Earth had its 6th-hottest July and year to date on record

>July marked the 46th-consecutive July and the 451st-consecutive month with temperatures above the 20th-century average.

This is the better fact.

>This made it the sixth-hottest July in the 143-year global climate record.

This provides good context. (Followup question: Given some random distribution, how often should you experience a "6th hottest month" with records starting a particular year?)

>The five warmest Julys on record have all occurred since 2016.

Not exactly sure based on the wording here, but I think an entirely true headline with the opposite impression would be "Earth had it's coolest July since 2016"

Thank you for breaking this down. Headline is clearly biased.

In what direction?

Editors are clearly anti-planet

Make mars great again

Darn Romans. Make Ares Great Again is such a better acronym.

Isn't there something weird about comparing a point to an average that includes itself? There have not been 46 Julys in the 21st century so the average 20th century temperatures are including some of those consecutive months of highs.

It just expresses the fact that temperatures have been rising already over the 20th century. It would make sense to make the comparison even in 1999.

A little surprised to see these posts still crop up when to me it seems like these records aren't news anymore, but rather the expectation. I saw someone on here point out that instead of repeatedly saying "this is the hottest X on record" we should start saying "this is expected to be the coolest X for the next 100 years".

Your alternate headline implies global warming is on a trend towards cooler days, which we definitely do not want to imply as it’s not true.

Not really, you misread. to

Edit; Well, maybe you didn't. But what's 100 years from now if we don't manage to tackle global warming...

At this point i feel so much guilt for driving (on weekends now and then) a guzzler that i’d rather throw it to the bin and never look back. Either way i am never again driving an ice car.

You should check out https://www.carboncounter.com

If you drive very little and mostly on the highway, a mini ICE car may be more efficient than an electric car (due to the fixed emissions associated with producing the battery). Of course, an electric (or even hybrid) vehicle) is a far, far better choice for the vast majority of drivers.

Chart confirms SUV's are worse greenhouse emitter than sedan.

So does this chart not include fixed costs? Because there isn’t a single ICE in chart that’s better than any Electric as far as I can see.

The whole model is dynamic, so you can go into settings and drop the amount of miles you drive per year down, which should bias towards ICE.

FWIW, that chart doesn't really substantiate your words. In fact just a tiny handful of plugin hybrids (really just the Ioniq and Prius Prime) reach the lifetime carbon impact seen by even the median EVs. And obviously that demands that the plugin be driven mostly as an EV (i.e. actually be plugged in regularly), something that has been frustratingly false for most deployed vehicles.

If you do 2k miles per year only and all on the highway ICE cars do look favorable. But that is a very atypical circumstance (however, one that OP might be in)

If you want to be serious about your individual impact, use a personal carbon footprint calculator. It could be that there are other actions you can take that have a lesser impact on your lifestyle. I see many people wasting their energy on cosmetic changes. Also, don’t forget that you have a limited power on the lifestyle you have. Many decisions that destroy the environment are outside of our control.

I stopped in favour of riding a bicycle. It's nicer. I still own a motorcycle and a car, but I hardly use them anymore. It doesn't feel like a sacrifice because it's genuinely more pleasant.

However I visit the home country once a year and I see twenty cars lined up at a drive through with their engines running. It makes me feel like a sucker for even trying.

Nothing you do individually makes any difference at all. Don't feel guilty.

Manufacturing a new EV with all the attendant impact from raw materials processing and manufacturing vs keeping an older ICE car where all of that is sunk costs not a clear win in my view.

Does this narrative hold true if we replace the individual with “everyone”? How many people does it take to reach a “significant” change?

According to a recent Reuters article using a model developed by the Argonne National Laboratory in Chicago, the point at which an EV’s carbon footprint meets and begins to fall below that of a comparable gas vehicle in the United States is at around 13,500 miles.

So after an average year of driving, the EV is better for the environment.

Same reason no one should bother voting.

A win is replacing the trips you can with a bike.

>The five warmest Julys on record have all occurred since 2016.

It doesn't apply south of the border???

Every day at lunch I Google: "Mexico City temp"

Always in the 70s...

August 15, 2022

71°F°C Precipitation: 14% Humidity: 51% Wind: 6 mph Mexico City, CDMX, Mexico Monday 12:00 PM Mostly cloudy

Mexico City is at 2200 meters. High altitude is going to be cooler.

July also isn't the hottest part of the year there. April or May is.

Then you should know that Mexico City is similar to SF in that there are not extreme temperatures. Mexico City average high temperature monthly.. the low is 72 and the high is 81.

Are you seriously trying to cherry-pick a single outlier to refute a planet-wide data set?

FWIW: if your point was that you were expecting Mexico City to be hot like Cancun, you need to check a map. The city is in the middle of a mountain plateau at 7000' MSL!

Cherry picking a single event is exactly what happens all the time trying to convince me climate is change is real. Every news article I read about basically any weather "anomaly", whether a flood, drought, hurricane, fire, heatwave coldsnap or tornado, blames the event on climate change. If you're against argument from anecdotes, the pro climate change side of the isle has a huge mote to remove from their own eye.

I don't think you can pick one locale and argue anything based on that. I've lived in the Midwest USA my whole life (over 50 years). The weather seems about the same as always. I remember 100 degree days when I was a kid in the 1970s. They are rare but they happen occasionally then as now (we haven't been above mid-90s here yet this year). July and August are hot and humid, as always. I can't say that I've noticed any trends up or down, but that doesn't mean that the data on global averages are wrong.

Here's the plot of 1980-2022 july temperatures (global land-ocean). Note it's a bit of a plateau since 2016 or so, but that if you eyeball a running 8-yr average it's a steady climb.

The comparison to January is kind of interesting (these are anomaly plots off a 1900 - 2000 base period, not absolute)

https://www.ncei.noaa.gov/cag/global/time-series/globe/land_...

Note these are global averages so effects like winter vs. summer don't really show up.

This is a La Niña year, and we still had record breaking heatwaves all across the north hemisphere. I'm not sure how much worse things will be during El Niño years, that are supposed to be hotter.

> Antarctica had a record-low July sea ice coverage for the second month in a row at 5.75 million square miles

What does this mean? How are there two july's in a row? Did they mean the "second year in a row"? If they were actually comparing july to june, well of course july is colder than june. Bleagh. I have no idea.

Edit: Wait, wait, yes, july is colder than june, so I don't know how it could come up with less ice... argh I still don't get this

>If they were actually comparing july to june, well of course july is colder than june.

Why is July of course colder than June? The winter solstice was on June 21, right? I am not sure of the solstice is the coldest time, but could you explain this?

In the last couple of years I felt like a party pooper when I brought global warming topic and its connection to consumption such as fossil fuel, meat, etc. My personal lifestyle is obviously insignificant no matter how low in CO2. But I still express my bad feeling about it and I hope more people make the same associations, if that what will permeate the issue up to top decision makers.

How much of this is that the accuracy and process of measurement has improved over the years?
