GREENLAND ICE SHEET SIXTH HIGHEST ON RECORD

by GWPF, December 7, 2019


In 2018, Greenland’s total  surface mass budget (SMB) is almost 150bn tonnes above the average for 1981-2010, ranking as sixth highest on record.

 

The Danish Meteorological Institute (DMI) also performs daily simulations of how much ice or water the Ice Sheet loses or accumulates. Based on these simulations, an overall assessment of how the surface mass balance develops across the entire Ice Sheet is obtained (Fig. 4).

At the end of the 2018 season (31 August 2018), the net surface mass balance was 517 Gt, which means that 517 Gt more snow fell than the quantity of snow and ice that melted and ran out into the sea.

WORLD COOLING – BUT RAPID WARMING FORECAST

by David Whitehouse, February 7, 2019 in GWPF


Average global temperature has been falling for the last 3 years, despite rising atmospheric CO2 levels.

 

2018 was the fourth warmest year of the instrumental period (started 1850) having a temperature anomaly of 0.91 +/- 0.1 °C – cooler than 2017 and closer to the fifth warmest year than the third. But of course there are those that don’t like to say the global surface temperature has declined.

Les émissions de CO2 des États-Unis en forte hausse en 2018

by Connaissance des Energie, 22 janvier 2019


Après trois années de baisse, les émissions américaines de CO2 liées à l’énergie auraient augmenté de 3,4% en 2018 selon les dernières estimations du cabinet Rhodium Group. Explications.

Une hausse des émissions malgré la baisse de consommation de charbon

Les émissions américaines de CO2 liées à l’énergie auraient connu en 2018 (+ 3,4%) leur deuxième plus forte hausse annuelle des deux dernières décennies, après 2010 (+ 3,8% dans un contexte de reprise économique après la crise de 2008) selon les dernières estimations de Rhodium Group publiées le 8 janvier.

La consommation de charbon a pourtant significativement baissé aux États-Unis en 2018 selon l’EIA. Dans le secteur électrique, le « King Coal » s’efface peu à peu au profit du gaz naturel, plus compétitif (avec l’exploitation du gaz de schiste) : la part du charbon dans la production nationale d’électricité aurait atteint 28% en 2018 (et pourrait encore diminuer à 26% en 2019), contre 35% pour le gaz naturel selon le Short-Term Energy Outlook de l’EIA publié en décembre dernier.

Is the forecasted El Niño for this year fading away? It sure looks that way.

by Anthony Watts, January 8, 2019 in WUWT


In late 2018, there were some predictions that there would be a significant El Niño event in 2019. There were strong hints of an El Niño event in both SST data and forecasts. In an April 6th 2018 essay, Bob Tisdale suggested  “Looks like one may be forming right now.”

But if we look at the animation provided by NOAA’s Climate prediction center, it sure looks like it has been fading:

Arctic Sea Ice Extent Higher Than 2006 Last Month

by P. Homewood, January 9, 2019 in NotaLotofPeopleKnowThat


Just last March, the Guardian was trying to panic us about record lows in Arctic sea ice during last winter.

Back in the real world, DMI confirm that average Arctic sea ice extent in December was higher last month than in 2006. In reality, there has been very little change at all since 2005.

UK Climate Trends – 2018

by P. Homewood, January 4, 2019 in NotaLotofPeopleKnowThat


The Met Office has now published its data for 2018. We can expect plenty of claims about last year being the 7th warmest in the UK since records began (in 1910). Or that all of the ten warmest years have occurred this century.

The real significance of these latest numbers, however, is that they continue to confirm that UK temperatures stopped rising more than a decade ago, after a step up during the 1990s.
