Sentences with phrase «global vegetated»

We show a persistent and widespread increase of growing season integrated LAI (greening) over 25 % to 50 % of the global vegetated area, whereas less than 4 % of the globe shows decreasing LAI (browning).

A global satellite study published in the April 2016 edition of the journal Nature reported «a persistent and widespread increase» of CO2 fertilized greening over 25 % to 50 % of the «global vegetated area» over the past 35 years.

Their results show that the fire season has lengthened by an average of 19 % for a quarter of the global vegetated area.

Graphs show a) Global average wildfire season length (expressed as a standardised anomaly), and b) Total global average area experiencing «long» wildfire seasons (as a % of global vegetated area)-- both from 1979 to 2013.

Our ensemble fire weather season length metric captured important wildfire events throughout Eurasia such as the Indonesian fires of 1997 — 98 where peat fires, following an El Niño - induced drought, released carbon equivalent to 13 — 40 % of the global fossil fuel emissions from only 1.4 % of the global vegetated land area (Fig. 4, 1997 — 1998) 46 and the heatwave over Western Russia in 2010 (Fig. 4, 2010) that led to its worst fire season in recorded history and triggered extreme air pollution in Moscow51.

The frequency of long fire weather seasons increased across 53.4 % of the global vegetated area (62.4 M km2) as observed between 1996 and 2013, compared with 1979 — 1996, with decreased frequency only observed across 34.6 % (40.4 M km2)(Fig. 3b).

They estimate that, across about 60 % of the global vegetated area, greening has buffered warming by about 14 %; for the remaining areas, which mostly include boreal zones, LAI trends have amplified the raise in air temperatures, leading to an additional warming of about 10 %.

Not exact matches

We show that fire weather seasons have lengthened across 29.6 million km2 (25.3 %) of the Earth's vegetated surface, resulting in an 18.7 % increase in global mean fire weather season length.

Further, all data sets were masked using the vegetated (burnable) land area defined by a global landcover data set developed from AVHRR satellite data67.

The park's custom - built, naturally vegetated overpasses and underground tunnels allow safe passage — and have set the global standard for animal highway safety.

We show that fire weather seasons have lengthened across 29.6 million km2 (25.3 %) of the Earth's vegetated surface, resulting in an 18.7 % increase in global mean fire weather season length.

If CO2 in the Anthropocene atmosphere contributes to re-vegetating currently arid areas as it did post-LGM, we should expect an even greater warming feedback from CO2 than is assumed from water vapor and albedo feedbacks, due to decreased global dust - induced albedo and increased water vapor from transpiration over increased vegetated area.

Linwood Pendleton of Duke University, North Carolina has produced a paper, Estimating Global «Blue Carbon» Emissions from Conversion and Degradation of Vegetated Coastal Ecosystems, with a large group of fellow - scientists which elucidates this large calculation.

In the article and subsequent aimiable exchange with Nordhaus, Dyson touted no fewer than three possible crackpot mega-schemes as contingency «low - cost backstops» against global warming: «carbon - eating trees» covering fully a quarter of Earth's vegetated land mass, «carbon - eating phytoplankton in the oceans», and «snow - dumping in East Antarctica» (via «a giant array of tethered kites or balloons so as to block the westerly flow on one side only.»)
