Watts Up With That?

Graphic: The relentless rise of carbon dioxide

Ancient air bubbles trapped in ice enable us to step back in time and see what Earth’s atmosphere, and climate, were like in the distant past. They tell us that levels of carbon dioxide (CO2) in the atmosphere are higher than they have been at any time in the past 400,000 years. During ice ages, CO2 levels were around 200 parts per million (ppm), and during the warmer interglacial periods, they hovered around 280 ppm (see fluctuations in the graph). In 2013, CO2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air.

Today, we stand on the threshold…

http://dailycaller.com/2017/03/21/nonprofits-angry-about-trumps-budget-cuts-hid-the-179-million-they-took-from-the-epa/

From the Daily Caller:

Six nonprofit groups that criticized President Donald Trump’s proposed budget cuts failed to mention the nearly $179 million in Environmental Protection Agency (EPA) grants they’ve received since 2009, according to a Daily Caller News Foundation Investigative Group (The DCNF) analysis of federal spending data.

The agency has funded thousands of such groups since former President Barack Obama’s 2009 inauguration, but The DCNF focused only on six of the largest nonprofit recipients in its analysis of grant data compiled by the watchdog Open The Books.

Another Manntastic claim: Extreme weather events linked to climate change impact on the jet stream

Watts Up With That?

From Penn State, and the “close but no cigar” department (see bold in text) comes this modelspalooza masquerading as science:

On the is an image of the global circulation pattern on a normal day. On the right is the image of the global circulation pattern when extreme weather occurs. The pattern on the right shows extreme patterns of wind speeds going north and south, while the normal pattern on the left shows moderate speed winds in both the north and south directions. CREDIT Michael Mann, Penn State

Unprecedented summer warmth and flooding, forest fires, drought and torrential rain — extreme weather events are occurring more and more often, but now an international team of climate scientists has found a connection between many extreme weather events and the impact climate change is having on the jet stream.

“We came as close as one can to demonstrating a direct link between climate…

Fascinating read Paul. Thank you

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Those who know much better than us would like to return the world’s climate to pre-industrial conditions.

They seem to think the climate was perfect then. Perhaps they should study a bit of history, such as this snippet from HH Lamb’s Climate, History and the Modern World:

Arctic Inversions and Intrusions

An increase in the frequency of intrusions can therefore drive bottom-amplified warming trend even in the absence of sea ice loss. In addition, the intrusions themselves drive sea ice retreat in the marginal zone and thus promote the upward turbulent fluxes that help produce bottom-amplified warming.

Science Matters

An earlier post Arctic Ice Factors discussed how ice extent varies in the Arctic primarily due to the three Ws: Water, Wind and Weather. There are other posts on the details of Water and Wind linked below at the end, but this post looks at some ordinary and repeating Weather events in the Arctic that influence ice formation. An interesting new study prompted this essay, but first some background on heat exchange observations in the Arctic.

Ice Station SHEBA near the beginning of the drift on 28 October 1997. The Canadian Coast Guard Icebreaker Des Groseilliers served as a base of operations for the field experiment. The huts housed scientific equipment and logistical supplies.

One project in particular has provided comprehensive empirical data on the energy interface between Arctic Sea Ice and the atmosphere.  The…

ARCTIC SEA ICE —2017 MAXIMUM—

Nice update Caleb and the sleepy sun look is intriguing. The next few years look like they will offer much for both sides of the political climate divide, but simple humble observers of truth can watch in awe.

Sunrise's Swansong

Barring any last minute peaks, it looks like the sea-ice has reached its yearly maximum.

DMI4 0322 osisaf_nh_iceextent_daily_5years_en

This maximum is about the same as last year, but, because it is among the lowest in the satellite record, I suppose those still involved in the battles with Alarmists should step back and allow them a period of rejoicing. I have never exactly seen the reason for rejoicing, considering they believe low sea-ice signifies the immanent demise of the planet, but I don’t like to spoil other’s fun.

I personally don’t think these slight variations matter as much as others do, and am far more interested in the effects the Quiet Sun. Therefore I have retired from the Climate Wars. However, for those of you still involved, I recommend that, if the celebrating gets too in-your-face and overbearing, the eyebrow approach should be utilized.

This involves listening and nodding, but with overly sympathetic eyebrows…

Is Our Climate Becoming More Extreme?

From 2011 but well worth a revisit.

NOT A LOT OF PEOPLE KNOW THAT

Is our climate becoming more extreme?

There has been much discussion recently about “Climate Disruption” or “Global Weirding”. John Holdren has talked about “increases in floods, wildfires, droughts, heat waves and hurricanes” while Rajendra Pachauri says “Based on observation, we know that there will be more floods, more drought, more heat waves and more extreme precipitation events. These things are happening”.

Al Gore of course is quick to blame any extreme weather event on climate change. Even reputable climate scientists such as Katharine Hayhoe talk about Global Weirding:-

“Heavy rains, deep snowfalls, monster floods and killing droughts are signs of a new normal of extreme U.S. weather events fueled by climate change” scientists and government planners said on Wednesday.

“It’s a new normal and I really do think that global weirding is the best way to describe what we’re seeing,” climate scientist Katharine Hayhoe of Texas Tech University…
