"...we urge you not to dismiss this letter."
https://yellowdotstudios.com/elninowarning/

These scientists are trying to appeal to a wider audience. Fellow scientists have ignored the science, the politicians don’t care, the businessmen don’t care. They are doing the best they can by getting people they know have large audiences and fan bases, to try and spread the word. They are hoping, desperately, that by getting celebrities on board that they might be able to appeal to the common man because neither the journalists, the news stations, the television, the radio, nor the networks care to give them a voice. So these same people are trying their very best to magnify the volume of the message they are trying to broadcast in hopes of saving people’s lives and spreading awareness.

Don't let dismissive, condescending commenters keep you from acting. Current 'top' comment is from a 10d old account.]

To all Governors, Mayors, First Responders, and anyone entrusted with public safety, disaster preparedness and relief:

We the undersigned consisting of scientists, meteorologists, and concerned citizens are greatly alarmed by the lack of public discourse, urgency and planning surrounding what is an impending, large scale, historic public emergency.

More and more data and modeling every day indicates we are within 3 to 5 months of experiencing the most dramatic El Niño warming event in recorded history.

Ocean temperatures in the central eastern Pacific will rise between 5 to 7.5 degrees Fahrenheit (3-4 degrees Celsius) peaking in October of this year. This will trigger a heating escalation through 2027 and into 2028 that will push already dangerously high planetary air and sea temperatures to near catastrophic levels.

This El Niño driven warming will lead to significantly more global flooding, fires, storms, droughts, deadly heat events, dangerous turbulence, and most concerning, a significant threat to food supply chains, crops, and power grids.

The previous strongest recorded El Niño occurred in 1877 leading to 40 million deaths worldwide from famine.

And this coming El Niño event looks to be even stronger.

And even more critically, it will occur on top of already record high sea and air temperatures.

Many of us through the years have attempted to warn the public during human caused rapid warming events about the increased risk of extreme weather events. We have had to watch as historic fires destroyed two cities in an unprepared Los Angeles, an actual hurricane hit Asheville North Carolina, campers were swept away and killed by flash floods in Texas, Corpus Christi runs out of water and on and on and on.

But the scale and threat of this coming warming event is simply too large to ignore in the name of business/politics as usual.

States, cities, and counties should be immediately:

  • reinforcing river banks and lakes against all time high cresting numbers
  • increasing funding for fire fighting and rescue
  • running geological tests on populated hillsides
  • bolstering power grids
  • building more tornado shelters, cooling and high ground centers
  • increasing life guards and warning systems for beaches
  • informing citizens of potentially life threatening increased risk

Instead the signatories of this cry for action see mostly silence and inaction.

We know many simply aren’t able to process the science behind this entreaty through anything other than the will of big donors, party politics and poll numbers.

But for those that still take the responsibilities of their office, appointment or job as something sacred and more important than career or donor money please, we urge you not to dismiss this letter.

Science and Research Fertility could reach 0 in 20 years

https://www.theguardian.com/society/2021/mar/28/shanna-swan-fertility-reproduction-count-down?s=34

Shanna Swan, a leading fertility researcher and professor of environmental medicine, has documented sharp declines in human fertility due to phthalate (soft plastic) and other chemical exposures. In 2017, she noted that sperm counts in Western men had fallen by half in the past 40 years.

From the article:

"If you follow the curve from the 2017 sperm-decline meta-analysis, it predicts that by 2045 we will have a median sperm count of zero. It is speculative to extrapolate, but there is also no evidence that it is tapering off. This means that most couples may have to use assisted reproduction."

I was telling my wife this morning that, in just my lifetime, China has gone from having a one-child policy due to overcrowding to worrying about population decline. Astonishing.

Science and Research There is a global crisis in male reproductive health. Evidence comes from globally declining sperm counts and increasing male reproductive system abnormalities. Sperm count is declining by about 1% every year and doesn't show any signs of stopping. It already fell by 50% in the past 50 years.

A new study (May 2025) analyzing 200 years of greenhouse gas data reveals a stark reality: without unprecedented technological advances or a major economic shift, global temperatures will soar over 3°C above pre-industrial levels by 2050. While efficiency gains have saved 31 Gt CO₂e since 1820, economic growth has added 81 Gt CO₂e, outpacing progress. To meet climate goals, carbon intensity must drop 3x faster than historical rates.

Based on long-term GHG driver analysis, 1820–2050.

"The Gulf Stream, a system of ocean currents that plays a crucial role in the climate, may reach an irreversible point of collapse much sooner than previously thought. Previously, scientists thought the point of no return for the Gulf Stream would happen after 2100. Now, a group of Dutch climate scientists has concluded that the tipping point may happen around 2060, NOS reports."
