Hottest July On Record Keeps 2015 On Track To Crush 2014 For Hottest Year

August 17, 2015 by Joseph Romm

Global Temperature Records

NASA reports this was the hottest July on record. So we are now in “bet the mortgage” territory that 2015 will be the hottest year in NASA’s 125-year temperature record. In fact, 2015 is likely to crush the previous record — 2014 — probably by a wide margin.[read more]

New Analysis Does Not Support a Warming 'Hiatus'

June 11, 2015 by Henry Auer

The Myth of the Hiatus

Global average temperatures show a break from an earlier high rate of increase. Compared with the preceding three decades, recently recorded global average temperatures have shown only a slight increase. The reduction in the rate of warming of the globe is generally referred to as a "hiatus."[read more]

2014 Was the Warmest Year Globally Ever Recorded

January 21, 2015 by Henry Auer

Temperature Records and Global Trends

2014 had the highest global average temperature ever recorded. The U. S. National Oceanic and Atmospheric Administration and National Aeronautics and Space Administration jointly announced on January 16, 2015 that the year 2014 was the hottest year since record keeping began.[read more]

Deniers Mistakenly Say that Global Warming Has Ended

October 20, 2014 by Henry Auer

Climate Denial and Global Warming

The global average temperature has increased by about 0.7-0.8ºC over pre-industrial temps. A pause of annual global temperatures began after 1997 even though the atmospheric concentration of CO2 continued to increase. Global warming deniers have seized on this to say that warming of the Earth has ended.[read more]

More Evidence Global Surface Temperatures Poised To Rise Rapidly

July 26, 2014 by Joseph Romm

Potential Surface Temp Jump

A new study finds that when climate models factor in the temporary warming and cooling impact of El Niño and La Niña, they accurately predict recent global warming. And that is consistent with recent studies that led one climatologist to say, “Global temperatures look set to rise rapidly.”[read more]

Powering to Climate Mitigation

April 3, 2014 by Jim Baird

Climate Mitigation

Without swift and decisive action to limit greenhouse gas emissions from fossil fuels and other sources, the world will almost surely face centuries of climbing temperatures, rising seas, species loss and dwindling agricultural yields. The smart approach to these threats is power our way past them.[read more]

Is A Super El Niño Coming That Will Shatter Extreme Weather And Global Temperature Records?

March 28, 2014 by Joseph Romm

Super El Niño

Signs are increasingly pointing to the formation of an El Niño in the next few months, possibly a very strong one. When combined with the long-term global warming trend, a strong El Niño would mean 2015 is very likely to become the hottest year on record by far.[read more]

Winter Electricity Price Spikes Put Clean Currents Out of Business

Winter Electricity Prices

The polar vortex weather phenomenon may have passed weeks ago, but the effects are still rippling through the power industry. The most recent victim is the severely affected Clean Currents, a green energy retailer that operated in Maryland, Washington, D.C., and Pennsylvania.[read more]

Global Temperatures: What Climate Hiatus?

November 19, 2013 by Jim Baird

Climate Hiatus and Oceans

Instead of approaching climate change on the basis of sound science, we are in fact actually jockeying to try to be the last standing amongst the planetary ruins. In this world could there be a more Pyrrhic, egotistical, or fruitless objective?[read more]

Climate Departure: New Study Projects Timing of Departure of Climate Variability From Recent Norms

October 21, 2013 by Tom Schueneman

Climate Variability from Recent Norms

Planning for a sustainable future is obviously made much more difficult when a rapidly changing climate is added to the equation. Planning effective policy and development goals will depend greatly on where we find ourselves in ten, twenty, thirty or fifty years.[read more]

Global Temperature Trends and the IPCC

Global Temps and the IPCC Report

As excitement builds about the release of the IPCC report, debate is underway on how to interpret previous IPCC predictions. Such debates involve exegeses of inscrutable IPCC statements via the imperfect process of media (social and mainstream) reporting, colored by agendas.[read more]

Controlling Climate Change: IEA Says It's Not All About Carbon Dioxide

July 13, 2013 by Jessica Kennedy

The International Energy Agency (IEA) has released a World Energy Outlook Special Report warning the world that current climate change policies are on track to far exceed the goal of limiting temperature rise to 2°C.[read more]

OTEC and Energy Innovation: The Willie Sutton Approach

May 15, 2013 by Jim Baird

The average amount of energy the ocean absorbed each year over the period 1993 to 2008 was enough to power nearly 500 100-watt light bulbs for each of the roughly 6.7 billion people on the planet.[read more]

Climate Change: Global Temperatures Still Above Average

May 4, 2013 by Joe Casola

global temperatures

Some skeptics have seized on a recent article in The Economist noting an apparent “hiatus” in global warming to argue that climate change is a fiction and efforts to address it are misguided. So what are the facts?[read more]

Climate Change and the Carbon Bubble Reality Check

May 3, 2013 by David Hone

In recent months there has been a renewed look at the idea of a financial carbon bubble, or unburnable carbon reserves. Carbon mathematics is one thing, but what about meeting global energy demand?[read more]
