- 温暖化を1.5°Cに制限することに焦点を当てています.
- 中国のエネルギー消費と排出量は 世界的な気候目標にとって 極めて重要です
研究 の 目的:
- 1.5°Cの温暖化限界の下での中国の排出経路とエネルギー再構築を評価する.
- 必要な二酸化炭素削減の取り組みと,それに関連する中国の経済的コストを定量化すること.
主な方法:
- マルチモデルの研究アプローチを使用した.
- 排出削減シナリオを"政策なし"のベースラインと比較した.
- セクター別排出量削減の違いと技術の役割を分析した.
主要な成果:
- 中国は炭素排出量を90%以上削減し,エネルギー消費量を39%削減しなければならない ("政策なし"とは対照的に).
- ネガティブ・エミッション・テクノロジーが大きく貢献している (約3%) 2050年までに20%削減する).

01:50Global Climate Change
27.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:16What is Climate?
19.7K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:14Assessing Body Temperature - Oral
1.0K
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

01:27Assessing Body Temperature - Rectal
8.3K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

01:17Radiation: Applications
1.4K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
