March for Jobs, Justice and the Climate: Toronto, Ontario, Canada; July 5th, 2015

Photos and commentary by http://jobsjusticeclimate.ca/:

On July 5th, we made history. In a spectacular demonstration of unity, over 10,000 people marched together in Toronto for Jobs, Justice and the Climate. This is the most diverse climate mobilization ever to take place in Canada.

The March brought together frontline Indigenous communities, Canada’s largest unions, students, social justice organizations and grassroots activists. Together, we sent a clear message: the people of Canada are ready for a new economy that works for people and the planet. By standing in solidarity with one another on July 5th, we have demonstrated that future is possible.

We marched as wild fires sweep across Saskatchewan and communities in South Asia recover from a series of devastating heat waves. The extreme climate events taking place this summer have been another solemn reminder that every minute we delay means more catastrophic and irreversible damage to people and the environment.

We are tired of sitting on the sidelines as world leaders repeatedly fail to deliver the action that we need to combat climate change. Politicians have failed to lead us– it’s clear that people are leading the way.

We know that the economy we need puts justice first by prioritizing Indigenous rights. It is one that secures good work, clean jobs and healthy communities– that means fair wages for all including migrants without status. Ultimately, we have the solutions we need to get there and we know very well who is responsible for the climate crisis.

Thank you for taking part in this historic moment.

How do ice cores preserve temperature records?

Cores drilled through the icecaps in Greenland and Antarctica are our best records of the climate over the last 800,000 years. The best cores literally have 1 band of ice per year, so the ice in each core can be precisely dated. The chemistry of the ice can then show whether there were glaciers present or not….but how do geochemists do that?

Interpreting these records is done in part using isotopes of oxygen and hydrogen.

Ich höre vieles übers Wetter in Deutschland und der Schweiz und wie normal es NICHT ist. Was sind die normalen Temperaturen überhaupt? Ich frage, weil ich nicht aus Europa komme. :)

https://de.wikipedia.org/wiki/Schweiz#Klima

https://de.wikipedia.org/wiki/Klima#Klima_in_Deutschland

Normalerweise ist es in der Schweiz eher kühler als in anderen Ländern. Im Winter kann es an gewissen Orten bis zu unter -20°C werden, meistens ist es aber so zwischen -10°C und 5°C. Der Frühling ist immer wieder unterschiedlich, aber so zwischen 5°C  bis (selten!!) 18°C/20°C. Im Sommer haben wir alles… Manchmal haben wir kalte Sommer & die Temperaturen steigen nicht über 25°C an; manchmal sind die Sommer sehr angenehm und wir haben so 20°C bis 25°C/26°C…. Und manchmal ist es abnormal heiss und wir haben +30°C, aber so richtig normal ist es nicht. Im Herbst ists auch eher kälter, so ca. 10°C.

In den Bergen ist es natürlich kälter und im Süden tendenziell etwas wärmer.

The 5 Most Important Points of Pope Francis's Climate Change Encyclical
We can and must make things better

Hot topic of the moment. Not everyone agrees with the Pope’s encyclical, and I have little ‘faith’ that the environmental community will do anything more than wave the Pope’s call around for political gain. I doubt they (well, ‘we’ since I am clearly part of the enviro-community!) will change behaviors to pivot to help others. We won’t agree to get involved in political decision making (are you going to run for office or go to your city council meetings?). I doubt we’ll make serious and effective efforts to basically reverse the western way of life. And I am firmly confident the enviro-left will absolutely reject his call to reduce investments and dependence on new technologies.

So, what will change because of his call? After all, conservatives and business leaders around the world have openly condemned Pope Francis as a temporary blip. The right are masters of the ad-hominen attack (namely because the media eats it up). The right thinks the Pope no longer has influence. So, to them, it’s not risky to throw a world-religious leader under the bus. For me, I wonder if there are changes, how will people be held accountable if they don’t act? How will possible changes be monitored and measured? Climate denial knows no bounds.  

Here are the five according to TIME:

1. Climate change is real, and it’s getting worse. Though some politicians in the U.S. still argue about the reality of the climate change, Pope Francis doesn’t mince words: “Climate change is a global problem with grave implications: environmental, social, economic, political and for the distribution of goods. It represents one of the principal challenges facing humanity in our day,” he says. “If present trends continue, this century may well witness extraordinary climate change and an unprecedented destruction of ecosystems, with serious consequences for all of us.”

2. Human beings are a major contributor to climate change. While many agree that climate change is real, some believe that human beings don’t contribute to it. The science suggests otherwise, and Pope Francis—a trained chemist—says human beings do have an effect on the Earth: “We have come to see ourselves as her lords and masters, entitled to plunder her at will.”

3. Climate change disproportionately affects the poor. Climate change’s worst impact, Pope Francis says, “will probably be felt by developing countries in coming decades. Many of the poor live in areas particularly affected by phenomena related to warming, and their means of subsistence are largely dependent on natural reserves and ecosystemic services such as agriculture, fishing and forestry.” This environmental inequality creates a strange economic phenomenon: Poor countries are often financially indebted to rich countries. The world has what Pope Francis calls a “social debt towards the poor … because they are denied the right to a life consistent with their inalienable dignity.”

4. We can and must make things better. Some of those who study climate change believe this process to be irreversible, too far gone. But Francis—whose first major letter was entitled Joy of the Gospel—says he doesn’t believe we should be robbed of hope. “Human beings, while capable of the worst, are also capable of rising above themselves, choosing again what is good, and making a new start”

5. Individuals can help, but politicians must lead the charge. Francis argues that personal responsibility is an important step toward reversing climate change, but that political and structural transformations are needed for lasting change. “Every effort to protect and improve our world entails profound changes in lifestyles, models of production and consumption, and the established structures of power which today govern societies.”

Check out this awesome new climate-themed benandjerrys flavor, Save Our Swirled!

“Since the very beginning, Ben & Jerry’s has been a company with a passion for social justice. We’ve advocated for a broad range of causes over the years, and climate change is one we take particularly seriously. While we’ve been working tirelessly at cleaning up our own act and spreading the word around the world, we recognize that there’s power in numbers and know that our passionate fans hold the greatest potential for positive change.

2015 is a critical year for climate change. Later this year, leaders from around the world will gather in Paris, France for the U.N. Climate Summit—a meeting we hope will produce a legally binding agreement to keep global warming in check.

If it’s melted, it’s ruined.” 

Applies to our polar ice and ice cream, too. :(

Warming and Overfishing Sent Seabirds Flocking to California            

Mexico’s elegant terns have begun nesting farther north in years when their traditional food is scarce

by Sarah Zielinski

The Mexican seabirds called elegant terns have had a rocky history. Thanks to invasive species gobbling up their eggs and El Niño events depleting their food supply, the birds have seen their numbers rise and fall for decades. But they weathered those trials and steadfastly held to their traditional nesting grounds off Mexico’s Pacific coast.

Now, however, a one-two punch of climate change and overfishing has the elegant terns moving into California by the thousands, scientists report today in Science Advances.

“The elegant tern is unique to the eastern Pacific,” notes Enriqueta Velarde of the University of Veracruz in Mexico, who has studied the birds since 1979. The terns migrate on a long path from wintering grounds in Chile and Peru north to their breeding grounds on Isla Rasa, in the Gulf of California. Dependent on small fish such as sardines, the birds’ reproductive success has been an indicator of the gulf’s health, accurately predicting food availability for species such as blue whales and sea lions…

Wildfires, smoke continue to spread in Western Canada

Wildfires across Western Canada have forced thousands to evacuate and highways to close, as firefighters from across North America are called in to help.

Compared to last year, Saskatchewan has experienced more than triple the total number of wildfires this season, the government reported.

Dry conditions, strong winds and high temperatures have made it difficult for fire crews to put out the more than 100 wildfires burning across the province, with only seven of those fires contained.

The fires have forced more than 5,000 people to evacuate their homes, with no knowledge of when they might be able to return.

Saskatchewan Premier Brad Wall announced on Saturday that firefighters from South Dakota have come to help battle the blaze.

Wildfires have also hit the rest of Western Canada, with B.C. and Alberta experiencing similar hot and dry conditions.

Port Hardy, B.C. declared a state of emergency on Saturday as a wildfire forced the evacuation of 100 homes. The fire is one of 64 that are active across the province.

There were also more than 120 wildfires burning across Alberta, with hundreds of northern residents put on evacuation alert.

Smoke from the wildfires has triggered health concerns and forced the closure of several highways in Western Canada. The smoke is expected to spread throughout much of B.C., Alberta and Saskatchewan by early next week, as above-normal temperatures climb into the mid-30s.

Many of the fires are believed to have been started by lightning, but fire bans are still in effect for each province. Any tourists planning to travel to Western Canada are asked to make sure they won’t be entering an evacuated area.
