"We know from observations that high temperatures can harm crops, but now we have a much better understanding of the processes," says Bernhard Schauberger from the Potsdam Institute for Climate Impact Research, lead author of the study.
Without efficient emission reductions, yield losses of 20 percent for wheat are possible by 2100 For every single day above 30°C, maize and soybean plants can lose about 5 percent of their harvest. The simulations have shown that the models capture how rather small heat increases beyond this threshold can result in abrupt and substantial yield losses.

Hurricane Ophelia
After the United States was hit with three record breaking hurricanes, the United States receives a break from loss and destruction. Hurricane Ophelia, ran its course toward the United Kingdom on Friday October 13 and since then has rerouted toward Ireland specifically. Ophelia gradually weakened from a category 3 to a category 2 hurricane on Sunday October 14, but picked up speed northeast toward Ireland. Hurricane season is still open as Hurricane Ophelia heads toward Ireland. Ophelia is forecast to produce 2 to 3 inches of rain in Ireland and Scotland. Ophelia's intensity is abnormal as the intensification of a storm usually takes place in cooler regions of the Atlantic. Although Hurricane Ophelia is not a United States concern, the hurricane is still a concern to environmentalist everywhere. The subduction zone off the east coast of the archipelago racks up more intermediate-depth and deep earthquakes than any other subduction zone, where one plate of Earths lithosphere dives under another, on the planet. Analyzing data from several seismic surveys with both ocean bottom seismometers and island-based seismic stations, they were surprised to find a zone of intense earthquake activity in the downgoing slab, which they call a seismic belt.
It looks like the seismic belt is produced by the sudden flushing of water when the slab warms up enough that the hydrated minerals can decompose and give off their water, said Doug Wiens, the Robert S. Brookings Distinguished Professor of earth and planetary sciences in Arts & Sciences at Washington University. Where the double seismic zone started to break down in Tonga, however, we saw this really active area of earthquakes that we named the seismic belt, Wiens said. The faster the slab was moving, the deeper the earthquakes, and the slower the slab, the shallower the earthquakes. A Stanford report has discovered that large marine animals have a higher chance of becoming extinct than smaller creatures. Recent studies have shown that the larger the body mass of the animal is, the greater their chance of extinction. These studies are completely different from what they have been in the past. This pattern is most likely driven by human fishing. The two major groups of marine animals in danger are mollusks and vertebrates. These animals tend to be at the top of the food web , and help cycle nutrients throughout the oceans. Without them, there could be serious problems for the health of the marine ecosystems. This is a pattern that has occurred on Earth before with the massacre of mammoths. This problem can be solved with treaties on how we may hunt and fish. This environmental problem is important because it is caused by humans. More people need to be aware and educated on the problem so it can be stopped before more environmental issues arise.
While this number is higher than the previous estimate made in the late 1990s based on ground measurements, the new research includes data on more volcanoes, including some that scientists have never visited, and it is still lower than human emissions of sulfur dioxide pollution levels. He led the effort to catalogue sulfur dioxide emissions sources from human activities and volcanoes and to trace emissions derived from the satellite observations back to their source by using wind data. With daily observations, tracking sulfur dioxide emissions via satellite can also help with eruption forecasting.
Along with measuring seismic activity and ground deformation, scientists monitoring satellite data can potentially pick up noticeable increases in gas emissions that may precede eruptions. The satellite data could allow us to target new ground-based measurements at unmonitored volcanoes more effectively, leading to better estimates of volcanic carbon dioxide emissions. The work highlights the necessity of consistent long-term data, according to co-author Nick Krotkov, an atmospheric scientist at NASAs Goddard Space Flight Center in Greenbelt, Maryland, which produces the sulfur dioxide data from the Aura satellite. Overfishing in certain coral reefs have begun to cause a positive feedback loop that may soon become unstoppable. Areas where the populations of fish that eat algae have been dwindling, the amount of algae has been increasing. This causes harm to coral reefs, as the algae overpowers the coral reefs, either by using up the available oxygen or by spreading disease to the reefs. What causes the runaway feedback loop is that as algae kills off coral reefs, the amount of area habitable for algae increases.
This shows that even the smallest amounts of human impact can have drastic effects on the health of the ocean and on oral reefs. Something as simple as fishing bottom-feeders can cause a positive feedback loop that can change the composition of a coral reef. This once again shows that people must become increasingly aware of the impacts they have on the environment. Endangerment of BeesBees in the world are on a fast decline. They have declined almost 90% and there are more than 3,000 different bee species.
Without bees in the world we struggle with growing crops and will have to pollinate the plants and trees on our own. A lot of other tree species will die and become extinct without bees around to pollinate them. In Daniel Glick's article "The Big Thaw" Glick explains how the excess burning of fossil fuels and excess green house gasses is part of the cause to global warming as well as the general rise in temperature due to other factors. Flick later explains how this is cause to MASS decrease in glaciers. In Glacier National Park located in Montana has gone from an estimated 150 glaciers to fewer than 30.
Global warming and the melting of these glaciers will lead to mass flooding throughout the world, it could potentially whip out cities even states. This is obviously a global issue and should be handled in some form before anything to serious happens. The Great Barrier Reef is slowly dying due to the rise in temperature of our oceans as well as humans. Yes, humans are a cause to the slow death of the Great Barrier Reef located in Australia. A natural influx of bleach caused to reef to start dying and would usually be able to recover in normal conditions but since we have heated the oceans water we believe that the coral reef will not return to its normal state.
To fix this issue humans should take action immediately! One major issue that faces the coral reef is the over use of burning fossil fuels which release CO2 gas into the atmosphere which is absorbed into the water which kills off certain protectants that the corral consumes. For those of you who do not know there is a huge wildfire spreading throughout Oregon right through Maltinoma Falls. These falls just happen to be one of the most beautiful places in the U.S. This Wildfire is also causing mass air pollution throughout the West Coast. While yes there are other factors causing this air pollution this is one or the more major issues.
Here in California we have about 20 wildfires on top of the large wildfire spreading throughout Oregon. Combined these wildfires are causing horrible pollution for the West Coast making being outside not a ton of fun. |
