Sentences with phrase «vegetation growth from»

What is known in terms consequences of rising global CO2 levels is a significant increase crop yield and natural vegetation growth from elevated levels of CO2.

An international team of university and NASA scientists examined the relationship between changes in surface temperature and vegetation growth from 45 degrees north latitude to the Arctic Ocean.

Not exact matches

Vegetation across much of the drought - stricken west eagerly soaked up the surfeit of water from the wet winter, leading to a rapid, vast growth spurt in trees, grasses, and shrubs in the spring.

Evidence suggests that the Indians, through the burning of remnants of logs, branches, weeds, crop remains, felled secondary growth vegetation, near - by forest litter, and cut material brought to the fields along with kitchen - fire carbon and ash from the houses, modified the fertility of their soils.

However, the changes in climatic conditions arising from climate change could represent a far more important factor here: i.e. temperatures that increasingly exceed the optimum level for plant growth, like those experienced this summer, shifts in the vegetation periods, and more frequent droughts.

This is because firstly, the micro-organisms that break down dead trees produce copious amounts of CO2, and secondly, there is less vegetation remaining that can remove the greenhouse gas from the air by capturing the carbon in leaves, trunks and roots as part of its growth cycle.

Research conducted by Jin - Soo Kim and Professor Jong - Seong Kug from the Division of Environmental Science and Engineering at Pohang University of Science and Technology (POSTECH), in collaboration with Professor Su - Jong Jeong from the School of Environmental Science and Engineering at South University of Science and Technology of China, has shown that the warmer Arctic has triggered cooler winters and springs in North America, which has in turn weakened vegetation growth and lowered carbon uptake capacity in its ecosystems.

Data from satellite images shows that vegetation growth is lower following a warm Arctic during March.

# 18: «I see a lot of good coming from increased vegetative growth, and more arable land for vegetation to grow in.»

Other than possibly slightly higher sea levels, I see a lot of good coming from increased vegetative growth, and more arable land for vegetation to grow in.

Ultimately, the long - term fate of carbon release from thawing permafrost may be counterbalanced by enhanced vegetation growth.

In the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock - on effects on ocean ecosystems around the globe.»

It uses data on vegetation growth (strictly speaking, «gross primary productivity») from 1901 to 2010.

Plants / vegetation, and other artifacts from humans prior to the industrial age, tree growth that all show significant warming (and cooling) along the way.

Other factors would include dust cloud patterns from the deserts, Smoke from burning vegetation, volcanoes always, Pollen and pollutants, and vegetation growth and cover.

The comparison found that climate change will spark a growth in high - latitude vegetation, which will pull in more carbon from the atmosphere than thawing permafrost will release.

The percent of 14C in released methane or carbon dioxide is different in the old peat than in new vegetation, so it is possible to determine what percent of the methane comes from the thawed portion and what comes from the new growth.

There are two primary externalities that result from our emissions of carbon dioxide into the atmosphere — 1) an enhancement of the greenhouse effect, which results in an alteration of the energy flow in the earth's climate and a general tendency to warm the global average surface temperature, and 2) an enhancement of the rate of photosynthesis in plants and a general tendency to result in more efficient growth and an overall healthier condition of vegetation (including crops).

Altogether, therefore, common sense suggests that with the plant productivity gains that result from the aerial fertilization effect of the ongoing rise in atmospheric CO2, plus its transpiration - reducing effect that boosts plant water use efficiency, along with its stress - alleviating effect that lessens the negative growth impacts of resource limitations and environmental constraints, the world's vegetation possesses an ideal set of abilities to reap a tremendous benefit from what the President inaccurately terms «carbon pollution» in the years and decades to come.

Forests attempting to recover from fires may be hampered by warm, dry weather reducing the growth of new vegetation.

The latest article on greening I've seen is from a couple of months ago: «Human population growth offsets climate - driven increase in woody vegetation in sub-Saharan Africa» https://www.nature.com/articles/s41559-017-0081 Thanks to climate change and CO2 increase the balance is positive towards greening over human deforestation.

The remaining slow drift to lower GMT and pCO2 over glacial time, punctuated by higher - frequency variability and the dust − climate feedbacks, may reflect the consequences of the growth of continental ice sheets via albedo increases (also from vegetation changes) and increased CO2 dissolution in the ocean from cooling.

For Europe specifically, it is estimated that the CO2 flux from land vegetation contributes to reduce the global net flux associated with atmospheric growth of CO2, but the relative magnitude of this sink has been decreasing since the 1990s (from capturing 40 % of the global growth previously, to about 20 % now), likely further to changes in the atmospheric transport of heat and humidity over Europe.
