Understanding the role of the sun in climate change

Dr. Scafetta offers a new analysis of the sun-climate issue, with fresh research. Clearly a crucially important topic in climate science, where certain pre-conceived ideas have dominated the discussion in recent years, to the point of refusing to even have one.

Although the sun provides nearly all the energy needed to warm the planet, its contribution to climate change remains widely questioned, says Nicola Scafetta.

Many empirically based studies claim that it has a significant effect on climate, while others (often based on computer global climate simulations) claim that it has a small effect.

The Intergovernmental Panel on Climate Change (IPCC) supports the latter view and estimates that almost 100% of the observed warming of the Earth’s surface from 1850–1900 to 2020 was caused by man-made emissions. This is known as the anthropogenic global warming (AGWT) theory.

I addressed this important paradox in a new study published in Geoscience Frontiers.

New research ponders consequences of ocean iron fertilization

Any deliberate large-scale interference in natural processes must be fraught with risks and difficulties. Nevertheless some scientists think they should seek to impose their will on nature, invoking climate models and CO2-obsessed theories as the excuse.

Removal of excess carbon dioxide in the atmosphere, in addition to major reductions in ongoing emissions, is required to stave off the most severe consequences of climate change, claims EurekAlert [Talkshop comment – without offering any evidence].

Large-scale ocean iron fertilization is one of several strategies that could help remove carbon dioxide, but new research published this week in Global Change Biology by a Bigelow Laboratory for Ocean Sciences researcher and colleagues shows that it might also negatively affect marine ecosystems in far corners of the ocean.

Using advanced models of ocean biogeochemistry and ecology, the team showed that iron fertilization in the Southern Ocean could exacerbate climate change-driven nutrient shortages and productivity losses in the tropics, potentially hurting the coastal fisheries on which many people rely.

The findings illustrate both the interconnected nature of the ocean and the need for more objective research on the relative advantages and unintended consequences of marine carbon dioxide removal.

Sunspot Counts Hit 21-Year High

.

Another busy month for cycle 25.

Spaceweather.com

July 2, 2023: The sun is partying like it’s 2002. That’s the last time sunspot counts were as high as they are now. The monthly average sunspot number for June 2023 was 163, according to the Royal Observatory of Belgium’s Solar Influences Data Analysis Center. This eclipses every month since Sept. 2002:

Solar Cycle 25 wasn’t expected to be this strong. When it began in Dec. 2019, forecasters believed it would be a weak cycle akin to its immediate predecessor Solar Cycle 24. If that forecast had panned out, Solar Cycle 25 would be one of the weakest solar cycles in a century.

Instead, Solar Cycle 25 has shot past Solar Cycle 24 and may be on pace to rival some of the stronger cycles of the 20th century. The last time sunspot numbers were this high, the sun was on the verge of launching the Great Halloween Storms

As predicted, wind industry blackmails the UK – demands yet more subsidies – Net Zero Watch

Forget the cheap electricity hype. The Oliver Twists of the loss-making renewables business are raising their voices again.
– – –
London, 5 July – Net Zero Watch has urged the Government to stand up for consumers and businesses by rejecting the wind industry’s latest demands for more subsidies.

In a move that gives the lie to years of propaganda claiming falling costs, the wind industry’s leading lobbyists have written to the Government, threatening to abandon the UK unless there are hugely increased subsidies for their companies (see RenewableUK press release).

The industry is claiming that unforeseen rising costs now necessitate and justify three actions:

Dimwits: Biden WH Considers Blotting Out The Sun’s Rays To Slow Global Warming

Do they finally admit that tinkering with trace gases is a nonsense and the Sun is the real climate issue, supposing that there is an issue? They might want to consider possible adverse effects on weather systems and agriculture, not to mention solar PV output, for starters. Legal actions blaming governments for the weather, or even potential future weather, have already started in various countries.
– – –
The wanton destruction of priceless art and heritage sites across Europe by climate change activists is insane, and one would think we’ve reached peaked insanity with this unhinged community, short of acts of eco-terrorism.

Nope, says Climate Change Dispatch.

Sometimes, even banal actions, like a government study, can exhibit more ludicrousness than smearing paint on a Monet.

The latest Biden White House-endorsed study into curbing global warming is not just a case study in wasteful spending; it’s a Rorschach test on mental health.

New study reveals abrupt shift in tropical Pacific climate during Little Ice Age

Earth and climate – an ongoing controversy

Evidence that what is today called ‘climate change’ can naturally occur, and has occurred, over a relatively short timescale – described here as ‘remarkable’. Maybe history is trying to tell us future climate conditions are more unpredictable than advocates of IPCC doctrines would have us believe.

An El Niño event has officially begun, says Science Daily.

The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes.

El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past by an international research team led by Ana Prohaska of the University of Copenhagen and Dirk Sachse of the German Research Centre for Geosciences (GFZ).

Irony Alert: Why Offshore Wind Power Increases Carbon Dioxide Gas Emissions

.
.
A reminder that green industrialization is mostly fuel-powered.

STOP THESE THINGS

Wind power is delivered chaotically, it’s costly and critically depends on the weather. So, the only purported justification is said to be a reduction of carbon dioxide gas emissions in the electricity generation sector. Putting aside whether there’s any need to do so, STT is happy to attack the myth that wind power does any such thing.

One of our posts to that effect – How Much CO2 Gets Emitted to Build a Wind Turbine? – has clocked up over 130,000 hits and still attracts attention.

In the first of the pieces below, David Wojick tackles the myth that offshore wind power generation reduces carbon dioxide gas emissions, explaining that collapses in wind power output are met by using costly to run and highly inefficient open cycle gas turbines, ramped up to keep the grid from collapsing and the lights on when calm weather sets in. With the net result…

Arctic Ice in Surplus June 2023

‘
‘
Data shows Northern Hemisphere ice extent remains greater than the 17 year average for this particular month.

Science Matters

The animation shows Arctic ice extents on day 151 (end of May) through yesterday June 30, 2023  As usual, the Pacific basins Bering and Okhotsk (far left) became ice-free and are no longer included in these updates. Years vary as to which regions retain more or less ice.  For example, this year Hudson Bay (bottom right) lost half its ice by June 30, earlier than average.  That is a shallow basin and can quickly lose its ice in coming days.  Despite this early melting, the NH Ice extent remains greater than the 17 year average.

The graph below compares the June monthly ice extents 2007 to 2023 and compared to the SII 17 year average.

Clearly June ice appears as a plateau, and most years MASIE shows greater extents than SII, with differences of only a few 100k km2.  Previously 2019-20 were in deficit to average, but June 2022-3 have…

King Charles III starts ‘climate clock’ countdown to 2030 after repeatedly changing timetable

Here we go again. Do this, don’t do that, and somehow the globe will cool down a bit.
– – –
King Charles III helped activate a “Climate Clock” at a London forum on Wednesday, counting down the time until 2030, the alleged time allotted to avoid the worst effects of climate change, despite the UK King offering several different timetables in years past, says Just the News.

The Climate Clock countdown began at the Climate Innovation Forum during London’s 2023 Climate Action Week. Founder and CEO of Climate Action, Nick Henry, said it serves as a “visual reminder of the urgency of the climate crisis,” according to Fox News.

“TIME IS RUNNING OUT” and “ACT TODAY SAVE TOMORROW” were just a few of the interchanging slogans on the jumbotron that displayed the Climate Clock. The button to activate the clock was pressed by London Mayor Sadiq Khan while accompanying King Charles III on stage at the event.

The European Commission on Wednesday (28 June) called for international talks on the dangers and governance of geoengineering, saying such interventions to alter the climate posed “unacceptable” risks, reports Euractiv.

The European Commission on Wednesday (28 June) called for international talks on the dangers and governance of geoengineering, saying such interventions to alter the climate posed “unacceptable” risks.

Geoengineering has attracted increasing interest as countries fail to cut greenhouse gas emissions fast enough to curb climate change. But the issue of manipulating planetary systems to fight global warming remains highly controversial.
