While large parts of the Arctic remain ice free, temperatures remain extremely high compared to normal for this time of year.

Temperature is unable to drop much below freezing where open water remains. In the past, ice cover would allow temperatures to be more like -25 °C.
We are observing the vicious loop which amplifies climate change in the Arctic.

Warmer Arctic = more ice melt = more open water = more energy absorbed from sun in summer = warmer water = more ice melt = more open water...
More on the Arctic sea ice trends in a thread here 👇

It is very important to understand what an anomaly map is. The red colour does not necessarily represent temperature above freezing. It can be -10 °C but still be +20 °C warmer than normal!

The anomaly map takes the current temperature and compared it to a 30 year average.

Extreme and relentless heat in the Arctic has resulted in a shocking lack of Arctic Sea Ice this year.

The refreeze season is millions of square kilometres behind where it should be (orange line). We are in uncharted territory right now.

This is daily coverage since April.
More and more water becomes exposed each decade as the climate warms.

This is how the minimum ice extent varies from 1980 to 2020.

The orange line is a 30 year average from 1980-2010 for this date.
If we average each dace since the 1980s, the trend is clear.

This is the largest glacier in the Alps. Grosser Aletschgletscher, Switzerland 🇨🇭

The glacier concerned in this post is part of a global trend.

The climate is always changing. We know that.

But look at how fast we have changed it recently. Image

Southern Turkey 🇹🇷 and parts of Syria 🇸🇾 are on fire right now.

This is footage from the forests of Turkish Hatay province today.

The recent exceptional heatwave and dry conditions have played a crucial role in exacerbating the situation.

Our planet has just experienced its hottest September on record.

The climate has changed and continues to change.

🔴 = warmer than normal
🔵 = colder than normal

Hotspots: Siberia, Middle East, western USA, parts of South America and Australia.

Data: @CopernicusECMWF

A closer look at the Southern Hemisphere.

Remarkable. ImageImageImage
The world in one map...

Really not much blue (colder than normal going on).

Greenland is more like blueland and La Nina becoming evident.

Wait for it... 140 years of global temperature compared to carbon dioxide trends in 6 seconds.

We cannot blame the sun for our abruptly changing climate.

THREAD [1/7]

Here we go...
To quote @NASA: "The amount of solar energy received by the Earth has followed the Sun’s natural 11-year cycle of small ups and downs with no net increase since the 1950s. Over the same period, global temperature has risen markedly...

... It is therefore extremely unlikely that the Sun has caused the observed global temperature warming trend over the past half-century."

The data speaks for itself. It is not rocket science (no pun intended).

Extreme heat again on the fringe of Arctic.

We are looking at temperatures 15-20 °C warmer than normal in Northern Siberia for consecutive days.

Wildfires continue to rage and sea ice continues to deplete.

Not just Siberia with a heatwave right now.

Some of the hottest parts of Canada right now are within the Arctic Circle. Recently + 33 °C was recorded at Bathurst Inlet (Nu) at latitude 66.8 ° N.
Here are the observations from the weather stations. Likely hotter just to the east of this reading. This is about 20-23 °C above normal for this area.
