Ten percent of the world is facing faster global warming trends than the rest

Around the world, the average global warming trends show an increase of just over 1 degree Celsius (1.8 degrees Fahrenheit) when compared to the preindustrial area. However, about 10 percent of the surface are of the globe has already experienced an average warming of over 2 degrees Celsius. UN scientists refer to that level of change as enough to trigger dangerous climate impacts. Over 70 counties in the United States have already climbed past that milestone.

The higher average temperatures are bringing in more severe storms. That said, it was also pointed out that lakes in New Jersey that used to freeze solid can no longer be used by skaters. Rhode Island waterfront homeowners are watching the sea consume hundreds of their beachfront. Scientists in Minnesota are working industriously to plant new trees in forests dying off from warmer temperatures than native tree varieties are capable of withstanding.

This is far from isolated to the United States. Siberia, Angola, Uruguay, Qtar and many other locations are all watching drastic changes happen as a result of their faster-than-average rising temperatures.

These global warming trends aren’t occurring as a result of specific events or activities. Instead, chain reactions are taking place and are affecting certain areas before others. For instance, melting Arctic permafrost is redefining landscapes in Siberia and Alaska, making lands uninhabitable when they have been occupied for centuries.

Carbon Comeback

While overall global CO2 emissions have been expected to fall by about 7% this year due to the pandemic, scientists fear that the man-made pollution will rebound as the world’s population returns to work and industrial production surges.

Daily global emissions of the greenhouse gas fell by 17% at the height of the COVID-19 shutdown. But levels of transportation and economic activity are able to return to pre-pandemic levels by mid-June, researchers estimate the annual fall in CO2 emissions this year will be only 4%.

Parts of Antarctica are turning green

Parts of the Antarctic Peninsula are changing colour as “green snow” caused by blooming algae is spreading with increases in global temperatures, researchers reported Wednesday.

Although often considered devoid of plant life, Antarctica is home to several types of algae, which grow on slushy snow and suck carbon dioxide from the air. They also found that the majority of algae blooms were within five kilometres of a penguin colony, as the birds’ excrement is an excellent fertiliser.

The polar regions are warming far faster than other parts of the planet and the team predicted that low-lying coastal areas of Antarctica would soon be free from algae as they experience snow-free summers. But that loss will probably be offset by a preponderance of large algae blooms as temperatures rise and snow at higher altitudes softens.

Russia’s global warming rate 2.5 times higher than world average

Russia’s global warming rate is 2.5 times higher than the world average, according to Russian scientists. The rate of global warming on the territory of the country is 2.5 times higher than the average increase in temperatures in the world. This is explained by a variety of factors: the global warming rate in Russia is faster than in the rest of the world due to its location: the country is located in temperate and high latitudes and it is a continental territory.

Pollen Clouds

Vast sheets of pollen have blown across parts of the European landscape this spring, triggering allergy problems for those already suffering from the COVID-19 health crisis.

Images on social media and television have shown layers of yellow pollen reducing visibility in Spain, and Switzerland’s Lake Geneva ringed with yellow from the pollen that had fallen on the water and collected along the shoreline.

Strong winds blowing over vast tracts of olive orchards and other crops that stretch across southern Spain carried the pollen for long distances.

Amazonian Deforestation

Satellite observations by Brazil’s space agency, INPE, confirm that deforestation in the Amazon rainforest rose sharply as the coronavirus crisis deepened in the country during April.

The health emergency has prevented many officials in charge of preventing the practice from being in the field to thwart illegal logging and land clearing. INPE says that losses in Brazil’s portion of the Amazon soared by 64% during the month, with 465 square miles lost.

Despite supporting policies that have encouraged farmers, ranchers and loggers to clear Amazon land to help the economy, President Jair Bolsonaro has authorized the deployment of the armed forces to deter the practices.

Altered Storm Formation

Researchers say that climate change over the past 40 years has altered where hurricanes and the other tropical cyclones around the world are forming.

NOAA scientists say that while the average number of such storms spinning up each year remains relatively stable, more are forming in the North Atlantic and Central Pacific. At the same time, those in the western Pacific and southern Indian oceans are now less frequent.

80% Drop in Freshwater Insect Populations – Global Warming

According to a long-term study in a nature reserve in the State of Hesse, environmental changes attributable to global warming have resulted in an 80% drop in the sizes of freshwater insect populations over the past 40 years.

The Breitenbach, a headwater stream located in the hills of Eastern Hesse, is one of the most intensively investigated watercourses in the world. For more than 40 years, researchers have been following the fortunes of its insect communities. The stream lies within the boundaries of a nature reserve, and its relative remoteness minimizes the direct impact of humans on its flora and fauna.

The analysis, which appears in the journal Conservation Biology, shows that insect communities in the Breitenbach have diminished in abundance by more than 80% over the past four decades. The authors link this alarming decline to climate change.

Global warming to push billions outside climate range that has sustained society for 6,000 years

Just like insects, birds and animals, humans have a particular climate niche, scientists have found, with 6,000 years of human history demonstrating how society thrives when we stay within it and the turbulence that ensues when it is pushed out of this zone.

In a stark new finding about the planet’s rapidly warming climate, a study finds that for every 1.8 degrees Fahrenheit (1 degree Celsius) of global average warming, 1 billion people will have to adapt or migrate to stay within climate conditions that are best suited for crop production, livestock and a sustainable outdoor work environment.

They found that people, crops and livestock have heavily concentrated in a narrow band of relatively constrained climate conditions. This range, referred to in the study as the human “climate niche,” has remained largely unchanged since 6,000 years ago.

Projecting into the future using a scenario with high emissions of heat-trapping greenhouse gases, the researchers found that the position of the human climate niche is projected to change more in the next 50 years than it has during the past 6,000. Such a shift would leave 1 billion to 3 billion people outside the climate conditions that have nurtured human society to date.

Global warming fuels algal bloom in Arabian Sea

A study published Monday in the journal Scientific Reports reveals that global warming is fuelling a destructive algal bloom that is disrupting fisheries in the Arabian Sea.

Cold winter monsoon winds blowing from the Himalayas usually cool the Arabian Sea’s surface, which results in the cold waters sinking and being replaced by nutrient-rich waters below. This process, called convective mixing, allows marine algae called phytoplankton, which provides food for a wide range of sea creatures, to flourish from the nutrient-rich waters lit by the sun.

However, melting glaciers over the Himalyan-Tibetan Plateau region have made the winds blowing to the oceans surface warmer and moister, decreasing convective mixing. This change hurts the phytoplankton, but not the Noctiluca because unlike the phytoplankton, it doesn’t need sunlight.

The ability of Noctiluca to flourish amid the shrinking snowcaps has been disrupting marine life in the Arabian Sea since the late 1990s, the study found. Only jellyfish and salps find the Noctiluca edible.

Highest Ever Level of Microplastics Found on Seafloor

An international research project has revealed the highest levels of microplastic ever recorded on the seafloor, with up to 1.9 million pieces in a thin layer covering just 1 square meter.

Over 10 million tons of plastic waste enters the oceans each year. Floating plastic waste at sea has caught the public’s interest thanks to the ‘Blue Planet Effect’ seeing moves to discourage the use of plastic drinking straws and carrier bags. Yet such accumulations account for less than 1% of the plastic that enters the world’s oceans.

The missing 99% is instead thought to occur in the deep ocean, but until now it has been unclear where it actually ended up.

Researchers have now found that microplastics are delivered to the ocean through rivers carrying industrial and domestic wastewater, carried down submarine canyons by powerful avalanches of sediment (turbidity currents) and then transported on the seafloor by ‘bottom currents’ and deposited in sediment drifts. Other microplastics sink from the ocean surface and can also be picked up and carried by bottom currents.

Global Sea Level Rise

Global sea levels have risen 0.55 inches since 2003 due to ice melt in Antarctica and Greenland driven by climate change, according to new data measurements from several NASA satellites.

Scientists found that Greenland’s ice sheet lost an average of 200 gigatons of ice per year and Antarctica’s ice sheet lost an average of 118 gigatons of ice per year. One gigaton of ice can fill 400,000 Olympic-sized swimming pools.

Carbon Emissions Drop

The United Nations weather agency said that while global carbon emissions are likely to see the biggest yearly fall since World War II due to the COVID-19 crisis, governments should still use some of the new stimulus packages to encourage a move to a greener economy.

The World Meteorological Organization (WMO) cautioned that past economic recoveries have been accompanied by higher emission growth than before the downturns. “We need to show the same determination and unity against climate change as against COVID-19,” said WMO Secretary-General Petteri Taalas.

Storm Fuel

Atmospheric scientists are expressing alarm at the record high temperatures that occurred during March in parts of the Pacific, Atlantic and Indian oceans. They fear the excess warmth will radiate to the air above and generate chaotic weather worldwide during the months to come.

Of particular concern are the future of the Atlantic hurricane season, increased wildfire potentials from Australia and North America to the Amazon and possible severe thunderstorms with accompanying tornadoes. “And there is a global warming component to that. It is really amazing when you look at all the tropical oceans and see how warm they are,” Michelle L’Heureux of the U.S. Climate Prediction Center told Bloomberg News.

Nearly half of Americans are breathing filthy air

The Clean Air Act enacted in 1963 is very nice, but nearly half of Americans breathe polluted air, the American Lung Association reported last week. Climate change is contributing to the situation in multiple ways, including increasing use of artificial environment enhancers – aka air conditioners – as record heat withers the cities, and heaters when record snows and cold descend; and wildfires, which significantly boost soot in the air – one of the many forms of particle pollution. The association points out that particle pollution can trigger “heart attacks and strokes, and cause lung cancer. New research also links air pollution to the development of serious diseases, such as asthma and dementia.” Also, the filthier the air you breathe, the more likely you are to suffer serious consequences if you catch COVID-19.
