Ocean temperatures off the East Coast of the US are extraordinarily warm for this time of year. A region of water in the Gulf Stream 100 miles off Virginia Beach now features sea surface temperatures of 81 degrees Fahrenheit or 10 degrees (F) above average. To the south and east, in a stormy zone between Bermuda and the Bahamas, temperatures are around 77 degrees Fahrenheit or 4 degrees above average. Readings more typical of July and not at all usual for May in this region of the world ocean.
(Extremely warm sea surface temperatures ranging from 75 to 82 Fahrenheit off the US East Coast contain enough heat potential energy to support tropical storm and hurricane development during late May. Image source: Earth Nullschool.)
Ocean heat is a primary driver of tropical cyclone formation. And record warm 2016 land and ocean surfaces contributed to the January formation of hurricane Alex in the Northeastern Atlantic this year. An unprecedented January-forming hurricane that organized five months before the typical start of hurricane season on June 1. Now, a low pressure center swirling between the Bahamas and Bermuda on Thursday appears to be developing tropical or subtropical characteristics in what may become Bonnie — the second named tropical cyclone of 2016 — over the next few days.
Weather statements from the National Hurricane Center (NHC) at 2:55 PM Eastern Standard Time noted that conditions would become more favorable for tropical cyclone development over the next 24-48 hours. And the Center predicted that a tropical cyclone was 60 percent likely to form over the next two days and 70 percent likely to form over the coming five. The NHC also warned that all coastal interests from Georgia to North Carolina should monitor the progress of this developing low.
(An area of disturbed weather in the lower right hand portion of this image may form into tropical storm Bonnie over the next two to five days. Image source: The National Hurricane Center.)
Current satellite imagery indicates high, cold cloud tops associated with thunderstorm formation north of the low’s center of circulation. Forecast models indicate a west-northwest storm track that ultimately brings the low on shore near the North Carolina – South Carolina border on early Sunday morning. Models then predict that the low will stall out, hovering over the coastal Carolinas for the next 3-4 days.
If Bonnie does reach tropical storm strength it will only be the fifth time two tropical storm or hurricane strength cyclones have ever formed before June 1 since record keeping began in 1794. It’s also worth noting that the January formation of Hurricane Alex already makes the 2016 season one for the record books. Increasing ocean surface temperatures across almost all basins due to a fossil-fuel emissions based warming of the world is likely to result in a higher likelihood of such out-of-season storms all while increasing the potential maximum strength of the strongest storms. And recent events in the Pacific, Atlantic, and Indian oceans seem to bear out these predicted trends.

/ May 27, 2016So El Niño / La Niña historically have had the greatest impact on seasonal storms (summer). Off-season storms aren’t frequent enough for trend determination. That said, El Niño was in full swing when Alex formed and El Niño is now technically present but fading.
This summer, a trend toward La Niña conditions will tend to reduce wind shear and increase the frequency of low pressure system formation. This has traditionally increased the number of Atlantic basin storms. Near average water temps off Africa (if slightly cooler in some areas) may slightly suppress initial formation of trans Atlantic storms. But above average SSTs near the US East Coast and in the GOM will tend to kick storm strength higher as systems approach. These far above normal SSTs would also tend to enhance formation in the western Atlantic. We’ve already had two storms. And I think 15-19 is a good estimate overall for 2016.

Attorney Generals investigating them about their efforts to suppress information about climate change and manufacture doubt about the science. Major publications openly criticizing them.

I kinda find it funny that the Exxon CEO is claiming that humanity needs oil when all the company efforts have been aimed at forcing dependence on oil. It’s not that humanity needs oil at all. Pretty much everything coming out is showing that these guys have been trying to remove people’s choices for alternative energy sources from jump. That’s where the fraud comes in. It’s not just lying about climate change. It’s lying and generating myths about the importance of a single energy source in order to keep markets captive. With wind and solar and low cost batteries and EVs, we don’t need to burn oil. And the oil companies know that it’s just a matter of economies of scale before those sources are in position to fully replace fossil fuels. They’ve probably known this since at least the 1970s and pretty much all communication and political effort has been aimed at denying and delaying just such a rapid scaling up.
And since that such a scale-up would be difficult and require major investments and large-scale political effort, the oil companies like Exxon were in an excellent position to sabotage that process. The first act of sabotage was supporting climate change denial. But the second act of sabotage is in the active attempts to deny access to renewable energy sources.

(Extract
The biggest long-term threat to the GBR today, and to its ecosystems services, biodiversity, heritage values and tourism economy is climate change, including rising sea temperatures, accelerating rates of sea level rise, changing weather patterns and ocean acidification. (Great Barrier Reef Marine Park Authority 2012). Coral reefs worldwide are being directly impacted by warming waters and ocean acidification and climate change is exacerbating other localized stresses (Hoegh-Guldberg et al 2007). Ocean acidification is occurring because of increased levels of carbon dioxide in the atmosphere. A significant portion (about 25-30%) of this CO2 is being absorbed by the oceans and the resulting increases in seawater acidity reduces the capacity of some marine life, such as corals, to build their calcium carbonate based skeletons. Significant drops in coral growth rate have been recorded in the last two decades for massive Porites corals on the Great Barrier Reef.

These responses are maladaptive to climate change — they will generate more conflict and put more stresses on nations and civilizations. And Trump’s push to return to fossil fuels would be equivalent to the shift back to coal that has been so disastrous for Australia. We’d jump back to something worse than the Bush years — because even Bush funded renewable energy development programs. From Trump’s rhetoric, and the various policies that the republican Congress is attempting to put out, it appears that the goal is to crush the current and wide-ranging advances we are now experiencing in renewables.

Back in 1978, almost four decades ago, Black made ominous warnings about the potential perils of climate change to come if humanity did not stem fossil fuel usage and reverse course.
“In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels,” Black told Exxon higher-ups, according to InsideClimate News’ reporting, in a presentation titled “The Greenhouse Effect.” “Present thinking holds that man has a time window of five to ten years before the need for hard decisions regarding changes in energy strategies might become critical.”
As Kalinsky alluded to, Exxon spent $31 million dollars funding the climate change denial machine between 1998 and 2014 — by conservative estimates.

http://conservativetransparency.org/recipient/heartland-institute/page/3/?order_by=year%20DESC
The above link is for a search on the Heartland Institute funding.
The impression I got was that ExxonMobil directly funded only a small amount of the climate change denial machine. Most of the funding was from conservative charitable foundations, that jumped in to do the majority of the funding, as is common for most of the causes the the Right wants to fund in an deniable way, I think.
The whole structure was designed to be deniable and immensely complex, I think. Investigations are going to be difficult.
The majority of the funding comes from the Koch associated foundations (Donor’s Capital Fund, Donor’s Trust, Koch, and Lambe). The Donor’s foundations do not disclose their funding sources, making them a sort of legal money laundering operation. More funding comes from the Scaife foundations (Carthage), the Bradley foundation, the Walton family (WalMart), and others I don’t know much about.
Looking these funding sources up on the SourceWatch website can be informative, and bewildering.
As a publicly traded corporation, ExxonMobil is subject to more public scrutiny than Koch Industries, which is privately held. The conservative foundations like Bradley, Koch, and Scaife, are subject to very little public or tax scrutiny at all because these are “charitable” tax free foundations.
I personally think that the Rockefeller financial establishment, of which ExxonMobil is only a part, used their immense influence to get climate change denial funded in a deniable way, but that is just speculation on my part.
Certainly, if ExxonMobil wanted to use the Kochs as funding cutouts, for example, there are lots of ways ExxonMobil could arrange to legally pay the Kochs for goods or services – just speculation on my part of course.

>>>”We are talking about 250 active methane seeps found at relatively shallow depths: 90 to 150 meters” says oceanographer Benedicte Ferré from CAGE.
According to her, it is the sea itself that adds obstacles to methane emissions to the atmosphere in the summer. The weather is generally calm during summer, with little wind. This leads to stratification of the water column whereby layers of different density form, much like oil over water.
This means there is no or low exchange of water masses between the surface layer and the layers below. A natural barrier occurs, acting as a ceiling, preventing the methane from reaching the surface. But this condition does not last forever: wind blowing over the ocean can mix these layers, causing this natural barrier to disappear. Thus the methane may break the surface and enter the atmosphere. <<<<<

“”Estimates on how much methane gas is stored beneath the seabed as hydrates vary enormously. A recent calculation suggests that we are talking about 74 000 gigatonnes, and one gigatonne is a billion tonnes”, says professor Jürgen Mienert, director at CAGE.”
That’s about 74 trillion tons of carbon as methane stored as methane hydrates – on the order of 10 times the recoverable amount of all the other conventional fossil fuels combined, not including oil shales and tar sands, if this estimate is correct. This estimate by Klauda and Sandler has been questioned in the deep ocean, but just on the continental shelves they estimate 29 trillion tons of carbon as methane, worldwide. That’s a lot of carbon, stored in a form of water ice that will inevitably melt when exposed to heat, sooner or later, faster or slower. A calculated 12 trillion tons of carbon as methane apparently came out of the hydrates during the End Triassic,suggesting that the high estimates are more realistic than the low ones.
It’ s been known for a long time that the oceans will act as a barrier to methane transfer into the atmosphere. But, according to modeling by the IMPACTS group of national labs and universities, resource shortages will make whole ocean basins anoxic, and add increasingly to direct transfer of methane into the atmosphere, as the oceans’ capacity to oxidize methane becomes increasingly exhausted. They calculate direct transfer of methane into the atmosphere of 60% in methane release hot spots by year 30 of their methane release scenario.

Right now, methane is very potent, with a global warming potential over 20 years of roughly 80 times that of CO2. As methane concentrations increase, this will tail off, and methane itself will in fact end up less potent than CO2, when methane concentrations become equal to CO2 concentrations. But methane has added atmospheric and oceanic chemistry effects that will increase its lifetime, from 8 years now to maybe 40 years or more, increasing it’s potency. And methane oxidation directly injects water vapor – the strongest greenhouse gas – into the stratosphere. And methane ultimately ends up as CO2, adding to global warming for thousands of years.
The methane does not “get chewed up” by bacteria in the oceans – it gets oxidized into CO2 or bicarbonate. So, even as the oceans act as a barrier to atmospheric transfer of methane, they become increasingly acidic and anoxic in doing so, and eventually methane releases locally overwhelm the oceans’ ability to oxidize methane, as methane increasingly is released directly into the atmosphere,

/ May 29, 2016Hi Cate-
A further complicating factor in methane consumption by bacteria – ocean currents. From another article on the site you link to:
http://phys.org/news/2015-05-ocean-currents-disturb-methane-eating-bacteria.html
“Future methane release from the ocean to the atmosphere will depend on ocean currents.
“We were able to show that strength and variability of ocean currents control the prevalence of methanotrophic bacteria”, says Lea Steinle from University of Basel and the lead author of the study, “therefore, large bacteria populations cannot develop in a strong current, which consequently leads to less methane consumption.””
So strong ocean currents can sweep methanotroph bacteria away from the vents, allowing more direct transfer of methane into the atmosphere.

/ May 27, 2016When the deniers say how good more CO2 will be for crops…not even close. Another in the endless research showing consequences we never anticipated.
“Poison Packed – Crops are becoming toxic to withstand extreme weather conditions”
That is the dire message the United Nations Environment Programme (UNEP) has delivered through a report released during its second general assembly this week. Scientists who wrote the report say extreme weather conditions and rising temperatures will make 70 percent of the world’s agricultural production toxic to animals and humans across the globe.

/ May 28, 2016Thanks for the alert – there is a lot of emerging issues in that UNEP report . . . . . . . . .
Changes in climatic patterns also have serious implications for food safety and security. Toxin accumulation in a variety of crops
is one manifestation of climate change impacts that presents further challenges to agriculture and food production. Prolonged
drought and high temperatures can trigger biophysical reactions in plants leading to an accumulation of chemical compounds
toxic to animal and human health. Environmental stressors associated with climate variability can also make plants become more
susceptible to infection by toxin-producing pathogens that, again, lead to toxin accumulation.
