian Plimer?):
Bet Chris Hope and James Annan that 2015 would be colder than 2008




DAVID DILLEY:
“During 2008 and 2009 the first stage of global cooling will cool the world's temperatures to those observed during the years from the 1940s through the 1970s. By the year 2023 global climate will become similar to the colder temperatures experienced during the 1800s."




2009:


PIERS CORBYN:
Temperatures will fall until at least 2030.




OLE HUMLUM, JAN-ERIK SOLHEIM, KJELL STORDAHL:
“A 1C or more temperature drop is predicted 2009-2020 for certain locations" "This means a global cooling of the order 0.3-0.5C.”




2009:


PIERRE GOSSELIN (NoTricksZone):
“2011-20 decade would not be warmer than 2001-10 decade.”




2010:


DON EASTERBROOK:
"Global warming is over. There may be global cooling."




2011:


JOE BASTARDI:
"I have said the earth will cool 0.1 to 0.2 Celsius in the next ten years, according to objective satellite data."




JAN-ERIK SOLHEIM:
"1.5C decline in Norwegian temperatures during Solar Cycle 24 (2009-2020) compared to Solar Cycle 23"




NEW ZEALAND CLIMATE SCIENCE COALITION:
"It is likely 2011 will be the coolest year globally since 1956."




2012:


CLIFF OLLIER (Geology professor):
Claimed global warming stopped in 1998




2013:


HABIBULLO ABDUSSAMATOV:
Little Ice Age begins at 2015.




OLE HUMLUM:
Predicted in 2013 that the climate would most likely become colder in the coming 10–15 years.




2014:


OLE HUMLUM:
Decrease of 1C until 2020.




KEVIN LONG (Mechanical engineer):
“the world was heading for “the most rapid global cooling trend for two centuries” and that during 2016 this event “should become very obvious to all”"




EIKE:
“He (Sebastian Lüning) thinks it is also possible that the low solar activity will lead to a cooling of one or two tenths of a degree Celsius over the next 5 years.”




2015:


HABIBULLO ABDUSSAMATOV:
Temperatures will decline from 2015




ZHARKOVA:
Solar minimum would be January 2018 (was actually January 2020) and SC25 maximum would be April 2022 (it wasn't)




2016:


NED NIKOLOV:
"all the warming we have observed, pretty much ending in the late nineties... ...it will be becoming cooler from now on."



2018:


NED NIKOLOV:
“In 2 years global temps will fall to the 1998–2013 baseline.”

PREDICTIONS NOT YET FINISHED:


2005:


LINDZEN vs ANNAN BET:
“Global temperatures will be lower in 20 years. If less than 0.2C Lindzen wins, if 0.2C-0.4C bet called off, if 0.4C or greater Annan wins.
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2025)

PIERS CORBYN:
"Corbyn's theory predicts that changes in solar activity will cause “considerable world cooling” by 2040."
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2040)

2009:


JAY LEHR (Heartland Institute):
"we're definitely not only in a cooling period, we're staying in it for a couple of decades"
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2029)

HENRIK SVENSMARK:
“In fact, global warming has stopped, and a cooling so small started. Last week, Mojib Latif from Kiel University at the United Nations World Climate Conference in Geneva announced that the cooling could continue for the next 10 to 20 years."
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2029)

2010:


GIRMA ORSSENGRO:
“its prediction shows global cooling by about 0.42 deg C until 2030”
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2030)

2011:


JUDITH CURRY:
“I made it pretty clear that I supported Tsonis' argument regarding climate shifts and a flat temperature trend for the next few decades.”
HALF-TIME SCORE: FAILED! FULL-TIME: (earliest end 2031)

2012:


LÜNING AND FRITZ VAHRENHOLT:
“Die Kalte Sonne" prognosis: the Earth is entering a cooling phase due to periodic solar cycles and will cool by 0.2 to 0.3 degrees C by 2035.”
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2035)

HABIBULLO ABDUSSAMATOV:
Abdussamatov predicted the onset of a new "mini-ice age" commencing 2014 and becoming most severe around 2055.
SO FAR: FAILED! HALF-TIME SCORE: (in 2033), FULL-TIME: (ends 2055)

2013:


ANASTASIOS TSONIS (University of Wisconsin):
”We are alrealy in cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped.”
HALF-TIME SCORE: FAILED! FULL-TIME: (ends 2028)

2014:


HABIBULLO ABDUSSAMATOV:
“Solar irradiance began to drop in the 1990s.... it will cause a steep cooling of the climate on Earth in 15 to 20 years.”
HALF-TIME SCORE: FAILED! FULL-TIME: (earliest end 2029)

2015:


DIETRICH KOLLE:
“In the next 50 years there would be no temperature increase but rather a slight temperature decrese is expected”

MONCKTON et al.:
“We predict that global-mean temperature will decline to a renewed cooling period in the 2030s and then rise to a new high-temperature period in the 2060s”
SO FAR: FAILED! HALF-TIME SCORE: (in 2040). FULL-TIME (ends 2070)
