🧵Since it is becoming hard to track, here is a thread of the simply astounding weather records planet Earth has started shattering in recent weeks:

1. Dramatic flood events have begun striking various countries around the world simultaneously this week.

2. El Niño has rapidly developed in recent months as sea surface temperatures across the equatorial east Pacific skyrocket.

As of yet, the presence of El Niño has not had an impact on global weather conditions. That will change in a few months, however.

3. The entire northeastern Atlantic Ocean is currently experiencing it's most significant marine heatwave ever by a long stretch.

In fact, that area had never been a full 1°C above the 1951-1980 average. It has suddenly jumped to 1.7°C above that average.

4. Antarctica, which is currently in the dead of winter, has unexpectedly failed to reform it's winter sea ice this year.

This is an exceptional deviation from the norm that has left even the most orthodox scientists dumbfounded.

Since I find this to be the most incredible statistic we're witnessing right now, it deserves a second tweet in this thread.

Here's a graph showing the standard deviations of the record low sea ice in Antarctica, which is now above 5σ!

5. An incredibly powerful heatwave has been sitting over southern North America for weeks on end now, with places like Texas and northern Mexico breaking daily record high temperatures for days on end.

This heatwave is moving west.

6. In the Caribbean Sea and Gulf of Mexico, sea surface temperatures are sky-high.

Water temperatures are in the *90s* by the Florida coast, Miami keeps breaking daily record heat index values, and a major coral bleaching event will soon be underway.

7. The Canadian 2023 Wildfire Season will not let up, with nearly all annual records falling before we even reach the midpoint of the season.

No Canadian wildfire season had ever produced 12 terawatts (TW) of fire radiative power. 2023 has produced 18TW.

8. All of these things have culminated in June 2023 easily being the hottest June in recorded history for planet Earth.

It's likely the hottest June in 115,000 - 120,000 years when Earth was last this warm.

9. Finally, 2023 will likely be Earth's hottest year on record.

It will not stay that way for long, however. Another year in the very near future will come along and take over the records set this year.

The climate crisis is escalating. It's time to act.
