16-Year-Old Greta Thunberg Cheers ‘Beginning of Great Changes’ as Climate Strike Goes Global
Because “present and future on this planet are at stake,” say teen climate activists, “we won’t be silent any longer”

The world may be edging toward “environmental breakdown”—but 16-year-old Swedish climate activist Greta Thunberg sees signs for hope.
Pointing to global walkouts planned for March 15, Thunberg—whose “school strikes for climate” helped galvanized similar actions worldwide—said, “I think what we are seeing is the beginning of great changes and that is very hopeful.”
“I think enough people have realized just how absurd the situation is,” she told the Guardian. “We are in the middle of the biggest crisis in human history and basically nothing is being done to prevent it.”
In a sign of that realization, thousands of students from dozens of communities across the United Kingdom skipped class on Friday to join the ranks taking part in the weekly climate actions.
In fact, it’s “incredible” that the movement “has spread so far, so fast,” she told “Good Morning Britain.”

My generation trashed the planet. So I salute the children striking back
Across the country today, children left their classes to protest against climate change. This is my message to them

The Youth Strike 4 Climate gives me more hope than I have felt in 30 years of campaigning. Before this week, I believed it was all over. I thought, given the indifference and hostility of those who govern us, and the passivity of most of my generation, that climate breakdown and ecological collapse were inevitable. Now, for the first time in years, I think we can turn them around.
My generation and the generations that went before have failed you. We failed to grasp the basic premise of intergenerational justice: that you cannot apply discount rates to human life. In other words, the life of someone who has not been born will be of no less value than the life of someone who already exists. We have lived as if your lives had no importance, as if any resource we encountered was ours and ours alone to use as we wished, regardless of the impact on future generations. In doing so, we created a cannibal economy: we ate your future to satisfy our greed.
It is true that the people of my generation are not equally to blame. Broadly speaking, ours is a society of altruists governed by psychopaths. We have allowed a tiny number of phenomenally rich people, and the destructive politicians they fund, to trash our life-support systems. While some carry more blame than others, our failure to challenge the oligarchs who are sacking the Earth and to overthrow their illegitimate power, is a collective failure. Together, we have bequeathed you a world that – without drastic and decisive action – may soon become uninhabitable.
Every day at home, we tell you that if you make a mess you should clear it up. We tell you that you should take responsibility for your own lives. But we have failed to apply these principles to ourselves. We walk away from the mess we have made, in the hope that you might clear it up.

El Niño/La Niña Update…
February 2019 ENSO Update: El Niño conditions are here
After several months of flirting, the tropical Pacific ocean and atmosphere appear to have coupled just in time for Valentine’s Day and now meet the criteria for El Niño conditions. Is it true love? Time will tell, but forecasters expect weak El Niño conditions to persist through the spring.
For a few months now, the tropical Pacific has met the first two criteria of our “Is It El Niño Conditions?” decision tree.

That is, the sea surface temperature in the Niño3.4 region of the tropical Pacific Ocean has been more than 0.5°C above the long-term average, and models were predicting it would stay that way for the next several seasons.

What’s new over the past month is that we’re seeing signs of El Niño-related changes in the atmosphere, with increased clouds and rain in the central Pacific indicating a weaker Walker circulation. One measurement of the strength of the Walker circulation, the Equatorial Southern Oscillation Index, was -0.6 during January, indicating more rising air than average over the eastern Pacific, and less than average over the western Pacific. These changes are enough evidence that the atmosphere is responding to the warmer ocean, leading us to conclude we have El Niño conditions!
