Water_V

 

It has been brutally hot, for days. Yesterday was really hard on me:

changed my clothes a couple of times, went to pick up 4 liters of water

and struggled to get it home.


Don't want to cook to warm up the place, end up eating cheese on toast. A

few hours later, I smell like a cow. Another bath, another change of clothes...

You get the idea.


6:30pm, I'm starting to run out of juice and soda; should do a quick run to a 

convenience store. I'm exhausted and opening the door to the balcony blasts me

with heat, maybe I could just allow myself to stay in, drink water and forget the jingling

glasses of pop, although there is no real sign of rain, except for that small band of rain for

7pm on MSNW. Remember to check the Radar page of MSN Weather. Are there rain cells 

forming in the area, none from the West, where they usually come from. Then, wacko, big cloud

coming in from the North. Decide to take this as a sign, with enough probability to

influence me to choose to stay home. 


Got out of the bath twenty minutes later, swing the curtain open at the entrance to the balcony.

Utter surprise: IT IS RAINING CATS AND DOG!! Copilot has taken me through decades of

not reading weather reports correctly. I now know how to decide on whether to go out

or not from a weather app!!


None too soon, I might add. Just learned yesterday morning there is now more water

vapor in the atmosphere than usual, which means more rain coming through. An

explainer, below:

Heatwave; I have started consulting the radar map before going outside, even if nothing looks ominous. This actually saved me from a serious downpour which came out of nowhere ( the NORTH-West) last night. What can you tell me about how a radar recognizes a storm cell...

It is great that you are using radar data to stay ahead of the weather; that "out of nowhere" downpour you experienced is a perfect example of why these tools are so valuable. Modern weather radars, specifically **Pulse-Doppler** systems, act as both a high-tech "eyesight" and a "speedometer" for the atmosphere.

Here is how a radar essentially "recognizes" a storm cell:

 1. Reflectivity: Mapping the "What" and "How Much"
When you look at a radar map, the colored patches represent **Reflectivity**. The radar fires a beam of microwave energy that travels through the air at the speed of light. When that beam hits precipitation (raindrops, ice, or hail), some of that energy bounces back to the radar antenna.
* **The dBZ Scale:** The strength of that returning signal is measured in decibels of Z (**dBZ**).
* **Size and Count Matter:** The radar doesn't just see "rain"; it interprets the intensity. Because the energy return is proportional to the **sixth power** of the diameter of the particle, even a few large, heavy hailstones can trigger a much higher, "red-level" reading than a massive cloud of light mist.
* **Interpreting the Map:** You are essentially seeing a density map of water in the sky. When you see those intense, clustered blobs of orange, red, or purple, the radar is telling you that the concentration of water particles in that specific "pulse volume" of air is extremely high—the hallmark of an active storm cell.

 2. Doppler Shift: Mapping the "Motion"
While reflectivity tells you where the rain is, the **Doppler effect** tells you what it is doing. As the radar beam hits moving rain particles, the frequency of the returning wave shifts:
* **Compression (Higher frequency):** If the particles are moving toward the radar, the waves are "squashed," creating a shift the computer recognizes as inbound motion.
* **Stretching (Lower frequency):** If the particles are moving away, the waves are stretched, indicating outbound motion.
By analyzing these shifts, meteorologists (and your radar app) can identify **rotation** within a storm or detect **outflow boundaries**—the leading edge of cool air rushing out of a storm—which is often what triggers that "out of nowhere" rain you experienced as the storm approaches from the North-West.

 3. Scanning: Building a 3D Picture
Radar doesn't just look at one slice of the sky. It performs a **Volume Coverage Pattern (VCP)**, which means the antenna physically tilts higher and rotates multiple times. This allows the system to build a 3D model of the storm.
* A "storm cell" is often identified by its vertical growth. By looking at the higher "tilts," the radar can see if a cell is reaching high into the atmosphere (where temperatures are colder), which is a major indicator of potential hail or severe weather.

 Why you felt it came "out of nowhere"
Storms don't always move at the speed of the surface wind. They move based on the winds at the altitude where the storm "lives" (often thousands of feet up). A cell can be forming or strengthening rapidly in the upper atmosphere while the air at ground level is still calm and clear.

By checking the radar, you are essentially looking at the **integrated data** of these three processes:
1. **Reflectivity** (Intensity/Density)
2. **Velocity** (Direction/Speed)
3. **Volume Scanning** (Vertical Development)

It is a clever way to turn physics into a safety tool. Have you noticed if your app shows "velocity" or "wind" modes in addition to the standard rain intensity view?

But seriously... The Economist shows us how American opinion currently divides. And

this is well reflected in political affiliation. Whatever else (and I'm thinking guns, here), 

America is a strong democracy.

Now_What(CUSMA)

 Copilot:

Did President Trump actually declare there would be no renewal for the North American Free Trade Agreement or not. I have read conflicting reports between the English and French CBC...

Short answer:  

Yes — President Trump did publicly declare that he was not looking to renew the North American Free Trade Agreement’s successor (CUSMA/USMCA). Multiple reputable English‑language sources confirm that he stated the U.S. would not renew the agreement in its current form. The French and English CBC reports may differ in tone or emphasis, but the underlying fact is consistent: Trump said he was not looking to renew the deal.

🧭 What Trump actually said

Across several outlets, Trump made clear statements indicating:

He is “not looking to renew” the Canada‑U.S.-Mexico Agreement (CUSMA/USMCA). 

He said he “may sign” it but also “would rather not have the agreement.” 

He stated the agreement is “not renewed” because the U.S. declined to agree to renewal at the July 1 review deadline. 


U.S. Trade Representative Jamieson Greer confirmed:

“The United States did not agree to renew the USMCA in its current form. As a result, the USMCA is not renewed.” 

These statements were made in June and July 2026 during the mandatory six‑year review window.


πŸ‡¨πŸ‡¦ Why CBC English and French may seem contradictory

CBC English reporting emphasizes Trump’s explicit comments about not renewing the agreement and his musings about letting it “expire immediately.”

CBC French reporting sometimes frames the situation more cautiously, focusing on:

The process (review vs. renewal)

The fact that the agreement remains in force until 2036 unless a country withdraws

The possibility of annual reviews rather than outright termination

This can make the French coverage sound less definitive, even though the underlying facts match the English reporting.


🧩 Clarifying the confusion

Here’s the key distinction that often gets lost:

Trump’s statements: He said he does not want to renew the agreement.


The legal reality:

The U.S. declining renewal does not immediately end the agreement.

It triggers annual reviews instead of a 16‑year extension.

CUSMA/USMCA remains in force unless a country formally withdraws with six months’ notice.

So Trump did declare no renewal — but that does not mean the agreement ended.


✔️ Bottom line

President Trump did declare that the U.S. would not renew the NAFTA successor agreement (CUSMA/USMCA).

The English CBC reports this more directly; the French CBC may emphasize the procedural nuance, but they are describing the same underlying decision.

If you want, I can compare specific English vs. French CBC articles side‑by‑side to show exactly where the wording differs.


Aren't there more meetings planned??

Yes — there are more meetings planned, but the nuance matters. Let me break it down clearly so you can see why the reporting feels contradictory.

🧭 Where things actually stand now

The USMCA/CUSMA review process didn’t end with Trump saying he wouldn’t renew the agreement. His refusal to renew simply means:

The deal did not receive the automatic 16‑year extension.

Instead, it enters a period of annual joint reviews.

Those reviews require meetings every year between Canada, the U.S., and Mexico.

So yes — more meetings are planned, because the treaty requires them when renewal is not granted.


This is why French CBC sometimes sounds calmer: they emphasize the process continuing.

English CBC tends to focus on Trump’s political declaration (“not looking to renew”).

Both are technically correct, but they highlight different parts of the same reality.


πŸ—‚️ What meetings are expected next

Here’s the structure:

1. Annual USMCA/CUSMA Joint Review Meetings

These are mandatory once a country declines renewal.

They happen every year until 2036.

Purpose: renegotiate, adjust, or reaffirm commitments.


2. Bilateral Canada–U.S. and Mexico–U.S. follow‑up meetings

These are already being discussed informally.

They focus on:

automotive rules of origin

agriculture

digital trade

border and customs modernization

dispute resolution mechanisms


3. Minister‑level trade meetings

Canada’s Minister of International Trade has already stated publicly that Canada expects more meetings in the coming months.

Mexico has said the same.


4. Possible leader‑level meetings

Not formally scheduled yet, but both Canada and Mexico have indicated they are open to them.

Trump has said he is willing to meet “if necessary,” though he has also said he prefers bilateral talks over trilateral ones.

🧩 Why the confusion?

Because “no renewal” does not mean “no more meetings.”

It means more meetings, but under a different legal framework.

English CBC: focuses on Trump’s political messaging (“not renewing,” “deal not renewed”).

French CBC: focuses on the treaty mechanics (“annual reviews continue,” “negotiations ongoing”).

They’re describing the same situation from different angles.


✔️ Bottom line

Yes, Louise — there are more meetings planned, and in fact the treaty requires them now.

Trump’s declaration didn’t end the process; it changed the process.

If you want, I can pull up the exact CBC English vs. French wording and show you precisely where the difference in tone comes from.


What are the sticking points Mexico/USA, Canada/USA and what then happens between Canada and Mexico?

Louise, here’s the clearest, most structured breakdown of the actual sticking points between each pair of countries — Mexico–USA, Canada–USA, and Canada–Mexico — based on the 2026 USMCA/CUSMA review process and official statements. I’ll keep this grounded in what reputable sources report, and you should always confirm political information with trusted news outlets.

πŸ‡²πŸ‡½ Mexico–USA: The Major Sticking Points

These are the most contentious issues right now.

1. Energy Sector Sovereignty

Mexico insists on:

State control over electricity generation

Priority for PEMEX and CFE

Limits on foreign (especially U.S.) private energy investment


The U.S. argues this violates:

National treatment rules

Market access commitments

Environmental obligations

This is one of the biggest flashpoints.


2. Labor Enforcement & Border Manufacturing

The U.S. wants:

Stronger enforcement of labor rights in Mexican factories

Faster inspections

Higher wages in auto plants


Mexico says:

The U.S. is overreaching

Inspections are politically motivated

Wage demands distort competitiveness


3. Agriculture (Corn, GMO, Phytosanitary Rules)

Mexico’s restrictions on:

GMO corn

Certain pesticides

U.S. meat imports

The U.S. claims these are non‑science‑based barriers.


4. Migration & Border Trade Logistics

Not part of the trade agreement directly, but:

Border congestion

Security inspections

Trucking rules

These spill over into trade talks and create friction.


πŸ‡¨πŸ‡¦ Canada–USA: The Major Sticking Points

Canada’s issues with the U.S. are different — less explosive than Mexico’s, but still serious.


1. Dairy Market Access

The U.S. says Canada:

Still restricts U.S. dairy imports

Uses quota allocation to favor Canadian processors


Canada says:

It is following the agreement

Supply management is non‑negotiable

This is a long‑standing fight.


2. Digital Trade & Data Localization

The U.S. wants:

Stronger protections for cross‑border digital services

Limits on Canadian data‑localization rules


Canada wants:

More flexibility to regulate digital platforms

Privacy protections

Ability to impose taxes on large U.S. tech firms

This is a new and growing sticking point.


3. Automotive Rules of Origin

The U.S. wants:

Stricter rules

Higher domestic content

More U.S. steel and aluminum


Canada wants:

Flexibility

Recognition of integrated North American supply chains

This is a technical but important dispute.


4. Softwood Lumber (Not formally USMCA, but always present)

The U.S. maintains duties.

Canada wants them removed.

This dispute never dies.


πŸ‡¨πŸ‡¦πŸ‡²πŸ‡½ Canada–Mexico: What Happens Between Them?

Canada and Mexico do not have major bilateral disputes under USMCA. Their relationship is mostly cooperative.

But if the U.S. refuses renewal, Canada and Mexico must decide how to coordinate their positions.


Key dynamics between Canada and Mexico:

1. They may form a “common front”

On:

Automotive rules

Labor enforcement mechanisms

Dispute resolution panels

Digital trade rules


Both countries prefer:

Predictable rules

Multilateral dispute panels

Less U.S. unilateralism


2. They may negotiate side agreements

If the U.S. pushes for bilateral deals, Canada and Mexico might:

Strengthen their own bilateral trade ties

Harmonize standards

Coordinate supply chains

This is already being discussed informally.


3. They must manage “triangular pressure”

If the U.S. demands concessions from one country:

It affects the other

It shifts supply chains

It changes competitiveness


Example:

If Mexico agrees to higher auto wages, Canadian plants become more competitive — or vice versa.

4. Canada and Mexico share concerns about U.S. unpredictability

Both countries:

Want stability

Prefer multilateral rules

Oppose sudden U.S. tariff threats

This creates natural alignment.


🧭 Bottom Line

Here’s the simplest summary:


πŸ‡²πŸ‡½–πŸ‡ΊπŸ‡Έ Most contentious:

Energy sovereignty, labor enforcement, GMO corn, border logistics.


πŸ‡¨πŸ‡¦–πŸ‡ΊπŸ‡Έ Moderately contentious:

Dairy, digital trade, auto rules, softwood lumber.


πŸ‡¨πŸ‡¦–πŸ‡²πŸ‡½ Least contentious:

Mostly coordination issues — not real disputes.

Canada and Mexico may increasingly work together if the U.S. pushes for bilateral renegotiations.

If you want, I can map out how these disputes affect Quebec specifically, or what Canada’s likely negotiation strategy will be in the next round of meetings.


Are there major upsets for Canada, and Quebec, as we move into this new negotiation pattern?

Louise, here’s the clearest, most practical breakdown of what Canada — and specifically Quebec — stands to lose, gain, or worry about as the USMCA/CUSMA shifts into annual renegotiation cycles. I’ll keep this grounded in reputable reporting and treaty mechanics, and you should always confirm political information with trusted news sources.


πŸ‡¨πŸ‡¦ Major Upsets for Canada (National Level)

These are the areas where Canada faces real vulnerability as the negotiation pattern changes.

1. Dairy Market Access Pressure (Huge for Quebec)

This is Canada’s #1 political and economic pressure point, and Quebec is the epicentre.


The U.S. wants:

More access to Canada’s protected dairy market

Changes to quota allocation

Reduced power for supply‑managed sectors


For Quebec, this touches:

Milk

Cheese

Yogurt

Specialty dairy (Quebec’s artisanal sector is large)


Why it’s an upset:  

Supply management is politically untouchable in Quebec.

But the U.S. sees it as the “last big protectionist wall” in North America.

Annual reviews mean the U.S. can push this issue every single year, instead of once every 16 years.


2. Digital Trade & Data Rules (Affects Quebec’s tech and AI sector)

The U.S. wants:

Fewer restrictions on American digital platforms

Limits on Canadian privacy and data‑localization rules

Protection for U.S. cloud and AI companies


Canada wants:

Stronger privacy protections

Ability to regulate big tech

Flexibility for Canadian AI companies


Upset for Quebec:  

Montreal’s AI ecosystem (MILA, startups, research labs) depends on:

Data sovereignty

Privacy rules

Local cloud infrastructure

If the U.S. pushes hard, Quebec’s digital policy autonomy could shrink.


3. Automotive Rules of Origin (Ontario-heavy, but Quebec is affected too)

The U.S. wants:

Higher U.S. content

More U.S. steel and aluminum

Stricter verification


Canada wants:

Flexibility

Recognition of integrated supply chains


Upset for Quebec:  

Quebec’s electric vehicle and battery supply chain (Lion Electric, Nemaska Lithium) could face:

Higher compliance costs

More paperwork

Pressure to source U.S. materials

Not catastrophic, but annoying and expensive.


4. Softwood Lumber (Always a thorn)

The U.S. maintains duties.

Canada wants them removed.


Upset for Quebec:  

Quebec’s forestry sector is large, especially in the Saguenay, Abitibi, and CΓ΄te‑Nord regions.

Annual reviews mean this fight never ends.


5. Border & Customs Modernization

The U.S. wants:

More inspections

More security measures

Faster digital customs systems


Canada wants:

Predictability

Less friction


Upset for Quebec:  

Manufacturers exporting to the U.S. (Saint‑Jean, Montreal, Estrie) may face:

Delays

Higher compliance costs

More paperwork


πŸ‡²πŸ‡½πŸ‡¨πŸ‡¦ What Happens Between Canada and Mexico?

Canada and Mexico do not have major disputes.

But the new negotiation pattern forces them into a strategic triangle with the U.S.

Here’s what changes:


1. Canada and Mexico may form a “common front”

On:

Automotive rules

Labor enforcement

Dispute panels

Digital trade

This benefits Canada because Mexico often absorbs the political heat from the U.S.


2. Canada and Mexico may negotiate side agreements

If the U.S. pushes for bilateral deals, Canada and Mexico might:

Strengthen their own trade ties

Harmonize standards

Coordinate supply chains

This could help Quebec’s manufacturing and agricultural sectors.


3. Canada and Mexico must manage “triangular pressure”

If the U.S. demands concessions from one country:

It affects the other

It shifts competitiveness

It changes supply chains

Example:

If Mexico agrees to higher auto wages, Canadian plants become more competitive — but Mexico may demand compensation elsewhere.


4. Canada and Mexico share concerns about U.S. unpredictability

Both countries:

Want stability

Prefer multilateral rules

Oppose sudden tariff threats

This alignment helps Canada.


🧭 Bottom Line for Quebec

Here’s the simplest, most honest summary:


Biggest risks for Quebec:

Dairy market access (the #1 political and economic vulnerability)

Digital trade rules (Montreal’s AI sector)

Forestry/softwood lumber

Manufacturing compliance costs


Moderate risks:

EV supply chain rules

Border logistics


Low risks:

Agriculture outside dairy

Services

Tourism


Potential gains:

Stronger Canada–Mexico cooperation

More predictable auto rules if Canada and Mexico align

Opportunities in digital regulation if Canada holds firm


If you want, I can break down exactly how Quebec’s dairy sector could be affected, or what Canada’s negotiation strategy is likely to be in the next round of meetings.

Sounds to meet that the structure of the negotiating process - initially agreed to - makes it possible

for the US to change governments and style of governing. What about Canada, and Mexico in all

this. This is one aspect - going forward - that might be worth thinking about...

Something

 Very nice presentation of some of the issues surrounding the Big Bang theory.

Indeed, sold me on the idea that asking what came before the Big Bang as a way of asking

how something could come from  nothing is silly. There was something there, and to 

the extent that the initial singularity is accepted, then one needs to ask what conditions could have 

left things in that state. What could have enabled such a crunch.


In effect, this is the intial insight of theistic creationism. Still holds. So why something

instead of nothing. Don't invest in it. It seems more logically easy, only it's false.

Dangerously_Hot

 It's a heatwave, and we need to take things seriously!!



Wet Bulb warnings:


                                                                     *     *     *

So what happens if it rains at 28C, which is what is supposed to happen later today?

Rain at 28 °C is one of the trickiest and most dangerous heat‑wave situations because rain pushes humidity toward saturation, which can drive the wet‑bulb temperature sharply upward even if the air temperature doesn’t rise. This is exactly the kind of scenario that makes heatwaves in Quebec feel suddenly oppressive.

Here’s what actually happens — and why it matters.

🌧️ 1. When it rains at 28 °C, humidity often jumps toward 90–100%
Rain adds moisture to the air and reduces evaporation.

When humidity rises:

Sweat stops evaporating efficiently
The body loses its main cooling mechanism
Wet‑bulb temperature climbs toward the air temperature

This is the mechanism behind dangerous humid heat.
As explained in heat‑stress guidance, wet‑bulb temperature rises as humidity increases because evaporation slows down, reducing the body’s ability to cool itself .

🌑️ 2. What the wet‑bulb temperature becomes at 28 °C with rain
Let’s estimate:

Scenario A — Before rain (65% humidity)
WBT ≈ 24–25 °C  
→ Caution / High stress for vulnerable people

Scenario B — During rain (90–100% humidity)
WBT jumps to 27–28 °C  
→ Danger zone

This matches published heat‑stress categories where wet‑bulb temperatures in the 24–28 °C range correspond to high to dangerous heat stress, requiring reduced activity and careful monitoring .

If humidity hits 100%, WBT ≈ air temperature → 28 °C WBT, which is a level where exertional heat illness risk increases sharply. WBGT‑based guidance shows that WBGT values above 28 °C correspond to red‑zone danger, where only light activity is recommended and heat‑stroke risk rises dramatically .

πŸ”₯ 3. Why rain can make heat feel worse, not better
Rain cools the air a little, but it also:

Eliminates evaporative cooling

Makes the air feel “heavy” and suffocating

Causes sweat to sit on the skin

Increases risk of dizziness, nausea, and heat exhaustion

Medical guidance notes that high humidity traps heat inside the body, increasing risk of dehydration, heat exhaustion, and heatstroke even when temperatures are not extremely high .

So a rainy 28 °C can feel more dangerous than a dry 33 °C.

🧭 4. What this means for you today
You’re at the start of a heatwave, and rain at 28 °C is a classic “hidden danger” moment.

Expect:

Sticky, oppressive air
Sweating that doesn’t cool you
Higher heart rate
Fatigue or mild headache indoors
Outdoor exertion becoming risky
If you’re in a home without strong AC, this is when rooms start to feel “stuffy” and uncomfortable.

πŸ›‘️ 5. How to protect yourself during rainy heat

Avoid outdoor exertion during or right after the rain
Use fans to increase evaporation (they help even in humid air)
Drink water steadily
Take cool showers if you feel overheated
Keep blinds closed to reduce indoor heat load
Check on older adults or anyone with heart/lung conditions

πŸ” Want me to calculate the exact WBT for your location when the rain starts?
Just tell me:

the temperature
the humidity (or I can estimate based on typical rain values)

I’ll place it on your heat‑risk scale and tell you how dangerous the next few hours will be.

Renamed

 The renamed GST (Goods and Services Tax) credit - Essentials - should be

paid out this Friday. For the exact amount one could receive, the number

is on the individual's account with Revenue Canada.


So how would all this evolve over the next five years. The formula is ever

the same: The base is the old GST amount, indexed for inflation every year at

July. One then adds 25%... what makes this an aid for meeting essential expenses

when it is groceries and connex items that are showing large price increases.


So let's this in action. What might the amount be for 2027??


The maximum for an individual this July is 169.75$ per quaterly payment. Removing

the 25% top up, the base amount is thus 135.80. Now let's assume there is 3% inflation

over 2026. The base amount then becomes 139.87. Adding 25% to that gives 174.84.


And there we have it, our payment for 2027!!
