About the Claims That Northeast U.S. Blizzards Have Been Amplified by Human-Induced Global Warming

The media has been abuzz with claims that the January 2015 New England Blizzard was worsened by human-induced global warming.  One of the outspoken activist members of the climate science community who has been quoted often on the storm is NCAR’s Kevin Trenberth.  An example of Trenberth’s interviews can be found in the ClimateNexus post Blizzard of 2015: Normal Winter Weather, Amplified by Climate Change.  The subtitle is actually quite funny, bringing back the old “consistent with climate models” nonsense: “Above average sea surface temperatures increase snowfall, consistent with model projections.”

Kevin Trenberth is reported to have written about the January 2015 New England blizzard: Continue reading

What are Your Fears about Global Warming and Climate Change?

The title question is rarely, if ever, asked of people who are skeptical of human-induced global warming and climate change…for obvious reasons.  If persons are skeptical of a future filled with climate catastrophes, regardless of whether they are caused by nature or by emissions of manmade greenhouse gases, then there should be few reasons for them to be fearful of future climate.    Continue reading

New Paper Claims Extreme La Niñas to Become More Frequent under Global Warming

The new 2015 paper by Cai et al Increased frequency of extreme La Niña events under greenhouse warming has been getting a lot of alarmist attention recently. Examples: see the CBS News story Climate change expected to bring more La Niñas, and the  BBC News article Study: Global warming ‘doubles risk’ of extreme weather,  and, for those of you who are multilingual, see the German journal  Bild der Wissenschaft post Mehr Besuche der kalten Schwester von „El Niño”.  [Thanks to bloggers Alec aka Daffy Duck, Paul Homewood and Werner Kohl for the heads-up.]  Also see Paul Homewood’s post BBC – Global Warming Doubles Risk Of Extreme Weather at NotALotOfPeopleKnowThat.

An Introduction to Oceanic Kelvin Waves at the NOAA ENSO Blog

We discussed downwelling and upwelling equatorial Kelvin waves in almost every post of 2014/15 El Niño Series.  NOAA recently published a post titled Oceanic Kelvin waves: The next polar vortex*.  The post was written by NOAA’s Michelle L’Heureux and reviewed and edited by NOAA’s Bill Kessler.  It confirms our basic discussions of those phenomena, but describes them in terms that are even more basic. If you have questions for NOAA, that thread at their ENSO blog would be a good place to ask them.

An Unexpected Admission from Dana Nuccitelli at SkepticalScience

In Dana Nuccitelli’s recent post at SkepticalScience Matt Ridley wants to gamble the Earth’s future because he won’t learn from the past, he has finally admitted something we’ve been discussing for more than 6 years. (His article was also cross posted at The Guardian here. Yes, that’s the zombie post that has gained so much attention.) Continue reading

NODC Data Continue to Indicate the Deep Oceans are Warming in Some Basins But Not Others

UPDATE:  I forgot to note that the data in Figure 1 have been zeroed at the year 2003.  That was done to simplify the illustration.
# # #
The National Oceanographic Data Center (NODC) recently updated their ocean heat content and vertically averaged temperature data for the oceans to depths of 2000 meters.  See the NODC data webpage here.  Alarmists are having a grand time trying to scare their readers with their chicken-little end-is-near proclamations. Example: see the post titled “The oceans are warming so fast, they keep breaking scientists’ charts” at SkepticalScience here and The Guardian here.  Also see Joe Romm’s post ‘Hottest Year’ Story Obscures Bigger News: Ocean Warming Now Off The Charts at ClimateProgress.  Continue reading

NASA GISS & NOAA NCDC Need to Be More Open with the Public when Making Proclamations about Global Warming Records

We discussed the 2014 global surface temperature announcements by NASA GISS and NOAA NCDC in the posts On the Biases Caused by Omissions in the 2014 NOAA State of the Climate Report and Does the Uptick in Global Surface Temperatures in 2014 Help the Growing Difference between Climate Models and Reality?

GISS expresses no doubt that global surface temperatures in 2014 were the highest on record in their news release dated January 16, 2015…same thing with their YouTube video NASA | 2014 Warmest Year On Record.  And as we noted in the “Biases of Omissions” post, a reader must scroll down well beyond the Global Highlights to find the uncertainties in the NOAA 2014 State of the Climate report…and click on a link to find out what those uncertainties mean.  The mainstream media had a field day, summing up the GISS and NCDC announcements with alarmist sound-bites.  Continue reading

December 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS and NCDC through December 2014 and HADCRUT4 through November 2014—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through December 2014.

On the Biases Caused by Omissions in the 2014 NOAA State of the Climate Report

[Update:  Corrected a few typos in the paragraph before Figure 4. My thanks to rogerknights.]

I hadn’t read the NOAA State of the Climate (SOTC) Report for 2014 when I prepared the post Does the Uptick in Global Surface Temperatures in 2014 Help the Growing Difference between Climate Models and Reality?  (WattsUpWithThat cross post is here.) I simply presented data and climate model outputs in that post.

The following are a few observations about the annual NOAA report. NOAA biased their report by omitting key discussions.  Continue reading

Calamities Oversold

The overselling of calamities in environmental sciences has reached unseemly proportions…so much so in one field that in 2014 a team of marine researchers exposed the problems in a journal article. The paper is Duarte et al. (2014) Reconsidering Ocean Calamities. The abstract reads (my boldface): Continue reading
