Global warming is more complex. For example, we have extremely cold summer with lowest night temperatures under 10°C even in July (average low of last years is at least 14°C).

Worldwide , the summer is one of the hottest on record. It's only colder in parts of North America
- alvarlagerlof 6y ago
  Pretty damn cold here in Sweden too
- rangibaby 6y ago
  So far it’s noticeably cooler and wetter in the main island of Japan compared to the last few years

    The relationship between climate and weather can be locally counterintuitive. When a lot of ice starts to melt, you get colder weather. At a smaller scale I got acquainted with this paradox as a child—where I grew up, every spring temperatures drop substantially for a period of time as rivers and lesser ice caps unfreeze. “Why is it getting colder?” “Because it is getting hotter!” At larger scales, if say parts of Arctic melt, that would cool a lot of air, and where this airmass ends up there will be cold weather.

    They are clearly not synonyms. At the very least, notice this difference in your two definitions. 1. A single data point. 2. The average of many data points
    - doublesCs 6y ago
      There's no single data point here. You put a thermometer in the air, it takes a finite time to take a measurement, it's actually averaging over time.

    Weather refers to short-term changes in atmosphere while climate is how we define long-term weather patterns in an area. [1] Saying "climate change is more complex" because you're having a cool summer is wrong, because global warming is a climate-level change and a cool summer is weather. You cannot look at moment to moment or even season to season weather to describe climate change. Climate is usually described in long term trends, e.g., "For the last 50 years, global temperature rose at an average rate of about 0.13°C (around one-quarter degree Fahrenheit) per decade-almost twice as fast as the 0.07°C per decade increase observed over the previous half-century." [2] This is a typical description of climate change, explaining a trend over decades.

[2] https://www.climate.gov/news-features/videos/history-earths-temperature-1880 https://www.climate.gov/news-features/videos/history-earths-... Edit to add, before I put my foot in my mouth: climate does inform weather, so you will see, for example, people saying that the Siberian heatwave are probably influenced by human climate change. Based on the original article, what they're saying is that this event would have been nearly impossible without human contributions.

Sigh. It's local weather versus global climate. In my country it's quite "cold" (for the season) where I live, whereas just 300km south it's hot summer weather as per usual. Also saying the summer is extremely cold when it's not even over yet is quite a stretch - there's about 6 weeks left, 4 of which could just as well become hot.
- pragmar 6y ago
  You're right, but the Siberian heatwave is also a weather event. It's contextualized in climate science, but let's play it out. The article says carbon is a 600x likelihood multiplier. That's one region in one season. What is the likelihood of such an event in any region over 4 seasons? These sorts of stories promote misunderstanding of exactly your point.

Global warming causes more "extremes" to happen and more often in local areas. It's because of how the planet's (now warmer currents) travel, because of how much ice they've already melted at the poles, and so on. All of this means that weather in various local areas is no longer "how it was before". You're going to see snow in areas that never saw snow, you're going to see extremely high temperatures in formerly more temperate areas, etc. Watch some documentaries that show how the North Pole's ice cap is now 70% or less than it was in the 80's (which is also eliminating polar bear populations, as they can now hunt on ice caps for 2-3 fewer months than they were able to do before, leaving them to starvation, etc). Same for Antarctica, where ice is melting much faster than decades ago. You don't think this has global repercussions? These are undeniable changes in the global climate system. They can see seen from one year to the next or one decade to the next with satellites.

Your July experience is very likely just your local weather. No data for July yet, but June was either 2nd or 3rd warmest on record depending on who reports data (EU Copernicus vs NOAA) Previous months were: January - warmest on record February - 2nd warmest March - 2nd warmest April - 2nd warmest, behind by only 0.01 Celcius May - warmest See https://climate.copernicus.eu/surface-air-temperature-maps https://climate.copernicus.eu/surface-air-temperature-maps
