Climate change is changing our wind patterns, which is strengthening waves traveling across the earth’s surface.
As climate change has gradually heated oceans around the globe, it’s also been making ocean waves stronger and more deadly, according to a new study published in Nature Monday.
Upper-ocean waves are driven by local wind patterns, which are driven by temperature differences between different layers of the air. So as we pump greenhouse gases into the atmosphere and heat up the air, we’re also strengthening certain wind patterns and weakening others. The net effect on our oceans is stronger winds making stronger waves.
A vertical garden is a garden that grows upward (vertically) using a trellis or other support system, rather than on the ground (horizontally). Anything grown on a trellis or even a fence is technically part of a vertical garden. This technique can be used to create living screens between different areas, providing privacy for your yard or home. More recently, vertical gardens can also be used to grow flowers and even vegetables. vertical gardening is used by many as a means to ensure they are using their garden space to its maximum potential. A simple structure formed by bamboo poles can allow bean plants to climb vertically, providing more growing space than would be possible in a conventional horizontal garden. Cucumbers, squash, and even tomatoes can be grown vertically, as well. Climbing plants and vines are far from the only options when it comes to vertical gardening. With a little planning and the right materials, vertical gardens can be created that allow you to grow virtually anything. A number of DIY kits can be found that use small cups or other containers set in rows in the face of vertical support. These containers are filled with soil and seeds and then watered. Of course, you’re not limited to using a single row of containers set into a vertical surface. You can also use virtually any system that allows you to grow upward instead of outward. This includes scaffolding, shelving systems, and more. Simply create flat surfaces at varying intervals along the vertical axis and add plant trays or pots. Harvesting crops from a vertical garden is significantly easier than with a conventional on-the-ground garden. Because you are able to harvest while standing mostly upright or completely upright (depending on the vertical level being harvested), as opposed to kneeling or squatting on the ground, vertical gardening is easier on the back and legs, and many people with arthritis or other disabilities find it highly beneficial.
Nature has a profound impact on our brains and our behavior.
I’ve been an avid hiker my whole life. From the time I first strapped on a backpack and headed into the Sierra Nevada Mountains, I was hooked on the experience, loving the way being in nature cleared my mind and helped me to feel more grounded and peaceful.
But, even though I’ve always believed that hiking in nature had many psychological benefits, I’ve never had much science to back me up … until now, that is. Scientists are beginning to find evidence that being in nature has a profound impact on our brains and our behavior, helping us to reduce anxiety, brooding and stress, and to increase our attention capacity, creativity, and ability to connect with other people.

Dan Buettner has studied five places around the world where residents are famed for their longevity: Okinawa in Japan, Nicoya in Costa Rica, Icaria in Greece, and Loma Linda in California and Sardinia in Italy.
People living in these so-called “blue zones” have certain factors in common – social support networks, daily exercise habits, and a plant-based diet, for starters. But they share another unexpected commonality. In each community, people are gardening well into old age – their 80s, 90s and beyond.

These days, our kids’ lives are overscheduled, filled with pressure, and can be pretty intense. School, homework, sports and/or other extracurricular activities fill the week and often consumes many weekends as well. We all can feel like there is no time left to fit anything else in. There has to be. Our younger kids and teenagers need wilderness and adventure in their lives and who better to model it to them than us, their parents. I would actually argue that it is more important than a lot of the scheduled activities we have them in now. Wilderness and adventure will help develop them into well-rounded young adults.
Over centuries, even millennia, indigenous communities have developed interdependent systems of agriculture and forestry that are uniquely suited to the ecological requirements of the land they inhabit. Yet even today says Charles M. Peters, a curator of Botany at the New York Botanical Garden, that skill and knowledge often remain unacknowledged, with some government officials and conservationists arguing that indigenous communities should sometimes be excluded from protected lands that are part of their historical territory.
In an interview with Yale Environment 360, Peters — author of the recently published book, Managing the Wild: Stories of People and Plants and Tropical Forests — discusses what he has learned from 35 years of working with indigenous forest communities; explains how indigenous farming, even slash-and-burn agriculture, can actually improve forest health; and reflects on the need to enlist indigenous groups as allies in the struggle to preserve and restore tropical forests.
For people concerned about the environment and climate change, U.S. President Donald Trump has proven to be as bad, or worse, than feared. He is in the process of pulling the United States out of the Paris Agreement, continues to flatly dismiss the science of human-caused global warming, and has worked ceaselessly to undo environmental regulations and weaken environmental agencies.
Now, however, a new leader has emerged on the world stage who is poised to do even more global environmental damage than Trump. He is Jair Bolsonaro, the recently elected president of Brazil, and his extreme views on the environment, coupled with his control of nearly all the country’s levers of power, means that he is now in a position to do unprecedented harm to the Amazon and the international battle to slow climate change.
A growing body of evidence indicates that the continuing destruction of tropical forests is disrupting the movement of water in the atmosphere, causing major shifts in precipitation that could lead to drought in key agricultural areas in China, India, and the U.S. Midwest.
Every tree in the forest is a fountain, sucking water out of the ground through its roots and releasing water vapor into the atmosphere through pores in its foliage. In their billions, they create giant rivers of water in the air – rivers that form clouds and create rainfall hundreds or even thousands of miles away.
But as we shave the planet of trees, we risk drying up these aerial rivers and the lands that depend on them for rain. A growing body of research suggests that this hitherto neglected impact of deforestation could in many continental interiors dwarf the impacts of global climate change. It could dry up the Nile, hobble the Asian monsoon, and desiccate fields from Argentina to the Midwestern United States.

The increase in forest fires, seen this summer from North America to the Mediterranean to Siberia, is directly linked to climate change, scientists say. And as the world continues to warm, there will be a greater risk for fires on nearly every continent.
On a single hot, dry day this summer, an astonishing 140 wildfires leaped to life across British Columbia. “Friday, July 7 was just crazy,” says Mike Flannigan, director of the wildland fire partnership at the University of Alberta. A state of emergency was declared. By the end of summer, more than 1,000 fires had been triggered across the Canadian province, burning a record nearly 3 million acres of forest—nearly 10 times the average in British Columbia over the last decade. As the fires got bigger and hotter, even aerial attacks became useless. “It’s like spitting on a campfire,” says Flannigan. “It doesn’t do much other than making a pretty picture for the newspapers.”
Forest fires are natural. But the number and extent of the fires being seen today are not. These fires are man-made, or at least man-worsened.
What is the best way to save nature – to cordon off areas for parks and open space or to integrate conservation measures on working lands? Recent research makes a case for each of these approaches and has reignited a long-standing debate among scientists and conservationists.
It is one of the biggest questions in conservation: Should we be sharing our landscapes with nature by reviving small woodlands and adopting small-scale eco-friendly farming? Or should we instead be sparing large tracts of land for nature’s exclusive use – by creating more national parks and industrializing agriculture on existing farmland?
The argument between “sparing” and “sharing” as a conservation tool has been raging since researchers first coined the terms more than a decade ago. Arguably it began almost half a century before when Norman Borlaug, the father of the Green Revolution of high-yielding crop varieties, declared that “by producing more food per unit of cultivated area, more land would be available for other uses, including recreation and wildlife.”
